Which Are The Types Of Image Sensors Used In Camera PCB Assembly?

The common image sensor types used in board cameras consist of the following:

CCD Image Sensors

The charged-coupled device (CCDs) are image detectors based on an assemblage of passive photodiodes.

It is an exceedingly sensitive photon detector that is partitioned into numerous light-sensitive small sections (referred to as pixels). The pixels help in the creation of an image of the spot of interest.

The passive photodiodes consolidate charge during the camera exposure time.

Subsequently, the charge is transmitted to the camera PCB which interprets the collected charges of the various pixels and converts them in voltages.

Being a passive-pixel device, the CCD sensor has a very high quantum efficiency. This makes it advantageous in applications where there is poor lighting.

Moreover, you can achieve high pixel uniformity with CCD sensor.

This is due to the fact that the camera PCB is similar for all pixels, or at minimum, pixels of similar column.

However, the transmission of charge is quite slow, leading to low frame rate (usually <20fps). Furthermore, the CCD image sensor technology is not standard, rendering them relatively expensive.

CMOS Sensors

The complementary metal-oxide semiconductor (CMOS) detectors are based on an assemblage of active pixel.

The camera PCB interprets the charge collected within the photodiode into a comprehensible voltage.

Due to this, the camera PCB needs only to acquire and sample each pixel output.

Because the pixel output is dependent on voltage instead of charge, this image sensor type allows you to attain greater frame rates.

This is due to the simpler readout scheme and you can specify region of interest (ROI) to capture.

One of the disadvantages of CMOS sensor is the higher noise because if readout transistors in every pixel.

Moreover, fixed pattern noise, a non-uniformity in the image as result of mismatches throughout the various pixel circuits also causes higher noise.

Camera PCB with CMOS Sensor

Camera PCB with CMOS Sensor

There are two common types of CMOS sensors consisting of:

Rolling Shutter CMOS Sensor

In this readout scheme, all the sensors pixels have the same exposure time. However, there is a hold-up between exposure of a particular row and the subsequent one.

In other words, rolling shutter CMOS sensor architecture is “sequential”. That is, the read-out straight-away following the row exposure time.

It provides an image which is not all recorded at similar time. Therefore, this can pose a challenge in fast Camera PCB applications that need high frame rate.

Global Shutter CMOS Sensor

With this type of CMOS sensor, the exposure time begins and stops at similar time.

Because of this, the information provided by each pixel denotes similar timespan in which you acquire the image.

With global shutter sensor, the only sequential aspect is the read-out. However, the voltage sampled denotes a single specific period of time for all pixel array.

This CMOS sensor type is essential for high speed camera PCB applications.

CID Sensors

Charge-Coupled Device (CID) sensors comprise of a light-responsive surface sectioned into different thousand pixels that are independently addressable by row and column electrodes.

The arrangement enables gathering and readout of electrical signals.

CID consist of 2D assemblage of conjoined MOS charged storage capacitors.

The sensor gathers minority carrier charge produced by photon energy within the Camera PCB substrate close to charge storage capacitors.

It then stores the charge within the surface inversion section.

By transmitting the stored charge in the camera PCB, and tracking the current flow, you achieve signal readout.

Every CID sensor pixel can be independently addressed by electrical indexing of column and row electrodes.

With the CID image sensor, charge does not transmit from spot to spot, which is not the case with CCD sensors.

CCDs transmit the gathered charge from the pixel during signal readout.

In CID, a displacement current equal to accumulated signal charge is registered when camera PCB shifts charge “packets” between capacitors in independently chosen pixels.

The camera PCB amplifies and converts the displacement current to a voltage. It is then relayed as output in the form of digitized signal or video signal.

CID readout is non-destructive because the charge stays intact within the pixel after determining the signal level.

To clear the array of pixel for fresh frame integration, the column and row electrodes in every temporarily switched to ground.

This releases or injects the charge into the camera printed circuit board.

The operation principle of CID sensor technology makes it essentially distinct from other image sensors.

This gives rise to several technical benefits that can be applied to resolve imaging problems.

For example, non-destructive readout ability of CID camera PCBs allows the introduction of high-level of exposure regulation to low-light observation of static scenes.

By halting charge injection, you instigate multiple-frame integration and can observe the image till the optimal exposure develops.

How Does HD Vs. Megapixel Camera PCB Assembly Compare?

Do not consider megapixel camera and HD camera as two different devices.

HD camera PCB assembly is just a unique type of megapixel camera circuit board assembly that complies with certain specifications by SMPTE.

Image Sizes

There exist two primary resolutions for HD camera. They are 720p (1280×720) and 1080p (1920×1080).

Traditional megapixel cameras usually feature a myriad of megapixel resolutions to select from. Therefore, image quality of HD cameras is not as elaborate as with megapixel cameras.

Picture Aspect Ratios

Same as the image size, HD camera PCB module aspect ratio is 16:9. On the contrary, other megapixel camera circuit boards provide a range of formats like 4:3.

Frame Rates

This makes the greatest advantages of HD camera PCB assembly over megapixel camera PCB. Megapixel cameras give exceedingly low frame rates in comparison to HD cameras.

At times they offer as minimum as 4 frames/second in comparison to 30 frames/second offered by HD cameras.

This has greatly been because of processing power of megapixel camera PCB assemblies.

On the other hand, HD specifications requires that images be produced at 25/30 frames per second.

However, the frame rate applicable depends on the country or region.

Progressive Scan

Megapixel camera producers have commonly employed interlaced images to produce megapixel footage.

This basically applies 2 frames to develop the image.

Within the first frame, the camera records lines 1, 3, 5, 7 etc. while the second frame records lines 2, 4, 6 etc.

The cameras as cheap to manufacture though they usually produce blurred images if fast-moving targets items are in view.

Conversely, HD specifications requires progressive scanning of the frames. This is more costly but gives a clearer and brisker image.

The HD standard requires that frames are progressively scanned. This is more expensive but provides a clearer image.

Which Is The Best To Use Between CCD Sensor Vs. CMOS Sensor In Camera PCB?

The two major digital image sensor types used in camera PCB applications are the CMOS sensors and CCD sensors.

There fabrication employs N-type MOS (live MOS or NMOS) or complementary MOS technologies.

Both CMOS and CCD sensors employ MOS technology.

CMOS sensor uses MOSFET amplifier as the building blocks while CCD sensors use MOS capacitors as the building blocks.

Camera PCBs integrated in miniature consumer products commonly utilize CMOS sensors. They are always more affordable and have reduced consumption of power in battery powered gadgets than CCDs.

CCD sensors usually find application in premium telecast quality video cameras.

On the other hand, CMOS sensors reign in consumer goods and still photography where general cost is a key concern.

Both sensor types for camera PCB achieve similar task of capturing and transforming light into electrical signals.

Each CCD image sensor cell is an analog gadget.

When light hits the chip, each photo sensor holds it as a mini electrical charge.

The charges within the line of pixels close to the output amplifiers get amplified and output.

Subsequently, every line of pixels shift it charges a single line nearer to the amplifiers, packing the empty line nearest to the amplifiers.

This procedure is repeated till you amplify and output the charge of all lines of pixels.

CMOS image sensor features an amplifier for every pixel in comparison to the not many amplifiers in the case of CCD.

This leads to reduced area for photon capture compared to a CCD sensor.

However, the use of microlenses before each photodiode helps in overcoming this challenge. The microlenses concentrate light into photodiode, which would have ended up striking the amplifier and go undetected.

Certain CMOS imaging sensors for camera PCB also utilize back-side illumination to raise the amounts of photons that strike the photodiode.

You can implement CMOS sensors with less components, utilize reduced power, and/or give quicker readout in comparison to CCD sensors.

CMOS sensors are less susceptible to static electricity emissions.

CMOS and CCD image sensors are 2 distinct technologies for recording images digitally.

Each features its specific strengths and weaknesses offering advantages in various camera PCB applications.

Which Are The Key Components Of Camera PCB Assembly?

The primary components of camera printed circuit board assembly include:

Image Sensor

The purpose of an image sensor is to detect and transfer information employed in the development of an image.

It helps the camera PCB module determine the image quality.

Be it a digital camera or smartphone camera, sensors serve an instrumental role.

Currently, CMOS image sensor is more common and much less costly to manufacture in comparison to CCD sensor.


This is also another one of the essential parts of camera PCB.

The lens serves a vital purpose in the quality of light that strikes the image sensor hence determining the output image quality.

There are several parameters that you need to consider when selecting the right lens for your camera printed circuit board.

Some of the main considerations include:

  • Lens construction whether glass or plastic lens

BGA Assembly

A ball grid array is a form of surface-mount packaging applied for integrated circuits.

BGA can give more interconnection pins in comparison to flat or dual in-line package.

However, soldering during BGA assembly needs precise control and is normally performed using automated processes.

Box Build Assembly

A box build comprises of all the supplementary work entailed in electromechanical assembly, apart from camera PCB production.

It is at times also referred to as “systems integration”.

The box build assembly is specific to every project and may consist of varying levels of sophistication at every step.

For instance, one step might entail simply putting a camera PCB assembly inside an enclosure. The following step may consist of the sophisticated task of linking the PCB assembly to the user display.

The most popular box build assembly procedures consist of installation of components and sub-assemblies, routing of wire harnesses and cabling, and enclosures fabrication.

Which Are The Applicable Surface Finishes For Camera PCB?

Surface finish is a crucial consideration that influences the camera PCB assembly and the reliability of your board.

It strengthens solder connections and protects copper traces.

There are several types of camera PCB surface finishes that you can choose from including:

  • Hot Air Solder Level (HASL)
  • Organic Solderability Preservative (OSP)
  • Lead-Free HASL
  • Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG)
  • Immersion Silver (Au)
  • Electroless Nickel Immersion Gold (ENIG)
  • Immersion Tin (Sn)
  • Electrolytic Hard Gold
  • Electrolytic Wire Bondable Gold

Making the correct choice for your PCB design needs comprehension of the dissimilarities amongst the available types of surface finish.

Here are some of the attributes of the best surface finish for your camera PCB:

  1. Lead-Free Solder: Should comply with RoHS regulations.
  2. Handling Sensitivity: Factor in the susceptibility to breakage or contamination from handling.
  3. Wire Bondable: Needs to form perfect wire bound connections.
  4. Tight Pitch: Should be utilized with tight pitch components like BGAs.
  5. Contact usage: Should permit use of the contact for contacts.
  6. Shelf life: The surface finish needs to have a long shelf life. It should allow storage for 6 months and more.
  7. Additional cost: The type of surface finish adds to the overall cost of the camera PCB manufacturing.

How Does IPC Component Spacing Guideline Influence Camera PCB Design?

IPC component spacing specifications assist you to create camera PCBs that lessen interference whilst still ensuring the best possible space utilization.

The standard does not define any maximum or minimum size for a board thus the guidelines apply to any size of PCB.

Rather, the guidelines suggest that you decide on the correct size for camera PCB and traces.

The decisions rely on the current amount the board need to carry, in addition to their thermal tolerance.

For drill holes, there is difference in the specifications for internal and external layers of a camera PCB.

Circuits that lie exclusively on the exterior layers of the PCB may be larger compared to those that traverse the internal layers.

You can determine how distant apart circuits need to be, irrespective of the camera PCB size, by employing constants specified in the standards.

Most PCBs have standardized sizes, spanning from a couple of millimeters long to 1/3 of ammeter.

In all printed circuit boards, you should ensure that the leads are as short as practical.

Theoretically, you can apply any angle and orientation to place the leads on the PCB.

However, unusual angles may make it more difficult to model these leads computationally.

As per IPC recommendations, you should place the leads at 45-degrees angle, perpendicular or parallel to one another.

It is ordinary for one camera PCB to feature leads stretching in different directions.

However, leads must never overlap each other.

Overlapping leads would result in contravention of component spacing specifications and could result in too much interference.

Which Are The Two Main IPC Through-Hole Standards For Camera PCB?

There exist two standards; IPC-2221 and IPC-7251, which contains specifications for through-hole components in a camera PCB design.

The IPC-2221 refers to a generic standard covering manufacturing and electrical requirements for circuit board.

Section 9 of IPC-2221 covers holes and interconnection, serving as a perfect citation for PTH design.

IPC-2221 offers comprehensive guidelines on location tolerance, minimum annular ring size, land requirements, and additional applicable fundamentals for through-hole designs.

It also gives image examples of how you should drill and fabricate holes.

IPC-2222 supplements IPC-2221, and it consist of standards on rigid organic PCB.

IPC-2222 has specifications for determining hole size depending on density level.

You can as well get more comprehensive instructions in IPC-7251 document. It is devoted standard for land patterns and through-hole design.

It consists of more specific guidelines, like joint tolerance, component tolerance for different through-hole leads types, and component footprint dimensioning.

Parameters defined in IPC-7251 are usually assigned for 3 levels of producibility:

  • Level A: Standard design producibility
  • Level B: Medium design producibility
  • Level C: Extreme design producibility

Can Camera PCB Transmit Wireless Signal?

Most camera PCB offer a video feed through a composite output of 75 Ohms, however other alternatives are there.

With a built-in power supply, certain camera circuit boards can transmit signals wirelessly.

USB and firewire connectivity are popular when you connect a memory to the printed circuit board.

Camera Printed Circuit Board

Is Impedance Control Important In Camera PCB?

Yes, since camera PCB transfer high frequency signals, there is need to have controlled impedance in design fabrication and performance stage.

However, it is difficult to control impedance, except you watchfully design the circuit board traces and its operating environment.

This is due to the fact that impedance will differ in value from spot to spot along the trace.

At high frequencies, traces do not act like basic circuit connections.

Therefore, controlled impedance assists in ensuring that there is no signal degradation as they travel around the camera PCB.

Controlled impedance refers to the matching of trace locations and dimensions with PCB base materials.

This ensures that trace signal impedance falls within a specific percentage of a defined value.

Controlled impedance camera PCB offer reproducible high frequency performance.

Therefore, you should consider controlled impedance if a signal should have a definite impedance at high frequencies in order to work properly.

It is essential to match the impedance of camera PCB traces so as to maintain signal clarity and data integrity.

When impedance doesn’t match the characteristic impedance of components, there may be increase in switching time, and the PCB may experience random errors.

Why Is Lux Rating Important In Camera PCB Application?

Lux ratings measure the total visible light amount that camera PCB device can see whilst still giving a clear image.

LUX determines the image quality of any camera gadget.

The lesser the LUX rating the lower the amount of light required to develop a usable image (video).

Camera PCB systems that are able to record video/image at LUX value as low as 1.0 or less are better.

Some can even capture footage at 0.003, a LUX value that is much lower.

Cameras capable of recording at 0.0 basically fall under IR camera group and are known as nigh vision cameras. O.0 LUX implies that there exist no light and hence you cannot capture an image, except when it is via infrared imaging.

The LUX rating of camera PCB system depends on three main factors including, “F stop,” sensor chip, and lens.

LUX is denoted in lumens, which is derived from candela.

Which Are The Common Lens Size Options For Camera PCB Assembly?

Sized camera PCB lenses dictate the focus angle for the image sensor. lenses of smaller sizes provide a broader angle.

The common lens sizes for camera PCB assembly include:

  • 1 mm with 150° FOV
  • 8 mm, 115° FOV
  • 6 mm, 92° FOV
  • 6 mm, 53° FOV
  • 6 mm, 20° FOV.

What Is The Meaning Of FOV In Camera PCB Assembly?

The FOV angle denotes the area that the camera PCB lens can cover. It will not be possible to capture the object by the lens if it surpasses this angle.

Lens of camera PCB can cover a broad range of scenes, normally expressed by angle, referred to as lens field of view (FOV).

This is the area captured by the camera circuit board device via the lens at the focal plane to develop a visible image.

The application environment of the camera PCB should determine the FOV. The greater the angle of lens, the broader the FOV, and vice versa.

Which Are The Popular Video Standards Supported By Camera PCB Modules?

PAL and NTSC are the two common types of signal systems that influence the visual quality of footages watched on analog displays.

Moreover, they also affect to a smaller extent visual quality of content observed on HD displays.

NTSC applies 30 frames/second (fps) frame rate at 720×480 aspect ratio.

On the other hand, PAL delivers 25 fps frame rate and an aspect ratio of 720×576.

The PAL color encoding system provides automated color correction in comparison to the manual color correction of NTSC system.

NTSC standard is common in countries like Japan and the United States.

Similarly, PAL system is more popular in countries like Sweden, Australia and the United Kingdom.

There exist a third video standard referred to as SECAM, which is commonly used in France and eastern Europe.

Does The Color Of Camera PCB Matter?

Yes, there are various reasons for selecting a specified color for your camera PCB substrate.

Some colors ensure easier recognition of contrast compared to others with naked eyes, and this could be beneficial during board inspection.

Nevertheless, when working with illumination, as the case with camera PCB, selecting a white PCB can assist in reflecting the light.

In some cases, this extra control offers a broader LEDs options to select from in design optimization.

Based on the camera PCB application, there might be a moment when you need to reflect light.

In such instances, opting for a white PCB is the most appropriate choice.

What Is Included In The BOM Of Camera PCB?

After determining the camera PCB layout and its mechanical limitations, you can now go to full generation of bill of materials.

The BOM, typically generated using the schematic design software, includes the following:

  • All part numbers required
  • Locations of components on the board
  • Design specifications and constraints
  • Quantities of every component

Are Camera PCB Waterproof?

Yes, most if not all outdoor-rated camera PCB assembly are engineered to endure outdoor temperature fluctuations, snow, rain and additional weather conditions.

Generally, when opting for waterproof camera PCB, choose one with higher IP rating.

How Much Is A Camera PCB?

The price of manufacturing camera PCB varies depending on several factors.

Depending on the manufacturer, type of PCB material, board complexity among other factors, you will get different quotes for camera printed circuit boards.

Typically, the camera PCB price ranges from $ 10 to $50 or even higher per piece.

Camera PCB Module

What Is The Importance Of Functional Test During Camera PCB Manufacturing?

Functional test (FCT) serves as the last manufacturing step. It offers a pass/fail decision on finished camera PCBs prior to shipping.

The purpose of FCT is to ascertain that the PCB hardware is defects-free.

These defects could otherwise lead to adverse effects in the functioning of the camera PCB system.

In a nutshell, FCT evaluates the functionality and behavior of the PCB.

It is crucial to stress the necessity of a functional test, its establishment and procedures differ greatly from circuit board to circuit board.

Typically, functional testing entails interfacing to the PCB being tested through its test-probe point or edge connector.

The testing simulates the eventual electrical environment where you will use the camera PCB.

The most popular kind of functional test, referred to as “hot mock-up” basically confirms that the circuit board is functioning correctly.

More complex FCT entail cycling the board through a thorough array of operational tests.

Some of the benefits of functional test include:

  • Functional test imitates the working condition for the camera PCB under test. For that matter, it reduces the expensive cost for you to offer the real testing equipment.
  • It eliminates the necessity for costly system tests in certain instances, which saves on finance and time.
  • It verifies the PCB functionality anywhere from 50 to 100 percent of products being shipped. This minimizes the effort and time needed to verify and debug.
  • Functional test improves others tests like fly probe test and ICT, making the camera PCB more powerful and error free.
