This is because this guide explores everything you need to know about remote PCB.

So, keep reading to learn more.

How Many Types Of Remote PCB Are There?

In the current electronic market, you will find two main types of remote control PCB available:

Infrared (IR) Remote PCB

This is a circuit board used in remote control systems to operate video, audio, and other electronics utilizing light signals within IR range.

Using a transmitter positioned at one edge of the IR remote PCB, it relays light signals to the receiver inside another electronic gadget.

Utilizing exceptionally low data rates, normally less than 1,000 bits/sec, IR remote PCB conveys a distinct code for every function on the receiver.

IR remote control PCB needs line of sight to the receiver on the electronic device to be controlled.

There are various types of infrared remote control circuit boards.

They Range from low-cost versions having only a single transmitter to high-quality types that have several powerful IR transmitters.

Radio Frequency (RF) Remote PCB

As the name suggests, RF remote control circuit boards use radio frequency transmission to operate a digital electronic device.

They relay the commands in the form of radio wave to base unit found at the device to be controlled.

The base unit transforms the RF signals to IR signals, which are consequently sent to the device. RF remote PCB can transmit as far as 100 feet away from the receiver.

Moreover, RF signals can penetrate walls since they are not restricted by line-of-site problems.

What Is The Range Of IR Remote Control PCB?

Typically, IR remote PCB can transmit signal up to 10m with perfect conditions, with device physically pointed towards the receiver.

There should be no obstructions and disturbance from other sources of light.

How Does IR Remote PCB Vs. IF Remote PCB Compare?

The table below highlights the common differences between IR vs. IF Remote control circuit boards.

What Is The Difference Between Dedicated Remote Control PCB And Universal Remote Control PCB?

Also known as single device remote PCB, dedicated remote PCB are configured to control a particular device.

This is very common and simple to use and can be both RF or IR in nature.

Conversely, universal remote control PCB is capable to control more than one device of similar or different brands.

This type of remote PCB has infrared codes of several devices or brands pre-programmed in its memory.

All you need to do is key in the brand and model of your gadget. Consequently, the remote PCB will configure itself with the right IR codes.

Alternatively, you may download the right IR codes set for the electronic gadget from its producer’s website, and upload to the remote PCB.

Which Are The Common Data Formats for IR Remote PCB?

The following are the two common IR remote PCB protocols:

RC-5 Code

This IR data format utilizes a bi-phase coding with carrier frequency designated at 36 kHz. The data word transmission starts with 2 start bits succeeded by a toggle bit.

The toggle bit alters its value at every new key-press on the IR remote PCB device.

The 5 address bits designate the address of gadget you want to control, with the 6 command bits constituting information to be relayed.

NEC Code

The NEC protocol employs bursts at 38 kHz carrier frequency.

The NEC code begins the transmission utilizing a lead code, which is a burst having 9 ms length, succeeded by a 4.5 ms pause and eventually the data word.

Are There Bi-Directional RF Remote Control Circuit Boards?

Yes, there are advanced remote PCBs that may employ bidirectional RF links.

Besides the link from the remote PCB device to controlled gadget, there is an extra link backward to the controller from the gadget.

You may use the backward-link for various purposes:

  • Securing the remote link robustness by applying handshake-protocols
  • Providing feedback to the operator: A display incorporated on the remote PCB device might conceptualize data from the controlled gadget.

What Is The Operation Frequency Of RF Remote PCB?

ISM-bands are some of the license-free bands for remote control PCB applications.

The most ideal frequency band for Region 1 (former Soviet Union, Europe, Africa) is 434 MHz.

For South and North America, the frequency is in the 902…928 MHz range. Moreover, the SRD-band at 868 MHz in Europe and 315 MHz frequency band in the US is often applied for remote PCB devices.

ISM-band at 2.4 HGz is an option with global compatibility. Regrettably, 2.4 GHz needs higher consumption of power at corresponding range and thus higher cost.

Realistically, RF remote PCB employs 868, 434 or 315 MHz as the RF carrier frequency.

Why Should You Choose RF Remote PCB?

The importance and advantages of RF remote control PCB are:

  • Its operation is not influenced by line of sight.
  • Passes through walls and penetrates majority of solid materials.
  • Relays signals to extended range in comparison to infrared version.
  • Not sensitive to weather, light, or any environmental elements.

What Are The Main Components Of Remote Control PCB?

The typical components of IR remote PCB include:

  • Integrated Circuit
  • Diode
  • Transistor
  • Resonator
  • Resistor
  • Capacitor
  • 555 timer
  • Infrared LED

Components of RF Remote PCB

All RF remote control PCB have common features as exhibited in the block diagram below.

The key components of RF remote PCB include:

  1. Switches for inputting the command
  2. Microcontroller unit (MCU) for processing of the operator commands to digital messages.
  • RF transmitter (RF TX) for modulation and transmission of the message
  1. Antenna
  2. Battery to supply power voltage to the remote circuit board

How does Infrared (IR) Remote Control PCB Device Operate?

Most remote PCB applications use infrared technology.

The signal between remote control device and the device being controlled comprise of IR pulses that are invisible to naked eyes.

When you press any button found on the handset, the remote PCB transmitter relays a stream of IR signals.

The infrared pulses create a pattern specific to the button you press.

The receiver within the device being controlled notices the makes the device to react appropriately.

Which Are The Modulation Techniques Applied In IR Remote Control PCB?

Most IR protocols employ either of the following methods of modulation designating zero- or one-bits on the 38 kHz frequency carrier.

Pulse Distance Coding

This is the most popular IR coding technique.

Here, the IR remote PCB encode the data through modulation of the period between the signals, whilst the pulse time stays constant.

For instance, the method could encode ‘1’ by a pulse of 500 us succeeded by a space of 1ms. Similarly, it can encode ‘0’ by a pulse of 500us succeeded by a space of 500us.

A trailing pulse will terminate the data stream, which allows you to establish the last space length.

Normally, this encoding technique involves DC components, which is not a concern for IR receivers.

Rather, it is easy decoding the information in microcontroller of the receiver through measuring pulse durations utilizing a timer.

Manchester Coding

This IR coding breaks every bit within the data pulse into a specified span of time. Every time slice represents half space and half pulse.

For example, when it is 800us bit time, you could encode a ‘1’ by pulse of 400us succeeded by space of 400us.

Likewise, the remote PCB would encode ‘0’ by a space of 400us succeeded by a pulse of 400us.

The benefit of using Manchester coding is the fact that it doesn’t involve DC components.

This allows the receivers to excellently regulate the decision point between low- and high-levels.

However, decoding is moderately challenging within the receiver’s microcontroller.

This is because there is need to sense direction of the edge between every data bit.

Pulse Encoding or Pulse Width Modulation (PWM)

This is similar to space coding, save that the remote PCB encodes the data through modulation of pulse width.

For instance, encoding ‘1’ would involve a 1.2ms pulse succeeded by a 600us space. Similarly, the IR remote PCB would encode ‘0’ through a 600us pulse succeeded by a 600us space.

PWM modulation does not require a trailing pulse due to the fixed space length. Also, it is possible to infer the trailing space.

What Are The Parameters To Consider When Selecting Remote PCB Protocol?

When defining or selecting a protocol for remote control circuit board, you need to put these parameters into consideration:

Command Data Frame Bitlength

Lower number of bits with a frame implies lesser energy consumption. Conversely, longer frames permit more payload data content and longer synchronization patterns.

Bitrate

Higher bitrates lead to shorter transmission duration. Nonetheless, higher bitrates need higher bandwidth and quicker receiver hardware for RF remote PCBs.

Reliability

You may increase the link stability through extra error detection bits within the data frame.

Receiver Architecture

Based on the modulation techniques and receiver, the selected protocol should not have DC components.

Furthermore, it ought to give an appropriate run-in-sequence enabling the receiver to adjust to varying media conditions.

Which Are The Modulation Techniques Applied In RF Remote Control PCB?

There is need to modulate the payload data on the radio frequency (RF) carrier.

Essentially, there exist 2 popular simple modulation methods applied in RF remote PCB:

  • Amplitude Shift Keying (ASK)
  • Frequency Shift Keying (FSK)

In most cases, due to energy consumption reasons, ASK is executed as On-off-Keying (OOK). This implies that you simply switch the carrier on and off as is the case in IR remote PCB.

For both OOK and FSK techniques, the transmitters used may be Class-C-power amplifiers, which lead to high power efficiency.

With OOK, it is completely not necessary to modify the carrier frequency.

In this scenario, the ideal choice is SAW‐based transmitters when a specific frequency tolerance is allowed.

Utilizing crystal stabilized PLL-synthesizers facilitate higher output power since they do not require any safety allowances regarding regulation’s limits.

For FSK, you may use SAW‐based transmitters only with certain constraints and skills since the output frequency needs to alternate consistently.

Accordingly, FSK is ideally implemented using PPL-synthesizers that facilitate exact production of both frequencies through digitally switching the PLL divider-factor.

Overall, FSK offer greater robustness against disturbers but at the cost of moderately raised power consumption and higher hardware complexity.

You must use some skill and effort to design the antenna and corresponding network between the antenna and receiver or remote PCB transmitter.

However, modern software tools make it simpler to perform this crucial step.

The challenge is getting an antenna design that designates a perfect tradeoff between performance and cost.

Moreover, a clean RF remote PCB design is critical for compliance with radio regulations.

What Are The Disadvantages Of IR Remote PCB?

The most popular remote control handsets employ infrared technology due to the comparatively affordable IR components.

Nonetheless, these IR remote PCB-based devices experience several drawbacks including:

  • Need for line-of-sight pointing
  • Short transmission range
  • Limited operating angles
  • Reflection problems
  • High consumption of power related to the IR LEDs that results in low battery life.

What Are The Applications Of Remote PCB?

Remote control PCB come in a number of varying shapes, sizes and wireless technologies. They are widely applied in the consumer sector as accessories for a myriad of products like:

  • Video games
  • televisions
  • Stereo systems
  • Fans
  • Air conditioning units
  • Lighting controls
  • Home automation including gate openers/garage door/gate
  • Automobiles having remote keyless entry key fobs

What Are The Main Challenges In Design RF Remote PCB?

The common difficulties PCB manufacturers experience in designing RF remote circuit boards include:

Providing Constant Maximum Transmission Range

Maximizing range of transmission entails relaying as much power as practical but within regulation limits, whilst giving a receiver with exceptional sensitivity.

This is because the overall transmit distance is dependent on both output power of transmitter and receiver sensitivity.

The aim of RF remote PCB design is to configure the output power of RF to the regulations limit.

This signifies that all remote circuit boards must have similar output performance, because they all broadcast within similar limits.

This would be possible in an ideal world however it is basically impossible in the real world having actual components and production tolerances.

It is ideally impractical to broadcast at the optimum power each time with each RF remote control PCB fabricated on the manufacturing line.

Sustain Low System Costs

Among the most essential concerns in any remote PCB design is reducing overall system design cost.

There are various factors that affect design cost apart from component expenses, including inventory, test, labor and manufacturing yield.

Typically, the common low-cost RF remote PCB on the market presently utilizes SAW-based RF transmitter and a microcontroller.

Guarantee Long Battery Life

Battery life is a crucial concern for any portable electronic gadget, particularly a remote control.

Can You Design Remote Control PCB For Security-Sensitive Systems?

Yes, based on the remote PCB application, there might be the need for a guarded link to prevent the controlled device misuse.

For instance, in garage door openers or automotive remote keyless entry.

Appropriate encryption algorithms and rolling-code techniques altering the relayed bit pattern.

That is, with every button-press are often utilized for security-sensitive remote control devices.

The switching of encryption keys incorporates some extra sophistication to the remote control system.

Besides, the encryption and decryption consume extra power despite being executed in microcontroller firmware or a hardware engine.

Remote Keyless Entry PCB

What Are The Necessary Quality Inspection That Remote PCB Should Undergo Before Leaving The Manufacturing Factory?

Majority of PCB manufacturers perform on-off inspection on Remote PCBs prior to leaving the factory.

This ascertains that all circuitries are properly connected.

Currently, some advanced fabricators conduct X-ray inspection in order to detect some flaws on lamination or etching.

For circuit boards requiring SMT assembly, PCB manufacturers normally apply in-circuit test (ICT).

The in-circuit test requires setting of test points during remote PCB design stage.

Immediately issues happen, a special kind of X-ray inspection may be employed as well.

What Factors Influence The Remote Control Circuit Board Price?

Some parameters affect the overall remote PCB cost more compared to others thus you should thoroughly evaluate before starting manufacturing.

These crucial parameters affecting the cost of remote circuit board include:

PCB Material

There are a number of PCB materials that you can select, the substrate materials have a major variation in features and price.

Selection of materials for remote PCB manufacturing rely on various application-based considerations, defined majorly by maximum operation temperature, operation speed and frequency.

Actually, the signals speed or frequency of operation, the more vital is the material choice. For instance, in comparison to ordinary FR-4 material, polyimide raises the cost by about 3 to 5 times.

Size And Number Of Holes In The Board

You will require laser drilling when you are working with super-thin holes. Remote PCB designs that need drilling across 10 or beyond layers, or base materials that are challenging to drill will raise PCB cost.

PCB Trace Width

To prevent overheating issues and transient surges, the remote PCB traces should have adequate width.

Most PCB manufacturers will broaden the trace width and incorporate additional solder mask to tracks that may be susceptible to high capacity.

As a result, this can increase the overall cost of the circuit board.

Surface Treatment

There are many types of surface treatment for PCB. Some finishes pride of higher grades and provide extended shelf life, therefore adding to the general cost of remote PCB production.

HASL is among the popular and less expensive surface treatments, which gives good solderability although has poor rating on other counts.

By comparison, ENIG rates better in most aspects yet just commands a moderate price variation.

Custom Specifications

The custom remote PCB cost will always be higher even when the board is small and comprise of just 1 or 2 layers.

What pushes the cost up is whether unique fabrication skills or tools are needed.

For example, rounded edges, metal edging, and additional solder mask clearance adds to the total cost.

This is in addition to PCB surface finishes of higher grades and an extended lifespan.

Military compliant and higher frequencies remote control circuit boards will cost more because of the high-grade materials and quality testing requirements.

Manufacturer And Lead Time

You will have to pay more if you need the remote PCB manufactured within a short lead time. Also, the PCB manufacturer you work with impacts the overall circuit board price since different manufacturers have differing price matrix.

Each PCB manufacturer have differing focus productions.

There will be considerable difference ask for quote from a mass production factory and quick turn factory.
