What are the Design Benefits of Black Solder Mask PCB?

The black PCB is highly versatile meaning the board can be covered with coatings of different properties depending on your needs.

Therefore, it is very important to consider properties such as mechanical, electrical, and moisture resistance to make the PCB suitable for use effectively.

Adding to that, the black PCB is visually appealing especially when the board holds shiny metal components on the circuitry.

Low reflection to light; black is a poor reflector of light hence used in places where the reflection of light is not needed

The board makes it hard to plagiarize since the copper features are difficult to figure out when looking with the naked eye. Therefore, making it difficult for one to pirate by simply following the board design traces.

Due to its high cost of production compared to other boards, it makes it hard to plagiarize also.

Which are the Applicable Methods of Black PCB Etching?

Some of the main applications include:

Chemical Etching

Usually done using ferric chloride or ammonium persulphate. The two are corrosive liquids that will dissolve away unwanted copper to define the desired circuit.

Plasma Etching

Plasma is generated under strict conditions and used to clean the materials left behind in the holes drilled on the black PCB.

Laser Etching

This is the process of removing a fine layer of a photosensitive black PCB with a laser beam to expose the copper beneath. The copper is corroded through an acid birth.

How do you Etch Black PCB?

You have to follow the steps below when you are etching your black PCB:

Design and Print out your Black PCB Schematics

First, design the PCB using your desirable software design and then print out the layout on glossy paper using a solid ink printer.

Slice Up and Sand the Copper-Clad

Here, cut many layers that you require of the same size from copper-clad and sand them. You should focus the sanding on the edges of the copper-clad to get a nice etching.

  1. You then transfer the circuit to copper clad using either a heating element or a heatless toner method. The method one is supposed to use will suit their needs.
  2. Start Etching

When using the chemical etching process, place your copper clads in ferric chloride solution for about 8 minutes. After this, check the traces and remove the unwanted copper between the traces.

Rinse, Clean, and Inspect the Black PCB

After completing your etching process, the black PCB using clean tap water. Then clean the board by rubbing alcohol on it to wipe away the excess ink on the black PCB.

Finally, you check on your board to ensure all details are in place.

Which are the Methods of Surface Mount Technology Applied in Black PCB?

  • Type 1A Assembly; here the surface mount components are soldered only on the component side of the black PCB. It is the simplest form of assembly.
  • Type 1B Assembly; consists of surface mount components on either side of the black PCB. Therefore, its functional density is very high.

You can attain large space savings here. Also, components on the secondary side are placed first using adhesive and then reflowed.

  • Type 2 Assembly; the primary side of the black PCB contains both through-hole and surface mount components. Here, the secondary side contains components for surface mount.

What is the Difference between Soft Soldering and Hard Soldering of Black PCB?

Soft soldering is only applicable in black PCB materials that require a temperature of less than 400 ◦C.

Here, you apply heat at the filler metal ends where they are supposed to be joined and the heat connects the workpieces strongly. The soft lead is the basic requirement of this soldering method.

Hard soldering of black PCB is sometimes referred to as silver soldering. The required temperature is more than 480 ◦C. It produces stronger joints compared to the ones formed from soft soldering.

Here the solder unites two elements of metal by spreading it onto the holes of components that are unlocked due to high temperature.

Which are the Important Guidelines to Follow during Black PCB Routing?

Black PCB routing helps you connect your signal traces to match your design guidelines.

It is recommended that you always place your traces directly as possible between components.

Your components will be route traced vertically on the opposite side.

This applies In case the component placing forces a horizontal trace routing on one side of the board.

When the number of layers in your stack increases, the routing guidelines become more complex.

This means that your routing strategy will be alternating horizontal and vertical traces in interchanging layers.

Which are the Key Black PCB Tests to Perform?

  • Burn-in Testing; used to detect early failures and also establish load capacity.

Due to its intensity, this test can at times be destructive to parts being tested. This test will push power through your electronics usually at its maximum capacity for around 48- 168 hours continuously.

If the black PCB board fails it is known as infant mortality, and boards with high infant mortality are not appropriate.

  • X-Ray Inspection; this type of test is more of an inspection tool.

During this type of test, the technician can locate tests early during the manufacturing process. It also checks elements that are hidden from being seen such as connections.

  • Automated Optical Inspection; mostly used to detect problems early to ensure that production is stopped early.

It incorporates either 2D or 3D cameras that take photos on the black PCB.

After that, the software then compares the photos of your board to a detailed design.

If by chance there is a board that does not match the design to the required level, then it is flagged for inspection.

  • Flying Probe Inspection; the test works through the use of needles attached to the probe on an x-y grid obtained from basic CAD.

A black PCB flying probe inspection does not power up the board.

  • In-Circuit Testing; is the most robust type of black PCB testing in existence.

The test involves the use of fixed probes laid out in a way that matches the design of the black PCB. These probes will check the integrity of the solder connection.

  • Functional Testing; here the functional tests and specifications are provided by the customer. It takes a lot of time but saves face and money.

 Quality Testing of Black PCB

What are the Disadvantages of Black PCB?

  • Susceptible to Roughhousing; black PCBs are incapable of handling scratches and bumps. Small scratches or bumps will result in undesirable blemishes on the surface of the black PCB.
  • Low Surface Resolution; the trace paths on the black PCB board are hard to visualize without the use of decent light.

This is because of the low resolution of routing paths on the boards making it difficult for designers to work on the boards.

  • Slight Toxicity to Blank Ink; using blank inks in the manufacture of black PCB boards is a little bit more toxic. The ink is more expensive compared to other inks but its chemical composition makes it more toxic.

Which are some of the Design Problem Encountered during Black PCB Manufacturing?

  1. Acid Traps; is a common term for acute angles in a circuit. This is because these acute angles trap acids during the process of etching.

The angle keeps the acid in a corner for longer periods than design calls for, causing the acid to eat more than intended.

This, later on, causes the design to be defective, compromise the connection, and cause serious problems later on.

  1. Missing Solder Masks between Pads; the solder mask acts as an insulator for copper traces against accidental contact with other metals.

When the solder mask is partially or absent between pads, it exposes more copper than is necessary. This will result in reduced corrosion prevention and affect negatively the functionality of the circuit board.

  • Bad soldering; happens during the assembly process. This occurs when the solder is not heated enough leading to cold soldering which causes black PCB failure.
  1. Slivers; are small wedges of copper or solder mask generated during the black PCB manufacturing process.

They cause problems in manufacturing of the black PCBs. These slivers are generated during the etching process and detach when fully dissolved hence adding unintended connections.

  1. Poorly Manufactured Components; another failure occurs when one uses poorly manufactured components.

Physical damage due to improper components used during the assembly will harm the black PCB and cause power failure.

How do Linear Distortion and Non-Linear Distortion in Black PCB Compare?

In linear distortion, the sources do not generate harmonics. On the other hand, sources of non-linear distortion generate harmonics as the signal propagates through the source.

What are the Effects of Harmonic Distortion in Black PCB?

When harmonic distortion occurs, the black PCB heats up. This leads to difference in output and input of the circuit which is supposed to be the same.

This is harmful to the circuit since it causes power loss and overheating of the board.

To control overheating, a heat sink is required which in turn makes the black PCB expensive.

Which Design Parameters do you Consider during Design Rule Checking (DRC) of Black PCB?

  • Minimum Width; the DRC will check whether the width of the VCC and GND are at per with the design parameters of the black PCB.

It will also check whether there is a tight coupling between the power supply and the ground wire.

  • Minimum Area; you run the DRC to check whether the overall size of board and that of its components conforms with the total allowable area. It notifies the designer if the board goes outside the defined black PCB outline.
  • Silkscreen Shots; here, the DRC will check whether the labels and icons added on the black PCB will cause any shorts. If so, it will alert the designer to change accordingly.
  • Misaligned Via Wires; you use the DRC to check whether two different layers of the same logical net have aligned via a connection or not. If the inserted via is not aligning with metal crossing, it raises a via misalignment flag.
  • End of Line Spacing; DRC checks to ensure whether the outer ream of power layer in multilayer black PCB is reduced to desirable standard or not.
  • Minimum Spacing; this parameter checks the minimum spacing present between the onboard components.

The DRC will also ensure that spacing between traces and pads, traces and through-holes are reasonable or not.

  • Analog and Digital GNDs; the DRC checking rule will ensure that all analog and digital circuits present on the black PCB have separate grounds.

Why are Gerber Files Necessary in Black PCB Manufacturing?

Gerber files are described as open ASCII vector format files that have information on each layer of your black PCB.

The Gerber files are necessary because without them, the manufacturer will not be able to understand the details of the PCB design. Therefore, the Gerber files serve as both the reference and guideline to be used by the manufacturer.

What is the Difference Between RS-274-X/X – Gerber and Gerber X2 Versions of Black PCB Gerber File?

Gerber RS-274-X/X- Gerber is used in human-readable ASCII commands that are put together to produce a 2D vector graphic.

It is also consolidated to use metadata that defines graphics.

Whereas the Gerber X2 supports all extra vendor extensions and is well-matched with most modern CAM software applications.

Adding to that, Gerber X2 is an improvement of X-Gerber.

What Information is Contained in Black PCB Gerber File?

The black PCB Gerber files contain the following information that guides and help the manufacturer in the production of the PCB:

  • Configuration parameters.
  • Draw and flash command codes.
  • Macro and aperture dimensions.
  • XY coordinates locations for draw and flash commands.

Which are the Coats you can Use in Black PCB Coating?

Coating in black PCBs is very important as it boosts the safety of electronic devices. You can coat manually or automatically depending on your choice.

There are different types of coats you can use when coating your black PCB.

  • Varnish; this type of coat is moisture-resistant and has high insulation and stability properties.
  • Acrylic; this type of coat will provide your black PCB with good protection and elasticity. They are not complicated hence can be applied easily and can be removed easily if the need arises.
  • Silicone; these types of coats will provide the black PCB with great temperature protection and are appropriate for chemical resistance.
  • Urethane; protect the black PCB against chemical and mechanical attacks that are prone to happen.

These coats are also suitable for moisture resistance.

Are there Gloss and Matte Black PCB Solder Mask Options?

Gloss black solder mask is light reflective and lighter in color whereas the matte black solder mask has no shine and appears darker.

The gloss black solder mask will tend to present a hard-shell finish which makes scratches more visible.

For the matte black solder mask, the finish is softer hence prone to scratches. Depending on where you will use your black PCB, the two can be used as your solder mask options.

Are Black PCB Boards more Advanced?

The difference between black PCB and other color PCBs is the solder mask color but the design and manufacturing process is similar.

Since it is hard to plagiarize black PCB because its traces cannot be distinguished by the naked eye. This makes people think it’s more advanced.

Also, most high-end products use black PCBs in their electrical connections making people think it is high-end.

Lastly, the cost of production is increased and lures people to think its high quality and more advanced. The reason for this is increased difficulty in production and maintenance of the black PCB.

What Information should be constituted in the Pick and Place (X-Y) File of Black PCB?

The Pick and Place (X-Y) are helpful for automated SMT component placement.

The machine helps save on time and improves accuracy and this applies only to surface mount components.
