Every day, people depend heavily on electronic devices to get things done around the house and at their job places. These devices help us cook, clean, and do a host of other activities that would have been difficult or impossible to accomplish without them.

At the heart of every electronic is a printed circuit board (PCB). A PCB is a board that connects various electronic components in a particular device. So how do you choose a PCB that perfectly meets your specific needs?

This friendly guide has all you need to know everything about a custom circuit board and where you can get the best custom circuit boards for your needs.

The Basics You Should Know About Custom Boards

1.1: PCB Prototype Board

In the first phase of developing a custom board. It is much simpler to use a board designed for prototyping. Keep in mind that the fabrication and design of PCB will be required when it comes to adding the final touches to the end product.

1.2: PCB Material

Some of the materials needed for creating a custom circuit board include the copper clad board as well as the positive photoresist. The copper gathers on a foundation that’s referred to as the substrate. Designers can choose between one and two layers of copper, depending on what type of board is in use. There’s a silkscreen that helps make the PCB readable. The substrate, usually known as FR4 (Fire Retardant), works as a thick foundation for the PCB. On top of the copper foil is a layer that’s referred to as the solder mask. It’s usually green in colour.

Some PCBs do not use these materials. Instead, they use epoxies, which have the disadvantage of being thermally sensitive.

1.3: PCB Types

PCBs come in many types, depending on the intended use. The most prevalent custom circuit boards include:

1. Single-sided printed circuit boards

2. Double-sided PCBs

3. Multilayer PCBs

4. Rigid PCBs

5. Flex PCBs

6. Rigid-Flex PCBs

1.4: Printed Circuit Board Components

All electronic components, regardless of their function, have individual components that are essential for various circuits. These components include LEDs, resistors, battery, transistor, switch, diode, and inductor.

How is the Custom Circuit Board Designed?

2.1: The Design Basics

Before we get started on the basics of custom Circuit Board design, we need to get familiar with some terminologies. These include:

2.1.1 Schematic Capture

It is a program that allows the operator to create a schematic diagram of the electronic component as well as other features. In other words, it’s a graphical representation of the element.

2.1.2 Gerber Files

These are computer-aided design files. The files are sent to the custom circuit board producers to assist them in building the PCB structure.

2.1.3 PCB Layout Tool

It is a program that allows for applying on multiple structures of the wiring connection structure. Once the construction is complete, the operator can then generate CAD files to be used to make the custom circuit board.

2.2: The Steps of PCB design

Different makers of printed circuit boards use different approaches when it comes to the designing of a custom circuit boardWe’ve listed the essential steps below:

Step 1: Using of Software

Here, the designer chooses a suitable software to create a custom circuit board. One such software is EAGLE.

Step 2: Generating the Film

Using the finalized PCB diagram, the operator generates the film.

Step 3: Selecting Raw Materials

Where the intention is to design a simple device, the designer can use pocket-friendly material like paper phenolic that’s bonded with copper foil.

Step 4: The Drilling of Holes

Machines and drill bits help to drill holes at this stage. Both a hand machine and a CNC machine are applicable here.

Step 5: Fixing the Image

Here, the designer places a clean copper layer on the printer and stores the designed layout film on the computer before they print the command from the computer using a laser printer.

Step 6: Etching and Stripping

In this stage, the unwanted copper that’s attached to the custom circuit board is removed using different chemicals.

Step 7: Testing

It is the final stage, and it’s meant to ensure that the custom circuit board is fully functional.

Do You Know The Custom Circuit Board Software?

Currently, there’s a wide variety of software available in the market to help design custom circuit boards. Among the top software include: PCB Artist, Altium Designer 17, Ultiboard, DipTrace, SOLIDWORKS PCB, PCBWeb, BSch3V, Gerbv, XCircuit, Eagle PCBs, KiCad EDA, CircuitMaker, DesignSpark PCB, Pad2pad, ZenitPCB, OrCAD, CircuitStudio, PCB123, FreePCB and CUSPICE

3.1 Comparing Various PCB Design Programs

As you’ve seen, the list of software used for PCB design is long. We’ll pick two programs from the catalogue to compare. Of course, we can randomly select these two applications. Let’s take a look at DIPTrace and EAGLE CAD.

3.1.1 DipTrace

This software has many impressive capabilities. The program can perform schematic captures linked to the library. The software can also create patterns using a decent library editor. Users of this program can access tutorial and support. The software is also reasonably priced and has visually appealing colours. Generally, this software is ideal for small and simple custom circuit boards.

3.1.2 EAGLE CAD

This software is capable of electrical rule check, and forward and backward annotation between the PCB and schematic.

3.2. So what’s The Best Custom Circuit Board Design Software?

Given that there’s a great deal of circuit board design software in the market, putting your finger on the best among them is easier said than done. However, some design programs are highly recognizable due to their impressive functionality. One of them is EAGLE. This software is remarkably user-friendly and comes at a moderate price. The software can perform the batch execution of files as well as copper cladding.

Custom Circuit Board Layout Design

4.1: PCB Layout Design

The layout of a printed circuit board requires you to have some technical know-how and calls for the knowledge of software used to make PCB. You also need to be conversant with the computer-aided system used to make PCB, as well as have the skills required for the transfer of the basic PCB design to the final custom circuit board.

4.2: Comparing PCB Layout

When comparing various custom circuit board designs, we look at the following factors:

1. Board size

2. Layers available

3. Power delivery network

4. 3D modelling

5. Differential pair routing

4.3: PCB Layout Tutorial

Step 1: Converting the Schematic to a PCB

Once you have completed the schematics, click on “convert to PCB” on the specific editor you’re using. Doing so converts the schema to PCB.

Step 2: Dragging and Dropping the Component

Here, you place the document to the exact position you want it. If you prefer a neat looking custom circuit board, you can set the components that have a similar function next to each other.

Step 3: Sketch a Custom Outline

Here, you need to go to the layer menu and select the board outline layer. Then you click on the outline and delete it. Next, create your preferred shape using the printed circuit board tools.

Step 4: Copper Area

This step involves joining different parts to one signal. You can create a copper area with the tools menu.

Step 5: Routing

There are two ways to complete the route. Where there’s low current where you’re creating the custom circuit board, use the auto-router function at the top of the page to do it. Where there’s the need for different track sizes, it’s best to do routing manually.

Step 6: Holes

Irrespective of what you’re designing a custom circuit board for, you’ll still need to mount it on something. To create holes on the PCB for this function, use the Hole tool on the tools menu.

Step 7: Adding Pictures and Text

To add pictures and text onto the PCB, go to the tools menu, and stroll to find the text or picture tool. Position your preferred book or make changes as you wish.

Step 8: Photo View

As soon as you’re through with the above steps, it’s the time to view the result. In case you’re not happy with the colour or some other feature, you can change it. If you’re satisfied with the final result, click on “fabrication output.” That helps you buy the custom circuit board.

Printed Circuit Board Reverse Engineering

Sometimes, the schematic is not available. In such cases, you can produce replacement parts using the data created from the PCB reverse engineering. Reverse engineering a custom circuit board can be a tedious and challenging; process, but it still has to be done at times.

5.1 Why We Reverse Engineer PCBs

So why would we bother to reverse engineer circuit boards, given the time and effort involved? Well, here are just some of the principal reasons:

  • To replace components on the PCB that have become obsolete
  • Reposition some of the board components
  • To improve the functionality of the circuit board
  • Analyze and enhance security requirements

Conclusion

Given the enormous role that printed circuit boards play in electronic devices, the PCB you choose must be ideal for your needs.
