    The Documents and Other Information Required for Customized PCB Boards

    The specific documents required may vary depending on the manufacturer and the requirements of your project, but generally, the following documents are needed: 
    • Schematic diagram: This graphical representation of the circuit design shows the components and their connections.
    • Bill of materials ( BOM ): This list of all the components required for the custom PCB design, including part numbers, quantities, and values.
    • Gerber files: These are the files that contain the design data for the PCB, including the layout, copper traces, drill holes, and other details.
    • Drill files: These files provide information on the size and location of drill holes on the PCB.
    • Assembly drawing: This drawing shows the placement of components on the PCB.
    • Fabrication drawing: This is a drawing that provides information on the dimensions and tolerances of the PCB.
    • Testing instructions: These instructions describe how to test the PCB to ensure that it meets the required specifications.
    • Compliance documents: Depending on the industry and the intended use of the PCB, you may need to provide documentation demonstrating compliance with regulations or standards such as RoHS, UL, or ISO.

    A. The thickness of PCB: For example, 0.4 / 0.6 / 0.8 / 1.0 / 1.2 / 1.6 / 2.0 / 2.4 mm

    B. Copper thickness: For example, 18 um / 35um / 70um / 105um

    C. Surface finishing: For example, HAL ( with lead or lead-free), immersion gold, plated gold, gold-finger, carbon, immersion silver, OSP

    D. Solder mask color: green, white, black, red

    E. Material requirement: it will show what kind of material the customer needs, including TG value or other special requirements like CTI.

    It is essential to work closely with your manufacturer to ensure that you provide all the necessary documents and that the custom PCB design is optimized for manufacturing.

    The Steps in PCB Reverse Engineering (PCB Copy):

    From above, you will know that custom PCB printing need many documents, but some customer lost their documents for their PCB, but they need to make this PCB. So at this point, you need to provide a PCB Reverse Engineering (PCB Copy) service.

    Copying a PCB (Printed Circuit Board) involves duplicating an existing PCB design. Here are the general steps for copying a PCB:

    Obtain the original PCB: You will need a physical copy of the original PCB to create a duplicate. This can be done by purchasing or borrowing the PCB from the original manufacturer or by creating a physical copy using a scanner or digital camera.

    Design the PCB: Use PCB design software such as Altium Designer, Eagle PCB, or KiCAD to create a new custom PCB design based on the original PCB. Use the original PCB to reference the placement of components and routing of traces.
    Generate the Gerber files: Once the new custom PCB design is complete, generate Gerber files which are the standard format used for manufacturing PCBs. The Gerber files contain all the information necessary for the PCB manufacturer to create the board.
    Choose a PCB manufacturer: Finding a PCB manufacturer is not difficult; choosing one that meets your desired specifications and requirements can be overwhelming. Be sure to make your choice carefully.
    Submit the Gerber files: Submit the Gerber files to the PCB manufacturer for manufacturing. Review the manufacturer’s requirements for submitting the files and any additional specifications.

    Verify and test the copied PCB: Once the manufacturer has completed the PCB, verify that the copied PCB matches the original PCB in size, component placement, and routing. Test the copied PCB to ensure it functions as expected. This can be done using a circuit tester, installing it in the intended device, and running tests.

    It is important to note that copying a PCB without permission from the original manufacturer may be illegal and can lead to legal consequences.

    The Materials Used for Custom PCB:

    Custom PCB can be made from various materials, but some of the most commonly used materials Viasion used are: 

    This is the most widely used material for PCBs due to its low cost, high strength, and excellent electrical properties. It is made of woven fiberglass cloth impregnated with epoxy resin.

    Polyimide (PI)
    PI materials are used for Flex PCB. Flexible PCBs are made of a thin, flexible plastic material that can be bent and folded to fit into tight spaces. It would be wrong to assume that these boards are unsuitable for medical devices, automotive sensors, and other applications where flexibility is essential. The truth is quite the opposite.
    Ceramic Material

    Ceramic PCBs are used in high-temperature and high-power applications due to their excellent thermal properties. These boards are made of a ceramic material with a layer of copper on either side.


    Rogers is a brand of high-performance laminates commonly used in RF (Radio Frequency) and microwave applications. These laminates are made from a ceramic-filled PTFE (Polytetrafluoroethylene) material that offers excellent electrical properties.


    Because of its excellent heat dissipation properties, aluminium PCB is often used in high-power applications, such as LED lighting. These boards have a metal core with a layer of dielectric material and a layer of copper on either side.

    Metal Core Material

    Metal Core PCBs (MCPCBs) are used in applications that require high thermal conductivity and heat dissipation. These boards have a metal core with a layer of insulating material and a layer of copper on either side.

    High reliable materials

    High reliable materials are always used in high-tech PCBs, such as multilayer PCBs, blind and buried vias PCBs, and HDI PCBs etc.; these boards are often used in smartphones, tablets, and other portable devices. So high reliable material is needed.

    Custom PCB Manufacturing Techniques

    A custom printed circuit board is a unique electronic device designed for specific purposes. It is custom-made from start to finish and tailored to the customer’s exact specifications. The production process of custom PCB mainly includes photolithography, laser drilling, through-hole plating, silk screen printing, solder mask application, and final testing.

    Photolithography uses a light-sensitive photoresist, UV exposure and chemical processing to create custom circuit patterns on the PCB. The laser drilling process uses lasers to precisely drill holes in the custom circuit board for component placement. Through-hole plating is needed to protect the custom board from corrosion. Silk screen printing is used to create custom board markings and labels. A solder mask is applied over the custom circuit board for further protection. Finally, custom PCBs are tested for flaws or errors before being shipped.

    Customers can get what they need with custom printed circuit boards without worrying about compatibility issues or unnecessary add-ons. As a result, custom PCBs are an excellent option for those who want to create custom electronic products that meet their specifications.

    When it comes to electronics manufacturing, custom PCBs play a critical role in ensuring the efficient and reliable operation of electronic devices. Some familiar with the PCB industry may say, “PCBs are an essential component of electronic devices that provide the electrical connectivity between different components, right?” Yes, you got the point. They serve as a backbone of the electronic circuit and enable the smooth transfer of data and power between different components.

    In recent years, the demand for custom PCBs has grown significantly due to the increasing complexity and diversity of electronic devices. Custom circuit boards offer numerous benefits, including higher functionality, better performance, and improved reliability.
