After the design process is completed, it must be provided to the appropriate PCB supplier. Then it is necessary to provide complete circuit board documentation to the PCB manufacturer. Complete circuit board documentation is essential, because it provides PCB manufacturers with complete PCB production information, layout, required materials, etc. It also helps to find and solve problems in time, and helps improve PCB assembly speed. Therefore, complete printed circuit board documentation is essential. Some techniques that must be considered when preparing printed circuit board assembly documentation include:
Clear assembly drawing
Before manufacturing the PCB, it is best to have a clear assembly drawing to be used with the design. In order to ensure the successful manufacture of the PCB, the designer must understand everything the manufacturer needs in the drawing.
· Stacked view
During the documentation process, you must specify the different layer sizes and board materials that the manufacturer will use to manufacture the circuit board. You can include detailed information about the material of the circuit board in the drawing notes to ensure that the work is done well during the PCB assembly process.
· size
Includn PCBA) is as error-free as possible. Highlighting your special handling requirements will enable your PCB manufacturer to understand the design.

Questions in the bill of materials
The bill of materials (BOM) is a comprehensive list of all raw materials, components, components, and other basic product manufacturing materials. If the PCB's bill of materials is incorrect, the manufacturer or assembler may encounter some problems during the design and assembly process. The content statement needs to be accurate and with sufficient details to make the printed circuit board assembly meet the customer's specifications.
· Description match
Before handing this work to the PCB designer or assembler, please be sure to provide a detailed description of the appearance of the PCB you want. Your BOM should include basic requirements and other necessary items. If you do not include these requirements, your PCB assembler may ignore these items. Be sure to provide a detailed list of the various parts of the PCB, such as voltage, color, size, etc. By providing this information, the manufacturer will use the correct components for your PCB assembly.
· Correct part number
By listing the manufacturer's part number on your bill of materials, you will ensure on the BOM that the PCB assembler uses the correct materials. Incorrect part numbers can slow down the PCB manufacturing process. Therefore, you must record the correct part number to avoid any kind of delay.
· Complete information
The BOM should contain all the information your PCB manufacturer or assembler needs, and there should be no room for guesswork. Provide a complete list of information to avoid any form of error, which will lead to a waste of time, energy, resources and money. Some of these reports include purchase types, packaging types, flexibility indicators, part numbers, number of parts, supporting documents, placement methods, etc. Make sure to include complete information, as omissions can waste time. If you need to change the information on the BOM, please make sure your PCB designer updates the BOM after the change takes effect.
Gerber File
Gerber is a file format that can be used to provide design data to PCB manufacturers or assemblers. The Gerber file is an open ASCII vector format file that contains information about each PCB layer that will be used by the assembler during the PCB assembly process. For a Gerber file, you have to create an important file, and the assembly will be used to create the PCB. It contains circuit board objects, for example;
1. Copper wire
2. Silk
3. Solder mask
4. Pad
5. Silkscreen pictures
PCB manufacturers usually use Gerber files to convert the details of your PCB design into physical components of the PCB. By properly recording your Gerber file, your PCB manufacturer will build the circuit board according to your specific needs.

Supplier list
When developing electronic device schematics and bills of materials, electronic designers will also improve the approved supplier list (AVL). Must check your supply base AVL. It will enable you to understand the suppliers to keep and the suppliers to abandon. By clearly understanding your AVL, you will understand the company that meets your PCB needs and determine the amount you spend on each supply chain. A detailed supplier list will enable you to improve your negotiation skills and determine the supplier's ranking.
After compiling your AVL, find out more information about them, such as their brand expertise, payment terms, projects, and other important information you need to know before starting business with them.
Be sure to understand the PCB document standard
Must fully understand PCB document standards to ensure the quality of the entire manufacturing process. One way to achieve PCB excellence and accuracy is to comply with the rules of the Electronic Interconnect Industry Trade Association IPC. IPC provides rules for the assembly of electronic devices, and provides training, public policy advocacy and market research.
IPC standards can help PCB manufacturers and assemblers produce reliable and high-performance PCB products that satisfy customers. By complying with IPC standards, your PCB manufacturer will provide quality PCB products, thereby enhancing your company's reputation.
