PCB Assembly

A PCB prototype design work is a pleasant experience. However, before contacting  your PCB assembly supplier to mass fabricate your product, some preparations are required to guarantee a smooth PCB assembly process. You will find that some steps are added compared to your PCB manufacturing process.

Please take the following points into considerations before assembling your circuit board by your PCB assembly supplier.

Assembly instructions-- There are occasions where you need onboard jumpers to be soldered or do not fill some certain components. Be sure to write these down into a special assembly instruction list to avoid any miscommunications.

BOM list-- The BOM list is important for PCB assembly suppliers to double check and ensure the right components are installed on the PCB. Before sending it to your PCB assembly supplier, update your BOM checklist to express your expected final product.

Manufacturing files-- The assembly machine relies on the manufacturing files to accurately place components on PCB boards. Make sure you have sent the same file used for your PCB manufacturing to your PCB assembly vendor.

QC Test-- In addition to PCB assembly services, some suppliers also provide QC test services. If you need your assembly supplier to do some basic functional tests, you need to prepare the test procedure.

Sample PCB-- If you can send a sample PCB with all right components mounted to your assembly supplier, the assembly errors will be largely reduced, because it gives them a great idea on the component placement before sifting through your BOM list and instructions.

PCB Stencil-- If you have surface mount components on your board, you will need to order stencil from your supplier. The problem is that by putting all the surface mount components to one side, you can save the cost of reducing the number of PCB stencils.
