How to calculate PCB assembly cost, many electronic manufacturers will look for quotation from processing manufacturers before outsourcing the processing services. In fact, they will still have a lot of doubts about the final quotations, so we are going to conduct a comprehensive cost analysis of PCB assembly. First, Required Material Costs Before Assembly According to the customer’s BOM list, the purchasing department of the processing firm will make an inquiry, including PCB bare board, electronic parts, etc. Sometimes, assembly costs and engineering costs will be included in purchasing quotation. It needs to cover about 5% of the material loss when purchasing the components, due to the reason of material loss, like resistance and capacitance disk loading material and SMT chip. For the small batch of PCBA, engineering costs are usually covered in quotation, including the costs of processing file, stencil, Changing SMT line etc. Then, Solder Joint Counting PCB assembly
