How to calculate the overall cost of PCBA mainly includes a series of processes such as PCB manufacturing, component procurement, SMT chip processing, DIP plug-in and PCBA testing. According to different processes, the processes involved will be different, so the overall cost quotation of PCBA is relatively complicated.

First, we need to know how the total cost of manufacturing PCBA is constituted, and then break down the cost of each part. The most important thing is the cost of manufacturing printed circuit boards, purchasing components and SMT. The assembly cost of SMT patch includes SMT patch and DIP welding. Capacitor resistance is generally calculated by point, chip (IC) connector is based on pin, and how many pins is a point. DIP is generally the unit price of labor hours divided by the production capacity. Note that the price of DIP is different from the price of manual welding. PCBA manual test costs are calculated on time and the cost of making test fixtures depends on market conditions. For samples order or small order , may we will choose manual soldering, which will save costs. For batches, we will choose automatic equipment, which will help improve production efficiency and save time and cost.
