how to calculate pcb assembly manufacturing cost breakdown? what is the pcba online quote methods?
Let china Topscom tell u,Pcb assembly calculation has basically unified quotation rules in the industry, including pcb circuit board production cost, component purchase cost, assembly cost, project cost, testing fee and subsequent logistics clearance service fee, etc. The PCB manufacturing cost, flying probe test and PCB project cost will be included in the production cost of the pcb circuit board. When purchasing components, it is necessary to cover about 5% of the material loss due to disk loading such as resistance and capacitance and the loss of SMT patch; the assembly cost of SMT patch includes SMT and DIP post-welding, which is calculated separately according to the solder joint and process mode of the circuit board; engineering fees are generally charged for small batches of PCBA assembly, including the cost of process documents, steel mesh, SMT rewiring, etc. PCBA assembly testing fees also need to be included, accounting according to the testing time of each PCBA board; in packaging logistics, special packaging materials and three anti-paint need to calculate the cost, in addition, according to the customer's transaction terms such as FOB, need to calculate additional customs declaration logistics and other expenses.
Typical 2021 pcba assembly cost and quote calculation formula:
PCBA assembly cost = PCB board cost + PCB testing fee + PCB engineering cost (applicable for small batches) + component procurement cost (partially floating 5%) + SMT/DIP welding cost + PCBA testing cost + assembly engineering cost (for small batch application) + special packaging and logistics expenses (if required by customers)
