PCB prototype assembly cost is combined with the following parts:
Components Procurement Cost
SMT Assembly Cost (SMT +DIP)
PCBA Testing Cost and Assembly Cost
1\PCB Board Cost
Fisrt of all, you should provide the PCB file and BOM list, and the PCBA processing manufacturer will help to make bare boards according to your provided PCB file, when will cause first part of fees, PCB board cost. PCB board cost is determined by the manufacturing process , such as 4 layer board, 8 layer board, Aluminum board, carbon ink board, different board different cost.
2\Components Procurement Cost
PCBA processing manufacturer will help to purchase your demand components. Due to the disk loading resistance, capacitors, and SMT patch loss reasons (such as jumping wrong plate, not promptly removing coil tape, etc.), which need to cover about 5% of material loss rate.
3\SMT Processing Cost ( SMT + DIP)
SMT cost is calculated according to the footpoint of each SMT components with unit price of each point, usually the unit price is among 0.01-0.05RMB.
DIP cost is calculated according to the footpoint of each DIP components with unit price of each point, usually 1 footpoint caculated as a point.
4\PCBA Testing Cost and Assembly Cost
PCBA testing cost is calculated as 2 RMB/pcs and
plus PCBA assembly cost and package cost, which is usually as 0.8RMB/pcs.
PCBA prototype assembly cost is to plus the above four parts cost.
