The price of PCBA outsourcing includes PCB manufacturing costs, material procurement, SMT/DIP plugins, testing, assembly, packaging logistics, and profit margins.
1. PCB manufacturing cost
The first step in PCBA outsourcing is the manufacturing of PCBs, which includes material costs, production costs, testing costs, and possible engineering costs. The material cost mainly depends on the number of layers, size, material, and surface treatment process of the PCB; The production cost covers a series of processes such as photo painting, drilling, electroplating, etching, solder mask, and character printing; The testing fee usually includes flying pin testing and electrical performance testing; For PCBs with special designs or first-time trial production, additional engineering costs may also be incurred.
2. Material procurement cost
The material procurement cost is an important component of the PCBA OEM material price, which includes the procurement cost of all electronic components, connectors, and auxiliary materials. When purchasing, it is necessary to consider the market price fluctuations of materials, the selection of suppliers, and the increased costs due to disk loading and SMT surface mount losses (about 5%).
3. SMT SMT SMT and DIP plugin costs
SMT (Surface Mount Technology) and DIP (Double In Line Packaging) are key processes in PCBA processing, and the cost of these processes is mainly calculated based on the number of solder joints on the PCB, packaging type, and process complexity.
4. PCBA testing cost
To ensure the quality of PCBA, a series of tests are required, such as ICT (online testing), aging testing, high and low temperature testing, fiber optic signal transmission testing, etc. The testing cost varies depending on the testing items and testing time.
5. Finished product assembly cost
Finished product assembly is the process of assembling a tested PCBA board with other mechanical components, casings, etc. The assembly cost depends on the complexity of the assembly process, the required labor hours, and the use of special tools or equipment.
6. Packaging and logistics costs
Finally, packaging and logistics costs are also an important part that cannot be ignored. The packaging cost includes expenses for special packaging materials, anti-static packaging, etc; The logistics cost is determined based on factors such as transportation distance, transportation mode, and whether customs clearance is required.
7. Profit markup
On the basis of the above costs, the OEM will also add markup based on their own profit margin to form the final quotation. The level of profit margin depends on factors such as the market positioning, brand awareness, service quality, and market competition of the OEM manufacturer.
