Full cost calculation about PCBA board processing price

The price calculation of PCBA circuit board mainly includes the sum of a series of process costs such as component procurement, PCB manufacturing, SMT chip processing, DIP plug-in and PCBA testing. Then, that is to say PCBA circuit board cost = PCB board cost + PCB testing fee + PCB engineering fee (applicable to small batches) + component procurement cost + SMT/DIP welding fee + PCBA testing fee + assembly engineering fee (applicable to small batches) +Special packaging and logistics charges. 

The following Xiaobian will introduce you to the main cost components of PCBA circuit boards.Divided into 4 points：

1. PCB circuit board cost

PCBA circuit board assembly and processing requires you to provide PCB files and BOM list. PCBA assembly and processing manufacturers will make PCB bare boards according to PCB files. The cost of PCB circuit boards is determined according to the difficulty of the process.

2. Component purchase cost

The second part of the cost of PCBA circuit board processing is the cost of component procurement. The PCBA manufacturer purchases the components you need according to the BOM list you provide. When purchasing components, due to the disk loading such as resistors and capacitors and the loss of SMT chips, it needs to cover about 5% of the material loss. Usually PCBA assembly processing Manufacturers have long-term cooperation with component suppliers, so the price will be lower.

3. SMT chip processing fee (SMD chip + DIP plug-in)

To calculate the SMT chip processing cost, it depends on your processing volume. Small batches usually require additional engineering fees. Next, multiply the number of points by the unit price of the points. The unit price of the patch point is between 0.01-0.015 yuan. The number of points is calculated according to 2 feet of SMT patch material and 1 point of DIP plug-in. Just multiply.The specific SMT price calculation can be calculated by clicking on the SMT online quotation.

4. PCBA testing fee and assembly fee

The cost of PCBA testing mainly includes testing labor cost + fixture + auxiliary materials. The cost of testing labor is calculated on an hourly basis. The cost of making test fixtures mainly depends on market conditions. The auxiliary materials are mainly oscilloscopes and computers and other equipment. Adding them together can get the PCBA test cost. Now, add the above 4 parts of the cost, it is the PCBA circuit board processing cost!
