As PCB supplier china knows that,the quotations given by PCBA suppliers are high and low, which affect the main cost of PCBA in the following four aspects:

1. Auxiliary materials: solder paste, tin bar, flux, UV glue, furnace fixture

The quality of solder paste and solder bar is the most important auxiliary material in the whole processing link. Generally, the price of domestic solder paste is 180~260/bottle, and the imported solder paste may be 320~480/bottle, so on the same welding area, The price of imported solder paste is much higher, but the quality of soldering is very different.

2. smt chip processing

SMD processing varies in price depending on the number of points and packages. It is a consensus in the industry that large quantity and good price are the consensus in the industry. The larger the component package size, the easier it is to mount, and the corresponding poor quality will be reduced, so there is also more room for communication on the price.

3. Welding time cost after DIP plug-in

Because the inserting process involves the forming of special-shaped parts and materials, it requires a lot of manual participation. Because there is no reference to the production capacity of machinery and equipment, this part is the most difficult part to control the cost. At the same time, the current labor cost remains high, and the cost of this link is generally high.

4. Assembly test: test fixture, test equipment, test man-hours

The test fixture currently ranges from tens to hundreds of yuan according to the test difficulty, and the test of communication equipment also needs the assistance of optical fiber, ICT and other test equipment, and the corresponding labor and equipment losses need to be considered, but it will not be very high. Some companies even test for free.
