What Are The Costs Of PCB Assembly And Processing?

How to calculate the cost of PCB assembly, many customers will seek a quote from an electronic contract manufacturing services company before outsourcing PCB assembly processing services. In fact, they still have many questions about the final quotation, because many customers may only have two words high or low for the quotation given by the electronic contract manufacturing service company. This high or low may be compared with the quotation given by the manufacturer before. Or the current average price in the industry. If you want to fully understand where the price is high, you need to have a comprehensive interpretation of the entire process of PCB assembly. Now with TECOO for a comprehensive analysis of printed circuit board assembly costs.

Printed circuit board assembly includes three main parts: PCB, component procurement and component soldering (SMT placement/DIP plug-in post-soldering).

1. PCB and electronic components

The price of PCB panels on the market is between 360-480 yuan per square meter, and the prices of components are basically open and transparent in major shopping malls, which can be compared and referenced.

2. Auxiliary materials in the assembly process of printed circuit boards

The quality of solder paste, tin bar, flux, UV glue, solder paste and solder bar for furnace jig is the most important auxiliary material in the whole process. It may be 320~480/bottle, then on the same welding area, the price of imported solder paste will be much higher, but the difference in welding quality is very obvious.

3. SMT chip processing

SMT chip processing will vary in price depending on the number of points and packages. It is a consensus in the industry that large quantity and good price. When products are produced in large quantities, using automated equipment to produce can greatly reduce startup costs and manufacturing costs. The larger the component package size, the easier it is to mount, and the corresponding quality defect rate will be reduced, so there is a greater room for communication on the price.

4. Welding time cost after DIP plug-in

Because it involves the forming of special-shaped parts and materials, this link requires a lot of manual participation, and this link is the link with the most difficult cost control. At present, the labor cost remains high, and the cost of this link is generally high.

5. Assembly test

Test fixtures, test equipment, and test man-hours The price of test fixtures varies according to the difficulty of the test, and sometimes optical fiber, ICT and other test equipment are needed to assist, and the corresponding labor and equipment losses must be taken into account, but the test price will not be very high. TECOO is free of charge for testing its products, and for each product, we conduct 100% functional testing according to customer requirements. For TECOO, our goal is to provide customers with high-quality products and become an inspection-free supplier.

The whole process of printed circuit board assembly and processing includes PCB processing, component procurement and inspection, SMT patch processing, post-soldering of DIP plug-ins, programming test, assembly and other processes. As a professional electronic manufacturing service provider, TECOO can provide one-stop electronic manufacturing solutions for your products and reduce your costs with the most suitable solution.
