In order to discuss SMT chip price and how to calculate SMT chip processing price, it is necessary to fully understand what SMT is, understand SMT process and discuss the price after equipment.

1. What is SMT?

SMT is surface mount technology, which is called surface mount or surface mount technology. It is the most commonly used technology and process in the electronic product assembly industry.
It is a kind of circuit assembly technology that installs the non pin or short lead surface assembly components (SMC / SMD for short) on the surface of printed circuit board (PCB) or the surface of other substrates, and assembles them by reflow soldering and heating welding.

2. SMT process material requirements?

Sheet metal PCB
Material components
Consumable solder paste

3. What equipment does SMT need to complete the process assembly?

Printing machine, SMT machine, reflow soldering three major production equipment.
In the actual production process, there are many testing equipment, SPI, AOI, etc.

4. What technology does SMT need?

A complete set of process flow and problem point control for surface assembly.
Equipment programming technology for equipment use
Quality process of quality control

5. What kind of production environment does SMT need?

Workshop anti-static treatment, temperature and humidity control (temperature 25 plus or minus 2 degrees, relative humidity 40% - 60%), operators anti-static clothing.

6. How to calculate SMT chip price?

Generally, the quantity and type of materials shall be calculated according to the BOM allocation sheet, and the sum shall be calculated according to the formula. Refer to the following table (the solder paste of consumables in production shall not be listed separately, and the expenses generally include appearance inspection, packaging and transportation):
Note: because the SMT process is relatively involved in many links, many product models will be adjusted according to the specific situation.
