Automotive Pcba factory

The surface of our Automotive Pcba has a copper finish. If they are not protected, the copper will oxidize and deteriorate, making the board unusable. The surface finish forms the key interface between the component and the PCB. Surface treatment has two basic functions, namely protecting the exposed copper circuitry and providing a solderable surface when the components are assembled (welded) to the printed circuit board.

Product introduction:

1. The surface of our Automotive Pcba has a copper finish. If they are not protected, the copper will oxidize and deteriorate, making the board unusable. The surface finish forms the key interface between the component and the PCB. Surface treatment has two basic functions, namely protecting the exposed copper circuitry and providing a solderable surface when the components are assembled (welded) to the printed circuit board.

2. Automotive Pcba has a fine component spacing, so it has a good quality thin coating. It uses HASL as the main surface treatment. The process involves immersing the board in a tin/lead alloy bath and then using an "air knife" to remove excess solder and blowing hot air across the board surface. The HASL process exposes the PCB to temperatures as high as 265 ° C, which will well identify any potential delamination problems before any expensive components are connected to the board.

3. In addition, the immersion tin process used about this Automotive Pcba is a metal structure deposited by a chemical displacement reaction, which is directly applied to the base metal of the circuit board. The underlying metal of the ISn protection is not oxidized during its expected shelf life.

product service advantage :

1 High density, because the surface-assembled components use lead-free or short-circuited wires, I/O end-faced and other packaging technologies, the size of components is greatly reduced, and the I/O terminals are greatly increased, so that the assembly density of the PCB is obtained. A substantial increase.


2 high performance. The lead-free or short-lead features of surface-mount components reduce the parasitic inductance and capacitance of the leads, and increase the high-frequency and high-speed performance of the circuit and the heat dissipation efficiency of the device.


3 low cost. Due to the standardized and non-porous placement features of surface-mount component packages, it is particularly suitable for automated assembly, significantly reducing manufacturing costs.


4 High reliability. Automated production technology ensures a reliable connection of each soldering wire, thereby increasing the reliability of electronic products.


It is precisely because of these four advantages of Smt patch processing that it has promoted its wide application, which in turn has promoted the continuous development of SMT chip processing itself.
