The material used to make automotive electronic connectors is not general, it must:

1. During the assembly process, it can withstand the high temperature of welding and avoid foaming;

2. In actual use, it can withstand the test of high temperature environment.

Can't ordinary materials work?

1. About bubbling

When exposed to high temperatures such as reflow ovens, moisture in the parts tends to be rapidly converted into steam, causing foaming. Foaming can affect assembly and impair the mechanical properties of the assembly. To avoid such problems, the automotive industry's requirements for connectors are moving closer to JEDEC MSL 1 (Grade 1 humidity sensitivity).

Although some existing thermoplastics may also meet the JEDEC MSL 1 rating, due to the brittleness of the material, weak weld lines or low heat peaks, the product often needs to be compromised in performance.

2. About heat resistance at high temperatures

The actual operating temperature for some automotive electronics applications can be as high as 200
