However, the material used to make automotive electronic connectors is not unusual. It must:
能 In the assembly process, it can withstand the high temperature of welding and avoid foaming;
➤ In actual use, it can withstand the test of high temperature environment.
Can't ordinary materials work?
➤ About bubbling
When exposed to high temperatures such as reflow ovens, moisture in the parts tends to quickly convert to 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 the JEDEC MSL 1 rating (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.
➤ About heat resistance at high temperatures
The actual operating temperature for some automotive electronics applications can be as high as 200 °C.
In general, conventional materials suitable for these conditions use iodide salts as heat stabilizers. However, these additives may cause corrosion of the metal contacts.
If iodide stabilizers are not used, the thermal stability of the material will be significantly reduced.
A new material that solves these challenges - ForTIi Ace® JTX8
This polyamide material is launched by the DSM Group and offers the following advantages:
达到 Reach the JEDEC MSL Level 1 (Level 1 humidity sensitive level) requirements to avoid foaming during soldering;
➤ Design products with ideal performance and optimize packaging;
➤ Effectively reduce costs and optimize the assembly process for higher productivity;
➤ does not contain a halogen stabilizer, but its heat resistance is comparable to polyphthalamide (PPA) with standard cuprous iodide as a stabilizer;
易于 Easy to color and have excellent color fastness at high temperatures.
