Electronic assemblies used in mission-critical space applications face unique material challenges that go far beyond typical manufacturing conditions. Adhesives must not only bond and protect, but they must perform reliably in extreme temperature, vibration, and vacuum environments.

Masking eats minutes, and rework slows throughput. Most common application defects in selective coating come back to four variables you can control: chemistry behavior at edges, valve and programming choices, fixturing and board orientation, and inspection timing. Get those right, and overspray and creep typically reduce without slowing the line.

It is critical to minimize mechanical fasteners and protective housings in EV motors due to weight considerations and the speed of assembly factors. Polymeric protectants and adhesives are ideal in these circumstances. There are a number of common applications for high-performance adhesives and coatings within EV motor assemblies.

For the purpose of this article as it relates to the manufacture of printed circuit boards, the definition of flow rate (cubic centimeters/second) will be as follows: the volume of conformal coating (cc) dispensed in a certain period of time.

Conformal coating thickness is one of the most important characteristics to ensure long-term reliability of your electronics.
