Q

Soldering Application of Inherently Flame-Retardant LCP Grades

A

LCP is flame-retardant-free and withstands high-temperature soldering, but drying and orientation management cannot be relaxed; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
