Soldering Application of Inherently Flame-Retardant LCP Grades
Fenómeno del problema
【Problem Phenomenon】Connector products requiring UL94 V-0 can directly pass reflow soldering when using LCP, but improper process still causes blistering and cracking
Análisis de la causa
LCP's dense molecular structure is flame retardant, reaching UL94 V-0 without flame retardants, and its high solder temperature resistance allows it to withstand reflow soldering; but blistering and weld line problems are still controlled by drying and orientation; both South China University of Technology and 52by literature have records
Solución
Take advantage of being flame-retardant-free and select pure resin grades; strict drying and temperature management are still required to prevent soldering blistering; keep weld lines away from soldering heated areas and stressed areas; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
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
