PCABS Halogen-Free Flame Retardant Electronics
Fenómeno del problema
[Problem Phenomenon] Electronic parts require RoHS compliance, and halogen-containing flame retardants are being phased out
Análisis de la causa
Halogen-free flame retardant PC/ABS (phosphorus-based) meets RoHS with low smoke and low toxicity; it does not release hydrogen halide when burned, which is the mainstream direction for electronics and electricals; performance is comparable to halogen-containing types but more temperature sensitive
Solución
Select halogen-free flame retardant PC/ABS for compliance parts; take the lower limit of processing temperature; check the rating and thickness on the UL Yellow Card; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusión clave
Halogen-free flame retardant PC/ABS is the RoHS mainstream, with temperature at the lower limit; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
