문제 현상
[Problem Phenomenon] Electrical parts require flame retardant PC; selection evaluation
원인 분석
PC flame retardant grades (halogenated/halogen-free) reach UL94 V-0; used for electronic and electrical housings and connectors; halogen-free is the trend; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
해결 방법
Select flame retardant PC for flame retardant parts; select halogen-free systems for halogen-free requirements; check the Yellow Card for rating and thickness; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
핵심 요약
PC flame retardant grades are complete, and halogen-free is the electronics trend; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
