PC electronic and electrical housing
Problem Phenomenon
【Problem Phenomenon】Electronic and electrical housings need impact resistance, flame retardancy and dimensional stability
Cause Analysis
PC has high impact resistance, complete flame retardant grades and dimensional stability, widely used in chargers, connectors and housings; flame retardancy reaches UL94 V-0；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
Electronic housings select flame retardant PC; thin-walled parts high-flow grades; CTI according to voltage level；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability；Change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
PC electronic housings impact resistant and flame retardant, mainstay of connectors and chargers；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
