PCABS Surface Treatment Process
Problem Phenomenon
[Problem Phenomenon] PC/ABS requires surface decoration such as spraying, electroplating, and IMD
Cause Analysis
PC/ABS surface is suitable for various decorations such as spraying, electroplating, IMD, and heat transfer; different processes have different requirements for the substrate; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Select the substrate grade according to the decoration process; clean before spraying; select electroplating grade for electroplating; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
PC/ABS has a full set of surface processes, with substrate grades selected accordingly; 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
