PVB Assembly Environment
Problem Phenomenon
PVB assembly environment cleanliness is insufficient, dust and impurities are trapped, optical defects.
Cause Analysis
PVB assembly needs a clean environment; dust and impurities; static electricity adsorption; personnel operation; environmental monitoring.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solution
①Cleanroom environment control; ②Static electricity elimination; ③Operation specification training; ④Environmental monitoring records.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Key Takeaway
PVB assembly cleanliness is optical quality assurance; static electricity management is a detail; specification execution prevents contamination.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
