EVA adhesive film cutting precision
Problem Phenomenon
Cutting dimension deviation of the adhesive film affects module encapsulation.
Cause Analysis
Manual cutting has large errors; the extensibility of the film makes dimension control difficult.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone; this mechanism has been repeatedly verified by industry information, and should be confirmed first during troubleshooting
Solution
①Adopt automatic cutting equipment; ②control the cutting environment tension; ③optimize the layout according to module dimensions; ④sample-check the cutting dimensions.; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Cutting precision affects the edge quality of the module; automation is the direction of improvement.; after confirming effectiveness, fix 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
