Q

Uneven thickness of EVA film extrusion

A

The key points of EVA film thickness control are similar to those of PE film; die lip precision and temperature uniformity are the core.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post EVA; film; thickness; die lip; die temperature; thickness measurement

Q

Excessively long EVA photovoltaic lamination time

A

Longer lamination time is not better; following the material supplier's process window is a basic principle.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post EVA; photovoltaic; lamination time; peroxide; bubbles; process window

Q

Uneven EVA photovoltaic lamination temperature

A

Lamination temperature uniformity directly affects module consistency; high-temperature cloth is a simple and effective temperature equalization means.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post EVA; photovoltaic; lamination; temperature unevenness; high-temperature cloth; heating plate

Q

EVA Hot Melt Adhesive Unstable Viscosity

A

Hot melt adhesive application quality is guaranteed by temperature stability; oxidation management extends the service life of the adhesive.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post EVA; hot melt adhesive; viscosity; temperature; oxidation; glue tank

Q

EVA Film High Shrinkage Rate

A

Film shrinkage affects module reliability; low-shrinkage material plus process matching is the solution.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post EVA; film; shrinkage; cells; lamination; batch

Q

EVA Film Insufficient Crosslinking Degree

A

The crosslinking degree is the core indicator of film quality; the lamination process window and material freshness are both indispensable.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post EVA; film; crosslinking degree; lamination; storage; inspection

Q

EVA Photovoltaic Busbar Bending

A

Busbar bending is a coupling problem of exhaust and material fluidity; vacuum time and lamination pressure are the main adjustment parameters.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post EVA; photovoltaic; busbar; bending; lamination; exhaust

Q

EVA Photovoltaic Module Broken Cells

A

Broken cells are a typical problem of the superposition of human factors and process; soldering quality and operation specifications are the focus of prevention and control.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post EVA; photovoltaic; broken cells; cells; lamination; soldering

Q

COC Extrusion Process

A

The stability and uniformity of COC extrusion are the quality basis; equal emphasis on temperature and cooling; management ensures consistency.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post COC; extrusion; film; melt stability; thickness; cooling

Q

COC 3D Printing and Injection Molded Parts Mixed Use Failure

A

The process consistency of COC parts affects system reliability; qualified individual parts do not mean a qualified system; the verification level must match the failure mode level.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post COC; assembly; process difference; system verification; fit; failure
