1. LCM and CG yield of incoming or self supplied materials, including but not limited to appearance and function yield. Only high-quality LCM and CG yield, can have high-quality lamination yield.

2. Appropriate lamination technology. For different laminating materials, choosing the right laminating scheme is also one of the keys to improve the yield.

3. Proficiency of employees. For the same full fit product, the higher the employee's proficiency, the higher the fit yield.

4. Pass rate of inspection. The improvement of fitting yield is also inseparable from the quality assurance of inspectors.
