- Five Costly Repair Mistakes to Avoid Common errors include prying too deep and damaging backlight layers, using regular adhesive instead of professional OCA, leaving residual glue that causes screen warping, skipping ESD protection and damaging ITO circuits, and skipping charging interference testing before delivery. These mistakes can push scrap rates up to 15–20%.
- Standardized Correct Operation Procedures Follow these best practices: heat evenly at controlled temperature before disassembly, use only certified OCA adhesive or pre-laminated assemblies, thoroughly clean all residual frame adhesive, wear ESD wrist straps throughout the process, and run full function tests including charging ghost-touch check before returning to customers.
- Quality Parts Simplify Proper Repair ZSDScreen pre-laminated capacitive touch LCD assemblies come with factory-applied OCA and built-in ESD protection, eliminating manual gluing errors and reducing electrostatic damage risks. Each unit is pre-tested for touch uniformity and anti-interference performance, helping technicians achieve consistent first-pass success and lower scrap rates.
