Temperature required to disassemble huawei Y9 2019

🔥 Recommended Temperature Guidelines

• Removing the Back Cover (Adhesive-Plastic Cover):
• The ideal surface temperature range is between 60°C and 80°C (140°F and 176°F).
• Apply heat uniformly around the edges for one to two minutes using a hair dryer or heat gun.
• Front Screen (in the event that an LCD or digitizer is being replaced):
• The optimal temperature range is between 70°C and 90°C (158°F and 194°F).
• Heat should be directed away from the center and toward the screen's edges.

⚠️ Important Tips:

• Set a hair dryer or heat gun with a temperature control to medium.
• To prevent melting plastic or harming the display/FPC connectors, do not raise the temperature above 100°C (212°F).
• If a thermal camera or laser thermometer is available, use it to keep an eye on the temperature.
• Always work on a spotless, static-free surface and wear anti-static gloves.
