The OCA bubble remover machine plays a crucial role in mobile phone and tablet screen repair by eliminating bubbles during the laminating process. Despite its importance, users often encounter troubleshooting issues that hamper performance. This article will explore common problems such as incomplete bubble removal, bubbles rebounding, edge bubbles, delayed bubbles, leaks, and pressure issues. Readers will gain practical know-how to address these challenges efficiently, with a focus on the TBK-808A all-in-one OCA machine as a reliable solution.

Common Bubble Removal Problems

Incomplete Bubble Removal

When bubbles are not completely removed, it often stems from improper temperature, pressure, or timing settings. Inadequate pressure may fail to push out all bubbles, while incorrect temperature can affect the adhesion properties of the OCA film.

Bubbles Rebounding

Bubbles that reappear after removal suggest that pressure was insufficient or inconsistent. This is typically linked to machine calibration errors, pump malfunction, or leaks in the vacuum chamber.

Bubbles on the Edge

Bubbles persisting at the screen edges are common and can result from uneven pressure distribution or poor alignment of the screen and the OCA film during the process.

Delayed Bubble Formation

Delayed bubbles may appear after some hours or days post-lamination, caused by trapped microbubbles or temperature fluctuations during the curing process.

Fixing Leakage and Pressure Issues

Leaks in the Bubble Removing Machine

Leaks reduce the vacuum effectiveness, causing bubbles to remain or rebound. Identifying leaks involves inspecting seals, tubing, and connections. Repairing or replacing damaged parts restores suction integrity.

Pressure Does Not Increase

If the pressure in the bubble remover does not go up, it could be due to pump failure, clogged filters, or faulty pressure sensors. Regular maintenance is essential to prevent this, and troubleshooting should start with sensor recalibration and pump functionality checks.
