How to Improve Yield Rate in the OCA Bonding Process
The OCA bonding procedure is among the most essential steps in LCD and OLED component repair or production. Whether you run a smart device repair facility or an industrial screen assembly line, the bonding return price directly impacts production expense, performance, and client fulfillment.
As an expert OCA bonding machine factory and worldwide supplier, we have offered hundreds of clients worldwide over the past decade. Based upon our useful experience in the OCA bonding procedure, this overview sums up the most efficient methods to boost yield price and lower bonding defects.
1. Understand one of the most Usual OCA Bonding Issues
Prior to boosting the yield price, you must know what problems usually occur throughout the OCA bonding process. One of the most regular issues include:
1.1 Air bubbles
Edge bubbles
Center bubbles
Micro-bubbles after pushing
1.2 Light leakage
Usually caused by uneven stress or incorrect mold size.
1.3 Imbalance
Usually as a result of incorrect placement systems or unpredictable fixtures.
1.4 Dust contamination
One single dust particle can trigger a defective product.
Comprehending these concerns permits you to optimize the OCA bonding procedure and readjust your OCA bonding machine appropriately.
2. Enhance Return Rate Through Controlled Environment
2.1 Maintain a clean working environment
Dirt is the number one adversary of the OCA bonding procedure.
To enhance return rate:
Keep humidity in between 45-- 55%.
Usage anti-static workstations.
Mount air filtration or FFU systems.
Tidy mold and mildews and components prior to each set.
2.2 Optimize temperature.
Both OCA product and LCD displays execute ideal within 22-- 25 ° C.
A stable atmosphere minimizes glue shrinking and air movement, raising bonding success.
3. Select High-Quality OCA Film and LCD Products.
The quality of OCA movie straight affects the bonding result.
3.1 Needs for OCA film.
Steady viscosity.
Good transparency.
No bending.
Constant density.
3.2 Product compatibility.
Different LCD modules need different bonding criteria. Using the wrong OCA can cause bubbles or optical issues.
As a knowledgeable OCA bonding machine supplier, we assist clients choose the proper OCA movie to match their components.
4. Enhance OCA Bonding Machine Parameters.
The OCA bonding machine plays a crucial role in identifying yield price. Proper specification setups boost uniformity and reduce rework.
4.1 Calibrate positioning system.
Make sure:.
CCD electronic camera precision.
Secure alignment components.
Correct mold and mildew dimension.
Even a minor misalignment can reduce return considerably.
4.2 Change vacuum pressure.
Vacuum cleaner gets rid of residual air.
Too high → LCD contortion.
Also low → Staying bubbles.
4.3 Maximize laminating stress.
Different displays require different pressure degrees to stay clear of:.
Light leakage.
Local bubbles.
Panel damage.
Our OCA bonding machines allow accurate personalization of criteria to match each OCA bonding process.
5. Systematize the OCA Bonding Refine Process.
Constant procedures enhance success price.
5.1 Standard OCA bonding workflow.
Tidy LCD and glass extensively.
Eliminate protective films.
Straighten LCD with OCA movie.
Place into OCA bonding machine.
Apply vacuum cleaner lamination.
Transfer to bubble cleaner for last baking.
5.2 Train operators.
Inappropriate handling often creates:.
Dirt.
Fingerprints.
Skewed placement.
We offer complimentary training videos and operation handbooks for global clients.
6. Utilize a High-Quality Bubble Cleaner Equipment.
Despite having ideal lamination, small bubbles can still show up.
A stable OCA bubble eliminator machine makes certain:.
Uniform warm.
Consistent pressure.
Reduced contortion.
Dependable final results.
Our bubble cleaner units are adjusted to function perfectly with our OCA bonding devices, even more improving return rate.
