OCA vs SCA Bonding: Which Is Better for Your LCD Production Line?
In LCD and OLED production, OCA bonding and SCA bonding are 2 mainstream innovations used to affix glass, touch panels, and present components. Lots of suppliers and refurbishing manufacturing facilities struggle to determine which bonding method is better for their line of product.
As an expert OCA bonding machine and SCA bonding machine factory, we have over one decade of sector experience and have sustained thousands of worldwide consumers. This short article compares OCA bonding vs SCA bonding from a sensible and technological perspective to aid you choose the right service.
1. What Is OCA Bonding?
OCA bonding uses "Optically Clear Adhesive" movie to connect LCD module layers.
Qualities of OCA bonding:
Makes use of completely dry adhesive movie
Needs precise positioning
Commonly paired with an OCA vacuum laminating machine
Usual in cellphone, tablet, and industrial screen repair
Offers excellent stability and optical clearness
Because OCA film is pre-cut and very easy to shop, several LCD reconditioning companies like OCA bonding for high-efficiency process.

2. What Is SCA Bonding?
SCA bonding utilizes silicone-based fluid adhesive (Silicone Clear Adhesive).
Key characteristics:
Fluid adhesive with flexible density
Spread evenly throughout bonding
Suitable for rounded screens and large display screens
Deals solid influence resistance
Excellent optical efficiency
SCA bonding is widely used in automobile displays, commercial screens, ruggedized displays, and premium consumer electronic devices.
3. OCA Bonding vs SCA Bonding: Key Differences
3.1 Material Form
| Aspect | OCA Bonding | SCA Bonding |
|---|---|---|
