SMT Red Glue
SMT Red Glue
SMT red glue is a single-component epoxy adhesive primarily used during the surface-mount assembly process to temporarily secure components to a PCB before soldering. Its strong initial bonding and fast-curing behavior under heat make it essential for double-sided SMT manufacturing, where components on the underside must remain fixed during reflow.
But beyond assembly support, this type of adhesive also serves a secondary function as a protective material — used to cover or encapsulate sensitive chips to help prevent tampering or reverse engineering, making it useful for IP protection.
Key Features & Benefits:
- 🧲 Strong Adhesion to PCB and SMDs
Quickly bonds a wide range of surface-mount components to FR-4 and other PCB substrates. -
🔥 Fast Curing at Elevated Temperatures
Typically cures within seconds to minutes at high temperatures (~120–150°C), ideal for high-speed production lines. -
🧼 Clean Application
Non-corrosive and stable, ensuring minimal impact on surrounding components or solder joints. -
⚙️ Mechanical Stability During Reflow
Holds components firmly in place during wave soldering or reflow processes — essential for double-sided boards. -
🔐 Encapsulation & IP Protection
Can be used to cover ICs or critical areas of the PCB, obscuring proprietary chip designs and making unauthorized access difficult. -
🌱 RoHS and REACH Compliant
Safe for use in environmentally regulated production environments.
Common Applications:
- SMT Assembly for Double-Sided PCBs
- Consumer Electronics
- Automotive Electronics
- Networking & Telecom Equipment
- IP Protection in Sensitive Devices
Choose SMT red glue when you need a reliable, fast-curing adhesive to hold surface-mounted devices in place during PCB assembly, particularly in double-sided reflow processes. It’s also an ideal solution for manufacturers looking to add a layer of physical protection to intellectual property, helping reduce the risk of tampering or reverse engineering.
