FAQ
Q1: What is the curing recommendation?
A: Cures at 150C for 30 minutes or as per SMT oven profile. Warm-up time should be factored in for actual process settings.
Q2: Can the adhesive be printed using stencils?
A: Yes. Its thixotropic index and stability ensure clean stencil printing and dot retention.
Q3: Is it safe to leave the adhesive exposed to air during operation?
A: It resists moisture pickup, but prolonged exposure may affect print quality. It should be cured promptly after printing.
Q4: What substrates is it compatible with?
A: Standard FR4 PCBs and SMT-grade component surfaces. It shows no corrosion on bronze mirror surfaces.
Q5: How should it be stored and handled?
A: Store at 28C. Before use, bring to ambient temperature (e.g., 30 mL cartridges: 24 hours; 200300 mL: 46 hours). Avoid moisture ingress and never return unused glue to the original container.
Exceptional Adhesion & Thermal Stability6103 SMT Red Glue offers unparalleled bonding strength for FR-4 PCBs and various electronic component surfaces such as ceramic, plastic, and metal. Its thermal stability allows it to maintain adhesion and performance even through extreme solder reflow conditions at 260C, making it a dependable choice for demanding electronic assembly lines.
Precision Dispensing with Stable ViscosityEngineered for both automated dispensing and stencil printing, this adhesive maintains stable viscosity throughout its shelf life. This ensures accurate and consistent application, reduces waste, and improves overall process reliability in high-speed manufacturing workflows.
Reliable Performance in Humid EnvironmentsWith very low hygroscopicity, 6103 SMT Red Glue resists moisture absorption, preserving adhesive integrity in high-humidity settings. This trait guarantees lasting bond strength and dielectric protection for sensitive electronic components exposed to variable environmental conditions.
FAQs of SMT Red Glue -6103:
Q: How should 6103 SMT Red Glue be applied for optimal results in electronic assembly?
A: 6103 SMT Red Glue is best dispensed using precise equipment or stencil printing techniques onto FR-4 PCBs and component terminations. Ensure the targeted areas are clean and apply the adhesive in a uniform 6 mm thickness for secure positioning before the solder reflow process.
Q: What makes 6103 SMT Red Glue suitable for high-speed surface-mount production processes?
A: Its rapid heat-curing formulation, stable viscosity, and excellent adhesion to electronic materials make 6103 ideal for automated application and fast cycle times necessary in modern surface-mount manufacturing environments.
Q: When and how does 6103 SMT Red Glue develop its full bonding strength?
A: The adhesive develops optimal bond strength after heat curing at 150C for 30 minutes, providing high shear and tensile strength to securely hold components before soldering and throughout the assembly lifecycle.
Q: Where can this adhesive be safely used without risk of metallurgical corrosion?
A: 6103 SMT Red Glue is safe for direct application on PCB copper pads, bronze mirror metallurgy, FR-4 PCB substrates, ceramic, plastic, metal component terminations, and SMD capacitor or resistor ends, as it does not induce corrosion or degrade sensitive circuit materials.
Q: What benefits does the glue offer in humid manufacturing environments?
A: Its very low hygroscopicity ensures that moisture absorption is minimized, preserving adhesive consistency, dielectric protection, and mechanical strength, even under humid conditions prevalent in some manufacturing and assembly areas.
Q: How long can the adhesive be stored, and under what conditions?
A: 6103 SMT Red Glue has a shelf life of 6 months. It should be stored at or below 150C as specified, ensuring that the product retains its viscosity and performance attributes throughout its lifespan.
