November 4, 2026 ALPHA HiTech SM42-120P Surface Mount Adhesive
ALPHA HiTech SM42-120P is a high-performance one-component fast curable surface mount adhesive designed specifically for screen printing and dispensing applications in SMT assembly lines. Manufactured by MacDermid Alpha, this advanced formulation ensures reliable component holding before wave soldering.
Key Features and Engineering Benefits
Engineered for high-speed automated electronics assembly, this surface mount adhesive provides outstanding process stability and thermal resistance:
- Excellent thermal resistance capable of withstanding harsh soldering heat profiles.
- High adhesion strength, keeping surface-mount components securely anchored to the PCB.
- Excellent workability with a non-sagging profile that prevents dot slumping during high-speed placement.
- Fully halogen-free formulation supporting sustainable microelectronic packaging.
- Complies strictly with global RoHS Directive EU/2015/863 environmental standards.
Application Guidelines and Thermal Curing
Adhering to proper storage, thawing, and thermal curing protocols ensures optimal dot height consistency and adhesion performance:
- Storage & Thawing: Store at 1°C to 10°C in an upright position (tip facing bottom) to maintain product stability. Remove syringe from the refrigerator and set aside at room temperature for 2 hours to thaw completely before opening the cap.
- Dispensing & Printing: Effectively screen-printed or dispensed under standard room temperature conditions. Never return unused material to its original container to prevent contamination.
- Curing Profiles (Convection Oven): Achieve full property development by curing at 120°C for a minimum of 120 seconds, or at 150°C for a minimum of 80 seconds.
