HT-130S Surface Mount Adhesive Solution
HT-130S is a one-component, intermediate-temperature, fast heat-curable surface mount adhesive engineered for high-speed dispensing and screen printing applications. Manufactured by MacDermid Alpha, this epoxy-based red paste provides exceptional productivity in wave-soldering processes. Electronics manufacturers select HT-130S for securing surface-mount components precisely on printed circuit board (PCB) assemblies prior to wave soldering.
Key Features and Benefits of HT-130S
This high-performance surface mount adhesive delivers a balanced set of processing and mechanical properties tailored for modern SMT manufacturing lines:
- Fast Heat Curing: Rapidly cures at intermediate temperatures, such as 80 seconds at 150 °C in a convection oven.
- Excellent Thermal Resistance: Maintains high bond strength and structural integrity during wave soldering thermal spikes.
- Non-Sagging Profile: Features a high thixotropic index (≥ 4.0) to maintain crisp dot profiles and prevent slumping.
- High Electrical Insulation: Delivers superior insulation resistance (≥ 1 x 10¹² Ω) and zero corrosion after extended humidity testing.
- Low Moisture Absorption: Keeps moisture absorption under ≤ 1.0 wt% after 24 hours immersion at 40 °C to preserve circuit performance.
Processing Guidelines and Curing Conditions
Applying HT-130S on assembly lines enables operators to achieve consistent dot geometry and high production speeds. Uncured, this red paste exhibits a viscosity of 500 to 600 Poise (Malcom PC-10A, 30 rpm @ 25 °C), a pot life of 7 days at 25 °C, and a shelf life of 6 months when stored between 1 and 10 °C. Recommended cure conditions in a convection oven require a profile of 80 seconds at 150 °C, though optimal conditions may vary based on equipment and substrate mass.
