ALPHA HT-130DM

Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium

ALPHA HT-130DM

Main features

  • Non-Sag High-Speed Dispensing
  • Fast 80-Second Heat Cure
  • High-Resistance Electrical Insulation

Product Description

ALPHA HiTech HT-130DM SMD Adhesive is a one-part, red epoxy paste for heat-cured attachment of surface-mount components in electronics assembly. It is formulated for high-speed dispensing and screen printing, with non-sag behavior and a thixotropic index above 4.0. A typical seven-day pot life at 25 deg C provides an extended working window, while a representative convection-oven cure is 80 seconds at 150 deg C. After cure, the material has 80 to 90 Shore D hardness and a glass transition temperature of at least 100 deg C. The adhesive is used for surface-mount component attachment in assembly processes that include wave soldering.

Key Features

  • Controlled deposition: Non-sag epoxy paste supports high-speed dispensing and screen printing.
  • Fast heat cure: Representative convection-oven cure is 80 seconds at 150 deg C; actual cure depends on equipment and assembly conditions.
  • Electrical insulation: Cured insulation resistance is at least 1 x 10^12 ohm after 95 hours at 40 deg C and 95% RH.

Applications

Heat-cured attachment of surface-mount components in electronics assembly, including processes with wave soldering.

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
