USG137 is a snap-cure epoxy adhesive for underfilling or encapsulating chip-on-board, bare die, BGA, flip-chip, CSP, and other electronic applications. It is a one-part, capillary flow formulation that cures at elevated temperature in short time to provide strong bonding to silicon, flip chip, BGA, ceramics, FR4, LTCC, aluminum, copper, stainless steel, etc. with minimized thermal mismatching stress. It has a long pot life at room temperature for easy storage and shipping. USG137 is dispensable. For underfilling, it is recommended to warm the applied surface to ~ 85°C to promote faster capillary flow.

The adhesive is a pre-mixed adhesive as one part for easier applying. In order to keep longer usage life, please always store the original or left material in refrigerator (< 4°C). For some applications, it is recommended to warm the applied surface to ~ 85°C, and/or the adhesive to about 50°C, to promote faster capillary flow.
We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive processing instructions can be obtained by contacting directly to USGlue.com.
USG137 has a shelf life of at least 6 months when stored in refrigerator (-40°C) in the originally sealed container. The 'Best use before end' date of each batch appears on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
General hygiene regulations should be observed. Comprehensive instructions are given in the corresponding Material Safety Data Sheets. They are available on request from USGlue.com.
