Characteristics
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.

Special Features and Benefits
• Fast snap cure
• Long pot life at room temperature
• Easy flow and capillary flow
• High thermal stability
• High structural bonding strength
• Low bleeding, low volatile
• Low ionic content

Typical Applications
• Aerospace electronics
• Automotive electronics
• Semiconductor and Telecommunications
• Bonding of die to LTCC, Al, Cu
• Underfilling of BGA, Bare die, flip-chip, CSP
• Chip-on-board bonding / encapsulating

Processing Instruction

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.

Safety information
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.

The data presented in this leaflet are in accordance with the present state of our knowledge, but do not absolve the user from carefully checking all supplies immediately on receipt.
