Zymet UA-3307-B Edgebond Adhesive for Automotive Board Level Reliability

At APEX Expo 2018, Zymet will be featuring its recently introduced edgebond adhesive, UA-3307-B, for enhancing board level reliability in automotive and other harsh environment applications. BGA’s and WLCSP’s whose corners and edges are bonded with this adhesive have passed more than 2000 cycles of -40°C to 125°C thermal cycling without failure. Large WLCSP’s, exceeding 8-mm in size, have passed more than 1500 cycles.

The benefits of using Zymet’s edgebond adhesive, rather than introducing an underfill under the component, are significant. Board preheat and dwell time are not needed for underfill flow. There is no risk of underfill voids caused by flux residues impeding flow. And, there is no risk of underfill/flux-residue chemical incompatibility affecting underfill cure. Use of Zymet’s UA-3307-B is simple, repeatable, and reliable.
