Reworkable Edgebond Adhesives

Ruggedize and raise board level reliability

Edgebond adhesives, sometimes referred to as Corner Glues or Cornerbond Adhesives, are an excellent alternative to board-level underfills. Process cost is reduced by the elimination of board preheat and capillary flow. Quality is improved because voids and incompatibility with flux residues are moot. Rework is far easier and performed with higher yield.

Zymet's reworkable edgebond adhesives enhance board level reliability and ruggedize 3D and 2.5D packages, FO-WLP's, WLCSP's, BGA's, CSP's and QFN's. They are used in high performance (HPC), enterprise, automotive, aerospace and consumer applications.


  • High Tg and Low CTE for the most challenging assemblies and applications
  • Fast, in-line curing with cure time as short as 1 minute
  • Moderate temperature cure
