Proper adhesives and encapsulants are a key part of integrating chip level components to the PCB. Many factors must be considered like adhesion to all the substrates, the right rheology and stress imparted to the chips and wire bonds.

Polymark has materials for bonding the die and insuring either the electrical isolation or conductivity, encapsulating or globbing over a die, potting of the chip area and final lid sealing.



At Polymark, we can select from our assortment of chemistries to customize a solution for you. From enhanced thermal or electrical conductivity, special rheological concerns, curing options, and expansion issues, we will find the right solution to your need.
