EMS CA-195 is approximately half the cost of a pure silver filled die attach adhesive, has a high glass transition temperature (Tg) to facilitate wire bonding small die, low extractable ionics and high adhesion to silver and copper lead frames. CA-195 has a dispense open time greater than 24 hours (measured as a 25 percent increase in viscosity), while maintaining optimized rheology for pin transfer or needle dispensing. 

The adhesive is ideal for small die thermal management applications. CA-195 is the latest addition to Engineered Material Systems’ extensive line of electronic materials for semiconductor, circuit assembly, photovoltaic, printer head, camera module, disk drive and photonic applications.
