Abstract
Improvement in the adhesion between an Alloy 42 (Ni/Fe alloy) lead fra me and epoxy molding compounds for IC packages was studied by (i) addi ng modifiers to the epoxy molding compounds; (ii) using various phenol resins as curing agents; and (iii) changing the Alloy 42 die pad surf ace to Al, SiO, SiO2 or Si3N4. Good improvement was obtained in all th ree cases. When the lead frame surface was changed to Al, SiO, SiO2 or Si3N4, almost complete adhesion was observed, even after moisture-abs orbed IC packages were dipped in the solder.
