scope:

This document covers guidelines for selecting electrically conductive adhesives for use in assembly of components to printed circuit boards (PCB) or similar wiring interconnect systems. The focus is on the use of adhesives as solder alternatives. The process discussion attempts to stay within the bounds of the existing solder assembly infrastructure as much as possible. Both major types of adhesives, isotropic (conducting equally in all directions) and anisotropic (uni-directional conductivity), are covered. The two major divi- sions of polymer adhesives, thermosets and thermoplastics, are described.
