IPC 3406

The IPC-3406 covers guidelines for selecting electrically conductive adhesives for use in assembly of components to printed circuit boards 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. Both major types of adhesives, isotropic (conducting equally in all directions) and anisotropic (unidirectional conductivity) are covered. The two major divisions of polymer adhesives, thermosets and thermoplastics are described.
