Leadless chip carrier compatible printed wiring boards
Abstract
The advantages gained by reduced space and diminished weight through the use of leadless chip carriers (LCCs) have been negated by the low reliability of the LCC/printed wiring board (PWB) interconnections. This paper addresses the cause of the solder joint failure and work being done to reduce it. Both material studies and test methods are discussed. Future trends and expected results indicate that reliable electronic systems with leadless chip carriers 1-1/2 to 2 inches square can be produced.
