发明名称 Circuit board stiffener
摘要 A board stiffener (50) of rigid construction of high heat resistance material having recesses (62) to be secured to a large circuit board (10) over a plurality of electrical articles having contacts (24) soldered to the board, such as electrical connectors (20). The board stiffener (50) is mounted firmly to the board at locations near each recess (62) in abutment with top surfaces (34) of connectors (20) and provides resistance against warping by the board (10) during high temperature soldering operations. The board stiffener (50) can have channels (68,70) along the bottom surface (52) and the recess surfaces (72,74) to enable flow of solvent during flux cleaning following soldering operations.
