发明名称 Printed circiuit board
摘要 A printed circuit board has temperature-stable electric components, such as resistance networks, disposed on the soldering side of the circuit board. The components mounted on the soldering side of the board are mounted as a unit containing the network, which unit has a recess which partially surrounds the solder connection location of the circuit board, at which point the unitary component is electrically and mechanically connected to the board. The recesses are beveled to facilitate solder flow, and cover approximately half of the connection location of the circuit board.
