Method for manufacturing electronic module integrated in electronic control unit of vehicle, involves soldering electronic components to pad, and forming solder coating on contact surface for spring in same operation by heating board

摘要

The method involves electrically connecting peripheral element such as a sensor or an actuator by a metal spring having contact surface (18) on the printed circuit board (12). A solder is partially applied to the pad (40) and the contact surface. One side (14,22) of the printed circuit board is loaded with the electronic components (24). The components are soldered to the pad. The convex solder coating (20) is partially formed on the contact surface for metal spring in the same operation by heating the printed circuit board. A tin-containing solder as a solder paste is used. An independent claim is included for electronic module.
