Abstract
Hybrid circuits are usually secured with contact pins (combs) on printed circuit boards by undergoing a flow solder bath. Further, surface-mountable components are soldered on the printed circuit board in a furnace. Two soldering processes are necessary for this purpose. The method of the invention avoids one of the soldering processes by applying through-contacted bores on the carrier substrate of the hybrid circuit. These through-contacted bores are put in place onto solder surfaces of the printed circuit board having a paste solder and the overall arrangement is soldered in a furnace.
