Abstract
Abstract 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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
116 words
A temperature-stable component for mounting on a printed circuit board having a plurality of solder-clad holes therein, said holes being selectively interconnected by printed conductor paths on said circuit board, said temperature-stable component comprising a support plate having longitudinal sides with a plurality of recesses therein for partially surrounding said solder-clad holes in said circuit board for electrical and mechanical connection thereto by soldering, each said recess having a lateral edge disposed parallel to said longitudinal sides, said lateral edge being beveled with respect to a surface of said support plate and further being coated with a metal layer having a good electrical conductivity extending from said lateral edge to said surface of said support plate.
Claim 2
Dependent Claim
116 words
