Abstract

A printed circuit board 1 is soldered to a flexible copper-etched circuit tail 2 for making electrical connections to the tail 2 from board 1. Board 1 is a heat shield and a soldering mask to permit flow of solder onto conductors 4 of tail 2, without damage to the flexible circuit substrate 5 composed of material such as MYLAR* or KAPTON* - H film plastic. A portion of tail 2 is solder plated. Board 1 with plated through holes is solder plated. Board 1 and tail 2 are arranged as shown so that each etched circuit line 4 lies directly beneath a hole 3. By reflow soldering, tail 2 and board 1 are electrically joined as at 6. An infrared lamp or hot gas (nitrogen) is the heat source. Plated through holes are used to view specific areas to be soldered directly and as alignment targets.
