  • Soldering external leads to film circuits
    Patent number: H54
    Abstract: Disclosed is a method of soldering external leads to film circuits formed on insulating substrates. The leads, usually in the form of lead frames, are clipped onto the substrates and a flux is applied. The assemblies are then immersed into molten solder. As they are withdrawn from the solder, they pass through high-pressure hot gas jets which remove the excess solder.
