Electrical flexible circuit board

摘要

The circuit board has two carrier layers of polyamide material 1,2 and both outer surfaces are copper layers. At specific locations through hole connections 4 are formed .Electrical connections can be formed at these points with the use of solder pads 8. Located between the carrier layers is a heating conductor 9 that has a ring shape around a solder pad region. When the conductor is heated the solder pad melts to make the connection.
