Single-sided flex PCBs

Single-sided flex PCBs

Single-sided flexible circuits have a single conductor layer made of either a metal or conductive (metal filled) polymer on a flexible dielectric film. Holes may be formed in the base film to allow component leads to pass through for interconnection, normally by soldering. Single sided flex circuits can be fabricated with or without such protective coatings as cover layers or cover coats, however the use of a protective coating over circuits is the most common practice.

One conductive layer, either bonded between two insulating layers or uncovered on one side.

Access holes to conductors may be on either one or both sides.
