Structure of FPC
According to the number of layers of conductive copper foil, FPC can be divided into single
Layer circuit, double layer circuit, multi-layer circuit, double sided and so on.
Single-layer structure: the flexible circuit of this structure is the simplest structure of the
Flexible PCB. Usually the base material (dielectric substrates) + transparent rubber(adhesive)
+ copper foil is a set of purchased raw materials(semi-manufactures), the protective film
and transparent glue are another kind of bought raw material. First, copper foil must be
Etched to obtain the required circuit, and the protective film should be drilled to reveal the
Corresponding pad. after cleaning, the two are combined by rolling. Then the exposed part
of the pad electroplated gold or tin to protect. In this way, the big panel board will be ready.
Generally also it's stamped into the corresponding shape of the small circuit board. There is
Also no protective film directly on the copper foil, but printed resistance soldering coating, so
that the cost will be lower, but the mechanical strength of the circuit board will become worse.
unless the strength requirement is not high and the price needs to be as low as possible, it is
Best to apply the protective film method.
Double layer structure: when the circuit is too complex to be wired, or copper foil is needed
to shield the ground, it is necessary to choose a double layer or even a multilayer. the most
Typical difference between a multilayer and a single plate is the addition of a perforated structure
to connect the layers of copper foil. the first process of transparent rubber + base material +
Copper foil is to make holes. Drill holes in the base material and copper foil first, clean and then
Plated with a certain thickness of copper. the subsequent fabrication process is almost the same
as the single-layer circuit.
Double sided structure: both sides of the double sided FPC have pads, mainly used to connect
Other circuit boards. Although it and monolayer structure is similar, but the manufacturing
Process is very different. Its raw material is copper foil, protective film and transparent glue.
the protective film should be drilled according to the position of the pad first, then the copper
Foil should be affixed, the pad and track lines should be etched and then the protective film of
Another drilled hole should be affixed.
