Clarifications
of FPC
According
to the combination of base material and copper foil, flexible circuit board can
be divided into two types: flexible board with adhesive and flexible board
without adhesive. The price of non-adhesive flexible PCB is much higher than that
of adhesive flexible PCB, but its flexibility, bonding force between copper
foil and substrate and flatness of solder are also better than that of adhesive
flexible PCB. So it is only used in the high demand situations, such as the: COF (CHIP ON FLEX, flexible board with bare chip, the high flatness of the pad)
and so on. Because its price is high, most of the flexible PCBs used in the
market are still adhesive flexible circuit board. Because the flexible circuit
board is mainly used in the situation where bending is required, if the design
or process is not reasonable, it is easy to produce micro-cracks, welding and
other defects.
Economy
of using FPC
If
the circuit design is relatively simple, the total volume is small, and the
space is suitable, the traditional internal connection is much cheaper.
Flexible circuits are a good design option if the circuit is complex, processes
many signals or has special electrical or mechanical requirements. When the
size and performance of applications exceed the capacity of rigid circuits, flexible assembly is the most economical. A 12mil pad with a 5mil through hole
and a flexible circuit with 3mil lines and spacing can be fabricated on a thin
film. Therefore, it is more reliable to mount the chip directly on the film.
There is no flame retardant that could be an ion source. These films may be
protective and solidified at higher temperatures to obtain higher glass
transition temperatures. Flexible materials are less costly than rigid
materials because they are free of connectors.
