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.
