Q1:What is a Rigid-Flex PCB?
A1: A Rigid-Flex PCB is a hybrid board that consists of a combination
of rigid and flexible printed circuit boards. These boards are
designed by combining flexible circuit boards with one or more
rigid boards.
The flexible part of the board is usually used for providing
interconnections between rigid boards, which allows narrow
conductor lines which take up less space making the boards smaller.
Using flexible PCBs for interconnections also eliminates the need
for connectors, which are bulky and heavy making rigid-flex printed
circuit boards much lighter. Interconnections using flexible PCBs
over connectors also provide lower losses and accommodate
controlled impedance and eliminate connection problems such as cold
joints.
Another major advantage of Rigid-Flex boards is the use of
different substrate materials in different sections on the board.
Some sections of the board might require high performance
substrates which are expensive while others sections might not
could use a standard FR-4 substrate. This flexibility in terms of
substrate selection can optimize the performance and cost of
Rigid-Flex PCBs.
Designers often use Rigid-Flex PCBs as they provide a lot of design
flexibility. These boards are also more cost effective than
flexible PCB boards.
