The RIGID-FLEX circuit is a hybrid product that combines 2 types of technologies: rigid circuits and Flex circuits.
The manufacturing process requires good experience on som key steps:
. The milling process
. The electrical test
. The pressing of the layers
Few manufacturers of printed circuits to master this technology. However, it has many advantages in terms of size and reliability. It is used in many fields of applications such as medical, aeronautics, automotive.
Main advantages of Rigid-Flex:
. Reliability: elimination of inter-card connectivity, which represents the most significant source of defaults in electronics.
. Space saving: elimination of inter-card connectors, with fewer solder points.
. Gain on weight.
. Cost reduction: elimination of connectors and inter-card cables.
. Improved signal transmission through homogenization of the conductors.
. Save time: assembly already done
