Many beginners do not know how to start learning hardware circuits. In fact, the "hardware circuit" is composed of a part of the "unit module circuit". The so-called "unit module circuit" includes: various regulated power supply circuits (like the LM

Flex Circuits - Bend proximity spec

Electronics Forum | Mon Aug 02 08:11:25 EDT 2010 | muarty

Is there a specification in relation to the proximity to features that a Flex circuit should or should not be bent? I am experiencing broken tracks on some flexible circuits which appear to be getting 'flexed' directly adjacent to a soldered joint in
