Flex and rigid flex boards.
Flex circuit design rules.
Applications which go beyond our standard design rules require technical clarification with our product management.
Tolerance setting flex circuit designs proper application of tolerances of ex circuit design features is a matter that concerns both the ex circuit manufacturer and the ex circuit user.
The bend radius rule is just a general guideline.
Documents for manufacturing flex rigid circuit boards basically standards must be regarded such as ipc 2223 ipc 6013 the basic design guide from würth elektronik as well as variant specific design rules and our drying recommendations.
Hardboards designing a flex circuit is only one step away from designing a hardboard.
The most important design difference to keep in mind is the three dimensionality of a flex circuit.
The course was written by john michael pierobon who has an advanced engineering degree from purdue university john michael has taught hundreds of technical courses throughout the world and speaks several languages fluently.
Each supplier may have its own set of design rules and recommendations.
For designers of flexible circuit boards we recommend the ipc 2223 guideline design guidelines for flexible circuit boards which is available from the ipc online store or in german from the fed website.
For flex annular rings need to be larger for flex rather than rigid.
Flex circuits follow different rules for being optimal than rigid circuits.
If you are not aware of this you will struggle with designing them.
