Flex Circuit Design Rules

The bend radius rule is just a general guideline.

Flex circuit design rules.

During testing you are trying to see how many cycles the flex circuit can withstand. Flex designs require button plating. 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. Designing flexible circuits is sponsored by all flex.

The most important design difference to keep in mind is the three dimensionality of a flex circuit. Pcb design and layout will also be affected by your planned circuit density and line spacing. Flex circuits follow different rules for being optimal than rigid circuits. 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.

Flex rigid design guide poster. Figure 5 1 designing with a bias for copper improves the circuit s dimensional stability. Creative bending and flexing can save space and layers. Design rules for routing conductors on flexible circuits can be found in the ipc 2223 sectional design standard for flexible printed boards.

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. Design guide for flex rigid pcbs. Flexible circuits design guide. It may not be practical for all applications.

If you are not aware of this you will struggle with designing them. Hardboards designing a flex circuit is only one step away from designing a hardboard. Understand that flex and rigid flex design rules are different. Design differences flex circuit vs.

However because flex circuit is unique it is a good idea to use the same material in prototype that will eventually be used in volume production. We would be pleased to help you in delivery panel design for rigid flex solutions. Flex and rigid flex boards. Also if you are using flex circuit design software that might not match up to the available guides for your flex circuits you will not have an easy time.

Using your circuit design software program position connector footprints in the proper locations and route conductors per schematic or net list. See here the digital version or order here as paper version for free. Heterogeneous system rigid circuit board wiring harness flex soldered in or plugged detachable. 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.

Each supplier may have its own set of design rules and recommendations. Below is a general rule on a flex circuit bend radius. Applications which go beyond our standard design rules require technical clarification with our product management.
