Flexible circuit prototype offers a great opportunity for the packing of electronic designer and engineering designer. They are very versatile electronic wires and systems that may be bent, shaped, twisted or folded into the endless dimensional configuration. They are much better than the inflexible and rigid PCB or printed circuit boards. The added dimension makes the flex circuit a dream of engineering but adding some flexibility can make the entire design greatly flexible.
Various kinds of manufacturing techniques are used for flexible circuit prototype. When it is the rigid and printed circuit, it would be more stable dimensionally. There is standard polyimide film that is employed as the main component in about 95% of flex circuits. The increase in the dimensional variability implies that the flexible circuit needs various design rules. The rules are more when compared to printed circuit boards.
How to Make the Design More Flexible?
To make the design more ready for fabrication, producible and robust, you need to consider the following:
• During the making of the flexible circuitry or circuit board prototype, there can be dimensional change after an exposure to the processes like copper plating, pumice scrubbing and etching. When it comes to the design rules of flexible circuitry, larger tolerances are required. This accommodates the registrations for stiffeners, cover film and the die cutting. You need to be careful about it.
• There can be more solder spacing between the pads and also adjacent traces. This design compromise is the direct consequence of the first point or flaw.
