Flex PCB Design Tips

Flex PCB Design Tips post thumbnail image

2015 has been all about flex here at Sierra. We launched our new flex PCB manufacturing capabilities, we wrote a Flex Design Guide, and we even co-presented a free flex webinar with Altium.

Some of the design questions we resolve include:
Preferred hole and pad sizes for flexible PCBs.
Alternative prepreg materials for joining flex and rigid materials
Whether stacked microvias or blind/buried vias are more cost-effective in HDI rigid-flex designs.

Some of the manufacturing and assembly questions we resolve include:
Tooling holes and fiducials
Avoiding blistering
