Semi-flex PCBs use specialized FR-4 materials and a specific manufacturing method to create a flex-to-install design that can provide an economical solution for certain applications.
Semi-flex PCBs often can function as a more than adequate solution for certain more advanced applications, while manufacturing is less complicated. Often, it’s a way that combines the best of both worlds. You can bend the board one time to fit the finished product, while not complicating things unnecessarily by laying on a higher level of technology than necessary.
You can always contact your local NCAB Group company if you need further information or assistance, we are happy to help you.
Semi-flex is effectively a ‘standard’ multilayer PCB, built using specific types of FR4 that has been depth to a specific tolerance so that the resulting thinner area provides a flexible / bending section of the traditionally rigid FR4. Semi-flex is suitable for static applications (flex to install), or with very limited number of bends.
To prevent getting it wrong from the start, we have put together our design guidelines, to use as a checklist.
