Frequently Asked Questions

What is a flex PCB and how does it differ from a rigid PCB?

A flex PCB (flexible printed circuit board) uses a polyimide or polyester substrate instead of rigid FR4, allowing it to bend, fold, and conform to three-dimensional shapes. Unlike rigid PCBs, flex PCBs reduce overall assembly size and weight, eliminate mechanical connectors, and enable dynamic flexing applications. They are ideal for space-constrained and high-reliability environments.

What base materials are used in SFX PCB's flex PCBs?

How many layers can SFX PCB manufacture for flex PCBs?
