FAQ
Prototype PCB Assembly refers to the process of precisely assembling selected electronic components onto a customized printed circuit board (PCB) according to circuit design requirements, and producing a prototype of the circuit board that can be tested and functionally verified.
Flex PCBs are primarily made from polyimide (PI) or polyester (PET) substrates with copper foil layers. We also use adhesiveless laminates for high-reliability applications. Coverlays, stiffeners (FR4 or stainless steel), and surface finishes (ENIG, OSP) are added depending on the design.
Lead times depend on complexity and quantity:
- Prototype Flex PCBs: 3–7 business days
- Production Runs: 7–20 business days
Expedited options are available for urgent projects — contact us for a custom quote.
- Flex PCBs use flexible base materials and are designed to bend, fold, or twist during use.
- Rigid PCBs are built on FR4 substrates and are not designed for movement.
Flex PCBs save space, reduce weight, and improve durability in dynamic environments.
Absolutely. Our engineering team offers free DFM reviews, helping you optimize your design for manufacturability, cost efficiency, and long-term reliability. Upload your Gerber files, and we’ll evaluate them before production begins.
