Why Choose Us for Rapid Flex PCB Prototyping?
Raw Materials In-Stock: Immediate access to standard adhesive and adhesiveless Polyimide (PI) laminates, eliminating material supply delays.
2-Hour Rapid DFM Analysis: Our dedicated CAM team inspects your Gerber files and stackup within 2 hours of submission to identify layout risks, broken traces, or drill clearances.
100% In-House Processing: From UV laser cutting and plasma desmearing to flying probe electrical testing and automated optical inspection (AOI), all steps are performed under one roof.
Submission Checklist: How to Prevent your Quick Turn Delays
To avoid engineering holds and lock in your 24–48h ship window, verify that your design package contains:
1,Gerber Files: RS-274X or ODB++ format including all copper layers, soldermask/coverlay, silkscreen, and drill files.
2, Mechanical & Stiffener Outlines: Clearly marked contour layers with stiffener dimensions, materials (FR4/PI/SUS), and exact thicknesses.
3,Fabrication Notes / Drawing: Ensure you have detailed specification for your flex PCB, like Stack up, board thickness, copper thickness, surface finish, soldermask and other special requirments.
Frequently Asked Questions (FAQ)
What is the minimum turnaround time for quick turn flexible PCBs?
Our fastest turnaround time for single- and double-sided flexible PCBs is 24 to 48 hours after EQ closed. Complex multilayer flex and rigid-flex prototypes can be delivered in as fast as 3 to 5 working days.
What materials do you recommend for dynamic flexing applications?
For dynamic flex applications (continuous bending), we recommend adhesiveless Polyimide base substrates paired with Rolled-Annealed (RA) copper foil, as RA copper provides significantly higher ductility and fatigue resistance compared to standard Electro-Deposited (ED) copper.
Can you assemble SMT components on quick turn flex circuits?
Yes. We offer turnkey quick-turn assembly services (PCBA), including component sourcing, laser-cut SMT stencil fabrication, carrier design, and reflow/manual soldering for flexible and rigid-flex boards.
How do you verify the quality of fast-turn flex circuits?
Every board will have the quality checks, including automated optical inspection (AOI), 100% flying probe or test fixture electrical testing, cross-section microscopic analysis, and solderability testing per IPC-6013 standards.
