Precision Flex PCB Assembly – Fine-Pitch FPC SMT
Fine-pitch components on flexible substrates demand the highest placement accuracy—substrate flexibility makes alignment even more critical. Studio Electronics delivers Precision Flex PCB Assembly with fine-pitch FPC SMT capability. As a specialized provider of PCB assembly in China, our 12 automated SMT lines achieve ±25μm placement accuracy on flexible substrates, supporting 01005 components, 0.3mm pitch BGAs, and fine-pitch QFPs. Combined with custom carrier fixturing and controlled reflow processes, we deliver reliable fine-pitch assemblies for high-density FPC designs. Complete service covers component procurement through final shipping.
| Parameter | Studio Capability | Quality Control |
|---|---|---|
| Component Types | 01005 to BGAs; 0.3mm pitch; fine-pitch QFPs | X-Ray for BGA/QFN; AOI for placement accuracy |
| Placement Accuracy | ±25μm on FPC substrates | Real-time placement verification |
| Carrier Fixture | Precision tooling; flatness <0.05mm | Alignment verification before production |
| Solder Paste | Type 4/5; optimized for fine-pitch | 3D SPI; paste volume verification |
| Reflow Profile | Low-temperature; nitrogen option | Thermal profile validation per design |
| Inspection | AOI; X-Ray; Flying Probe—100% | Documented results per board |
Stage 1: Component Sourcing – Components sourced through authorized distributors. Incoming inspection verifies authenticity. For low volume PCB assembly, we support small-quantity procurement.
Stage 2: FPC Pre-Bake – Pre-baking removes moisture, preventing delamination during reflow.
Stage 3: Precision Carrier Fixture – Custom fixtures with precision tooling pins. Fixture flatness verified before production.
Stage 4: Precision SMT Assembly – 12 SMT lines with ±25μm accuracy. Dedicated fine-pitch placement programs with optimized placement parameters for FPC.
Stage 5: Controlled Reflow – Low-temperature profiles protect polyimide substrates. Nitrogen reflow available for fine-pitch applications.
Stage 6: Quality Inspection – AOI, X-Ray, ICT, Flying Probe—100% coverage. X-Ray specifically verifies BGA/QFN joints on flexible substrates.
Stage 7: Final Assembly & Shipping – Careful handling; anti-static packaging; global logistics.
