Buy PCBA: Printed Circuit Board Assembly Manufacturers & Factory

To provide a fully accounted, fixed-price turnkey PCBA quotation, we require: (1) Complete Gerber RS-274X or ODB++ files including all copper, solder mask, silkscreen, and drill layers; (2) A hierarchical Bill of Materials (BOM) in Excel format with designated manufacturer part numbers (MPNs), reference designators, package footprints, and acceptable alternates; (3) Centroid / XY Pick-and-Place data for SMT coordinate mapping; and (4) Assembly drawings specifying conformal coating boundaries, special solder finishes, or programming/test routines.

We operate a multi-tier component protection protocol. First, active silicon and passive components are sourced exclusively from authorized franchise distributors (such as Arrow, DigiKey, Mouser, Avnet, and direct factory reps for TI, ADI, STMicroelectronics, and Microchip). Second, incoming inspection in our Bao'an facility includes decapsulation verification, pin plating indentation checks, laser marking surface texture validation, and LCR bridge testing under ISO 9001 and AS6081-inspired quality guidelines.

Our rapid NPI (New Product Introduction) quick-turn service delivers assembled boards in as little as 3 to 9 working days. For standard multi-layer rigid boards (2 to 8 layers) where components are locally stocked, PCB fabrication and stencil laser-cutting take 48-72 hours, with SMT placement, reflow, inspection, and functional verification completed within an additional 48 hours. Expedited logistics options (DHL, FedEx Express) provide door-to-door delivery within 3-4 days to the US and Europe.

Yes. We specialize in hybrid lamination builds combining high-frequency PTFE/ceramic substrates (such as Rogers RO4350B, RO4003C, Taconic) with standard High TG FR-4 (such as Shengyi S1000-2, ITEQ IT-180A). This hybrid approach provides low dielectric loss (Df) and consistent dielectric constant (Dk) along high-speed RF microstrip paths while keeping overall material costs economical on inner digital ground and power planes.

Every assembly is subjected to multiple verification gates: (1) Inline 3D Solder Paste Inspection (SPI); (2) Automated Optical Inspection (AOI) before and after reflow; (3) Automated X-ray Inspection (AXI) for all area array packages (BGAs, CSPs, QFNs); (4) First Article Inspection (FAI) with digital LCR comparison against the master netlist; and (5) Custom Functional Circuit Testing (FCT) via bed-of-nails or custom test harnesses to verify live operating voltages, signal transitions, and sensor telemetries.

We maintain complete flexibility with zero strict minimum order quantities. We support prototype batches starting from 1 to 5 pieces for R&D engineering validation, scaling smoothly into pilot batches of 50 to 500 pieces, and supporting full-scale mass production orders exceeding 100,000 units. SMT feeders and YAMAHA lines are configured for rapid changeover to accommodate agile high-mix, low-to-medium-volume (HMLV) programs seamlessly.

Yes. Beyond surface-mount and through-hole board assembly, our Bao'an facility houses mechanical assembly cells equipped for complete product integration. Our capabilities include injection mold fabrication, plastic chassis production, precision CNC metal machining, 3D printing of conceptual prototypes, display integration, custom silicone keypad fitting, automated screw driving, potting, ultrasonic welding, custom retail box packaging, and final barcoding.

ECOs are governed via our digital Manufacturing Execution System (MES). When a revision occurs, our project engineer freezes current work-in-progress (WIP), identifies affected lots across raw PCB, kit kitting, and SMT stages, and issues a formal delta impact assessment. If bare boards require rework, laser cutting or jumper rewiring is evaluated against pure re-fabrication to ensure mechanical and electrical reliability is never compromised.
