MFGsourcing is your expert partner for custom printed circuit board (PCB) manufacturing, guiding your product seamlessly through every critical phase: Engineering Validation Test (EVT), Design Validation Test (DVT), and Production Validation Test (PVT). We ensure your design is not only functional but also optimized for manufacturability, cost, and unwavering quality.
Our Detailed Technical Manufacturing Process:
DFM & Engineering Review: Your design undergoes a meticulous Design for Manufacturability (DFM) analysis to pre-empt issues and optimize yield.
Material Procurement: We source high-quality, certified laminates (FR-4, High-Tg, Rogers), copper clads, and chemicals from our vetted supply chain.
Precision Imaging & Etching: Using your Gerber files, we plot the circuit pattern onto photoresist and etch away excess copper to form precise traces.
Layer Alignment & Lamination: Multilayer boards are meticulously aligned and fused under high heat and pressure into a single, robust substrate.
Drilling & Plating: Precision CNC machines drill microvias and through-holes, which are then electrodes copper plated to establish conductivity between layers.
Solder Mask & Silkscreen: A protective solder mask is applied (in your chosen color), followed by the silkscreen legend for component identification.
Surface Finish: Application of HASL, ENIG, Immersion Silver, or OSP to protect exposed copper and ensure solderability.
Electrical Testing: 100% Electrical Test (Flying Probe or Fixture-based) performed to verify netlist continuity and isolate shorts/opens.
Final Routing & Scoring: Boards are routed or scored from the production panel to their final dimensions.
Final Inspection & Packaging: A rigorous quality control check precedes secure, anti-static packaging for shipment.
Cost Optimization (VAVE): We implement Value Analysis/Value Engineering (VAVE) principles through material alternates, panelization efficiency, and process optimization to reduce your total cost by 15% to 30% without compromising integrity.
Uncompromising Quality: Our systems are certified to ISO 9001 (Quality Management), IATF 16949 (Automotive), and ISO 13485 (Medical Devices), guaranteeing process consistency and product reliability.
Comprehensive Testing Services: We provide full testing support including In-Circuit Test (ICT), Flying Probe, Boundary Scan, Functional Testing (FCT), and environmental stress testing (thermal cycling, burn-in) to meet your DVT and PVT requirements.
