Our 5-Step EMS Process: From Design to Delivery

Step 1: Quotation & Design Review

Submit your Gerber files and BOM for a rapid quote—typically within 1–2 days. Our engineers perform a free Design for Manufacturability (DFM) analysis to catch potential issues like footprint mismatches or trace width concerns before a single board is built, saving you costly rework down the line.

Step 2: Component Sourcing & Procurement

Step 3: PCB Fabrication

Step 4: PCB Assembly & Soldering

Step 5: Testing, Inspection & Shipment

Frequently Asked Questions

What is turnkey PCB assembly and how does it differ from consignment assembly?

Turnkey PCB assembly means we handle everything—component sourcing, PCB fabrication, assembly, testing, and packaging—from your design files to finished boards ready for market. In consignment assembly, you supply the components and we only perform the assembly. Turnkey is more streamlined, reduces vendor coordination overhead, and leverages our bulk buying power for better component pricing and supply chain risk mitigation.
