What Is the PCB Assembly Process at WellPCB?
Send Us Your Files
You begin by submitting your Gerber files, Bill of Materials (BOM), pick-and-place data, and special instructions or assembly drawings. Our engineering team performs a file consistency check and prepares the project for quoting.
Supported file formats include .gbr, .cam, .brd, .pcbdoc, .xls, .csv, and .txt.
Receive Your Quote Within 24 Hours
Once we review your submission, we return a detailed quote within one business day. This includes costs for fabrication, component procurement, assembly, and any testing required. We also include DFM/DFA observations if design adjustments are recommended before build.
Approve and Confirm Your Order
After reviewing your quote, you can confirm the order directly or request changes. We’ll reissue your quote accordingly. Once approved, fabrication and sourcing commence immediately.
PCB Fabrication (if required)
If WellPCB handles fabrication, your boards are built in-house under IPC-6012 standards. We support 1 to 64 layers, finished copper thickness from 0.33 to 28 oz (up to 1000 μm on request), and a trace/space resolution down to 1.8 mils. Surface finish options include ENIG, HASL, OSP, and Immersion Silver or Tin.
Component Procurement
We source your BOM parts from trusted distributors such as Digi-Key, Mouser, Arrow, and Avnet. All parts are verified against footprint, voltage rating, and availability. We do not use gray market or uncertified sources. Procurement is fully traceable and quality-controlled.
PCB Assembly Execution
Our SMT lines use precision stencils for solder paste application, followed by high-speed pick-and-place machines capable of placing 0201s, BGAs (0.2 mm pitch), and fine-pitch QFNs (0.15 mm leads) with ±30 µm accuracy.
Reflow soldering profiles are customized to your board stack-up. Through-hole components are inserted manually or semi-automatically and soldered via wave soldering for full thermal penetration.
Inspection and Testing
Every assembly undergoes multi-phase quality inspection, including visual checks, Automated Optical Inspection (AOI), and X-ray inspection for BGA/QFN joints. Functional quality is validated through In-Circuit Testing (ICT), Functional Circuit Testing (FCT), and, when specified, thermal shock and environmental stress tests.
Cleaning and Coating
Completed boards are cleaned using deionized water and saponifiers to remove flux residues. If your design requires it, we apply conformal coating (acrylic, silicone, or urethane) and cure under controlled conditions. All coatings are UV-traceable and verified during final inspection.
Packaging and Delivery
Boards are sealed in anti-static bags with moisture barrier protection and cushioned with shock-resistant materials. Orders with full tracking and customs documentation are shipped globally via DHL, FedEx, or preferred carriers.

PCB Assembly Services Client Feedback
As an R&D manager, I have had an outstanding experience working with WELL-PCB. For many years, our company has entrusted them with the production, assembly, and programming of the boards developed in our R&D unit, and they have consistently exceeded our expectations.
Hamid Reza Moshayedi
R&D Manager
Their work is very impressively perfect. Today, when they check our company PCB board after assemble. They found a fake short point which many engineers has never found in the past years. But that is just designed so. The PCB board quality is excellent. Their service is also excellent.
MikeZ
My friend introduced WellPCB to me, the first try, a little look forward to. I ordered a 47*72 10ps PCB, and I can’t wait to receive my PCB. So I used expedited service and received my PCB in three days. I tested and soldered the PCB, Quality is really good, silkscreen, plating also great.
