This ensures complete traceability, lead time consistency (standard: 5 to 6 days; expedited: 24 to 48 hours), and quality oversight for PCBs up to 64 layers and 40:1 aspect ratio.
Certified to Global Standards
WellPCB is certified to ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental), ISO 13485:2016 (Medical), and IATF 16949:2016 (Automotive), with UL-listed PCBs manufactured to IPC-6012 and IPC-A-600 Class 2 and Class 3 standards.
All PCBs are RoHS and REACH compliant.
True One-Stop Electronic Manufacturing
Our services go beyond fabrication.
We include SMT/through-hole PCB assembly (BGA/QFN to 0.2 mm pitch), full turnkey sourcing from authorized distributors (Mouser, Digi-Key, Arrow), custom wire harnesses, firmware programming, flying probe and functional testing, and full box build assembly.
Transparent Quoting & No Hidden Costs
Get instant quotes based on exact technical specifications, layer count, surface finish, copper weight, solder mask color, board thickness, etc.
We support multi-currency payments (USD, EUR, AUD), and guarantee no surprise charges during high-mix or HDI production runs.
Engineering-Grade Technical Support
Our support team includes PCB design-for-manufacturing (DFM) experts, stackup planners, and SMT process engineers who assist with Gerber, BOM, and stencil file review.
We identify manufacturability risks (eg. solder mask clearance, via annular ring violations) before production begins.
Rapid Prototyping with Scale-Up Continuity
Prototype from a single unit to mass production (up to 10,000+ boards) using the same tested process chain.
All boards are built with consistent documentation, testing, and quality checkpoints to ensure functional and dimensional consistency throughout your product lifecycle.
Our PCB Manufacturing Process
We manufacture various custom wiring harnesses engineered to meet the electrical, environmental, and mechanical demands of specialized applications across multiple industries.
1
Gerber Review & CAM Optimization
All incoming Gerber files undergo Design for Manufacturability (DFM) checks and CAM engineering, including layer alignment, drill/rout verification, netlist integrity checks, soldermask clearance review, and impedance modeling.
2
Inner Layer Imaging & Etching
Photoresist imaging uses LDI (Laser Direct Imaging) systems to define inner-layer copper patterns. Etching removes exposed copper, achieving line/space resolutions as tight as 1.8 mil.
3
AOI for Inner Layers
Automated Optical Inspection (AOI) detects short/open circuits, line width variations, and registration defects on each inner layer prior to lamination, ensuring early defect containment.
4
Multilayer Lamination with Prepreg
Layer stackups are consolidated using high-Tg FR4 or specialty prepreg under controlled pressure/temperature cycles. Up to 64 layers are supported, with impedance-controlled dielectric thickness targeting ±10%.
5
Drilling (Mechanical/Laser)
High-precision CNC drills (±0.025 mm accuracy) form through-holes and vias down to 0.08 mm. For HDI boards, CO₂/UV laser drilling enables stacked microvias, blind/buried vias, and via-in-pad structures.
6
Electroless Copper Deposition
A catalytic copper layer is chemically deposited to create a conductive base in all hole walls. This seed layer is essential for ensuring uniform subsequent electrolytic plating.
7
Outer Layer Pattern Plating
Electrolytic copper plating is performed with controlled current density (20 to 30 ASF) to thicken traces and via barrels. Nickel/gold plating may also be applied to selected areas.
8
Outer Layer Etching
Outer layers are developed using photolithography and etching to define final circuit patterns. All conductive paths are verified against the netlist and CAM data.
9
Soldermask Application
Liquid photoimageable (LPI) soldermask is screen-coated or spray-applied, then UV-imaged and developed to expose pads and vias. Supported colors include green, black, blue, white, yellow, and matte options.
10
Surface Finish Deposition
Surface finishes such as ENIG, ENEPIG, HASL (leaded/lead-free), OSP, immersion silver, and tin are applied to exposed pads. These finishes ensure solderability and long-term oxidation resistance.
11
Silkscreen Printing
High-resolution legend ink is printed using screen or inkjet methods, with white, yellow, or black options. Line widths down to 4 mil ensure clear component identification.
12
100% Electrical Testing
All boards undergo electrical testing via flying probe or bed-of-nails to verify netlist compliance, continuity, and isolation. High-voltage and high-resistance leakage testing can be applied for Class 3 builds.
13
Profiling, V-Scoring, Routing
PCBs are separated using mechanical routing, V-score, or punch tooling. Profiling tolerance is maintained at ±0.04 mm to match mechanical enclosure requirements.
14
Visual QA Inspection
Final visual inspection checks for soldermask integrity, surface finish consistency, silkscreen legibility, and board edge quality. IPC-A-600 criteria guide acceptance levels.
15
Anti-Static Packaging
Boards are vacuum-sealed in anti-static packaging with desiccant packs and humidity indicators. Panel or single-unit packaging is available per order specs.
16
Certified Delivery & Documentation
Each shipment includes test reports, CoC (Certificate of Conformance), dimensional inspection results, and RoHS/REACH compliance documentation as required.

Client Feedback About Our PCB Manufacturer Services
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.
