Solder mask dam resolution is 3 mil, with routing tolerance maintained within ±0.04 mm for precise board outlines and mechanical features.
We manufacture PCBs with finished copper weights ranging from 0.5 oz to 28 oz (≈1000 μm), supporting both signal integrity and high current applications.
Final board thickness options span from 0.1 mm to 12 mm, enabling fabrication of ultra-thin flex boards to thick, heavy-copper PCBs for power electronics.
WellPCB offers a broad spectrum of PCB base materials, including standard FR4, high-Tg FR4, halogen-free, and CEM-3 for general applications.
For specialized performance, we fabricate with Rogers RO4003 and RO4350 for RF circuits, ceramic substrates for thermal stability, polyimide for flexible PCBs, and metal-core materials such as aluminum and copper for LED and power conversion boards.
We support all mainstream and advanced surface finishes, including HASL (leaded and lead-free), ENIG (Electroless Nickel Immersion Gold), ENEPIG, OSP (Organic Solderability Preservative), immersion silver, and immersion tin.
Selective finish combinations such as ENIG+OSP are available for mixed component assemblies, gold fingers, and edge connectors.
Solder mask is available in green, black, blue, white, yellow, and matte variants with hardness up to 6H and flammability rating UL94V-0.
Our high-resolution legend printing uses white, yellow, or black inks with a minimum line width of 4 mil for clear component markings and assembly labels.
All boards undergo 100% electrical testing via flying probe or bed-of-nails methods. Additional reliability testing includes impedance control with ±3 Ω tolerance, thermal shock testing, and warp/twist validation ≤0.5%.
We provide IPC-Class 2 or Class 3 inspection and reporting upon request for applications requiring elevated reliability standards.
WellPCB is certified to ISO 9001:2015 (Quality), ISO 14001:2015 (Environmental), and IATF 16949:2016 for automotive-grade PCBs.

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.
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.
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.
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.
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%.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
