About MWX PCB
Engineering-oriented PCB support with practical manufacturing experience.
MWX PCB is led by David Xu, an independent PCB business developer in Shenzhen with more than 13 years of hands-on PCB experience across front-line production processes, quality control, business communication, SMT, DIP, EMS, and electronics manufacturing facilities.
The focus is clear: prototype PCB projects, low-volume PCB production, DFM communication, and flexible support for European and North American hardware teams that need a responsive manufacturing contact in China.
Positioning
MWX is not presented as a large PCB factory. It is positioned as engineering-oriented PCB manufacturing support for projects where communication, DFM feedback, and flexibility matter.
Services
Support for prototype, validation and small-batch PCB work that needs engineering follow-up.
Low-Volume PCB Production
Small-batch PCB production for NPI, pilot builds, field trials, and early-stage product launches.
DFM Review
Manufacturing feedback on stack-up, materials, drill design, copper, impedance, solder mask, panelization, and process risk.
Engineering Communication
Clear technical follow-up on manufacturability, production questions, inspection requirements, and delivery priorities.
Typical Capabilities
PCB technologies commonly required in prototype and low-volume builds.
PCB types1-50L rigid PCB, HDI, rigid-flex, high-frequency, high-speed, heavy copper and PCBA support
Process capability3/3 mil outer line / space, 0.15 mm finished mechanical hole, 20:1 aspect ratio, project dependent
Copper capabilityOuter copper up to 30 oz and inner copper up to 15 oz on advanced heavy-copper projects after review
Surface finishHAL LF, immersion gold, ENEPIG, immersion tin, immersion silver, OSP, hard gold finger, carbon ink and peelable solder mask
Special processPOFV, buried/blind vias, back drilling, controlled-depth milling, hybrid material PCB, counterbore and copper via plugging
Capability is matched to the project.
MWX reviews each technical requirement and confirms a practical PCB production route before the order starts. The goal is to reduce back-and-forth, identify process risks early, and keep prototype or low-volume projects moving.
Applications
Built for hardware teams that design real products.
Quality & DFM Control
Manufacturing risk is easier to fix before production starts.
Pre-production DFM
Review Gerber data, stack-up, minimum line and spacing, via design, controlled impedance, copper balance, and special material requirements.
Process Confirmation
Confirm whether the board needs HDI, back drilling, buried/blind vias, high-frequency material, heavy copper, or special surface finish.
Inspection Follow-Up
Coordinate checks such as AOI, electrical test, dimensional inspection, impedance test, and final outgoing quality control where applicable.
Workflow
A practical path from files to finished boards.
Step 1
Share Gerber & Requirements
Send Gerber, BOM, stack-up notes, quantity, lead-time target, and any special requirement.
Step 2
DFM & Quotation
Review manufacturing risk, confirm process capability, and provide a clear quotation.
Step 3
Production Follow-Up
Follow PCB fabrication progress, answer engineering questions, and monitor key production steps.
Step 4
Delivery & Next Build
Support shipping, feedback review, and preparation for the next prototype or low-volume batch.
Insights
Manufacturing notes for engineers and buyers.
DFM Topic
What to check before releasing a prototype PCB order
Stack-up, material, minimum drill, impedance, surface finish, and panelization can all affect delivery.Engineering Note
Why stack-up and impedance should be confirmed before quotation
Clear stack-up and controlled impedance notes help avoid price changes, delays, and engineering questions after release.Industry View
Why backup PCB suppliers matter for NPI projects
Prototype and pilot builds need flexible communication when schedules, files, and quantities change fast.Our Strengths
Engineering Communication
Direct manufacturing discussion without heavy sales language.
Flexible Project Fit
Good for prototypes, urgent orders, and low-volume production.
Shenzhen Manufacturing Access
Close to PCB, SMT, EMS, testing, logistics, and component supply-chain resources.
Practical DFM Support
Process-focused feedback before issues become production delays.
Backup Supplier Mindset
Useful when existing suppliers are overloaded, slow to reply, or not flexible with small batches.
Low-Pressure Cooperation
Clear project discussion first, quotation second, long-term relationship always.
