Custom FR4 PCB Fabrication – Quick Turn & Low Cost

Every electronics project begins with a unique design. Whether you’re developing a medical device, industrial controller, IoT sensor, or consumer product, your PCB requirements are specific to your application.

We offer custom FR4 PCB fabrication – building boards exactly to your Gerber files – with quick turnaround times and low cost that fits your budget. No forced standardizations. No hidden fees. Just reliable, custom PCBs delivered fast.

What Makes Custom Fabrication Different?

Aspect	Standard Catalog	Custom Fabrication (Us)
Design	Pre-designed boards	Your design, your Gerber files
Layer stackup	Fixed standard stackup	Custom – any stackup you specify
Board shape	Rectangular only	Any shape – routed to your outline
Materials	Limited options	Any FR4 grade, any copper weight
Finishes	Limited options	Any finish – ENIG, HASL, OSP, etc.
Quantity flexibility	Fixed pack sizes	Any quantity – 5 to 100,000+
Turnaround	Varies	Quick turn available (3-7 days)
Cost	Higher per board (retail)	Lower per board (wholesale)

Quick Turn + Low Cost – The Best of Both Worlds

Many PCB manufacturers force you to choose:

Trade-off	Typical Outcome
Quick turn = expensive	Pay 2-3x for faster delivery
Low cost = slow	Wait 3-4 weeks for budget pricing

We offer both: Quick turn and low cost.

Service Level	Turnaround	Cost Level
Standard	7-12 days	Lowest
Quick turn (5-day)	5 working days	Low (+20-30%)
Express (3-day)	3 working days	Moderate (+50-70%)
Emergency (24-48h)	1-2 working days	Higher (+100-150%)

No matter which speed you choose, our base pricing is competitive. You only pay a premium for faster speed – not for the custom nature of your design.

New to custom PCB fabrication? Start with a small prototype order (5-10 pieces) to validate our quality before scaling up.

Q1: Why should I use the same supplier for prototype and mass production?

Reason	Benefit
No re-qualification	You already know our quality
No file transfer	We keep your design files
No new tooling	Panelization and fixtures already set up
Consistent quality	Same processes, same result
Faster production lead time	Tooling ready – no setup delays
Single point of contact	Same team, same communication

Switching suppliers adds risk, delay, and cost. Why do it?

Q2: Can you handle small prototype quantities (5-10 pieces)?

A: Yes – we specialize in prototypes.

Quantity	We Accept
5-20 pieces	Yes – prototype pricing
21-100 pieces	Yes
101-500 pieces	Yes
501+ pieces	Yes – production pricing

No MOQ for prototypes. Order exactly what you need for validation.

Q3: Will my per-board cost decrease when I move to mass production?

A: Yes – significantly.

Stage	Quantity	Per-Board Cost
Prototype	10 pieces	Higher (fixed costs spread thin)
Pilot	100 pieces	Moderate
Production	1,000 pieces	Lower
Mass production	10,000+ pieces	Lowest

Same supplier, same quality, lower price as you scale.

Q4: Do I need to requalify my design for mass production?

A: No – we use the same Gerber files and specifications.

Step	Action
Prototype approved	Design validated
Same files for production	No changes – we use approved files
No re-engineering	Tooling already set up
No re-qualification needed	You already know our quality

Seamless transition from prototype to production.

Q5: How do you ensure consistent quality across all volumes?

Quality Element	Applied Equally to All Orders
ISO9001 processes	Yes – documented and audited
Incoming material inspection	Yes – every batch
AOI (Automated Optical Inspection)	Yes – every board
100% electrical test	Yes – every board
Final visual inspection	Yes – every board
Traceability	Yes – lot-level tracking

Quality doesn’t depend on quantity. 10 pieces or 10,000 – same standards.

Q6: What if my prototype design changes before mass production?

A: No problem – we handle revisions.

Situation	Our Process
Minor revision (same layer count, same stackup)	Update Gerber files, new DFM review (free)
Major revision (different layer count or stackup)	New stackup design, new quotation
No penalty for changes	Pay only for new boards

Designs evolve. We evolve with them.

Q7: Can you hold my tooling (panelization, test fixtures) for future production runs?

A: Yes – we keep your tooling on file.

Tooling Item	We Keep For
Panelization layout	Indefinitely – for repeat orders
Drill files	Indefinitely
Test fixtures (flying probe)	Indefinitely
Custom test fixtures	Indefinitely (if customer paid)

No setup fees for repeat orders – tooling already exists.

Q8: What if I need to scale up quickly from pilot to mass production?

A: We have capacity for rapid scaling.

Volume Ramp	Our Response
100 to 1,000 pieces	Standard – no issue
1,000 to 10,000 pieces	Adjust schedule – typically 1-2 weeks notice
10,000 to 50,000+ pieces	Strategic planning – discuss forecast

We grow with you. Tell us your forecast – we plan capacity accordingly.

Q9: Do you offer scheduled deliveries for ongoing production?

A: Yes – we work to your schedule.

Delivery Schedule	We Can Do
Weekly	Yes – same quantity each week
Bi-weekly	Yes
Monthly	Yes
Quarterly	Yes
As-needed (pull system)	Yes – with VMI (Vendor Managed Inventory)

Reduce your inventory holding costs with just-in-time delivery.

Q10: How do I get started with prototype-to-production service?

A: Simple process:

Upload Gerber files for prototype
Receive free DFM review and quote
Order prototype (10-20 pieces)
Test and validate your design
Notify us to scale – we use same files and tooling
Order production quantity (any volume)

No need to find another supplier when you scale. We are your partner from first prototype to millionth board.
