10 questions to ask before placing your next order
Introduction
You‘ve spent weeks designing your PCB. The schematic is clean, the layout is optimized, and you’re ready to send it to production.
But choosing a manufacturer feels like a gamble.
Cheap quotes from overseas. Fast delivery promises. Certification badges everywhere. How do you separate reliable partners from factories that will deliver late — or worse, deliver boards that don‘t work?
This guide walks you through 10 practical questions to ask before placing your next PCB order. Whether you’re ordering 50 boards or 5,000, these questions will help you find a manufacturer you can trust.
1. What‘s Your Experience with Small Batches?
Not every factory is set up for low-volume production.
Large manufacturers often push small batches to the back of the line. Some quote high setup fees specifically to discourage small orders.
What to look for:
- Clear minimum order quantity (MOQ) policy — ideally 5-10 boards
- Transparent pricing for prototypes and small batches
- No unexplained "small batch fees"
Red flag: They take days to respond to your quote request or keep asking you to increase quantity.
2. Do You Offer Pre-Shipment Verification?
You can‘t afford a bad batch that only fails after arrival.
A reliable manufacturer will show you what they built before shipping. This is especially critical for small batches where every board counts.
What to look for:
- Pre-shipment photos of your actual boards
- Optional video or detailed inspection report
- Willingness to hold shipment until you approve
Red flag: You ask for photos and they say "trust us, it‘s fine."
3. How Do You Handle Component Sourcing?
For PCB assembly (not just fabrication), component sourcing is often the biggest variable.
Many small-run manufacturers will substitute parts without telling you — which can break your design.
What to look for:
- They source from authorized distributors (DigiKey, Mouser, LCSC, etc.)
- They request exact MPNs (manufacturer part numbers), not generic descriptions
- They will NOT substitute without your written approval
Red flag: They say "we'll find equivalent parts" without asking you first.
4. Can You Break Down Your Quote?
Small batch pricing can feel like a black box. A good manufacturer will open it.
What a transparent quote includes:
- One-time tooling / setup fee
- Per-board fabrication cost
- Component cost (if they‘re sourcing)
- Assembly cost per board
- Testing cost (if applicable)
- Shipping cost
Red flag: A single lump sum with no breakdown. You have no idea what you’re paying for.
5. What‘s Your Typical Lead Time?
Lead times have stretched across the industry. Honest manufacturers will tell you exactly where they stand.
What to look for:
- Different lead times for fabrication vs. assembly
- Clear explanation of what adds time (special materials, complex stackups, component availability)
- Realistic estimates, not "always 5 days"
Red flag: They promise 5-day delivery on everything, no matter the complexity.
6. Do You Offer DFM Feedback Before Production?
The best manufacturers catch your mistakes before you pay for them.
A quick DFM (Design for Manufacturing) review can identify issues like undersized annular rings, missing fiducials, or problematic trace spacing.
What to look for:
- Free DFM check included in the quote process
- Specific, actionable feedback (not just "fix your files")
- Engineers who ask clarifying questions about your design
Red flag: They say "yes" to everything without asking any questions.
7. What Quality Certifications Do You Hold?
Certifications aren‘t everything — but for certain industries, they’re non-negotiable.
Red flag: They list every certification possible but can‘t produce valid certificates when asked.
8. How Do You Handle Defects or Rework?
Problems happen. What matters is how the manufacturer responds.
What to look for:
- Clear warranty policy (typically 6-12 months)
- Process for reporting defects (photos, documentation required)
- Rework or replacement terms (who pays for what)
Red flag: No clear policy, or they say "we’ve never had a defect" (impossible).
9. Can You Provide References from Similar Projects?
If you‘re designing for medical, automotive, or RF, ask for relevant experience.
A manufacturer that routinely builds 2-layer IoT boards may struggle with 12-layer HDI for an imaging device.
What to ask:
- "Have you built boards with similar layer count and technology?"
- "What was the biggest challenge on that project?"
- "Can I speak with that customer?"
Red flag: They say "yes" but can’t provide specifics or references.
10. What‘s Your Communication Like During the Quote Process?
The quoting process tells you everything about how they‘ll treat your order.
What to look for:
- They respond within 24 hours (time zone differences are normal, silence is not)
- They ask specific questions about your design (not just "send files")
- They explain their answers, not just give one-word replies
Red flag: Slow responses, vague answers, or no questions at all.
