The Stage Most Suppliers Get Wrong
Low volume medical production sits between prototype and mass production — and it carries the risks of both. Most contract manufacturers treat these orders as oversized prototypes or undersized production runs. Neither works. The result is process data that cannot support validation documentation, and yield results that don’t predict what happens at scale.
At this stage, three questions matter more than unit price:
Will the process be stable enough to generate valid PQ data?
An unstable process at this stage means re-validation — not just rework.
Will component changes be controlled and documented without chasing suppliers?
An undocumented substitution at this stage can invalidate your change control record.
Will production records scale cleanly into your DHR at full volume?
Records structured wrong now are wrong at every volume that follows.
Process Validation Support — IQ, OQ, PQ
Installation Qualification
Verifying the inputs are correct before the process runs
Equipment not calibrated at this stage means IQ cannot close — and nothing that follows is valid.
- Equipment calibration certificates: SMT placement machines, reflow ovens, SPI and AOI systems
- Process parameter specifications: stencil aperture, paste volume tolerances, reflow zone temperatures, nitrogen O₂ levels
- Component lot documentation: supplier certificates of conformance per BOM line item
- Facility records: ESD control logs, MSL storage condition documentation
Operational Qualification
Demonstrating the process stays in control under defined operating conditions
OQ data is only as good as the range it was tested across. Nominal-only testing is not OQ.
- Reflow profile validation: thermocouple traces across multiple board positions, peak temperature uniformity within ±1°C
- SPI process capability data: paste volume, height, and area coverage per pad across full panel (Cpk within tolerance)
- Placement accuracy verification: fiducial correction logs and first-article coordinate measurement results
- AOI and X-ray rejection data across OQ build runs, classified by defect type
Performance Qualification
Demonstrating consistent conforming output across independent production runs
Three runs is the minimum. Consistency across all three is the only thing that matters.
- Minimum three independent production runs with complete batch records per run
- FPY data per run with lot-to-lot variation analysis — target FPY >98%
- Unit-level traceability: component lot, paste batch, reflow profile, inspection result, and functional test outcome per board serial number
- FAI report for the first PQ build, structured for inclusion in your 510(k) or CE MDR technical file
Validation Protocol Review
If needed, Sugamed's engineering team can review your draft IQ/OQ/PQ protocol before production — confirming that process parameters are measurable, acceptance criteria are achievable, and record formats align with your DHR structure.

Supply Chain Control
BOM Lifecycle Screening
Every component is screened for EOL (End-of-Life) and NRND status before production commitment.
Controlled Substitution Process
No substitution proceeds without OEM written approval. Technical justification is prepared by Sugamed and provided for OEM review.
Inventory Reservation for Validation Runs
For IQ/OQ/PQ builds requiring consistent component lots across multiple runs, Sugamed reserves inventory in advance — eliminating component lot variation as a confounding factor in your PQ data.
Built to Scale Without Re-Validation
The process validated at low volume is the process that runs at full scale — same equipment, same parameters, same documentation structure, same engineering team.
When your volume scales, no process re-qualification is required. Production records are structured identically across all build volumes. Component sources remain consistent unless formally changed through your change control process.

FAQ
Do you have ISO 13485 certification?
Yes. We’re ISO 13485 certified, which means the quality system covers the entire production process — document control, batch records, traceability — not just the certificate itself. If you need documentation for internal audits or regulatory submissions, we can provide it.
Can you provide full traceability for small orders?
Yes, even for a single board. Each order comes with batch records and key process data. We treat prototype runs with the same documentation discipline as production — because we know medical projects get audited at any stage.
What's your MOQ?
No MOQ. You can start with 1 piece. Most of our medical customers begin with a small verification run before scaling, and we’re set up to support that workflow.
How fast can you turn around prototypes?
The standard lead time is approximately 7–15 days, depending on the complexity of the board.
Do you provide DFM feedback?
Yes. Before we start, our engineering team reviews your design and flags potential issues — pad sizing, clearance, stack-up — anything that could affect yield or reliability. It’s included at no extra charge and usually saves time overall.
What if something doesn't come out right?
We’ll tell you clearly what happened and why. For medical projects especially, we’d rather give you a straight answer than a vague one. If it’s a process issue on our end, we rerun it. If it’s a design issue, we’ll show you exactly where so you can decide how to proceed.
