DFM · DFT · IPC-A-610 · CM steering

From prototype to high-volume series, with no industrialization redesign phase.

The classic trap: a working prototype that needs six months and a re-spin to hold up in series production. Our technical signature is the opposite — DFM, IPC standards and testability are integrated into the initial schematic. The prototype is already a manufacturable board.

Regulatory frameworks
  • IPC-A-610 Class 2/3
  • IPC-2221
  • IPC-A-600
  • ISO 9001
  • IATF 16949

Native DFM, not patched-on DFM

The cost of late industrialization is well known: every DFM error caught in production costs 10× what it would have cost to fix at design. Component footprint too tight, untented vias on BGA pads, insufficient placement margin for pick-and-place: these problems show up when the CM opens the BOM, not when the prototype works on the bench.

Our schematics and routing are checked against industry-standard capabilities (minimum 0.13 mm spacing for Class 2, 0.20 mm for Class 3, anticipated thermal reliefs). The result: the first production run happens with no PCB mask change.

DFT — so series testing actually exists

Testing a complex PCB at the end of the line requires access points. Many designs neglect this and end up with a custom test bench at €8k per fixture, or worse — production with functional test only.

We systematically integrate: 1.0 mm test points on every power rail, easily contactable JTAG / SWD access, boundary scan for high-pin-count components (FPGA, MPSoC), test fixture cap planned in the mechanical design. The PCB cost adder is marginal (a few cm² of space); the production gain is massive (30 s test per board vs 5 min).

Supplier qualification — France and Asia

The choice of Contract Manufacturer depends on target volume, IP constraints and required quality level. We support our clients across all three scenarios:

  • Low volume (< 1,000 units/year): French manufacturers certified ISO 9001, agile, IP-protected, high unit cost but maximum responsiveness.
  • Mid volume (1,000–50,000): Europe / North Africa / Eastern Europe mix. Good quality-cost-responsiveness compromise, IATF 16949 available for automotive.
  • High volume (> 50,000): Asia (China, Vietnam, Malaysia). Audited manufacturers, strict NDA, statistical-sampling quality monitoring.

See our article: Outsourcing to China vs France.

CM steering — the missing technical interface

Most industrial clients don't have the in-house expertise to dialogue technically with a Contract Manufacturer: writing an ODB++ fab file with the right notes, validating NPI deviations, negotiating component substitutions during shortages.

We hold that interface role. The client keeps IP ownership and commercial steering; we are the technical shoulder between the design house and the factory. On industrial projects, this service cuts NPI lead time by 30 to 50%.

Frequently asked questions

FAQ

IPC-A-610 Class 2 or Class 3?

Class 2 (dedicated products, proven quality) covers the vast majority of consumer and professional industrial products. Class 3 (high-reliability products, where failure is not tolerable) is required for critical medical, aerospace, and certain defence equipment. Class 3 typically adds 15-25% to assembly cost and requires a dedicated certified manufacturer.

How do you handle component shortages?

Anticipation at design: systematic multi-sourcing on critical components (pre-qualified second manufacturer), BOM with validated alternatives, footprints accommodating equivalent components. On running projects, we continuously track end-of-life forecasts (EOL/PCN) for strategic components. See our article: Component shortages.

Can you handle the transition of a product already in series?

Yes, in two cases: (1) series cost optimization on a mature product (re-architecture to reduce BOM, increased automation, mechanical simplification); (2) redesign for component end-of-life when a critical sourcing disappears. Initial diagnostic takes 2 to 4 weeks depending on product complexity.
