Data check and DFM review

Send the data before you release it and we will look at it properly — a person, against your build, not a generic rule set. It costs nothing, it takes one to two working days, and it comes back as a written list of what we found rather than a traffic light.

Cost free of charge
Turnaround 1 – 2 working days
Reviewed by engineering
Obligation none
Plainly There is no upload form on this page, and no automatic checker behind it. The review is done by an engineer who reads your data against the intended build. That is slower than a web tool and it is the reason the answer is worth having.

What to send

[ Formats ]

The more of this that arrives at once, the fewer queries come back. If something is missing, send what you have — an incomplete review is still better than none.

Item Format Required
Copper, mask and legend data Gerber RS-274X, ODB++ or IPC-2581 yes
Drill data Excellon, with tool table and plated / non-plated split yes
Board outline as a separate, closed contour yes
Stack-up layer order, material, copper weights, finished thickness yes
Specification or drawing PDF or the fields filled in the enquiry yes
Impedance requirement target, tolerance and which layers if controlled
Assembly drawing PDF, for the mask and legend check helpful
3D model or enclosure data STEP, for the mechanical check helpful

ODB++ and IPC-2581 carry the layer order and the netlist with them, which removes a whole class of ambiguity. Where you have the choice, send one of those rather than Gerber.

What we check

[ Review ]

The review runs in two passes: first whether the board can be built at all, then whether it can be built well and at a sensible price.

01

Feasibility

  • Stack-up buildable and symmetrical at the required finished thickness
  • Track, gap and annular ring against the selected copper weight
  • Drill diameters against the aspect ratio at that thickness
  • Material and finish available for the intended build
02

Manufacturability

  • The thirteen recurring layout faults, checked one by one
  • Solder mask dams, coverage and oversize consistency
  • Copper-to-edge, cut-out radii and routing tolerances
  • Legend clipping and character height
03

Cost and panel

  • Panel utilisation for the given outline, and what a few millimetres would change
  • Whether the structure class or via technology can be relaxed without a redesign
  • Whether the specified class is the one the application needs
  • Test coupon placement where a layer is impedance-controlled
04

Documentation

  • Copper data, drawing and specification consistent with each other
  • Layer mapping unambiguous without a phone call
  • Required markings present: UL, date code, revision, factory field
  • Anything the plant would otherwise silently interpret

What comes back

[ Result ]

A written list, grouped the same way as above: what blocks production, what we would change, and what we noticed but left alone. Where we have corrected something in CAM, it is named — a silent correction is a change to your board that you did not approve.

Email the package with a note on the intended build and the quantity. If you need an NDA in place first, say so and we will send ours the same day.
