PCB engineering tools
Free calculators and file checks for hardware engineers from Comtec Labs, an electronics manufacturer in Vaasa, Finland.
The tools work with your own numbers and files. Calculators and file checks run in your browser: Gerber files and BOMs are not uploaded unless you send them with a quote request. The BOM checker sends only the part numbers and manufacturer names it looks up.
Results are engineering estimates for design decisions. Before a production release, confirm critical values with the board fabricator, the component data sheets and the standards themselves.

PCB calculators
Trace width for a current and temperature rise (IPC-2152), microstrip and stripline impedance (IPC-2141), via current capacity and MSL floor life (J-STD-033).

Gerber viewer and DFM check
Open a Gerber zip in the browser, see the board in 3D and check it against the limits of our assembly process before you order.
Open the tool -
Panelization preview
Lay your board out in a production panel: number of boards, rails, fiducials and V-score or tab separation, previewed from the board outline.
Open the tool -
BOM lifecycle and stock checker
Check the part numbers of a BOM for lifecycle status and distributor stock. Only the part numbers and manufacturer names are sent for the lookup, not the file.
Open the tool -
BOM compare
Compare two revisions of a bill of materials: added, removed and changed designators and part numbers, quantity changes and DNP, with CSV export.

Landed cost: Europe vs Asia
Compare the total landed cost per unit and per year of building in Europe or in Asia: freight, duty, inventory, payment terms, quality, travel and NRE.

Quote request with board check
Drop your Gerber, BOM and pick-and-place files into the quote wizard: it previews the board and lists design findings before you send the request.

Design ready? Send the files with a quote request: with a complete file set the quote comes usually the same working day, at most within 1 working day.
