Winchester-based PCB design house Professional Circuit Designs (PCD) is now offering design for manufacture (DFM) checks for Gerber and ODB++ files.
“These checks would normally be done by the [PCB] manufacturers. If we do the DFM checks, the customer can send clean data to the manufacturer and avoid unpredictable delays,” company CAD operations leader John Stevens told Electronics Weekly.
PCD can also modify the Gerber or ODB++ files to pass DFM checks against ERFs (electronic rules files) of several PCB makers, giving the customer a choice of production site with a common data set.
Turn-around is dependent on design complexity, and typically a day, said Stevens.
PCD has been designing PCBs for 18 years and provides services from schematic capture onwards, on boards with up to 24 layers. It uses Mentor Graphics’ tools – including Valor NPI, originally licenced for in-house DFM checking.
“Valor NPI is a very expensive tool and complex to set-up. It is certainly not a tool every design house would have,” said Stevens. “We are now in the unique position of being able to offer a DFM checking service on artworks from any EDA vendor – not just for our own customers.”
On ODB++ files, DFM checking can include net-list analysis with open and short analysis.
