Typo receives a prototype job from their customer.
The design exceeds minimum trace spacing capabilities.
Typo has to either notify the customer, placing the job on hold, and wait for new artwork, or rectify
the situation themselves by modifying the offending traces to comply with their capability. Typo modifies the
design to minimize production delays.
Typo builds the prototype...
- PCB signal quality ends up being different than design simulation results
- Prototype cycle becomes extended for additional debugging
PCB production is HALTED as production fabricator deals with same issue.
Requirements and Capabilities Must Correspond
Verifying the original CAD and Gerber data against the fabricator's design rules and capabilities,
while creating the design and before sending it to production, will prevent many
discrepancies and potential
problems. It will ensure the design intent is preserved and fabrication process flows smoothly. In
addition, Design Rule Checking will prevent:
- Modification of design data by third party
- Replication of problems at other fabrication facilities
- Multiple design iterations and additional costs
The Result
Deploying CAM350 during design would have allowed the customer
to detect discrepancies between their designs and the fabricators abilities, which would have
avoided costly delays.
In Conclusion
Typo recommends CAM350 DRC, DFF, and Netlist Compare to their customers, so these and other problems
can be circumvented during the design stage.
