To err is human, but that doesn’t ease the pain when the assembly house calls with news that a component can’t be placed because its package footprint is different than what is depicted within the Gerber files. Many companies today have in-house CAD software allowing their engineers to design and produce Gerber files for PCB fabrication. The vast majority of PCB layout designs are error free and assembly with fabricated PCBs is successful without incident. It is those occasional times when a BOM part number change introduces a different footprint and the Gerber files are not updated when issues arise. The outcome can be a simple assembly rework forcing a fit, but it can also end in requiring another PCB fab re-spin . . . a more costly outcome.
NPI can help you avoid such unexpected cost impacts with our newest CAD service offering, “footprint-package confirmation.” NPI’s experienced CAD team will carefully review your Gerber files comparing its data against BOM component footprints to confirm a layout match exists. Pricing is based on the level of layout review requested ranging from basic footprint confirmation to detailed IPC-7351B spec conformance. NPI’s goal is to provide customers the upmost confidence that footprint mismatch issues are a thing of the past. Call NPI today . . . you bring challenges, we bring solutions!
