Quality is an important part of what Protronix offers its customers. We strive to maintain a defect-free manufacturing process while adhering to the latest revision of IPC-A-610, Acceptability of Electronic Assemblies. We conduct a rigorous first piece inspection on every product before we begin the production process. Our high standard greatly reduces errors and the need for costly rework.


Every printed circuit board is run through our Automated Optical Inspection machine before final shipment to the customer. AOI inspects for presence/absence, polarity, misalignment, insufficient solder, solder bridging, lifted leads, through hole, and smt parts as small as 01005. It can read text and through hole resistor color bands. This machine also enables us to constantly improve our process while giving us valuable feed back during production.

    Family owned and operated for over 30 years, Protronix, Inc. is a full-service contract manufacturer specializing in low to medium volume assembly and prototyping.
