RoHS Compliant Manufacturing

“RoHS”, the “restriction on the use of certain hazardous substances in electrical and electronic equipment”[1], is a European Union initiative design to significantly decrease the usage and consumption of certain hazardous materials.

As a world-wide manufacturer and distributor, Kokomo Electronic Assembly complies with increasingly stringent waste and recycling regulations. As a subsidiary resource for General Motors, Kokomo Operations was the first GM Components Holdings, LLC site to achieve “Zero Landfill Status”. Kokomo Electronic Assembly has introduced a variety of RoHS-compatible products and processes as this requirement becomes more common in today’s industries.

We have developed the following RoHS compliant materials and error prevention processes:

MATERIALS
Currently, all of the products that Kokomo Electronic Assembly produces are free of the following:

  • Mercury (Hg)
  • Cadmium (Cd)
  • Hexavalent chromium (Cr6+)
  • Polybrominated biphenyls (PBB)
  • Polybrominated diphenyl ether (PBDE)

Many of the products Kokomo Electronic Assembly produces are free of the following:

  • Pb solder paste (flip chips, sensors)

ERROR PROOFING
In order to verify proper usage and assembly, Kokomo Electronic Assembly utilizes a Factory Verification System (FVS, refer to “Error Prevention and Detection Systems” for further details). Specifically, a FVS continuously verifies that an operator has installed the proper material (e.g., solder paste, surface mount component, etc.) and loaded the correct program (e.g., reflow profile). Otherwise, FVS electronically blocks the upstream “Machine Not Busy” signal and prevents product movement. FVS helps maintain Kokomo Electronic Assembly’s standards for RoHS compliance.
