More Information

Lead Free ROHS compliant PCB assembly services have been part of our capabilities for years and our long history in electronics manufacturing accounts for the exceptional quality and high yields our customers experience every day with this newer technology. Our attention to detail along with unsurpassed customer service explains why our customers keep coming back to us job after job.

In addition to Lead Free processing we also offer high quality SnPb solder solutions for products not required to meet ROHS specifications. To make your product more producible we offer design for manufacturing (DFM) reviews during the PCB artwork creation phase, or prior to artwork release to your PCB manufacturer. This review is especially important to avoid common problems in Lead Free assembly.

We also offer custom cable assembly, including military circular connectors, Ethernet, BNC and DB styles of connectors. Single wire to complex bundles encased in shrink tubing.
