Cosmotronic has been an industry leader in providing our diverse customer base with leading edge PCBs for nearly 45 years.

High Reliability Rigid Boards

High Reliability Flexible Circuits

High Reliability Rigid Flex

Today we specialize in fabricating all types of Rigid, Rigid-Flex and Flexible Circuits that meet the toughest commercial, military and aerospace applications.

Our capabilities include:

Bookbinder Circuits
Controlled Impedance
High frequency Applications
Heavy Metals
Heat Sinks and Metal Cores
Blind and Buried Vias
Micro Vias - Epoxy or Copper Filled
Multiple Surface Finishes
A Wide Range of Substrate Materials

Panel sizes up to 18x24" are typically used, however, we can go with larger panel sizes for special applications. We can meet your circuit requirements regardless if it's a one layer design or requires 30 layers. We routinely work to the requirements of IPC-6013 class 3 for high reliability commercial and military/aerospace flexible circuit applications, as well as, IPC-6012 Class 3, and 3A for the most stringent rigid PCB needs. Cosmotronic is qualified to certify boards to military specifications MIL-PRF-31032, MIL-P-50884, and MIL-PRF-55110

Our products are prepared for production by some of the industries most experienced CAM operators, utilizing the Valor Genesis CAM software developed by Orbotech(r). The Cosmotronic Engineering department routinely reviews jobs for circuit producibility as it relates to Design for Manufacturability (DFM) and will provide inputs and suggestion if issues or opportunities arise.

Cosmotronic is equipped with the resources that can respond to your wide range of technical challenges. Please feel free to contact us if you would like us to provide your organization with a 'Lunch and Learn' meeting to discuss a variety of board design challenges or any other technical discussion that meet your needs.
