Teledyne EMS builds and tests electronic circuit cards (CCAs) and systems. We do build-to-print work for other companies and generally do not build our own products. Most of the products that we build are high-reliability, J-STD-001 Class 3 and Space (NASA and CS) products. We build everything from SMT CCA, plated thru hole (PTH) CCAs, microelectronic hybrid assemblies to sub-systems that are shipped completely tested for customer installation into aircraft, missiles, or other equipment. Most work at Teledyne EMS is low-volume/high-mix with volumes from one-time builds of 10 units to monthly shipments of 250 units or more.
