Products & Services
Optical and Optoelectronic Assembly Services
Optical assembly and optoelectronic assembly services companies design assemblies and systems for optical and optoelectronic devices.
Flexible Circuits
Flexible circuits use polyimide films and other foldable substrates to meet the requirements of complex electronic manufacturing applications.
Printed Circuit Substrate Materials (PCB / PWB)
Printed circuit materials have copper-clad surfaces for the fabrication of electronic and electrical circuitry on printed circuit boards (PCBs), printed wiring boards (PWB) and flexible circuits. They include materials for flexible film circuit and membrane switches, as well as rigid laminates for circuit boards
Electrical and Electromechanical Assembly Services
Electrical and electromechanical assembly services provide board-level assembly, chassis and rack panel wiring, and front panel assembly. Typically, suppliers provide the complete turnkey production of electronic and electromechanical finished products from procurement through final assembly with testing and burn-in, if required.
Professional Certification Programs
Professional certification programs prepare clients for certification testing, or provide training that ends with certification.
