Products & Services
Optical and Optoelectronic Assembly Services
Optical assembly and optoelectronic assembly services companies design assemblies and systems for optical and optoelectronic devices.
PCB Design and Layout Services
PCB design and layout services providers generate schematics and CAD files for printed circuit boards.
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
Reflow Ovens
Reflow ovens are used to perform reflow soldering of surface mount electronic components to printed circuit boards (PCB).
Flexible Circuits
Flexible circuits use polyimide films and other foldable substrates to meet the requirements of complex electronic manufacturing applications.
