Company Specialties

Multilayers



Graphic Research, Inc. produces interconnect products with full compliance to commercial, and military standards. The range of products is up to 32 layers with fine line densities, blind and buried vias, metal, cores, and external heat sinks.



Graphic Research's multilayer printed wiring boards are used extensively by customers in computer applications, telecommunications, the medical field, instrumentation, and military programs.



We also manufacture fine line multilayer designs to accommodate multi-chip-module (MCM), chip-on-board (COB) and thin core PCMCIA substrates on materials such as epoxy glass, polyimide, Kevlar®, flexible composites and other high Tg materials.

 

Flex and Rigid Flex



Graphic Research has been and continues to be, the leader in flex and rigid flex technology since 1976. This technology, originally pioneered in Aerospace, is now being applied to Commercial applications. Flex circuit technology allows the user to increase package density and eliminates the use and assembly of wiring harnesses. Multilayer flex and rigid flex circuits, adhesive and adhesive-less, may contain many layers of Kapton®, acrylic and modified epoxy bonded together in one or more sequential lamination cycles. Reliable plated thru holes make the interconnection from layer to layer providing a highly dependable end-product.

 

Metal Core



Graphic Research has been expanding its technology base in metal core printed wiring boards since 1975 and is regarded as an industry leader in this special application where heat dissipation requirements necessitate a deviation from standard construction.



We are currently producing, in volume, products which contain active and inactive cores of aluminum, copper, and copper/invar/copper with a host of variations to the number of layers and thickness of metal cores.

 

Teflon® Multilayers



Graphic Research is currently manufacturing multilayer Teflon® type boards reinforced with ceramic, woven /non woven glass for microwave and high frequency applications. We are also fabricating multilayer boards into a woven glass/ ceramic filled thermoset material that will provide high frequency performance comparable to PTFE substrates.
