FPC (Flexible Printed Circuit)

Flexible circuits (also variously referred to around the globe as flex circuits, flexible printed circuit boards, flex print, Flexi-circuits) are members of electronic and interconnection family. They consist of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits. The technology has been used for interconnecting electronic devices since the 1950s in one form or another. It is now one of the most important interconnection technologies in use for the manufacture of many of today’s most advanced electronic products.

In practice, there are many different kinds of flexible circuits, including one metal layer, double-sided, multilayer and rigid-flex circuits. The circuits can be formed by etching metal foil cladding (normally of copper) from polymer bases, plating metal or printing of conductive inks among other processes. Flexible circuits may or may not have components attached. When components are attached, they are considered by some in the industry to be flexible electronic assemblies.

Flexible printed circuits were originally designed as a replacement for traditional wire harnesses. From early applications during World War II to the present, growth and proliferation for flex circuits and flexible printed circuit boards continue exponentially. A flexible circuit in its purest form is a vast array of conductors bonded to a thin dielectric film.

From simple applications to the most complex, the versatility of flex circuits and flexible printed circuit boards is unmatched. Our motto is, “We Go Where Others Will Not..”Flexible Circuit Technologies is happy to take on any flex circuit or flexible printed circuit board design challenge that you bring, including automotive, medical, telecom, industrial or commercial… just to name a few.

Aluminum PCB (Aluminum Printed Circuit Board)

Aluminum Printed Circuit Boards Contain a Thin Layer of Thermally Conductive Dielectric Material that Transfers Heat. There are many names for these products; Aluminum clad, aluminium base, Metal clad printed Circuit Board (MCPCB), Insulated Metal Substrate(IMS or IMPCB), Thermally conductive PCBs, etc… but they all mean the same thing and perform the same way.

FR4

NEMA is the regulating authority for FR-4 and other insulating laminate grades.

Grade designations for glass epoxy laminates are G10, G11, FR4, FR5 and FR6. Of these, FR4 is the grade most widely in use today.G-10, the predecessor to FR-4 lacks FR-4’s self-extinguishing flammability characteristics. Hence, FR-4 has replaced G-10 in most applications.

FR-4 epoxy resin systems typically employ bromine, a halogen, to facilitate flame-resistant properties in FR-4 glass epoxy laminates. Some applications where thermal destruction of the material is a desirable trait will still use G-10 non-flame resistant.
