Flexible Printed Circuit Board

Flexible circuit interconnections give many advantages over discrete wiring, saving in space, weight, labour and inventory, all adding to cost reduction and ease of product assembly. At LT Circuit we manufacture single, double sided, flex-rigid multilayer combinations, PTFE, Polyimide Glass, Flexible Heaters, Silver Epoxy, etc. Our emphasis on Quality and Service has led us into every application across a huge range of markets in all areas of industry including Aerospace, Automotive, Medical, Military, etc.


All our products can be made with a combination of stiffened areas in rigid or polyimide, plated or unplated with various finishes such as Silver, Gold, Passivation etc. We mainly use Copper and Polyimide.

Double sided flexible circuit (FPC) consists of double-sided copper clad material with top and bottom cover films (PI or Green/Yellow Oil, Carbon Ink, etc).  Two 

conductive layers with an insulating layer between, plus conver layers on outer layer. The cover films are pre-routed to access copper from both sides using plated thru 

holes(PTH).
