Introduction:Flex circuits can easily be termed as circuits which are flexible
or can flex. Flexible circuits are basically made from a thin insulating
polymer film with a pattern of conductive traces mounted bonded onto the
substrate. Flex circuits have been in use since the Second World War and
they’re applications are still growing exponentially.Types of Flex Circuits:There are many types of flex circuits and here we will discuss the
major ones1: Single Sided Flex:Single sided flex circuits are the most basic and consist of a
single layer of metal traces on one side of a dielectric layer. The dielectric
can be polyimide or polymer. A polyimide overlay is added for insulation and
protections from environmental degradation.2: Double Sided Flex:A double sided flex circuit has multiple layers on both sides of a
single dielectric layer. The two layers are plated by metalized through holes
to make connections.3: Multi-Layer Flex:Multi-Layer
flex circuits has several copper layers separate...
