Double Sided Flexible PCBs With Immersion Gold
Types of Flex Circuits:
There are many types of flex circuits and here we will discuss the major ones
1: 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 separated by dielectric layers. The metal layers are again connected by through holes. There are more complex interconnections, layer design surface mounting.
4: Rigid Flex Circuits: In rigid flex circuits the circuits consists of multiple circuit layers connected by an epoxy pre-preg bonding film, almost like a multi-layer flex circuit. Flex circuits are almost a combination of rigid circuit boards and flex circuits. Rigid flex circuits have higher component density.
