Copper Clad Laminates. If you first time to learn flexible printed circuit board, you may feel confused about it. Why flex PCB board can so provide the flexible ability for electronic products? This post will from the Copper Clad Laminates point to discuss this issue. Copper-clad laminates are used in the electronic components of a wide range of electronic equipment, such as PCs and mobile terminals. Components made using copper-clad laminates include printed wiring boards and semiconductor packages. The process of creating copper-clad laminates begins with glass cloth made from glass fiber. The glass cloth is impregnated with a varnish made primarily from epoxy or other resins, and is then coated in copper foil on both sides. In fact, the application of Copper Clad Laminates has wide range used. For example, smart phones or devices were all need use this material. Because Copper Clad Laminates, were mine as material of flexible circuit boards, and FPC also the main PCB components for ...

What is Copper Clad Laminate? Copper Clad Laminate, abbreviated to CCL, is a type of basic product of PCBs. With glass fiber or solid wood pulp paper as reinforcing product, a CCL is a type of product through lamination with copper clad on each one side or both sides of reinforcing product after getting soaked in resin. How are CCLs Classified? According to various classification requirements, CCLs can be classified into different categories: • Based on CCL mechanised rigidity, we've inflexible CCL (FR-4, CEM-1, etc.) and flex CCL. Inflexible PCBs be determined by inflexible CCLs while flex PCBs are on flex CCLs (flex-rigid PCBs are on both inflexible CCLs and flex CCLs).        • Based on insulation product and set ups, we have natural resin CCL (FR-4, CEM-3, etc.), metal-base CCL, ceramic-base CCL etc. • Based on CCL thickness, we've standard width CCL and thin CCL. The previous one requires at least 0.5mm width while the latter can be thinner than 0.5mm. Copp...
