Printed circuit board (PCB) mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.Printed circuit boards are used in all but the simplest electronic products. They are also used in some electrical products, such as passive switch boxes.Silkscreen is a layer of ink traces used to identify components, test points, parts of the PCB, warning symbols, logos and marks etc. This silkscreen is usually applied on the component side; however using silkscreen on the solder side is also not uncommon. But this may increase the cost. Essentially a detailed PCB silkscreen can help both the manufacturer and the engineer to locate and identify all the components.
Flexible Printed Circuit Printing
Flexible circuit board is abbreviated as FPC, the circuit layout is made on the flexible substrate by screen printing, as a transmission intermediary for the electronic product signal. Because of continual automated production, increasing wiring density, light weight, small size, reduce wiring error, flexibility and elastically to change shape and so characters, widely applied for consumable electronic products such as LCD screen for notebook, smart phone, tablet PC and hard disc storage device etc. By connecting FPC and motherboard, between LCD screen or various different components to attain signal transmission and foldable cover or rotating and so on function. After the electronic products went to the trend of light weight slim and short, they had a great motivation for the growth of FPC.
