The most common printed circuit board has wiring on one side, and components on the other side. As the wiring is available only on one side of the insulating substrate, this type of printed circuit board is also known as single side printed circuit board.
Single-sided copper clad laminate- cutting – image transfer by photochemical processing or screen printing – removing corrosion resistant ink – washing and drying – hole drilling- shape processing – cleaning and drying – printing solder mask- curing – printing mark symbol – curing – cleaning and drying – pre-coating flux – drying-finished product
The single side printed circuit board mainly uses the phenole copper clad laminate or cotton paper and epoxy copper clad laminate as its substrate. Due to the low price and high quality, single side printed circuit board is widely used to mechanically support and electrically connect electronic components, and can be commonly found in radios, heaters, refrigerators, washing machines, printers, vending machines, and other commercially produced electronic devices.
Since there are so many companies around the world that provide PCB services, PCB assembly China remain very competitive with pricing while maintaining a high quality standard. Companies that offer PCB assembly China uses advanced technology machines and equipment for surface mount technology, SMT assembly, solder paste stencils, electronic board testing and integration, through hole PCB, lead-free reflow oven, DIP wave soldering, and lead-free wave soldering.
