Different structures of the PCB board have different functions
- Release on:2017-05-05
A PCB is especially of two sorts. The first is the through-hole PCB where skin pores are punched in around the nodes where the component lead goes overall and they are soldered about the opposite side. It is an old technology yet still used for cheap circuitry applications. The next use of these boards is always to support extremely bulky components like transformers as well as rating capacitors.
Another kind of PCB will be the onboard SMD PCB or surface mounted device PCB. No have holes instead it's small conducting beds the location where the tiny SMD components are positioned and soldered using special equipments. It's got higher mechanical strength and either side can be used for components because there are no holes. Also as the SMD are very tiny that this circuits can be miniaturized.Specific information, you can contact a professional Printed circuit board company, you can get more information about the PCB board.
