The Difference between PCB and PWB

Hits:-   Issuing time:2019-03-11

  In our daily life, we often use electronic products. A lot of electronic components are used in each electronic product, so we often hear the words PCB and PWB. They are similar but different from the literal point of view, therefore many people are confused. They are not clear whether the PCB and the PWB are the same. Let's explain in detail.

  The difference between PCB and PWB:


  PCB: Based on insulating substrate, it means a kind of products on which the wires are connected and components are printed from point to point on a dielectric substrate in a predetermined design. It is the English abbreviation of Printed Circuit Board.

  PWB:Based on insulating substrate, it means a kind of products on which the wires are connected from point to point on a dielectric substrate in a predetermined design. However, there is no printed component on it.PWBs are the early name of the British, because at that time there were only circuit diagrams on the circuit board, but no printed components. So they belonged to the more primitive board. Under its effect, now many traditional British and some Hong Kong people still call the circuit board to be PWB, which is the English abbreviation of Printed Wire Board.

  In general, the PCBs are the boards already equiped with various components, however the PWB is just a designed substrate with no components. It can be seen from this that the difference between them is quite obvious.

  In addition, when we search for the keyword “PCB” on the Internet, it is also automatically matched the “PWB”. In the encyclopedia of the circuit board, its name is: PCB, PWB, aluminum PCB, high frequency PCB, thick copper PCB, etc. It can be seen that the PWB is already contained in the PCB. But from a substantive point of view, they are also the same product. So no matter in the industry or outside, both titles are ok.

  In fact, this lies in the usual habits of local people. Before we go deeper, we must have doubts about the PCB and the PWB. Therefore, it is still necessary to understand the difference between the two after a detailed understanding.
