What is difference between PWB and PCB?

## What is the difference between PWB and PCB?

1. **What is a PWB?** .

A Printed Wiring Board (PWB) is a board used to hold electronic components, usually made of non-conductive material with conductive pathways etched or printed on it.

2. **What is a PCB?** .

A Printed Circuit Board (PCB) is similar to a PWB but refers specifically to a board with conductive pathways created by printing a conductive material like copper onto the board.

3. **Difference between PWB and PCB** .

The main difference between a PWB and a PCB lies in the method used to create the conductive pathways on the board. In a PWB, these pathways are typically etched into the board or created using other methods like wire wrapping. On the other hand, a PCB features conductive pathways that are printed onto the board using a conductive material such as copper.

4. **Advantages of PCB over PWB** .

PCBs offer several advantages over traditional PWBs. PCBs allow for more precise and complex circuitry due to the ability to create highly detailed pathways through the printing process. PCBs also tend to be more cost-effective in mass production compared to PWBs. Additionally, PCBs are generally more reliable and durable due to the uniformity and consistency of the printing process.

5. **Usage of PWB and PCB** .

While both PWBs and PCBs are used in electronic devices, PCBs have become more common due to their advantages. PCBs are used in a wide range of electronics, from consumer products like smartphones and computers to industrial equipment and aerospace systems. PWBs are still used in certain applications where a simpler design is sufficient or where cost is a major factor.

In conclusion, the difference between a PWB and a PCB lies in the method used to create the conductive pathways on the board. PCBs offer various advantages over PWBs, leading to their widespread use in electronic devices today.
