What Is Bare PCB and What Are Its Advantages

Jan. 28, 2022

A bare PCB is a printed circuit board without solder resist layers, it has only one or two circuit layers so PCB designers can cut or solder copper traces to test their designs. Printed plate manufacturer TOPFAST explains what it is used for and what we can do for you.

What is a bare PCB

To understand bare PCB, you should know the difference between bare PCB and bare PCB.

A bare PCB is an incomplete circuit board with no solder resist covering the copper traces, and a bare PCB is a complete circuit board with no mounted components. Depending on the need, you can print on bare PCB with or without screen printing. And bare PCBs also have PCB pads.

After generating the electrical traces on the PCB core or laminate, the surface finish (e.g. OSP, ENIG) is applied to the PCB pads and then screen printed on the laminate material.


When to use bare PCB

In our experience, the demand for bare PCBs is not that great. Customers who order bare PCBs have not yet defined their project design and they use bare PCBs to test their design on the board.

The copper traces of the bare PCB are exposed and engineers can easily cut and solder the traces. After the engineers have finalized their project design, they can contact us to fabricate and assemble the PCBs.

The use of bare PCBs still occurs during the project development phase, when the PCB design is almost complete.

Benefits

Bare PCBs allow for more complex circuit designs at a lower cost.

Unlike design testing of PCB prototypes, there are no solder resist layers on bare PCBs and it is easy to cut or solder copper wires. And bare PCBs are far less expensive to manufacture than PCB prototypes.

Bare PCBs are printed circuit boards, while breadboards are not. The effect of circuit testing on them is different, and bare PCBs to a large extent perform almost identically to the final product.

Modifying and testing your design with bare PCBs provides more assurance for the final product. Bare PCBs are easy to debug, and using them to modify your design before PCB manufacturing can avoid possible financial losses.
