FAQs about Five new traces and new PCBs, plus one bonus project and two … Coupon?

Which traces should be used for high-current PCBs?

Straight traces are preferable for carrying high current. However, in practice, traces may need to curve or have vias connecting different layers. Minimizing sharp corners and avoiding narrow neck-down sections helps reduce resistance and improves current flow. 4. Optimizing Trace Spacing for High-Current PCBs ...

Why do PCBs need plated-through vias?

By stacking several traces on different layers and connecting them via plated-through vias, the effective trace width increases, allowing the PCB to handle more current. When high current needs to flow between different layers of the PCB, vias must be designed with current capacity in mind. ...

Should PCB traces be wider?

As long as you obey the 'design rules' of your pcb supplier, you can do whatever you like with pcb trace width and not worry about 'etching problems'. It's entirely normal to reduce the width of traces where space is limited. It's sometimes called 'necking'. Remember that power traces usually need to be wider than others. ...

How to optimize PCB design for high-current applications?

Beyond simply calculating trace width and spacing, there are several techniques you can use to optimize PCB design for high-current applications. One effective way to manage high currents is to use multiple PCB layers for current conduction. ...

Why do we use copper traces on PCBs?

Using copper pours or large copper areas on internal or external layers can significantly enhance current-carrying capacity. This method allows designers to manage high current without needing excessively wide traces, which can be impractical in some PCB layouts. ...

How do traces affect a PCB stack-up?

The position of the trace in the PCB stack-up can affect the amount of current it can safely carry. For example, traces on external layers have better cooling (due to exposure to air), whereas internal traces are more insulated and can retain heat, requiring wider traces. ...
