Definitions and References

A wire harness is an organized bundle of wires, terminals, and protective coverings used to route power and signals through equipment. Cable assembly refers to prepared and terminated cables used for a specific interconnect purpose, and those definitions matter because PCB calculators often sit upstream of real connector and harness decisions.

Frequently Asked Questions

Which calculator should I open first?

Start with the trace width calculator when current and copper heating are the main constraint, then move to impedance, creepage, or via tools as the layout problem becomes more specific.

Are these calculators based on recognized standards?

The trace-width tool implements an IPC-2221 power-law estimate. Numeric clearance/creepage, differential impedance and embedded microstrip results are unavailable pending validation.

Can one calculator replace a full stackup review?

No. The tools accelerate estimation, but controlled impedance and manufacturing decisions still need your actual laminate, copper, and fabricator limits.

Why are wire harness and cable assembly definitions relevant here?

Many boards connect into larger electromechanical products, so PCB routing decisions often influence connector, cable assembly, and harness choices.

Do the tools support both current and signal-integrity problems?

The toolkit includes current capacity, isolated-line impedance and panelization estimates. Clearance/creepage is a design-condition checklist; differential calculation is unavailable.
