hello@yourpcb.comInclude the job you need to complete, the inputs you already have, the units you expect, and any formulas or standards you want the tool to follow. That context helps us prioritize requests that solve real PCB design or manufacturing problems.
Yes. If a calculator output, unit conversion, or explanatory paragraph looks wrong, send the page URL, your test values, the expected result, and the reference you used. Reproducible examples let us verify and fix issues faster.
Yes. Many messages are about PCB stackups, trace current limits, assembly documentation, Gerber review, and practical manufacturability tradeoffs. We can use that feedback to improve both the tools and the supporting reference content.
We review messages in batches. Time-sensitive bug reports with clear reproduction steps are easier to evaluate quickly than broad feature requests without technical detail.
External references help us align calculators and educational content with widely recognized definitions, process terminology, and quality frameworks used across electronics engineering and manufacturing.
A PCB calculator is a software tool that converts an engineering rule, process limit, or physical model into a practical result that designers can use during layout, review, and quoting. A PCB reference page refers to explanatory content that defines common manufacturing terms, units, materials, and quality checkpoints so users can understand how a calculation should be applied in real production work.
Messages sent through this page often bridge the gap between an ideal formula and a real-world manufacturing decision. That is why it helps to mention whether your question is about trace current, copper thickness, thermal behavior, fabrication notes, assembly constraints, or drawing interpretation. The more precise the context, the easier it is to connect your question to the right tool or content update.
| Contact Reason | Useful Details | Best Supporting Evidence |
|---|---|---|
| Bug Report | Page URL, inputs, output, browser | Screenshot or reproduction steps |
| Tool Request | Problem statement and needed units | Formula, datasheet, or standard |
| Engineering Question | Board stackup, material, load case | Drawing, Gerber note, or process spec |
| Content Feedback | Ambiguous wording or missing context | Reference link showing the preferred wording |
When users report a mismatch, we usually compare the page against common public definitions and quality frameworks before deciding whether to revise the copy or the calculation logic.
