What Do You Need Before Sending Files?

Choose the resource that matches your next task: review DFM findings, check BOM risk, prepare files, or answer purchasing questions.

Layout risk

I want to see how DFM issues are reported.

Review a sample report that names the part, location, risk level and recommended action.

View Sample DFM Report BOM risk

I am worried one part will delay the build.

See how lifecycle, stock depth, lead time, compliance and alternates are checked line by line.

View BOM Health Report File readiness

I need to prepare files before requesting a quote.

Use the checklist to organize Gerber, ODB++, BOM, drawings, stack-up, test and packaging notes.

Resource Center FAQ

Short answers for visitors deciding which resource to use first.

What can I use the EBest PCBA Resource Center for?

Use the Resource Center to review sample DFM and BOM findings, prepare project files, and find answers about quoting, sourcing, assembly, inspection, and traceability.

Which resource should I open first?

If you are preparing files, start with the DFM checklist. If you want to understand review quality, open the sample DFM report. If sourcing risk is your concern, open the BOM health report.

Can I use these resources before requesting a quote?

Yes. That is the purpose. The resources help your team prepare better information before asking for a quote or engineering review.

When should I contact EBest PCBA directly?

Contact EBest PCBA when you want your actual Gerber, BOM, drawings or test requirements checked against manufacturing, sourcing and assembly risk.
