Project inquiry and engineering review

Send Your PCB or PCBA Project for Engineering Review

Share the files you have and identify the questions you do not. EBest PCBA routes PCB fabrication, component sourcing, assembly, testing and box-build requirements through one review path before quotation.

You can start with partial files. Missing inputs and open questions are identified during review.

Contact FAQ

Before You Send Project Files

These answers clarify how to begin without creating an unverified upload or security promise.

What files should I send for a PCB fabrication quotation?
Send the available Gerber or ODB++ data, drill files, fabrication drawing, stack-up or material requirements, board thickness, copper weight, surface finish, impedance notes, quantity and delivery destination. If an item is unknown, mark it as open rather than delaying the first contact.
Can I contact EBest PCBA before all project files are complete?
Yes. Email the files and information currently available, then list the missing documents and unresolved decisions. EBest PCBA can identify which inputs are required before a quotation or production release can be confirmed.
Can I request an NDA before sharing drawings or manufacturing data?
Yes. Use the NDA request link and provide your company name, contact information and a short description of the project type. Do not send sensitive files until the confidentiality route is agreed.
How should I send a large or sensitive file package?
Email the project summary and file-package description first. Ask EBest PCBA to confirm the appropriate transfer route for the package before sending confidential or unusually large data. This static page does not claim to provide a direct upload service.
Can EBest PCBA quote PCB fabrication without assembly?
Yes. Use the PCB fabrication route and provide the board data, construction requirements, quantity and delivery information. Assembly files are not required when the requested scope is bare-board fabrication only.
Can the same inquiry include PCB fabrication, sourcing and PCBA assembly?
Yes. Use the turnkey PCBA route and include the PCB data, BOM, centroid file, assembly drawing, DNP notes, test requirements, quantity and destination. The quotation will be based on the released project scope and reviewed files.
What happens after EBest PCBA receives my inquiry?
The request is routed by project type, available inputs and open questions are checked, and the relevant construction, sourcing, assembly, inspection, testing and delivery requirements are reviewed before the next action or quotation scope is confirmed.
How do I request supplier qualification or compliance information?
Email the supplier questionnaire or list the documents required by your approval process. The applicable legal entity, site, certification scope, validity and project evidence must be confirmed before a customer relies on them.
