Frequently asked questions

Questions About These Project Cases

Are these customer projects?
No, not all of them. The PCB design examples are documented in the EBest company profile. Other examples are identified as representative manufacturing scopes based on services already published by EBest PCBA; no unverified customer, yield, cost or field-performance claim is added.
Why are customer names not displayed?
Customer identities, product files and confidential program information are not published without permission. The page focuses on project type, manufacturing scope and engineering controls that can be discussed without exposing customer data.
Can I request details about a similar project?
Yes. Send the board type, application, quantity, current project stage and the technical concern you want reviewed. EBest PCBA will confirm which published capability or representative route is relevant to your project.
What files should I send for project review?
Send the information currently available, such as schematic, Gerber or ODB++, BOM, pick-and-place data, mechanical drawings, test requirements, quantity and delivery target. Incomplete files can be used for the first discussion.
Can EBest PCBA sign an NDA before I send files?
Yes. Request a mutual NDA before sharing confidential design, sourcing, assembly or finished-product information.
