MES production traceability
Know What Went Into Your Build — and How It Was Controlled
EBest PCBA uses MES production records to connect the released work order, material identification, production steps and available quality records. Tell us what you need to trace before quotation so the required identifiers and records can be included in the approved production route.

Follow the Build From Released Files to Shipment
MES records help the project team verify which approved order was built, which identified materials entered production and which recorded steps were completed. The exact coverage depends on the identifiers, equipment connections and reports agreed for your order.
Material & IQC
Required supplier, lot, date-code or UID information is recorded where specified.
Material Issue
Identified material is issued against the applicable work order and route.
Production & Inspection
Recorded station status and available inspection data follow the approved route.
Product SN & Shipment
Finished-product identifiers and agreed shipment records close the build history.
Bidirectional traceability
Start With a Material UID or a Finished-Product Serial Number
When UID and SN capture are included in the approved production route, the production team can follow the material forward into the related build or follow a finished product back to the recorded materials and process history.
Two practical lookup directions
Use forward traceability to identify where a controlled material was used. Use reverse traceability to review what recorded materials and process steps are linked to a finished unit.
Project boundary: complete UID-to-SN coverage is not assumed for every order. Required identifiers, scan points, connected inspection data, record format and retention period must be agreed before production.

Choose the Records Your Team Needs to Review
Tell us which records support your receiving inspection, supplier approval, repeat order or field investigation. We will confirm what is standard, what depends on the selected route and what requires a project-specific agreement.

Use the Record That Answers the Quality Question
A traceability system is useful only when it helps your team identify the affected order, material, process or finished unit. We match the requested evidence to the risk and acceptance requirement defined for the project.
| Customer question | Control point | Relevant record |
|---|---|---|
| Was the correct revision built? | Released production baseline | Work order and approved file revision |
| Which material entered this build? | Incoming identification and issue | Specified supplier, lot, date code or material UID |
| Were required steps completed? | Approved route and station status | Recorded process-station history |
| How were solder joints inspected? | Inspection method included for the build | Available SPI, AOI or X-ray record |
| Which finished units may be affected? | UID/SN linkage where included | Affected material UID, work order and product SN range |
| Was the corrective action verified? | Nonconformance disposition and recheck | Issue, action, verification and release record |
Nonconformance trace path
Contain the Issue Before Affected Material Moves Forward
When a recorded requirement is not met, the team identifies and contains the affected material or product, traces the related identifiers, reviews the impact and verifies the agreed action before release.
Identify and Contain
Stop affected material or products from continuing unchecked.
Trace the Affected Identifiers
Review the linked UID, work order, station history or product SN available for the project.
Review and Agree the Action
Assess the impact and obtain the required disposition for correction, rework or replacement.
Recheck and Release
Verify the completed action and retain the applicable record before release.
Set the traceability scope before quotation
Tell Us What Your Team Must Be Able to Trace
Send the Gerber or ODB++, BOM, drawings, required identifiers, inspection and test requirements, record format and retention period. We will review the requested scope, identify missing inputs and confirm the available records for your production route.
Frequently asked questions
MES Traceability FAQs
Direct answers about UID, serial-number, material, production and quality records.
Does EBest PCBA use MES for production traceability?
Yes. EBest PCBA uses MES production records to connect work orders, identified materials, recorded process steps and available quality information. The exact data coverage is confirmed for each project before production.
Can EBest trace a material UID to finished-product serial numbers?
Yes, when material UID and finished-product SN capture are included in the approved production route. We confirm the required scan points and lookup scope before production.
Can a finished-product SN be traced back to material lots?
Yes, when the relevant material identification and SN linkage are included for the project. Send your required lot, date-code and serial-number rules before quotation.
Does every order include complete UID-to-SN traceability?
No. Traceability depth depends on the identifiers, scan points, route, connected data and reports agreed for the order. We confirm the included scope in the project review and quotation.
Are SPI, AOI, X-ray and test results stored in MES?
Available inspection and test data can be linked where the method and equipment integration apply to the approved route. We confirm which results and reports are available before production.
Can traceability records be supplied with the shipment?
Yes, when the required records, format and delivery timing are agreed before quotation. The quotation or project documents will identify the records included.
How long are production and quality records retained?
The applicable retention period is confirmed by project and record type. Tell us your required period before quotation so we can verify availability and include it in the agreed scope.
What should we send before quotation?
Send the available Gerber or ODB++, BOM, assembly drawings, test requirements, acceptance criteria, required UID or SN rules, report format and retention period. We will identify missing inputs before confirming the traceability route.
