Optical Assembly Build Traveler Template
A traveler follows the work through assembly so every step, tool and component lot is recorded. This template covers a typical optical or laser module build with a cleanroom context, alignment, cure and test steps.

Sign-off
Replace the operations with the steps from your approved routing. Keep the traveler revision under document control and make sure the operations match the ERP or MES routing for the same assembly revision.

How to use the traveler
Enter the work order, assembly revision and serial number, then list the operations from your approved routing. Print the traveler and have each operator initial and date each step. Record component lot numbers in the traceability table so that any customer return can be linked to the exact adhesive, optics and source used.
- One traveler per serial number or lot
- Initial each step when complete
- Record adhesive lot and cure data
- Attach alignment and test data sheets
Why traceability matters in photonics
Small differences in an adhesive lot, a coating batch or a laser diode can change module performance. A traveler lets quality isolate the variable without opening every unit. For regulated or defense customers, build records are often a contractual requirement and may be retained for years.
Keeping the traveler in sync with your ERP
Many shops keep the routing in the ERP and print a separate traveler that drifts out of date. Match operation numbers and descriptions to the ERP routing so the paper record and the system record agree. If you use an MES, treat this document as the template for electronic build records.
Frequently Asked Questions
Is this a device history record?
It can serve as the core of one. A full device history record usually adds test data, nonconformance records and final acceptance, depending on your quality system and customer requirements.
Can I add more operations?
Yes. Export to Word or Excel and add rows for as many operations as your routing needs, such as fiber splicing, burn-in or environmental screening.
Who should sign each step?
The person who performed the operation should initial and date it. Critical steps such as alignment or final test often need a second sign-off from a lead or inspector.
Does it need a cleanroom?
Not necessarily. Choose the assembly area that matches your process. Optical assemblies sensitive to particulates commonly run in ISO 7 or cleaner areas or at laminar flow benches.
If your travelers drift from your ERP routing, Netray can help connect routing, lots and test data so records are generated rather than retyped.
