Two-component supply creates two traceability paths. A purchasing and production record should show which components were used together and whether their handling remained within the current supplier instructions.
Evaluation scope
JY-9285LS is listed as an A/B thermally conductive adhesive liquid silicone. Qualification must identify both components and the current supplier processing instructions. Do not infer a mixing ratio from the A/B label or transfer settings from another silicone grade; the cured bond and the assembled device need their own acceptance checks.

Keep these variables in the record
| Item | What to record |
|---|---|
| Components | Trace both supplied lots and their approved pairing. |
| Metering | Use the confirmed ratio basis and equipment method. |
| Joint | Control coverage, thickness and substrate condition. |
| Cure | Verify the actual joint under the agreed process. |
Trial and review plan
- At receipt, compare component identities, lot numbers and date information with the purchase order and supplier documents. Resolve mismatches before material is released.
- Record storage and opening history for both components. Keep the production issue record linked to the assemblies made from each approved pairing.
- Define supplier-approved checks and disposition for material with unclear history. Do not blend old and new components to conceal an expiry or traceability problem.
How to use the results
A current date on one container does not qualify the other component. Likewise, a successful small test does not automatically extend a supplier's shelf-life statement. Agree a documented disposition process with quality and the supplier.
Information to include in an RFQ
Provide the electronic component, substrates, joint dimensions and dispensing arrangement. Request current ratio, handling and cure guidance together with technical and safety data. Ask which material properties are grade-certified and which thermal or mechanical results must be established on your assembly.
Frequently asked questions
Can components from different deliveries be paired automatically?
Only where the supplier's grade instructions and your quality procedure allow it. Verify compatibility, identity and condition, and record the actual pairing used in production.
Are these proposed checks certified results for this grade?
No. This article describes evaluation and procurement questions, not completed customer trials. Request current grade-specific documents and appropriate test evidence. The acceptance criteria must fit the actual formulation, process or assembly being qualified.
