How Buyers Should Review Dissipative Coatings on Packs

Dissipative coatings are surface treatments applied to packaging or fixtures to help manage charge; buyers should define target range ownership, abrasion and rework limits, and which trays or boxes carry the coating before comparing offers. Use it to compare coated surfaces with inherently conductive polymer packs. It is a checklist for electronics buyers – not sizing or approval for dissipative-coatings-packaging-surfaces.

Part 1. What Problem Do Dissipative Coatings Try to Solve?

Coatings can add surface control to fixtures or packs when bulk conductive polymers are not chosen. Name the part family and wear environment.

Readers searching for dissipative coatings usually need a project checklist, not a catalog slogan.

Part 2. Which Target Range Ownership Fields Belong in the RFQ?

State who owns the acceptable surface range and which method verifies lots. Avoid inventing numeric setpoints in blog language.

Part 3. How Should Abrasion, Solvent, and Rework Limits Appear?

Coatings can wear. Ask for abrasion expectations, approved cleaners, and when a coated surface must be retired.

Important: Do not accept a coating claim from a color chip. Attach range ownership, abrasion notes, and polymer alternatives before comparing prices. (Source: IEC 61340 surface practice / site acceptance methods.)

Part 4. When Should Buyers Prefer Bulk Conductive Polymers Instead?

If wear is high or coating adhesion is unreliable, compare conductive PP boxes and trays as alternatives.

Part 5. Which Traceability Fields Keep Coated Lots Honest?

Require lot IDs linking coating batches to tray or box serials used on the line.

Part 6. Which Sanwei Routes Support Coating Reviews?

Sanwei routes boxes, trays, and bins for material comparisons while coating process details stay with the coating owner.

• Boîte ESD – box route when coated or conductive surfaces are compared.
• Plateau ESD – tray route for coated staging surfaces.
• Boîte de composants ESD – bin route for small-lot coated interiors.

Bring the RFQ notes to the Sanwei ESD box and packaging range discussion, or contact Sanwei with drawings and acceptance owners.

Why not: Do not treat a paint color chip as a dissipative coating package without target range ownership and abrasion notes.

Part 7. What Are the Fit Boundaries?

This guide explains RFQ language for dissipative coatings on packaging surfaces. It does not certify coating processes or set ohm limits.

FAQ

What are dissipative coatings on packs?

They are surface treatments intended to help manage charge on packaging or fixture surfaces.

Which fields belong on the RFQ?

Target range ownership, abrasion and cleaner limits, rework rules, and polymer alternatives.

When should buyers avoid coatings?

When wear is high or adhesion cannot be controlled on the chosen substrate.

Do coatings replace conductive boxes?

Not automatically. Compare bulk conductive polymers when coating life is short.

How should lots be traced?

Link coating batches to the tray or box IDs used in production.

Which Sanwei products help the review?

ESD boxes, trays, and bins support material comparisons while coating details stay with the process owner.

Does this page certify coatings?

No. Certification and acceptance belong to verified methods and responsible engineers.
