Etched Hexagonal Shielding Mesh is used for shielding electronics from EMI and protecting vents and windows with ultra-thin etched hexagonal mesh that keeps 80–90 % open area for airflow and visibility. Photo-chemical machining to drawing (ISO 2768-f) is the reference cited for it on drawings, datasheets and purchase orders.
What Photo-chemical machining to drawing (ISO 2768-f) Means for Etched Hexagonal Shielding Mesh
The dimensions in the table below are supplied to suit Photo-chemical machining to drawing (ISO 2768-f). Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
Etched Hexagonal Shielding Mesh Dimensions
| Size | Hole diameter (mm) | Pitch (mm) | Thickness (mm) | Open area (%) | Material |
|---|---|---|---|---|---|
| Hex 0.5 / bar 0.05 | 0.50 | 0.55 | 0.05 | 83 | Copper |
| Hex 1.0 / bar 0.08 | 1.00 | 1.08 | 0.08 | 86 | Nickel silver |
| Hex 2.0 / bar 0.10 | 2.00 | 2.10 | 0.10 | 90 | SS304 |
Specifying Etched Hexagonal Shielding Mesh Beyond the Standard
- Cell size & bar width: Smaller cells shield higher frequencies; thin bars keep open area high.
- Material: Copper or nickel silver for conductivity; SS304 for strength.
- Plating: Tin or nickel plating for solderability and corrosion protection.
When Etched Hexagonal Shielding Mesh Is Not the Right Choice
Not a structural or impact-resistant panel.
