Shielding Material Programme

Foil Braid Wire And Drain Wire Matched To One Construction

The Programme

What This Covers

A shield is a system, not a component. The tape, the braid wire, the drain wire and the overlap all decide the final attenuation together, and changing one without the others is how shielding specifications quietly fail. This programme fixes all four against a single construction so repeat orders behave the same way.

Step By Step

How It Runs From Enquiry To Delivery

  1. Target Setting

    Attenuation target and frequency band stated first — for example the 1 to 100 MHz band where these tapes are characterised.

  2. Tape Selection

    AL/PET composite up to 70 dB with Mylar foil, or copper polyester at around 100 dB where the target is higher.

  3. Braid Specification

    Wire grade from CCA, CCS, CCAM or Al-Mg and coverage percentage set against cost, weight and solderability.

  4. Drain Wire

    Tinned copper gauge fixed, typically 0.4 or 0.5 mm², so grounding continuity is consistent.

  5. Slitting and Reeling

    Tape width from 2 mm and wire reels sized for your braider carriers.

  6. Verification

    Overlap and coverage checked on finished samples rather than on incoming material alone.

FAQ

Shielding Material Programme FAQ

How much attenuation can foil shielding deliver?

Aluminium composite tapes reach up to 70 dB when used with Mylar foil, and copper foil polyester tape reaches around 100 dB, both characterised in the 1 to 100 MHz range.

Which braid wire is lightest?

Al-Mg alloy wire, which has the best weight-to-strength ratio, though it is not solderable.

What drain wire is standard?

Tinned copper, typically 0.4 to 0.5 mm², depending on the construction.
