Toyochem  has created a series of flexible conductive and insulating sheet films for the protection of electrical and electronic equipment, including EMC protection.

Toyochem Liotelan emi shield sheet
Branded Liotelant “the sheet films exhibit high water-resistance and are highly flexible, with an elongation of 500%”, according to the company. The “films can be hot-press moulded on to the electromagnetic interference source on the PCB, thus forming a lightweight multi-layer shield, more compact than a metal shielding can”.

Proprietary filler dispersion technology has been used to make the conductive films.

The idea is that an insulating film is first hot-pressed over the noisy component or PCB area, then a conductive shielding film pressed over that.

 

Applications are foreseen in wearables and communication devices.

Their global debut will be at Toyochem’s booth (1,016) at the International Microwave Symposium in San Diego next week.

Electronics Weekly has requested further techincal information ahead of the launch, so watch this space.
