Select the most suitable EMI shielding pad based on environmental and mechanical conditions【Selection】

Yimisi Electronic Materials Co., Ltd. is committed to providing engineers with a variety of solutions for controlling electromagnetic leakage. Yimisi's electromagnetic shielding pad is a high-elastic, high-conductive sealing solution that prevents leaks in doors and panels.

The most suitable EMI gasket for shielding requirements depends on the environmental and mechanical considerations of the equipment being shielded. This article aims to assist engineers in determining the best shielding or grounding products, taking into account mechanical constraints such as metal thickness, material type, coating, bolt spacing, and interface dimensions.

According to your application requirements, pressure-sensitive adhesive tape can be applied to the top or bottom surface of the shim. The following are the ways you can specify.

The optimal conditions for installing EMI gaskets involve a rigid machined flat surface, with bolts located outside the contact area of the gasket. However, this scenario is impractical or impossible in most shielding applications. Therefore, selecting EMI gaskets that meet the required shielding effectiveness while adapting to the interface limitations of the封装 is a primary consideration in designing effective EMI gaskets.

The most common grounding method between two mating surfaces involves installing a flat washer. This method is particularly effective in connectors that occasionally require the housing to be opened for maintenance. It is recommended to use a locking washer to prevent over-compression of the washer, securely close the cover after opening, and effectively reduce the sealing effect. All washer materials have an elastic limit and are prone to damage after being tightened.
