What is shielding in PCB?

By 19th July 2019 July 29th, 2019 No Comments

Printed Circuit Boards can be protected from harmful radiations using various different methods. These can include shielding cans and screening covers. The cans can be tailor-made towards your specific needs. EMI is an acronym for ‘electromagnetic inference’, and we can provide the excellence that you require if you are in need of EMI shields for your Printed Circuit Boards. Shielding combats the effects of EMI. EMI can occur due to cabling, which can pick up EMI from other sources as well as sending noise to other forms of equipment. Shielding is used to limit this interference.

Types of PCB shielding

The most effective and desirable EMI shields can be used when extreme manufacturing tolerances are needed. EMI shields can come in the form of covers, cages and lids. They can be given intricate designs and are often made from a wide range of metals and alloys. Features of EMI lids can include holes, clip detents and fitted dimples, offering swift and easy removal, and holes can be built into cans so covers can be clipped into place.

Shielding options

Small clips and pins can be built into shielding systems to provide tough protection against interference. These clips can be added to boards in a flexible manner and often require very little space. Lids can be secured via soldering when systems for heavy-duty applications are needed. These solutions are designed to deliver tough protection from harmful emissions.
