Highly adaptable board level shielding can increase layout possibilities

20-12-2019 | Harwin | Subs & Systems

Aiding engineers dealing with EMI/RFI issues in their PCB designs, Harwin has introduced three new shielding cans. Supplied in a tape-and-reel format, these cans expand the company’s existing range of EMC products. The dimensions for the cans are 10mm x 10mm, 15mm x 10mm and 30mm x 10mm. All cans have a 3mm profile height and 0.15mm thickness material.


Each can is constructed from a single piece of unplated nickel silver alloy, with a simple five-sided shape. These cost-effective items are simple for engineers to fit onto a board, with the use of the company's SMT shield can clips. Secondary soldering operations are removed, as these clips are soldered at the same time as the other items populating the PCB. The risk of damaging sensitive circuitry during exposure to intense heat during hand soldering is avoided.


With the new additions, the range comprises 10mm square to 50mm x 25mm sizes, with heights from 2.5mm to 5mm and material thicknesses of 0.15mm to 0.3mm. Ready-made, these products are all offered in volume directly from stock.


“Tackling electromagnetic emissions is a vital aspect of modern electronic designs, particularly for those involved in wireless communication,” states Neil Moore, product manager for EMC and Industrial Products at Harwin. “The simple shielding cans and clips from Harwin have gained widespread popularity with electronics engineers. Now we are delivering a wider choice, aimed at helping with EMC requirements in the smallest handheld and wireless applications.”
