Magnetic shield and screen design can be a challenging area. Magnetic shields are made from soft magnetic materials i.e. those with very high permeability. Shield thickness is important, as any saturation in the shield material will make drastically reduce its shielding properties.
Best Solution uses leading finite element software for magnetic field analysis. For shielding problems, these techniques are very effective. The non-linear treatment of the materials with these tools enables us to assess shield thicknesses in different regions and to identify areas where shielding needs to be thicker, as well as those where no material is necessary at all.
Sometimes in sensitive equipment, interference can be caused by capacitively coupled voltages. The problem in these cases is one of effective electric field shielding. Again, Best Solution has access to software tools to assist in difficult electric field screening problems.
Our many years of experience in field problems enables us to work alongside our customers to find cost and performance optimised solutions to their shielding requirements.
