Board Level Products
MAJR Custom Board Level ShieldingMAJR specializes in the design and production of custom shielding solutions, shielding cans manufactured specifically to meet the requirements of exact EMI/RFI applications. Using precision Photo Etching techniques, MAJR can supply custom tailored solutions in a matter of days, so there can be little justification for maintaining stocks of cans with compromised, standard, design and dimensions. Ideally, cans should be designed to suit the application and not vice versa. This 'custom' approach is essential if functionality and the use of 'real estate' are to be optimized. MAJR has successfully assisted dozen's of companies in the co-design of shielding for board level explicit problems.
