Environmental, EMI/EMC Test Facilities and Laser Welding

Laser welding is performed in an inert gas atmosphere using argon and can provide spot, stitch and continuous hermetic (vacuum-tight) weld in a pulsed operation mode in a glove box. Any weld-compatible metals can be laser-welded and we commonly laser weld parts made from aluminium, for example, Al Alloy 6061 T6 for the package and Al Alloy 4047 for the lid. With their well-defined beams, lasers are excellent tools for welding thin materials with localised heating, without affecting the heat-sensitive components.
