Proprietary & Confidential HClamp2481ZA Final Datasheet: Rev. 2.0 Revision Date: 7/12/2024 semtech.com HClamp2481ZA Typical Characteristics Assembly Guidelines The small size of this device means that care must be taken during the mounƟ ng process to ensure reliable solder joints. The fi gure at the right details Semtech’s recommended mounƟ ng paƩ ern. Recommended assembly guidelines are shown in Table 1. Note that these are only recommendaƟ ons and should serve only as a starƟ ng point for design since there are many factors that aff ect the assembly process. Exact manufacturing parameters will require some experimentaƟ on to get the desired solder applicaƟ on. Solder Stencil Stencil design is one of the key factors which will determine the volume of solder paste which is deposited onto the land pad. The area raƟ o of the stencil aperture will determine how well the stencil will print. The area raƟ o takes into account the aperture shape, aperture size, and stencil thickness. A minimum area raƟ o of 0.66 is preferred for the subject package. The area raƟ o of a rectangular aperture is given as: Area RaƟ o = (L * W )/ (2 * (L + W) * T) Where: L = Aperture Length W = Aperture Width T = Stencil Thickness Semtech recommends a stencil with square aperture and rounded corners for consistent solder release. The stencil should be laser cut with electro-polished fi nish. A stencil thickness of 0.075mm (0.003”) is recommended. A 0.100mm (0.004”) stencil may be used, however the stencil opening may need to be increased slightly to achieve the desired area raƟ o to ensure proper solder coverage on the pad.
