(dimensions in millimeters) frontsideview cellsize frontsideviewdetails backsideviewdetails moisturesensitivity,reflowsolderingandwashing information ixys has characterized the moisture reflow sensitiv ity of the solarmd using ipc/jedec standard j-std-0 20. moisture uptake from atmospheric humidity occurs by diffusion. during th e solder reflow process, in which the component is attached to the pcb, the whole body of the component is exposed to high process te mperatures. the combination of moisture uptake and high reflow soldering temperatures may lead to moisture induced delaminat ion and cracking of the component. to prevent this, this component must be handled in accordance with ipc/jedec standard j-std -020 per the labeled moisture sensitivity level (ms l), level 1. ixys does not recommend the use of chlorinated solvents. surfaceprotectionfilm please be advised that slmd module is normally cove red with protection film by factory to prevent it f rom scratch or dirt during the transportation, therefore it is highly recommended to remove the protection film at the end of your wo rk. especially when slmd should go through the high temperature process or e nvironment, the film should be removed in advance. if protection film is not wanted, please consult with us.
