1. PLUG IN TO THE WIRELESS WORLD WISMO2D Shielding Parts Technology: metal sheet stamping and folding Frame : internal walls to isolate different RF areas with a folding edge to enhance rigidity and flatness (0.13mm) Cover : possibility to repair inside components by opening Cover assembly on a frame: locking by bumping on frame and opening in cover SMD functionality: high wetting without any worries on solder rising up (design update) Metal thickness Frame: 0.3 mm Cover: 0.2mm

2. PLUG IN TO THE WIRELESS WORLD WISMO2D Mechanical Specification 1 frame 1 cover

3. PLUG IN TO THE WIRELESS WORLD WISMO shielding frame design the frame design gives some constraints for components placement Example of typical frame on a PCB board Dimensions in millimeters 0.75mm between frame and board edge Lip width of the frame: 1.5mm without any components under 6x6mm surface for Pick & Place area Height of frame: 2 mm Height under lip 1.7mm

4. PLUG IN TO THE WIRELESS WORLD Shielding Definition Frame castellation with a thickness of 0.13mm. (0.13mm because it’s inch ‘s multiple); minimum value is 0.1mm 1,5mm 0,5mm 2 mm depending on Componnent height Aim of slot: Have a better planarity and like this less problem in production Better cooling of component in use Better Thermic evacuation while going to owen

5. PLUG IN TO THE WIRELESS WORLD Shielding Definition  1,5 In case of cover directly soldered on SMT( no frame), we need to add at least two holes on the cover. This hole has to measure less than 2,5 mm( in order to guaranty good RF performance: wave length issue). We used a diameter of 1,5mm as reference. Aim of theses holes Better cooling of component in use Better Thermal evacuation while going to owen

7. PLUG IN TO THE WIRELESS WORLD WISMO SMD shielding foot print Raw Material Issue: On the sample provided by Soutec, the material is tin plate steel. Our shieldings are in Nickel Silver definition We had a bad experience on tin plate steel in the past( our first project): Rust and Suntan Issue Nickel Silver is better: - for soldering - for moisture issue
