sd2943 mounting recommendations STEVAL-TDR005V1 8/11 doc id 14845 rev 2 6 sd2943 mounting recommendations 6.1 mounting recommendations ensure holes in heatsin ks are free from burrs; minimum depth of tapped holes in heatsinks is 6 mm; use 4-40 unc-2a cheese-head screws with a flat washer to spread the joint pressure; the minimum flatness of the mounting area is 0.02 mm; mounting area roughness should be less than 0.5 m (micro); avoid, as much as possible, use of flux or flux solutions because flux can penetrate even when hermetically sealed ceramic-capped transistors. tin and wash the printed- circuit board before mounting the power transistors, then solder the transistor leads without using flux; transistor leads may be tinned by dipping them full-length into a solder bath at a temperature of about 230 c. no flux should be used during tinning; recommended heatsink co mpounds: wpsii (silicon free) from austerlitz electronics, 340 from down corning etc. 6.2 mounting sequence apply a thin layer of evenly distributed heatsink compound to the flange; position the device with flat washers in place; tighten the screws until finger tight (0.05 nm); further tighten the screws until the specified torque is reached; for m174, m177 and m244 type of packages, torque should be minimum 0.6 nm and 0.75 nm max.
