notes on correct use (1) observe precautions for handling because of electro-static sensitive devices. (2) form a ground pattern as widely as possible to mi nimize ground impedance (to pr event undesired oscillation). all the ground pins must be connected together with wide ground pattern to decrease impedance difference. (3) the bypass capacitor should be attached to v cc line. recommended soldering conditions this product should be soldered and mounted under the following recommended conditions. for soldering methods and conditions other t han those recommended below, contact your nearby sales office. soldering method soldering conditions condition symbol infrared reflow peak temperature (package surface temperature) : 260 c or below time at peak temperature : 10 seconds or less time at temperature of 220 c or higher : 60 seconds or less preheating time at 120 to 180 c : 120 30 seconds maximum number of reflow processes : 3 times maximum chlorine content of rosin fl ux (% mass) : 0.2%(wt.) or below ir260 vps peak temperature (package surface temperature) : 215 c or below time at temperature of 200 c or higher : 25 to 40 seconds preheating time at 120 to 150 c : 30 to 60 seconds maximum number of reflow processes : 3 times maximum chlorine content of rosin fl ux (% mass) : 0.2%(wt.) or below vp215 wave soldering peak temperature (molten solder temperature) : 260 c or below time at peak temperature : 10 seconds or less preheating temperature (package surface temperature) : 120 c or below maximum number of flow processes : 1 time maximum chlorine content of rosin fl ux (% mass) : 0.2%(wt.) or below ws260 partial heating peak temperature (pin temperature) : 350 c or below soldering time (per side of device) : 3 seconds or less maximum chlorine content of rosin fl ux (% mass) : 0.2%(wt.) or below hs350 caution do not use different soldering met hods together (except for partial heating). data sheet pu10171ej03v0ds 16 pc3221gv
