(2) form a ground pattern as wide as possible to minimize ground impedance (to prevent undesired operation). (3) keep the wiring length of the ground pins as short as possible. (4) connect a bypass capacitor (e.g. 10 000 pf) to the v cc pin. recommended soldering conditions this product should be soldered in the following recommended conditions. other soldering methods and conditions than the recommended conditions are to be consulted with our sales representatives. p p p p pb1506gv, p p p p pb1507gv soldering method soldering conditions recommended condition symbol infrared ray reflow package peak temperature: 235 q c, hour: within 30 s.
