(dip of class ii or better). the product is manufactur ed with a patented process, which is fully automated, and ?in-line?. this ensures that there is no contamin ation or mechanical stress on the lead-frame so that the co planarity and solderability are maintained. the product is shipped in jedec trays to ensure preservation of the co-planarity and enable fully automated assembly in the final application (within 0.1mm). . pick & place assembly: the product is designed with a large flat area in the center of the top surface to serve as a pick up point for automated vacuum pick and place equipment. the ?open board? construction of the unit ensures that weight is kept to a minimum. however due to the relatively large size of the component, a large nozzle (> 8.0mm, depending on vacuum pressure) is recommended for picking and placing. the unit may also be automatically handled using ?odd- form? placement equipment, with mechanical grippers. for this type of equipment the end edges of the device, which have no leads and also feature the greatest dimensional accuracy, should be used as pick-up points. restriction curve above 215oc peak temp. at pins 1 and 10 (oc) 200 205 210 215 220 225 230 235 240 245 10 20 30 40 50 60 tp (s) time (s) 0 50 100 150 200 250 300 0 40 80 120 160 200 240 280 320 360 400 440 max. temp. on pins 1 and 10 during reflow soldering (deg c) tp peak temperature (see fig below) 190 ? 450 s
