Package 135.9 12.19 3 C3 x P32.0=96.0 10.16 32.0 44.0 Notes : 1. The shape of the tray complies with JEDEC standards. 2. Product carrying capacity : 28 pcs./tray 3. Heat resistant temperature : 150 C max. (high heat resistance type) 4. The following markings must be indicated on the handle : 1) Company name : Shindengen 2) Package name : MSOP-14 3) Heat resistant temperature 6 x P44.0=264.0 315.0 322.6 4) Material Temperature Profile (C) 300 250 Within 5 seconds Modular lead : 220C max. 200 220C min. Within 40 seconds 150 100 50 0 0 40 80 120 160 200 240 280 300 (Seconds) 1) The atmospheric temperature of the modular lead should be 220 C for no more than 5 seconds. 2) Refer to the graph above for an example of a recommended profile. 3) Precautions Concerning Heating Method Since allowing the PWB to stand at a high temperature for an extended period of time may have a detrimental effect on reliability, it is necessary to perform soldering as quickly as possible to prevent the temperature of the PWB from rising excessively. In addition, since areas of local temperature rise may occur when using a halogen lamp or infrared heater, avoid irradiating the surface of the PWB directly. |
