When installing an integrated circuit on a printed circuit board, pay attention to the direction of no mistake, otherwise, when the power IC is likely to be burned. General rule is: IC pin up to the gap or hit a point or vertical lines prevail, press counterclockwise arrangement. "." If a separate plug-in IC straight hand, places the front (printed side models trademark) toward yourself, pin down, pin numbering sequence is generally left to right. In addition to these conventional pin direction arrangement, there are also some pins arranged in the direction of more special attention should Nanjing Toshiba PBX, most of them belong to the single in-line package, which coincides with the pin arrangement direction opposite to the above said, suffix "R" Toshiba, such as M5115 and M5115RP, HA1339A and A1339AR, HA1366W and HA1366AR, etc., that are printed on one side toward you when pinout, pin down, the suffix "R" in the direction of a model or trademark from right to left, which are mainly two-channel audio power amplifier circuit, when connected BTL amplifier circuit, the convenience of printing plates are arranged symmetrically, and special design. HCF4013MO13TR To prevent the maximum temperature exceeds the maximum temperature is generally suffered IC 260 ℃, 10 seconds, or 350 ℃, 3 seconds. This means that all of the pins of each IC package substrate while immersed in the distance from the plane greater than 1 to the maximum time allowed by 1.5mm, wave soldering and dip soldering so temperature control in 240 ℃ ~ 260 ℃ Nanjing Toshiba Electronics, time for about 7 seconds. Nanjing high-speed ECL circuitry Toshiba dealer, power consumption is also large. When used in small systems, radiators should be installed on the device; for large, medium-sized systems, air-cooled or liquid-cooled equipment should be installed.
