To avoid exceeding the maximum temperature is generally integrated suffered the highest temperature is 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 ℃, time of about 7 seconds . High speed ECL circuit, the power consumption is also large. When used in small systems, radiators should be installed on the device; for large, medium-sized systems Nanjing Qantas accessories, you should install the air-cooled or liquid-cooled equipment. Use LM258P FET FET precautions species and varieties more series, but their circuit test and measurement method is basically the same principle. During transportation and storage of insulated gate type field effect transistor, because of its very high input resistance, antistatic ability, there is no inner tube as fast as semiconductor protective element, generally its three pins storage under short circuit, in order to avoid static discharge breakdown the insulation layer, the circuit under test and its reliable connection, then the short route Nanjing fast removal of electronics, then measure. Process should be very careful thorough test operation Qantas, the slightest mistake, causing floating gate, is likely to cause damage.
