Powder temperature measurement: how to choose and use the most appropriate temperature measurement line

For reflow soldering process, both leather and fiber wires can be used For example, high precision is required The American temperature measuring wire is preferred, and the wire diameter can be within 1mm 2 For wave soldering temperature measurement, the finer the diameter of the temperature measurement line is, the better The transparent line imported from the United States is on the top When using, remember that the line head must be exposed, otherwise it will cause huge data error, resulting in meaningless test data When it is used again, the temperature measuring wire ends shall be cleaned one by one to prevent short circuit outside the welding 3 For the coating process, the temperature measuring line shall be simple, with durability as the core standard, and it is enough to use the measuring lines of mainland and Taiwan (the temperature resistance standard of the above three industrial temperature measuring lines is 300 ℃) 4 The heat treatment process generally adopts steel temperature measuring line with the diameter less than 5mm; under some conditions, the diameter of the test line is better to be coarse The temperature resistance of heat treatment process line is generally 600-1100 degrees Different testing processes have different details Please practice and summarize by yourself
