Introduction
A K type thermocouple is also known as iron - Kang Tong is also a thermocouple, cheap cheap metal thermocouple. Its cathode (JP) on behalf of the chemical composition of pure iron anode (JN) for copper nickel alloy, often vaguely called Kang Tong, the name of its chemical composition: 55% copper and 45% the nickel and a small but important manganese, cobalt, iron and other elements, although it is called Kang Tong, but unlike Kang Tong and Kang Tong copper - nickel - chromium - Kang Tong, EN and TN can not be used to replace.
The areas covered iron Kang Tong thermocouple measuring temperature of -200~1200 DEG C temperature range, but usually used for the 0 ~750 °.Thermocouple good degree of linearity, thermoelectric large, high sensitivity, stability and uniformity is good, the advantages of cheap, widely used by users. The type J thermocouple can be used in vacuum, oxidation, reduction and inert atmosphere, but positive iron oxidation at high temperatures is fast, so use temperature is limited, can not no direct protection at high temperatures for curing atmosphere.

Application
Thermocouples are widely used in science and industry; applications include temperature measurement for kilns, gas turbine exhaust,
diesel engines, and other industrial processes. Thermocouples are also used in homes, offices and businesses as the temperature sensors
in thermostats, and also as flame sensors in safety devices for gas-powered major appliances.
SMT production line equipment
1. Universal SMT machine: Using the program edited by the device to mount components onto designated parts positions, it can mount SOP 28 pin or more (including components that can be mounted by high-speed machines) roll, disc, or tubular packaging components. Its characteristics are high precision and diversity, but its installation speed is inferior to high-speed machines.
2. Reflow soldering: Use SMT solder paste or red glue to set an appropriate temperature curve to complete the soldering action between the solder paste and the part.
3. Unloader: The board is loaded into the magazine through a transfer track.
4. Optical inspection instrument: Automatic optical inspection is a device based on optical principles to detect common defects encountered in welding production. AOI is a new testing technology that has only emerged in recent years, but has developed rapidly. Currently, many manufacturers have launched AOI testing equipment. When performing automatic detection, the machine automatically scans the PCB through a camera, collects images, compares the tested solder joints with qualified parameters in the database, processes the images, checks for defects on the PCB, and displays/marks the defects through a display or automatic marker for maintenance personnel to repair.
