Abstract

The invention discloses a temperature testing device and a temperature testing jig for wire end welding dotting. The temperature testing device for wire end welding dotting comprises a circuit board,an electrolytic capacitor bank, a K-type temperature sensing wire and a clamping part, the electrolytic capacitor bank is welded on the circuit board, the circuit board is provided with a metal welding point positive electrode and a metal welding point negative electrode, the positive electrode of the electrolytic capacitor bank is connected with the metal welding point positive electrode, the negative electrode of the electrolytic capacitor bank is connected with the metal welding point negative electrode, and the metal welding point negative electrode is connected with the clamping part through a connecting wire; the K-type temperature wire is provided with a detection end and an output end, the detection end of the K-type temperature wire is connected with the metal welding point positive electrode under the clamping of the clamping part, the clamping of the clamping part is removed when the K-type temperature wire is connected with the metal welding point positive electrode, and the output end of the K-type temperature wire is connected with a display instrument. According to the technical scheme, the reliability of the temperature test of wire end welding dotting in the circuit board is improved.

Description

technical field [0001] The invention relates to the technical field of temperature testing of circuit boards, in particular to a temperature testing device and a testing jig for soldering dots at wire ends. Background technique [0002] With the development of the economy, electronic products have become an important part of life. There are circuit boards in electronic products, and various components are integrated on the circuit board. Generally, the integration of components on the circuit board needs to be soldered by soldering. The temperature of the solder on the soldering point of the circuit board is very high, and it needs to be measured by temperature measurement. Among them, the K-type temperature-sensitive wire can be used to weld on the soldering point for temperature testing. However, K-type temperature-sensing wires are generally directly connected by twisting wires or soldered with a soldering iron. These methods will cause the two wires of the K-type temper...

Problems solved by technology

However, K-type temperature-sensing wires are generally directly connected by twisting wires or soldered with a soldering iron. These methods will cause the two wires of the K-type temperature-sensing wire to not be tinned, and the solder joints will not be firm.
