Description
Technical Field
[0001] The utility model belongs to the technical field of tin furnaces, and more specifically relates to a bottom exhaust type tin furnace. Background Art
[0002] With the development of social economy, professional work has become the most common way of employment for modern people, and occupational health has also become one of the hot topics of concern. Improving the working environment is an important way to ensure the occupational health of practitioners.
[0003] In the chip reliability test project, the solderability test is an indispensable test project. In addition to using automatic tinning equipment during the test, in many cases, a tin furnace is also used for manual tinning. In the test, the sample with flux needs to be placed in the tin furnace for the test, and the emission of toxic and harmful gases is inevitable. Long-term inhalation of this toxic and harmful gas may cause dizziness, coughing, and even pneumonia in severe cases. Figure 1 The existing tin furnace includes a tin container 1 for storing liquid tin, a heating component 2 for heating, a temperature sensor, a housing 3, and a control unit 4, etc. The operating steps of the tin immersion experiment are as follows: first, the chip is placed under a microscope for appearance inspection, and then the sample is immersed in flux, and then the sample with flux is placed in the tin container 1 of the tin furnace for 5-10 seconds, and the tinning situation is observed after taking it out. When the sample with flux enters the tin furnace, it will inevitably emit toxic and harmful gases. The existing tin furnace does not include an exhaust structure. The usual treatment method is to set a vacuum exhaust pipe 5 above the tin container of the tin furnace to achieve the emission of harmful gases. The vacuum exhaust pipe 5 used externally is placed above the tin furnace. If its placement position is too close to the tin furnace, it will affect the operation of the operator in the experiment, resulting in inaccurate experimental results; if its placement position is too far from the tin furnace, the harmful gas flow path is shown as the dotted arrow in the figure, and the harmful gas in the experiment cannot be completely sucked away, and there will be some overflow, and the operator will inhale too much harmful gas, causing damage to the body.
