Technical Field

[0001] The utility model relates to the technical field of diode production, in particular to a drying device for diode production. Background Art

[0002] A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). A diode has two electrodes, the positive electrode, also called the anode; and the negative electrode, also called the cathode. When a forward voltage is applied between the two electrodes of the diode, the diode is turned on, and when a reverse voltage is applied, the diode is turned off. The conduction and cutoff of the diode are equivalent to the on and off of the switch. The diode is one of the earliest semiconductor devices and is widely used. In particular, in various electronic circuits, diodes are reasonably connected with components such as resistors, capacitors, and inductors to form circuits with different functions, which can realize various functions such as rectification of alternating current, detection of modulated signals, limiting and clamping, and stabilization of power supply voltage.

[0003] The diode needs to be dried during the production process. In the prior art, the diode is fixed in the drying box, which makes it unevenly heated. In addition, the prior drying box is inconvenient to take and put the diode. In view of this, we propose a drying device for diode production. Utility Model Content
