[0002] Zener diodes are categorized by their breakdown voltage. Because of this characteristic, they are primarily used as voltage stabilizers or voltage reference components. A characteristic of a Zener diode is that the current across it remains essentially constant until it breaks down, even when reverse current is applied.

[0003] Zener diode chips are very small, and before they are cut and separated, they are generally processed using a wafer layout method, undergoing a series of operations such as glass paste coating, wiping and polishing, photoresist application, and dicing. The traditional method for applying glass paste to the chip surface is to place the chip layout on a rotating platform and apply the paste to the chip layout using a handheld scraper dipped in glass paste. During the glue application process, since the arm is usually resting on the table, this not only causes fatigue but also affects the uniformity of glue application. Secondly, when workers remove and place the chip layout, they usually place the scraper on the table, which affects the cleanliness of the table, especially the tendency to stick a lot of glass paste, resulting in waste of glass paste, and also affects the efficiency of workers in removing and placing the scraper.
