Do You Know the Reasons Why Hot Pot Slices Cannot Pop Up When Pressed?

If the pot flakes cannot pop up when pressed, it is also called the phenomenon of the pot flakes being keyed. This is fatal to the pot flakes; it directly causes the entire product to not work properly. So why does the pot flakes become keyed? Let's briefly explain. Analyze it:

1. The thickness of conventional pots is 0.06mm, and their lifespan is 500,000-1.5 million times (according to load requirements). When the lifespan reaches or exceeds 2 times the design life, it is easy to cause the KEY to not rebound and die;

2. The conventional design rebound value of the dome piece is ≧ 40gf. When it is lower than the special design value of 40gf, as the service life is extended and reaches the life limit, the KEY will not rebound and die;

3. The pot is made of stainless steel, and its designed thickness is generally in the [0.06~0.1mm] range. The conventional design load value is 100~300gf. When the pot bears more than twice the design load for a long time, it may easily cause failure;

4. When removing the release film of the dome patch before attaching it to the PCB board, or when producing the dome patch, if the dome patch is bent during the operation, the dome patch will be bent due to external force and the KEY will not rebound easily ( The pot piece is damaged or creased, or the concave shape of the pot piece itself is changed due to external force);

5. The dome patch is not designed with a breathable groove. When the dome travels, the air cannot be discharged, resulting in a dead key phenomenon when the load cannot be pressed;

6. When the design does not reserve a pre-pressure stroke, the silicone or plastic guide posts will act on the pot for a long time, making the pot heavy, reducing the service life of the pot and causing a dead key or non-pressing function.
