The baking oven is in the test process, and the equipment of guarantee chip stability plays crucial effect as getting rid of moisture among the integrated circuit.
Integrated circuit chips need to be screened for chip performance before being assembled into terminal electronic products. The performance screening process is a chip testing link. In the testing step, the wafer slices are packaged, and in order to ensure that the product performance is not affected by moisture, the wafer slices are subjected to a baking step before or after being tested by a performance testing machine, so that the moisture in the product is discharged. Typically, baking is carried out for more than 10 hours in an environment of over one hundred degrees depending on the process requirements.
At present, the chip baking box commonly used adopts the traditional mode and structure, namely, a multilayer clapboard is arranged in a whole large cavity and used for placing more baked products. According to production requirements, personnel place single batch or multiple batches of products in a baking oven, and set temperature, start heating and the like. When new products to be baked exist, the door of the baking box is opened to place the products to be baked in batches in the idle baking area. When the baking time of the product meets the requirement, an operator opens the door of the baking box with the heat insulation gloves to take out the baked product.

Second, toast the in-process and add the product of waiting to toast, need open cavity room door, will cause the inside temperature of toasting case and set for the temperature mismatch condition like this.
Thirdly, products to be baked are added in the baking process, and the products need to be placed into the high-temperature box by an operator, so that operation risks such as scalding exist.
Fourthly, during the process of taking and placing the products, the operation needs to be careful and slow due to high temperature, products placed inside and the like.
Fifth, there is a mix of risks during human handling, as the products to be baked and the baked products are not easily distinguishable.

and detecting whether the material to be baked exists in the baking cavity or not by using the detection sensor, if so, continuously starting the prompt alarm program, and if not, canceling the prompt alarm program to wait for feeding of the next batch.
9. The cooking method of claim 8, wherein said opening of the chamber door, placing the material to be cooked in the carrier drawer and pushing it into the cooking chamber, comprises the steps of:
clicking a chamber door opening button on the baking box body;
the working state of each baking cavity is displayed through a cavity label arranged on the cavity door;
scanning the bar code of the chamber label to perform system recording and information comparison so as to bind the material to be baked with the chamber label;
opening a chamber door of the baking chamber with an empty working state;
and placing the material to be roasted in a carrier drawer of a roasting cavity and pushing the material into the roasting cavity.
10. The toasting method according to claim 9 wherein said no-material warning routine comprises the steps of:
when the detection sensor detects that no material exists in the baking cavity, a cavity label arranged on a cavity door displays abnormity so as to perform no-material alarm prompt;
confirming on site manually, and eliminating alarm factors;
the chamber label returns to normal.
