Number of keys: 10-22 Chip State Model: CBM7026 Detailed introduction: Problem: Microwave leakage of microwave oven products causes keys to malfunction. After testing, our model CBM7026 capacitive touch key control chip has successfully solved the problem of key failure caused by microwave leakage of a certain brand of microwave oven products. The microwave model of the customer model M502 uses the chips of two famous chip companies in the United States and South Korea, but during the test process, when the microwave radiation exceeds 5mW / C㎡, the microwave leaks repeatedly when the door is opened However, the failure of the touch button of the microwave oven or the crash of the microwave oven failed after several trials. After knowing the situation, our sales staff introduced our company's capacitive touch key control chip CBM7026 to our customers. After testing, even when the detector reached the full scale-10mw / ㎝², the keys still operated normally. After the problem was resolved, XB was identified by the customer as the designated provider of touch solutions, and was well received by the staff of the customer company. Note: (Microwave resistance test: domestic standard <5mW / ㎝². Chip state chip> 10mW / ㎝²)
