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)

Chipbond models: CBM7010, CBM7026 Detailed introduction: Problem: Due to the interference from the radio, the keypad of the dispenser will leak or leak. This case is quite special, because before the customer uses our company's touch button control chip, the product of a famous Korean chip company is applied. Due to the radio interference of the walkie-talkie, the water dispenser touches the keys and jumps the keys and leaks and malfunctions, causing customers to lose nearly 2,000 key control boards. After the control board was reimbursed, the technicians tried a number of domestic and foreign companies' chips. It did not help, and they could not effectively prevent the radio from erroneously triggering the touch keys or causing the keys to fail. In the case of incompetence, the customer's technical staff consulted our engineers for solutions to related problems. During the communication between the two parties, we learned that our chips have superior performance in terms of anti-interference, stability and sensitivity. And therefore decided to adopt. The result was surprising. Using a 5W (professional-grade) walkie-talkie (the power of ordinary walkie-talkies is only 0.5-1W), the frequency is 400MHZ-460MHZ, and the talk is performed at a distance of 1cm from the key spring. The touch button is triggered without error, and the sensitivity is still normal .
