Regarding the straightener PCB cloning and prototype production, it is another major success case of our company. Dongdao Technology is a mature technology-based PCB cloning company in Shenzhen, specializing in PCB cloning, PCB replication, prototype production, chip decryption, and other services. Here is the introduction of the straightener:

The straightener, I believe many girls are familiar with it. It is a tool that can straighten or curl hair by heating. Generally, the straightener has 6 temperature settings: 110, 130, 150, 170, 190, 210 degrees Celsius. The voltage range is 110~220V. There are three buttons: power on, increase temperature, decrease temperature. After heating, it automatically shuts down after 60 minutes. NTC open circuit displays 110 and 130 indicators, the LED lights up, and the heating stops. NTC resistance unchanged heat display 130 and 150 indicators, the LED lights up, and the heating stops. NTC short circuit displays 150 and 170 indicators, the LED lights up, and the heating stops. The temperature error range is plus or minus 5 degrees. The heating time to the highest temperature is 2.5 minutes at 220V and 4.5 minutes at 110V. It should be reheated as soon as possible after the temperature drops during use.

In fact, the straightener is a simple controller, which has a main chip for control. Then, according to the buttons and gear settings, the temperature of the heating wire is selected. In order to consider cost, the main chip is generally a domestically produced chip. Below is the functional introduction of a straightener.

Functions:

1. LCD display (temperature value, heating status, negative ion working status)
2. LCD backlight (BLUE)
3. Negative ion function
4. Fahrenheit to Celsius conversion function
5. Button-type adjustable switch (increase temperature/decrease temperature, F/C, OFF/ON, backlight)
6. Digital temperature acquisition (NTC temperature sensing, MCU temperature control)
7. PTC heating element
8. Dual insurance function, machine power insurance and over-temperature insurance

Operating Instructions:

1. Plug in the power, the machine self-checks, and enters standby mode.
2. Long press the ON/OFF button for 3 seconds to turn on the power, default temperature is 80 degrees.
3. Tap the increase/decrease temperature button to set the temperature range from 80 to 200 degrees in 10-degree increments or decrements. The set value is displayed during setting, and it returns to the temperature measurement state after completing the setting for 3 seconds.
4. During heating, the temperature indicator bar displays as a running horse lamp from small to large in a loop. It stops when it reaches the preset value, and the heating stops at the same time.
5. Long press the increase temperature button for 3 seconds to complete the unit conversion of Fahrenheit/Celsius.
6. Long press the decrease temperature button for 3 seconds to switch the ION negative ion function, and the negative ion status bar displays as a running horse lamp.
7. Long press the ON/OFF button to turn off the power.
