4, Introduction: Shenzhen Saiheng Electronic Technology Co., Ltd. is mainly engaged in semiconductor components (integrated circuit IC and electronic components) products sales, research and development, production, inventory management and raw materials, component solutionsZhuo general wireless charging otp test , support 5W and Apple 5W, Samsung 10W wireless fast charging, the key is that the price is only 49 yuan, cost-effective can be said to crush the market similar 99 yuan products. In order to understand the workmanship of this product, the next thing to bring you is its unpacking.
The second part of the device material and structure, A: PNP type germanium material B: NPN type germanium material C: PNP type silicon material D: NPN type silicon material The third part of the function, U: photocell K: switching tube X: low-frequency low-power tube G: high-frequency low-power tube D: low-frequency high-power tube A: high-frequency high-power tube. In addition, the 3DJ type is a field effect tube, and the BT head indicates a special semiconductor component.
Hard disk should be repaired to a professional maintenance point We all know that the TV screen will absorb a lot of dust, and electrical components such as the hard disk will also absorb a lot of dust to the surface of the circuit board and the spindle motor periphery; In addition, the hard disk works in a humid environment, which will reduce the insulation resistance.
Whether it is the main circuit or the auxiliary circuit, the electrical components are arranged in order of action from top to bottom, from left to right, and can be arranged vertically or horizontally. (5) Mark the voltage value, polarity, frequency and phase number of each power supply circuit. (6) The contact of the relay and contactor is drawn according to the state of the suction coil without power, and the contact of the button and the stroke switch is drawn according to the state when it is not acted on by external forces.

MCU is short for Microcontroller Unit, which is an embedded computer system commonly used to control and controlPerform specific tasks. An MCU typically consists of a processor core, memory (including flash and RAM), input/output interfaces, timers, and communication interfaces.
MCU (MicroControllerUnit) Chinese name is called a multi-point control unit, also known as a single chip microcomputer (SingleChipMicrocomputer), refers to the emergence and development of large-scale integrated circuits, The computer's CPU, RAM, ROM, timer and a variety of I/O interfaces are integrated on a chip to form a chip-level computerThe same application occasions do different combination control.
MCU is the abbreviation of Microcontroller Unit, translated into Chinese is "microcontroller unit". A microcontroller is a single chip that integrates a processor core, memory, and various input/output (I/O) ports, typically used to control various functions and behaviors of electronic devices. MCUS are commonly used in embedded systems, such as home appliances, automotive electronic systems, industrial automation equipment, etc.
Download the official APP of the local city card (take Chengdu Tianfutong as an example), open the Tianfutong APP, and click the Tianfutong card. Find the top up in the page and click.
Open the official website of Chengdu Bus Card or the official website of Chengdu Public Transport Group. On the home page of the website or the bus card recharge page, select the option of "online recharge" or "Online recharge". Enter the bus card number and recharge amount, select the payment method (such as Alipay, wechat, UnionPay, etc.), and follow the prompts to complete the payment.
Bus card online can recharge, to Chengdu Tianfu TongFor example, click on the main page of the Tianfutong account to recharge.
Greatly convenient for cardholders. At present, there are two ways to recharge the platform: one is to purchase the Dudubao charging terminal, connect the Tianfu card to the computer through the USB interface, and use online banking or third-party payment to complete the online recharge; The other is mobile phone mobile payment, which requires NFC mobile phone support. Directly download the Dudubao APP software, scan and identify the Tianfutong chip with the mobile phone, and you can recharge the mobile payment through online banking or third-party payment.
Chengdu area now can recharge the bus card online, well, you can download that firstChengdu bus company APP, then you can top up.
Can only use Chengdu's own app, Alipay and wing pay are not allowed. Generally, small local companies are reluctant to open up their monopolized business to other businesses.
