1, different meanings: SMT refers to a series of process processes based on PCB, PCB (Printed Circuit Board) is a printed circuit board.
2, in SMT (surface mount technology), CHIP and SOT are different types of electronic component packaging. CHIP (CHIP) : CHIP is a very common type of packaging for electronic components, usually used in Integrated Circuit chips (ics).
3, revised version: SMT is a surface assembly technology (Surface Mounted Technology (Surface Mounted Technology) is the most popular technology and process in the electronic assembly industry. SMT patch refers to a series of processes on the basis of PCB.
4, the choice of tools The basic tools for welding the patch components are small tweezers, soldering iron, tin absorbing belt, in addition to the need for a heat gun, anti-static bracelet, rosin, alcohol solution, magnifying glass with a lamp. The following is a brief introduction to the selection, use and function of smt chip component tools.
Use urgent,If the silk screen code of this triode is 1AM, then it may be MMBT390S8050, BC846 and other models of triode, depending on its manufacturer. The front screen print "58TI AIO" and the back screen print "46A P0Y7" are not its real model, but its manufacturer and batch code.
This chip is the Philips PCA9537 chip (4-bit I2C and SMBus low power I/O port)with interrupt and reset) - IIC and system management chip, 4-bit low-power IO port with interrupt and reset. Baidu Library has its detailed PDF information.
According to your description, this five-pin patch chip may be one of the circuit components of your car tachograph. "CDAW" is the model or manufacturer brand of this chip. If this chip is damaged, it may cause some of the functions of your dashcam to fail or not work properly.
KCV23DL. According to the inquiry Guangdong Weishi da electricityThe official website of the device Technology Co., Ltd. learned that as of April 8, 2023, the chip power chip of the Changdi electric oven produced by the company is the KCV23DL model.
This is the aerosemi M3406 more likely, this is 800mA 2~6V input, 5MHZ synchronous buck converter. The main function of the domestic analog ADI LTC3406. There are also a number of replacement parts in China, such as Tiangao Micro IA3406, Lingxin Micro LC3406. Note that the above mentioned are adjustable types.
This chip shouldThis is a domestic chip is relatively good, relatively speaking, from the effect is better, in this respect, it is worth choosing.
Different applications: SMT patch refers to a series of processing processes on the basis of PCB. PCB (Printed Circuit Board) is a printed circuit board. The integrated circuit that manufactures the circuit on the surface of the semiconductor chip is also called the thin-film integrated circuit.
Domestic chips are generally from abroad, like plug-ins are a lot of foreigners love good, such as pixel painting is an example.
According to the thickness of the film, the film integrated circuit is divided into thick film integrated circuit (film thickness of 1μm ~ 10μm) and film integrated circuit (film thickness of 1μm below) two kinds. Semiconductor IC, thick film circuit and a few hybrid IC are mainly encountered in the process of home appliance maintenance and general electronic production.
Patch and in-line are both common forms of chip packaging, they are functionally the same, but the chip size of the patch is smaller than that of the in-lineChip, it will also consume less power. However, the in-line chip also has its advantages, if the hole plate is welded, the chip package is not good for welding.
The difference is as follows: SMD is a component, SMT is a technology and process, one is an object, one is a non-object.
