PCB soldering; circuit boards are divided into three major categories: single panel, double panel, and multilayer circuit board.


The first is a single panel. On the most basic PCB board, the parts are concentrated on one side and the wires are concentrated on the other side. Because the wire only appears on one side, it is called a single-sided circuit board. Single panels are usually simple to make and low in cost, but the disadvantage is that they cannot be applied to products that are too complicated. The double panel is an extension of the single panel. When the single layer wiring cannot meet the needs of the electronic product, the double panel is used. Both sides have copper-clad traces, and the vias can be used to turn on the lines between the two layers to form the desired network connection.


Electronic parts procurement; in 1906, the American inventor DeForestLee invented a vacuum triode (electron tube). The first generation of electronic products is centered on electronic tubes.


At the end of the 1940s, a semiconductor triode was born in the world. It was quickly applied by various countries because of its small size, light weight, power saving and long life. It replaced the tube in a wide range.


In the late 1950s, an integrated circuit appeared in the world, which integrated many electronic components such as transistors on a silicon chip, making electronic products more compact. The rapid development of integrated circuits from small-scale integrated circuits to large-scale integrated circuits and ultra-large-scale integrated circuits has led to the development of electronic products in the direction of high efficiency, low consumption, high precision, high stability, and intelligence.


Since the four stages of the development of electronic computers can fully explain the characteristics of the four stages of electronic technology development, the following four stages of the development of electronic technology will illustrate the characteristics of the four stages of electronic technology development.


At present, the company's main processing products are scanning equipment, fingerprint access control, handwritten PAD, USB equipment, GPS, mobile equipment, hotel controller. Petroleum-controlled electronic products are related products based on electrical energy.


Mainly include: smart phones, telephones, televisions, DVD players, video recorders, camcorders, radios, tape recorders, combination speakers, CD players, computers, game consoles, mobile communication products. Because the early products were mainly based on electronic tubes, the original electronic products.


Finished circuit board; circuit board soldering; the limitation of fine pitch devices is that the thin leads are easy to bend, brittle and fragile, and have high requirements for coplanarity and placement accuracy between the leads. BGA technology uses a new design thinking method, which uses a structure that hides round or columnar points under the package, with large lead pitch and short lead length. Thus, the BGA eliminates the problem of coplanarity and warpage caused by lead problems in fine pitch devices.


PCB boarding machine assembly test; as the carrier of various components and circuit signal transmission, PCB has become the most important and key part of electronic information products, its quality and reliability level determine the whole machine equipment Quality and reliability, due to the high density of PCB development and environmental requirements of lead-free and halogen-free, more and more PCBs have various failure problems such as poor wetting, bursting, delamination, CAF and so on. The acquisition of PCB failure mechanisms and causes will facilitate future quality control of the PCB, thus avoiding the recurrence of similar problems.


PCB soldering; circuit boards are divided into three major categories: single panel, double panel, and multilayer circuit board. The first is a single panel. On the most basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side. Because the wire only appears on one side, it is called a single-sided circuit board.

Electronic components are components of electronic components and small and small machines and instruments. They are often composed of several parts and can be used in similar products. They often refer to certain parts of the electrical, radio, instrumentation and other industries, such as capacitors and transistors. The general term for sub-devices such as hairsprings and springs. Common ones are diodes and the like.


The sale of components; the detection of electronic components is a basic function of home appliance repair. Many engineering maintenance and repair technologies in the security industry are actually derived from the maintenance and repair technology of home appliances, or borrowed or homogenized. How to accurately and effectively detect the relevant parameters of components and determine whether the components are normal is not a one-size-fits-all thing. Different methods must be used according to different components to judge whether the components are normal or not. Especially for beginners, it is necessary to master the testing methods and experience of common components. The following is an introduction to the testing experience and methods of common electronic components.


Component procurement; circuit board names are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin Circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc.


The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimization of electrical layout. The circuit board can be called printed circuit board or printed circuit board. The English name is (PrintedCircuitBoard) PCB, (FlexiblePrintedCircuitboard) FPC circuit board (FPC circuit board, also known as flexible circuit board flexible circuit board is made of polyimide or polyester film. A highly reliable and flexible flexible printed circuit board made of a substrate.
