Circuit board proofing (PCB proofing) refers to the trial production of printed circuit boards before mass production. The main application is the process of small-scale trial production by the electronics engineer after designing the circuit and completing the drawing of the PCB to the circuit board factory. Proof for board (PCB proofing). Circuit board proofing [...]
According to the experience and insights I gained while repairing the circuit board, I would like to share with you friends. Our friends who have repaired electronic products know that in a complete electronic product, there is usually a piece of circuit board that is placed in different positions in the electrical appliance according to [...]

Yesterday, a physical experiment instrument was dismantled, and the EDM timer was used. The error mark on the instrument label was the electromagnetic dot timer. After dismantling and analyzing from the structure diagram, it can be seen that there is an electronic circuit inside, and the working power source is 220 volt AC, which is [...]
In the previous article, we conducted a comprehensive analysis of the sources, classifications, and hazards of pollutants generated in electronic processes. This article will introduce the evolution and development trends of cleaning technologies involved in electronic processes, and classify the currently used cleaning technologies. By comparing the advantages and disadvantages of different types of electronic [...]
Board damage: In the world, billions of boards are shipped from manufacturers every day. In our daily life, the waste circuit boards are also continuously produced, and the accumulation of used circuit boards has caused great harm to the ecological environment and even our body. The electronic components in the circuit board contain heavy metals [...]
Frenchtown-aries Electronics, n.j., offers new adapter kits that allow users of outdated Aromat HB2E relays to replace pins without the need for circuit board design or rework. The new Aries correct-a-chip 08-305984-11 adapter features the adapter bottom of the old Aromat occupying area and top of the new tx2sa-1v solid state relay. The new relay [...]
Circuit board {PCB circuit board}, also known as printed circuit board, is the supplier of electrical connection of electronic components. Its development has a history of more than 100 years; Its design is mainly layout design; The main advantage of using PCB is to greatly reduce wiring and assembly errors, improve the level of automation [...]
Printed circuit board (PCB) wiring plays a key role in high-speed circuits, but it is often one of the last steps in the circuit design process. High-speed PCB wiring has many aspects of problems, about this topic has been written a lot of literature. This paper mainly discusses the wiring problem of high-speed circuit from [...]
