First article inspection

Kingford conducts product quality inspection before the batch starts, in order to avoid large batches of defective products due to process and operation reasons.

The basic elements of SMT chip processing technology

Another important consideration when designing automotive system boards is grounding. Since the vehicle is not in contact with the ground, its electronic systems must be designed to take advantage of chassis grounding technology

Knowledge of electronic circuits essential for PCBA electronics engineers

Assembly drawings vary according to different assembly templates. Most of the time, because electronic products use the printed circuit board described below, the printed circuit board diagram is the main form of assembly diagram

Serial communication Protocol - Part 3: RS-232

The main disadvantage of using RS-232 is that its communication speed is relatively slow compared to other serial communication protocols. In many applications, it can only reliably reach speeds up to 128 kbps. Another disadvantage is that it can reliably

The basic operating procedures and processes of the dynamic SMT mounter

we provide the board for the machine, but also need to provide the corresponding installation components, the storage location of the parts is called the feeder, we will reasonably install the feeder on the bracket, and then provide drawings and installat

How to improve the assembly efficiency of SMT mounters?

Manual cleaning should be carried out at least once every 2 hours to reduce poor print quality and lead to poor shutdown in the case of too high. Therefore, attention should be paid to monitoring once every hour 5, the line body balance ratio must be abov

New energy vehicle PCB copying board will become a breakthrough in "haze control"

In addition, the high cost of construction also directly restricts the popularity of domestic new energy vehicles. Therefore, we can use reverse research and development technology to carry out PCB copying research, and we can seek new ways to reduce prod

How can the automatic optical inspection system be used in the production of printed circuit boards

Practice has proved that it is difficult to find each and every solder paste fouling only by sampling the printed circuit board samples. Only 100% inspection of all circuit boards can ensure greater inspection coverage, thus enabling statistical process c

SMT electronic manufacturing equipment automation analysis

Technology refers to a technology in which chip components are mounted and welded on the surface of the printed circuit board. Compared with the traditional through hole assembly technology, the technology has the advantages of high assembly density.
