One of the capacitors: the role of the capacitor Capacitors, which are one of the passive components, function in the following ways: 1. It is applied to the power supply circuit to realize the functions of bypassing, decoupling, filtering and energy storage. The following classification details: 1) Bypass The bypass capacitor is an energy storage [...]
The first process: the operator loads the PCB into the turnover frame, and then loads the turnover frame into the upper plate case; the automatic upper plate machine feeds the PCB light plate to be printed with the solder paste into the printing machine through the track. The second process: the printing machine has installed [...]
Many small partners who have just touched the PCB industry often encounter the term aluminum substrate. So what is the difference between the aluminum substrate and the PCB board? Today, Xiaojie Ge will explain it to everyone: Generally, the aluminum substrates that we encounter are single-layer aluminum-based PCB boards, which are one kind of PCB [...]
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 [...]
In 1950, the first panel appeared. The single-panel material was made of paper phenolic substrate. The simple understanding of the double panel is that there are wiring on both sides. This makes it better. The multi-panel refers to more than 2 layers. Price, please see below The history of single-sided boards: The single-sided printed circuit [...]
The arrival of the 5G era has put forward higher requirements for the R&D, production and management capabilities of the majority of circuit board companies. Enterprises must provide more cost-effective products to the market at a faster speed, and it is very important to improve product management traceability. A ring. Marking characters, patterns, one-dimensional codes, [...]
Printed circuit board {PCB circuit board}, also known as printed circuit board, is the provider of electrical connections for electronic components. It has been developed for more than 100 years; its design is mainly layout design; the main advantage of using the circuit board is that it greatly reduces wiring and assembly errors, and improves [...]
Water-based cleaning process for circuit boards, how to choose the right cleaning equipment? - Heming Technology Key words: circuit board cleaning, PCB component cleaning, water-based cleaning technology, spray cleaning machine, ultrasonic cleaning machine The SMT/DIP electronic assembly cleaning requirements are based on the application, customer, rework and overall steps in the process, and are required [...]
Key words: circuit board cleaning, water-based cleaning, thermal oxidation, rosin, PCB component board In the electronic process technology, PCBA (circuit board or circuit board) often whitish after cleaning, and the white mark is scattered around the solder joints, which seriously affects the appearance acceptance and brings quality hazards. White Residue Risk Factor: When considering [...]
In the initial stage of debugging and the maintenance stage of the circuit board, the replacement and replacement of components are encountered. Disassembling the components is a technically hard work. If you pay attention to it, it will cause damage to the disassembled components. Even damaged the pad. The electronic components are sensitive to temperature. [...]
