How about the performance of circuit board potting adhesive? How can we guarantee it?

The circuit board is particularly sensitive. If the potting glue is not used in the manufacturing process, once it experiences turbulence, it is easy to vibrate and collide with the electronic components, resulting in electric shock reaction. This situation is a fatal blow to the electrical appliances, so in the production process, the circuit board [...]

How to extract gold from circuit board?

First, we need to prepare a scrap circuit board, hydrogen peroxide, toilet cleaner, gloves, goggles, disposable cups, beakers and coffee filter paper. Second, if the circuit board you are preparing is large, break it into a size that can be put into a beaker. The third step is to clean the dirt on the surface [...]

What are the necessary conditions for automatic soldering machine to solder PCB?

1. Weldment must have good weldability The so-called weldability means that the metal material to be welded can form a good alloy combination with the solder at a suitable temperature. Not all metals have good weldability, some metals such as chromium, molybdenum and tungsten have poor weldability; Some metals, such as copper and brass, have [...]

The circuit routing technique in PCB

Layout is one of the most basic skills of PCB design engineers. The quality of the routing will directly affect the performance of the whole system. Most of the high-speed design theories must be realized and verified by layout. Therefore, wiring is very important in the high-speed PCB design. In the following, the rationality of [...]

How to quickly identify which part on the circuit board is broken? Look at these seven first!

Capacitor fault The fault caused by capacitor damage is the highest in electronic equipment, especially the damage of electrolytic capacitor is the most common. The capacitor damage is manifested as: capacity reduction, complete loss of capacity, leakage and short circuit. Capacitors play different roles in the circuit, and the faults caused by them also have [...]

Discussion on the purpose of FPC circuit board impedance

FPC circuit board impedance refers to the parameters of resistance and reactance, which hinder the alternating current. Impedance is usually represented by Z, which is a complex number. The real part is called resistance, and the imaginary part is called reactance. The blocking effect of capacitance on alternating current in circuit is called capacitive reactance. [...]

What should we pay attention to when choosing PCB manufacturers

With the rapid development of integrated circuit industry, the demand for PCB circuit board only increases, but the market demand is large. PCB is the so-called printed circuit board, which is the support of electronic components and the indispensable carrier of electronic printing. At the same time, there are many PCB circuit board manufacturers, so [...]
