The heat generated during the operation of the electronic equipment causes the internal temperature of the equipment to rise rapidly. If the heat is not released in time, the equipment will continue to warm up, and the device will fail due to overheating, and the reliability of the electronic equipment will decline. Therefore, it is [...]
"Do you find yourself wondering what exactly the circuit board assembly process is? Printed circuit boards are critical to almost all electronics today. They are widely considered to be green computer chips covered with copper wires and symbols screen printing. Printed circuit boards are usually made of fiberglass, copper traces, and other conductive materials, and [...]
The heat generated during the operation of electronic equipment causes the internal temperature of the equipment to rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, the device will fail due to overheating, and the reliability of the electronic equipment will decline. Therefore, it is important to [...]
What is a PCB circuit board Printed circuit board {PCB circuit board}, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantages of using circuit boards are greatly reducing errors in [...]
Most of the electrical energy consumed by electronic devices during work, such as RF power amplifiers, FPGA chips, and power products, is converted into heat dissipation in addition to useful power. The heat generated by electronic equipment causes the internal temperature to rise rapidly. If this heat is not dissipated in time, the equipment will [...]
Production method 1: 1. Cut the copper-clad board to the size required for the circuit diagram. 2. Put the wax paper on the steel plate, use the pen to engrav the circuit diagram on the wax paper 1: 1, and cut the circuit diagram engraved on the wax paper according to the size of the [...]
Vias are generally divided into three categories: blind vias, buried vias, and through vias. A blind hole refers to the top and bottom surfaces of a printed circuit board. It has a certain depth and is used for the connection between the surface layer circuit and the inner layer circuit. Buried hole refers to the [...]
The fundamental effects of circuit board chip inductors: filtering, oscillation, delay, notch, etc. Image saying of circuit board chip inductor: "through DC, blocking communication" Passing DC to circuit board chip inductor: The so-called passing DC means that in a DC circuit, the effect of the inductor is equivalent to a wire, and it has no [...]
There are four main quality characteristics of circuit board prepregs: Resin content (RC), fluidity (RF), gel time (also called geltime, GT)), volatile content (also called volatile content, VC) . In the military standard MIL-P-13949, there is also a control index for dicyandiamide crystallization. In recent years, FR-4 and its prepreg production factories have also begun [...]
When the circuit board has been designed and laid out, and the connectivity and other issues did not go wrong during the test, is the PCB circuit board done? Either there is no error or no problem with the circuit board. Many engineers with little experience and overconfidence end the PCB testing process. In mass [...]
