High-precision printed circuits refer to the use of fine line width/spacing, micro-holes, narrow ring width (or no ring width) and buried and blind vias to achieve high density. High precision means “fine, small, narrow, thin”, which will inevitably lead to high precision requirements. Take line width as an example: 0.20mm line width, according to regulations,…

SPICE (Simulation Program for Integrated Circuits Emphasis) is a very powerful general-purpose analog circuit simulator developed by the Electronic Research Laboratory of the University of California, Berkeley in 1975. As the name SPICE indicates, it was originally used to verify the circuit design in integrated circuits and predict the performance of circuits, because this simulation…
As an electronic engineer, circuit design is a necessary hard work, but no matter how perfect the principle design is, if the circuit board design is unreasonable, the performance will be greatly reduced, and in serious cases, it may not work properly. Based on my experience, I have summarized the following points that should be…

Design basis of printed circuit boards The circuit design ideas of electronic designers must eventually be implemented in reality, that is, printed circuit boards. The substrate and selection of printed circuit boards, the physical properties of the various elements that make up the circuit, such as vias, slots, wire sizes, pads, surface coatings, etc., are…
1) In the design of low-power RF PCB, standard FR4 materials (good insulation properties, uniform material, dielectric constant ε=4, 10%) are mainly used. 4-layer to 6-layer boards are mainly used. In the case of very cost-sensitive, double-sided boards with a thickness of less than 1mm can be used. It is necessary to ensure that the…

(1) Talking about efficiency must start with management Among SNIT equipment, the placement machine is recognized as the most complex equipment. With the rapid development of assembly technology, its complexity will continue to increase. At the same time, since the cost of the placement machine accounts for a considerable proportion of the entire SMT processing,…
(1) Advantages and disadvantages of the turret structure · Up to 6 nozzles of different sizes are suitable for any placement head on the turret, and there is no need to change the nozzle during work. In other words, any nozzle can pick up components at any time, eliminating excessive and unnecessary operating steps. ·…
In the PCB electronic industry soldering process, more and more manufacturers are beginning to turn their attention to selective soldering. Selective soldering can complete all solder joints at the same time, minimizing production costs, while overcoming the problem of reflow soldering affecting temperature-sensitive components. Selective soldering can also be compatible with future lead-free soldering. These…
1.Introduction Welding is actually a chemical treatment process. Printed circuit boards (PCBs) are the support for circuit components and devices in electronic products, and they provide electrical connections between circuit components and devices. With the rapid development of electronic technology, the density of PCBs is getting higher and higher, and the layers are getting more…
