The important features of an excellent design of PCB

Laser cutting or drilling used in the PCB industry only requires several or a dozen of watts of laser instead of tens of thousands of watts of laser power. The application of flexible circuit board is becoming increasingly important in consumer products, automotive industry or robot manufacturing technology. As UV laser processing system has the advantages of flexible processing, high-precision processing effect and flexible & controllable processing procedure, it has become the first choice for soft circuit board and thin  PCB Manufacturer  laser drilling & cutting. To today, the long working life of the laser source equipped in the laser system is basically close to maintenance free. In the production process, the rate of laser is set as the first degree, which is very safe and does not need other protective devices. The LPKF laser system is equipped with dust exhaust apparatus, so it won’t discharge any harmful substances. Coupled with the visualized and easily operated

How to handle PCB components layout in designing LED switching power supply?

As a new member of switching power supply family, currently, LED switching power supply has been applied widely in many fields. In the R&D of new products, layout of PCB components is the most important part in designing LED switching power and a key test for engineers in designing the schemes as well. Then, what should we do achieve the best effects in the layout of PCB components? To achieve the best OCB components layout for the LED switching power supply, the first point which deserves full attention is the size of PCB before designing the layout of PCB components. When the size of PCB is too large, the printing wires will have to bee very long, leading to an increase in the impedance and a reduction in noise immunity, as well as a rising cost. In addition, once the printing wires are too long, neighbouring wires will be easily disturbed. Generally, the best shape for a PCB universal for the LED switching power is rectangle, with a proportion of 3:2 or 4:3 in length and width

The technological transformation and market trend in the PCB industry

As an important electronic connector, PCB is almost widely applied in all the electronics, which is considered as “the mother of the electronics”. Therefore, technological transformation and market research of the PCB industry has become the focus of many insiders. There are two obvious trends in the present electronic products: one is being light and short while the other is being high-speed and high-frequency, which drives the downstream PCB to develop into a high-density, high-concentration, encapsulating, sophisticated and multi-layer ones and contributes to a rising demand for high-layer plates and HDI. Being short in length of wiring and with low circuit impedance, high-layer plates, with the advantages of work with high frequency, stable performance, however, have more complicated functions, which is an unavoidable trend for the electronics technology to develop into a high –frequency, high-speed, multi-function, high-capacity ones. Besides, the further application of lar
