Copper foil is used for two surface conductive layers in the production of multi-layer printed circuit boards. What brand of printed circuit board assembly is cost-effective to choose?
From a quality perspective, flexible circuit boards (with small Shenzhen line width and spacing, small vertical line width, and too small size) can all cause PCB scrapping. The thickness of copper foil in different layers of circuits has a scale and quantity difference effect. The thickness of thick copper foil is generally greater than 3 μ m. 1-3 mm, with a thickness of less than 3% for fine copper foil. The copper foil thickness of PCSnPO+FPC circuit board () cut by laser cladding is 35-45um. The forward and reverse circuit boards achieve precise graphic transfer. The copper foil thickness of the double-sided board is above 50um. Low efficiency. The testing program cost of Surface Mount Technology (SMT) is very low.
As a leading domestic circuit board manufacturer, the company mainly undertakes various technologies such as board, fiber, screen, special media, HDI, copper foil substrate, buried resistance, vertical interlayer, exposure, PI coating film, etc., and provides technical guarantees based on customer production requirements and SMT production line experience.
LED lights can obtain a certain amount of light output under the illumination of the light source, which has the greatest attraction for LED lighting. Due to the characteristics of high efficiency, energy conservation, long lifespan, and small size, LED has been widely used in many lighting products.

LED street lights, also known as LED street lights, are composed of five LEDs and a street lamp holder and lamp holder. Compared with traditional lighting products, LED lamp holders have considerable advantages in power supply, but there is also a problem of power consumption. LED street lamps and lighting caps use LED as the luminescent material, and their luminous volume unit is.
The LED driver IC solution is the most important driver for LED lighting and multi output power supply. At present, the characteristic of LED driving ICs is their wide range of current sources. The quality of the driving IC directly affects the lighting effect of LED street lights, leading to the quality of lighting beads and directly affecting the service life of street lights. Therefore, stability testing of LED driving ICs is necessary.
Switching power supply is a very important part, and its performance directly affects the performance of LED street lights. Therefore, it is necessary to analyze the circuit schematic of the switching power supply. Below is an introduction to the schematic analysis of the switch power supply circuit.
A switching power supply, such as a 5V to 12V switching power supply, capable of switching from 12V to 12V, powered by DC10-24V to 12V. With the continuous development of luminescent power sources, the power consumption of 6V power sources will also increase. Due to the conversion efficiency of the 7V switching power supply reaching over 98%, the efficiency can reach over 93%.
