PCB = printed circuit board and PCBA = printed circuit board assembly. For PCB, it means the copper circuits be printed on a board, and so the main composition are copper and board.
The copper is the circuits material and the circuits designed by the PCB designers. Depends on the current in the circuits, the PCB copper thickness could be done with 0.5oz-10oz. But the PCB designers need be noted that the copper track width/space need be enlarged with the thickness. For example, the minimum copper track width/space could be 3mil/3mil with 0.5oz, but would be 4mil/4mil with 1oz.
The PCB board could be rigid PCB, could be flex PCB and also could be Flex-Rigid PCB. And the materials could be FR4, PI, Aluminum, Copper-based, Rogers, Teflon, etc. They have different applications. For example, FR4 PCB is the most commonly used for rigid PCB and almost good for all electronics products; PI is the most commonly used for flex PCB; Aluminum and copper-based have good thermal diffusivity and always used for LED PCB ; Rogers PCB and Teflon PCB are always used for High Frequency PCB, etc.
We are the one-stop shop for all kinds of PCB manufacture service from PCB Prototype to big volume, which could save our customers a lot of time and money.

According to the introduction of the general manager, at the beginning of the establishment of BMTC, there will be sufficient research on the LED industry, and the positioning of its own competitive advantage is also very clear. Therefore, it has made great progress in research and development, products, production capacity and customers in the past six months. The fruitful achievements of Guangzhou Exhibition also prove that Zhaochi has achieved a breakthrough in the research and development of LED products.
Package development and product parts, the most widely used 3528 exhibit sample products, the photoelectric parameters averaged 8.2275lm (IF = 20mA), natural white light color temperature consistency is high, the light efficiency averages 128.57lm / W, the highest light efficiency is close to the industry peak The index of 140lm/w and 160lm/w, and the other 1, 3, 5W high-power package samples have received extensive attention in the industry during the exhibition. The backlight samples with their own packaging solutions are also the differentiated products that stand out from this exhibition. Further highlighting the differentiated competitive advantage of Zhaochi energy-saving lighting in the industry, it is reported that Zhaochi energy-saving lighting will officially start mass-cutting into the supply chain of Zhaochi's consumer electronics business in June, and successfully realize its own resource superposition target! Adhering to the company's “skilled and efficient†corporate culture, the company has the confidence to lead the industry in terms of capacity planning and layout, and strive to become the industry's most cost-effective LED solution provider in the future, spanning two areas of backlight and lighting applications.
In the LED lighting product segment, the product tree display of Zhaochi Energy-saving Lighting has attracted professional customers to stop in consultation. Through the mega product tree, we can see the system planning of Zhaochi's existing superior products and future products. At present, the basic products of Zhaochi have been listed. More than ten products of this exhibition are all original designs. The appearance is novel, and the overall photoelectric parameters are excellent. The average CRI is 80, and the average light efficiency exceeds 85lm/W! The most interesting thing on the spot is the comparative demonstration experience of LED fluorescent lamp products. The megaphone 18WT8 fluorescent lamp is in line with the international famous brand traditional 36WT8 fluorescent lamp. Whether it is luminous flux, glare value, brightness, uniformity and average illuminance, it can be obvious. Feel the superior performance of the mega LED fluorescent lamp. In addition, the integrated lighting series, the integrated lighting series, the engineering lighting series, the special lighting series, the BMTC intelligent control series, etc. are waiting to be launched, and the customers are getting a lot of inquiries at the exhibition site. Based on the objective demand and understanding of the market, the extensive market application development value of Zhaochi Energy-saving Lighting has attracted a large number of professional customers at home and abroad to come to the booth to inquire, so that the BMTC booth will undoubtedly become one of the most popular booths in the exhibition.
