Added the energy conservation certification standard for domestic solar hot water systems based on the standard GB 26969-2011 "Energy Efficiency Limits and Energy Efficiency Ratings for Domestic Solar Hot Water Systems", which was issued on July 19, 2011 and will be implemented on August 1, 2012. .
The GB/T 19141-2003 for the technical conditions of domestic solar hot water systems was changed to GB/T 19141-2011, which was released on September 29, 2011 and implemented on August 1, 2012.
Factory inspections increase the requirements of the GB 26969-2011 standard.
HDI PCB or High density interconnect PCBs are a way of making more room on your printed circuit board to make them more efficient and allow for faster transmission. It's relatively easy for most enterprising companies that are using printed circuit boards to see how this can benefit them.
High density interconnect (HDI) PCBs represent one of the fastest-growing segments of the printed circuit board market. Because of its higher circuitry density, the HDI PCB design can incorporate finer lines and spaces, smaller vias and capture pads, and higher connection pad densities. A high-density PCB features blind and buried vias and often contains microvias that are .006 in diameter or even less.
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.
