Ordinary PCB line boards are mainly FR-4, which are compressed by epoxy resin and electronic-grade glass cloth. Generally, traditional HDI line boards should be used for bronze foil on the outermost side because of laser drilling. Can't open the glass cloth, so generally use glass fiber -free bronze foil, but the high -energy laser rig can already penetrate 1180 glass cloth now. This is no different from ordinary materials. For details, you can refer to the website of the China Science and Technology circuit. material!
What kind of PCB board is called HDI line board? What is the difference between them and ordinary double panels? There is also a high -frequency board that is usually suppressed with FR4 glass fiber board, and the whole epoxy resin glass cloth is suppressed. The color is relatively uniform and bright. The density is larger than the low -frequency board. Generally, high -frequency boards are used in circuits with a frequency of more than 1G. Its dielectric constant is the key. It must be small and stable. The medium loss is small. It is not easy to absorb water and moisture, heat resistance, and corrosion resistance.
HDI line board is a high -power density inverter (High Density Inverter), a telephone board with a relatively high line distribution density with micro -blind burial technology. It is a compact product designed for small -capacity users. It uses modularized parallel design, a module capacity of 1000VA (height 1u), naturally cooling, can be directly put into 19 "racks, maximum can be connected to 6 modules. This product uses full digital signal process control (DSP) technology and multiple The patented technology has a full range of adaptation to load capacity and strong short -term overload capacity.
Many general printing circuit boards are compressed with low-end materials, for example: paper base board, composite substrate, epoxy plate (also known as 3240 epoxy board, phenolic plate), FR-4 glass fiber board (patchwork board), Paper -based board and composite substrate.
