How to judge the quality of HDI circuit boards? Shenzhen HDI circuit board manufacturers (Shenzhen Zhongke Circuit) have summarized some methods, which are shared with you below.
High-quality HDI circuit boards need to meet the following six requirements:
1. Whether the line width and line spacing of the HDI circuit board meet the requirements to avoid circuit heating, open circuit and short circuit. (All HDI circuit boards of Shenzhen Zhongke Circuit have been 100% tested)
2. High temperature, high humidity and special environmental tolerance should be considered.
3. The copper surface is not easy to be oxidized.
4. No additional electromagnetic radiation.
5. The shape should be free of deformation, and the hole position of the HDI circuit board and the deformation error between the circuit and the design should be within the allowable range.
6. The high-temperature copper skin is not easy to fall off (all HDI circuit board products of Shenzhen Zhongke Circuit will pass the IPQC inspection after each process is completed before the next process can be done)
Shenzhen Zhongke Circuit Technology Co., Ltd. is a high-precision PCB multi-layer circuit board manufacturer, focusing on high-precision double-sided/multi-layer circuit boards, high-end HDI boards, HDI circuit boards, PCB circuit boards, HDI circuit boards, Rigid-flex board, high-frequency board/high-frequency circuit board, PCB blind buried hole board, special circuit board, etc. The factory has imported and domestic boards all year round: the dielectric constant ranges from 2.2 to 10.6.
