What is a printed circuit board? A printed circuit board is a circuit formed by arranging conductive metal lines on an insulating substrate. In simple electronic projects, reconfigurable circuit boards such as breadboards or universal boards are often used, while printed circuit boards are fixed substrates that have these circuits pre-manufactured. The greatest advantage of … Read more
Although both packaging substrates (IC packaging boards) and printed circuit boards (PCBs) serve connection and support functions in electronic devices, there are essential differences between the two in terms of definition, functional positioning, technical parameters, material processes, and application scenarios. 1. Core Definitions and Functional Positioning Differences 1.Packaging Substrate lDefinition: A special substrate that directly … Read more
The essence of the industry is to burn money for technology; without money, you are out. Equipment is as expensive as a money printing machine, with an investment of over 1 billion for a high-end HDI production line, and even more for lines with more than 18 layers. Huadong Technology’s factory in Thailand invested 1.7 … Read more
