1. Can I directly lay the floor on the original brick? Buying a house, buying a house, decorating a forum, and a real estate forum are theoretically feasible, but it is important to note that the in-situ brick floor must be thoroughly cleaned and disinfected before paving the floor, otherwise the bottom of the floor will become bacteria and microorganisms. a breeding ground for future living
PCB Classify--can be considered as single-sided (one copper layer) board, double-sided (two copper layers on both sides of one substrate layer)board, or multi-layer(three copper layers or more) board. Multi-layer PCBs allow for much higher component density because circuit traces on the inner layers would otherwise take up surface space between components. The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of Surface Mount Technology.
