* Question
| What are the design and wiring principles for a two-layer printed board? |
* Answer
| • The loop or guard line should be as close as possible to the high-risk signal line so that the RF energy is completely back to the source.The power and ground loops must be parallel to each other to provide decoupling capacitance for each component of the switching energy injection distribution system.The distance between the ground plane at the bottom of the board and the top signal line is very large. The two-layer board should be considered as two single-layer boards. Various techniques are used to ensure that the RF return path is physically close to all high-risk signal lines. |
