ＳＭＤの両面実装プリント板。 In order to mount the SOP type SMD 2 on both the front and back sides of the printed board 1, the footprints 3 of the SOP type SMD 2 are provided at positions where they overlap on the front and back sides, and the through holes 4 or via holes connected to the printed wiring are located in the footprints 3. The SOP type SMD 2 is mounted at corresponding predetermined positions on both sides near the row, and in such a direction that the terminal row 6 including the power supply terminal 5 and the other terminal row 61 on the other surface overlap on the front and back sides. let me,
Set the direction of the power supply line to the corresponding SOP type SMD2.
A double-sided mounting printed board for SOP type SMD, which is characterized by facing the inside of the board.
