Double sided PCBs
Double-sided circuit boards (PCBs) are the most basic type of printed circuit board. Both sides of their insulating substrate are covered with conductive copper layers to form conductive patterns, and electrical connections between the two sides are achieved through metal vias.
Double-sided PCBs are suitable for consumer electronics, industrial control, automotive electronics, and other fields. Due to their high wiring density and small size, they are often used in complex circuit designs. Compared to multilayer boards, they are lower in cost, have shorter production cycles, and are easier to repair, but they have poorer high-frequency performance and limited heat dissipation capabilities.
