Made of common insulating materials and simple conductive traces, basic circuit boards are mainly single-sided or double-sided, featuring simple layout, mature processes and short production cycles. They deliver stable basic conductivity, good insulation and durability. Without complex lamination or high-precision processing, they are low-cost and highly versatile. They meet the circuit demands of low-voltage control, power modules, small household appliances, consumer electronics and simple instruments, supporting regular customization and mass production. As the most fundamental electronic component, basic circuit boards have a concise and practical structure, perfectly matching the circuit installation needs of most entry-level and civilian electronic products.
