DFN Package Introduction
Advanced dual-sided flat no-lead packaging process
DFN Package Technology Introduction
DFN packaging is a new type of electronic packaging process that uses advanced dual-sided flat lead-free packaging. The conductive path between internal pins and pads is short, and the self-inductance coefficient and wiring resistance within the package are very low, providing excellent electrical performance. DFN packaging has high flexibility and provides excellent thermal performance through exposed lead frame pads with direct thermal channels for heat dissipation. Typically, the thermal pad is directly soldered to the circuit board, and thermal vias in the PCB help dissipate excess power to the copper ground plane, absorbing excess heat. QFN packaging (Quad Flat No-lead package) offers excellent electrical and thermal performance, small size, light weight, and other advantages.
Product Features
Miniaturized Design
Chip packaging has smaller dimensions with multiple pads at the bottom, significantly reducing PCB space occupation.
Excellent Thermal Performance
Chips can be directly connected to heat sinks to achieve excellent heat dissipation, improving chip operating stability and reliability.
Automation-Friendly Production
Features that facilitate automated production, improving manufacturing efficiency and product consistency.
