| Product Overview |
| |
| Based on a copper-made lead frame, VF Quad Flat No-lead (VFQFN) uses half-encapsulation technology to expose the rear side of the die pad and the tiny fingers, which are used to connect the chip and bonding wire to the PCB. The minimal interconnection makes the QFN packages competent to applications over 12GHz working frequency. Providing both thermal and electrical enhancement, QFN is a cost-effective solution to leadless packaging due to its economical materials and simpler packaging process. |
