### Flat component lead

These leads are soldered directly on the mounted pad present on the PCB. These leads are commonly used where high pin-density IC packaging on both side of PCB is required, such as in QFPs and QFJs (PLCC) packages. To avoid any damage, the leads are stored in special carriers and are cut and bent to Gull Wings with the help of lead forming equipment before use. Since this process incurs extra cost, these are the least popular type of leads.
