Soldering LFCSP ICs by Hand
Lead Frame Chip Scale Package (LFCSP) integrated circuits are devices with dimensions that are apparently determined by the required number of connections. Some of them are only a few square millimeters in size. For the connections to the outside world, there are small contact pads on the bottom along the four sides, each measuring 0.6 x 0.25 mm with a spacing of 0.4 mm. A small ground plane is located in the middle. Soldering these ICs to a PCB by hand can be very difficult.
