Summary

Conclusions

Although QFN devices present a challenge to the SMT assembly process with proper stencil design, proper stencil technology selection (Laser, Electroform, Nano-Coat), and proper PCB solder mask layout these challenges can be overcome. The most popular QFN repair seems to be to print solder paste directly onto the QFN leads and ground plane.
