Realization of Wettable Sidewall for Quad Flat NoLead Devices

Incorporating a wettable sidewall in quad flat no-lead devices is one the new requirement of automotive customers to improve its performance in board level application. An alternative solution is through leadframe design modification in conjunction with optimizing the singulation and the plating processes to create a quad flat no-lead (QFN) device exhibiting good wettability at the lead sidewall
