What are the main defects that the Wellman X-ray inspection system can find on the QFP & QFN of PCB

March 30th, 2020|

Flat no-leads packages such as quad-flat no-leads (QFN) and dual-flat no-leads (DFN) physically and electrically connect integrated circuits to printed circuit boards. Flat no-leads, also known as micro leadframe (MLF) and SON (small-outline no [...]
