The QFN (Quad Flat No-lead) package is probably the most popular semiconductor package today because of four reasons: low cost, small form factor and good electrical and thermal performance. In this article we will provide an overview to QFN packaging, discuss QFN package technical details and ...

types is the potential for rework. The exposed leads of a QFP package are much easier to deal with than the hidden contacts of a QFN part. With some care, it is entirely possible to solder or desolder a QFP package by hand, where QFN packages absolutely require the use of a reflow ...
It was special because the original NES custom DIP chips had been sanded down to something like a surface-mount QFN package. Back when our colleague [Arya] wrote up the project there wasn’t much information, but since then the full details have been put up in a GitHub repository. Perhaps...
The specifically introduced geometric features in a side-wettable package (half-cut/half-etch/dimple) allow for a visible solder fillet to form on the side of all peripheral pins (Figure 9). The fillet can be visually inspected if the pins are soldered successfully to ...
The ability to mold many packages in one block on the QFN side, and then singulate to then chosen package body size has also made the QFN more versatile. Additionally, using the same mold for different package body sizes, without requiring any trim and form tooling, is an enormous cost-...

3.1 Land Pad Styles There are two basic designs for PCB land pads for the QFN and SON package—the copper defined or non- solder mask defined style (NSMD) and the solder mask defined style (SMD). The industry has debated the merits of both styles of land pads and although TI ...
