QFN bad soldering is often happening in SMT assemble, consider from many aspects, such as pad design, PCB storage, chip control and management, solder paste management and use, furnace temperature ...

QFNs can be a bit intimidating, but they’re here to stay. With a little extra care, you may be able to shrink your board a little and save some of the fabrication costs. QFNs can be a bit intimidating ...

[Erich Styger] was bit by a nasty gotcha when soldering a QFN surface mount chip. The problem rears its ugly head when combining a chip possessing a padless conductor and a PCB without a solder mask.

Semiconductor manufacturers have developed innovative production techniques that enable the integration of multiple components and a dc-dc converter IC die into a single module. Producing such a dc-dc ...

Via in pad seems to be one of the hot topics these days. It's a bit of a tough one, too. The SMT guys pretty much always say, "don't ever do it." However, with certain parts, the component ...

Okay, we think it’s questionable when people say they have no problem soldering QFN packages, but BGA? Granted this chip has far fewer balls on it than many, but it’s still quite impressive that ...
