What's Wrong With This Picture?

Vias through stencilopeningsWhat's wrong with this picture?

I forgot to warn you that there'd be a pop-quiz. It's only worth 10% of your final grade though, so not to worry.

We're fully into the rainy season here in Oregon now. It's dumping and the puddles are puddling up. Last weekend, we thought we were in for another big snow and ice mess, like December 2008, but it turned out to be just media hype. We warmed up and it's back to the usual 40 degrees and raining.

Unlike with a QFN thermal pad, we do want open holes in our streets. We want the liquidy stuff to go down underneath and not stay up top, 'cause that would make our feet wet and Johhny doesn't like wet feet.

If it's bipolar, it's a "collector." If it's a MOSFET, it's a "drain." What is it if it's a street?

The strange opening is for the pin one indicator on the chip. It really should be a silk screen object, not a solder paste object. And, yes, those two large vias are just asking for solder to eat.

Two things I found: strange opening in the top right corner, and two large vias at the center tab openings.

Yeah, the forecasters here are almost as bad at scaremongering as the PR for "2012"....

They bring out the "STORM TEAM!!!" if winds go above 10mph or there's any chance of decent rain, which is about every week in PDX.
