My first PCB is a simple LiPo battery monitor adaptable to the Adafruit feather line of products.
The thing I’m most worried about is soldering the IC to the board. It’s a 3 by 3 mm TFDN package with 14 0.4mm spaced pins, but most importantly an exposed pad. From a little searching on the web, I decided to add via in the IC landing that connects to a filled copper area on the back. Hopefully this will help with soldering the exposed pad by heating the copper area with an iron and a little solder. Do you guys think there’s a better way to do by hand?
Regarding fabrication, I’m thinking of going with BayAreaCircuits. They aren’t the cheapest but because I need the boards in a rush and I’m in Canada, I thought they might be a good option. If you have any other good recommendations for fast turn-around PCB fabs in the US or Canada I would love to know about it. I’ll be placing the order tonight.
Here are the rest of the components which are all through-hole so soldering shouldn’t be an issue.
The IC is a TFDN with 0.4mm pin pitch which is on the smaller side. I’m thinking of going with BayAreaCircuits for fabrication and I’ve selected the minimum track width spacing option of 5 mil.

Sorry I couldn’t post links to the components, since it’s my first post I’m not allowed to post more than one link. But these are the names of the components I am using.
Any and all input is greatly appreciated!
