I can't stand seeing or using non-SMD parts. Am I sick?

Surface tension pulled the soder pasted onto the leads?

Yep and adequate flux is your friend for this.  ;)

As an aside I've never been tempted to change my profile avatar such is my hate of that PB free muck they use these days.
CatalinaWOW:
No question, SMD is better in almost every situation.  But hate is the wrong response.  Because that will lead to picking the wrong answer sometimes.  Just recognize that for what you are doing SMD is a better answer and keep doing it.  If you do something different and it seems to be coming hard it is worth spending a few moments to see if you need to look elsewhere and this is where a hate response can leave you struggling unnecessarily.

One example: High power dissipation.  100W SMD resistors don't exist AFAIK, and an array of 200 half watt SMD spaced so they can dissipate power independently isn't a always a pretty answer.

To build a board with through-hole components:

* Pick up part
* Bend (or straighten) leads to fit through holes
* Insert part through holes
* Repeat for all parts
* Turn board over (hoping nothing falls out)
* Solder leads one at a time
* Clip excess leads (and hope you don't get one in your eye  :o)
* Optional: find all of the stray clipped leads that went flying
To build a board with SMD components:

* Tape stencil to board
* Apply solder paste and squeegee it across board
* Remove stencil
* Pick up parts with tweezers
* Place on board
* Repeat for all parts
* Put board in oven and reflow
I find the SMD procedure to be both less tedious and faster to do. The through-hole process assumes you don't have a wave soldering machine, which most hobbyists don't.

All that only really applies if you have a PCB made though, ex: higher volume.  Would not bother getting a PCB made for a one of project.   Doing SMD with bread boards or perfboards is not very fun.  Doable, but through hole is easier.

I mostly work with through hole myself but once I decide I want to get a PCB made for a project that I want many of then I'll probably convert a lot of stuff to SMD.

Getting a PCB made these days is so cheap I do it for every project, even one-offs (which the vast majority of my projects are).
