What I like most about vintgage - NO SMD

I was tinkering with a junker and lifted a solder pad off. You do know that with SMD there is NOOOOOOO way in hell you can repair that!

Luckily like I said it was a junker I found. But I do have three pieces that are constructed mostly with SMD boards. And I WAS tempted to try some different capacitors out on them. Now - ain't no way I'm fooling with those. I like big clunky discrete components. Maybe even bigger - tubes!

I've dabbled in SMD with hot air rework. I built a software defined radio receiver where a majority of components were surface mount. It was quite the learning experience. Good lighting and a magnifier is a must.

The trouble with modern components, IMHO, is the use of all-tin solder, which is harder to get hot enough. I used 50/50 tin-lead paste. (I don't have to adhere to RoHS rules ;) )

I made one mistake of installing a 16 leg chip where it wasn't needed. With the hot air station, I was able to remove it without destroying the part or board. Old school solder irons with blunt tips don't work so well.

The most fun part is watching a part work itself into place by surface tension of the solder.

All is not lost, with the lifted pad. You can save the day using conductive, silver bearing, epoxy. However, that stuff is damned expensive.

I too have little love for SMD parts. There's no way in Hell I'm getting involved with solder paste and ovens. :> (( If SMD parts are the only way to solve a particular problem, I'll bite the bullet and buy the conductive epoxy.

I got good at SMD but a heat gun for removal is key IMO. My big issue is there aren't really good SMD parts.

  FWIW, I've seen some Schottky bridges that looked interesting.

    I do believe there will be better parts as time marches on. I'll continue to watch.

I agree,
SMD is evil, and should be confined to consumer products not likely to be repaired.

  They are, ain't no way you're fixing those boards!
  
  It breaks - it's landfill.
