Aside from the obvious consideration of cost, are there any real advantages to using a socket instead of soldering surface mount components directly to a board?

 

I have not done any surface-mount / reflow soldering and wonder how many components I will trash in learning how to do it. Also, I would not be mass producing any boards, so the additional cost of sockets would not be necessarily prohibitive...

 

Thanks!

Sockets for SMD parts are not really very common. What some do is put the IC on a breakout board that then plugs into a standard socket. 

 

Personally, I have not used a socket (for anything) in maybe more than 5 years. Well, once for an M328, but that was it. On the other hand, Arduino Uno boards come with socketed M328. But, in both cases, those ICs come in DIP packages. 

 

For me, with most of my development boards coming from OshPark, the boards are so inexpensive compared to hardware that I can afford to discard a "bad" board for less than sockets would cost. Other factors  include area: sockets add a lot of area to otherwise SMD parts. Cost, if course (sometimes pretty big, actually). The other side of it is being able to change the part. 

 

I don't see it as a big difference, either way.

I have to make at least a few boards myself as my wife and son are intensely interested in the process -- hopefully they'll be relieved of that after a couple, I don't mind it so much, but storing and disposing of the caustic chemicals is just tedious -- but will look into having a couple / three manufactured for me.

 

Not sure I see the need to replace components in my limited use, adding a ISP header should be sufficient.

 

Thanks!
