Mistake building first board

Recommended Posts

I soldered U1 RS485 8 pin and U2 Micro processor to the board.  I then realized there were sockets.  Will this still work?

My de soldering skills are worse than solder skills.

I would say try it as desoldering when  inexperienced will likely burn the chip anyway.

 

Just be sure Pin 1 is where Pin 1 should be.

If you ever have to replace of those chips, it's a lot easier to desolder each pin separately. Simply cut the chip off the board, then desolder the pins one by one.

Its not a big deal if you didn't burn the chip.  Also if you do not have a solder sucker, your trying too hard.   I wouldn't worry about it if it works without issues.  If you don't have the right tools though sometimes the job just isn't going to be fun.

It's not a problem if you don't fix it.  It might be if you do.
 

There are billions of circuit boards used around the world that don’t have sockets.

Not a good idea but unless you cooked the ic's during soldering it should be ok.

I am also not very good at soldering. The only purpose of the sockets is to prevent over  heating

of the ic's.

That's one important reason. Another reason is to allow a complex chip (like the CPU) or one that may be more vulnerable to damage (like the comm chip) to be easily replaced in the field.
