Title: Microcompiller socket
Post by: Blood-man on August 07, 2009, 06:56:03 PM

I have a problem with my socket. I ordered it from Digikey for AtMega8 for my $50 robot. It's the same socket as shown in the tutorial. So when I was making my robot, my AtMega8 didn't fit into socket. It was just like 1mm  wider than socket. So I used a brutal force, I was about to rip one lag off. So when I got it, it wasn't good. It was easy fall off. When I'm programming I got to hold the microcompiller. After that I got to hold it when the robot running, because if I don't only one wheel will rotate. Can I solder it in? Is there any other ways how can I make it to stay in place?

yes, you can solder the chip directly into the board, the socket is just there incase you fry/break the microcontroller so you don't have to desolder anything.

you also need to be careful when you solder it.  you can burn up a chip while soldering it if it gets too hot, i've never heard of anyone actually doing it though :P

what!?! ive heard of tonnes of people who have fried their chip from bad soldering...

another reason for the socket is so that you can use the same chip for more than one robot ;D

people i know seem to fry things installing them backwards or giving them too much current/voltage, not soldering lol

but still, my friend that im teaching electronics to, kept holding the soldering iron on there for too long..

you got that smash

and over heating is a common with noob soldering

and is common way of destroying a chip :D

i also don't solder many chips.  having good soldering equipment helps too.  having a nice iron that heats well makes soldering easier.  i remember starting out using an iron that would never get hot enough, nothing but cold solder joints
