IC sockets |
|
|
Hi,
I'm a total newbie and I'll probably be asking a few dumb questions in the near future. So here's the first - I've got all the components and stripboard and I think I'm ready to go but I didn't get IC sockets. They're probably a good idea, right? Is there anything I should know about them? Just get them with the right number of pins? The only other thing I've built was a PAIA pedal and I did use IC sockets. Are they necessary though or just for someone sloppy like me?
Thanks |

You want to use sockets for trannies and chips. Its just good practice. Chips and trannies don't like heat so if your heavy handed on the iron its a good idea. _________________ "your stripes are killer bro" |

Quad Op-amp configurations (TL084, LF444) use 14 pin IC sockets. Things like the LM13700 dual transconductance amp uses 16 pin IC sockets. If you've got other IC's, but don't know the pin count, look at its datasheet and you'll usualy see a drawing of the IC with the pins all numbered. |

The main reason I use sockets is where the project involves buying some relatively exotic chips which I may one day want to use in something else. I solder transistors, and cheap, non-static-sensitive chips like 555s, 741s etc. basically to gaurantee connections and save my sockets! _________________ What makes a space ours, is what we put there, and what we do there. |

i use sockets for all my ICs, but not transistors. originally, it was to keep from damaging them by overheating... components are more heat-tolerant than they used to be, and my soldering hand has gotten steadier/quicker, but it's how i've always done things so i keep doing it. it's saved my butt a few times--i notice that i've soldered the socket the wrong way around; if it had been the IC it would have lost it's smoke. some folks (paul s. of MOTM for instance) are adament that sockets only add one more connection and one more point of failure, and i'm sure they're right.
i solder my transistors and diodes, but i'm still careful about overheating--typically, i'll stuff all the trannies, then go around the board and solder 1 leg of each one, then go around again and solder the second leg etc, to let 'em have time to cool in between.

Erm, if you've got the IC's, why not simply count the pins? |
