Purchasing and installing resistor...

post #1 of 11

Hello,

 

  I purchased this socket from Mouser.  I am trying to socket a 1/8w Vishay in a Bijou PCB.  The socket appears much bigger, by comparison, then the pcb cavity for the resistor.

 

 If this is the right socket, how am I to install the socket on the board?

 

Thank you for all your help.

You could always mount the sockets on another board and run jumpers to them. That's how I'd handle it. Not the cleanest solution, but it would be better than trying to enlarge the holes in the PCB.

I sacrifice 8-pin sockets (or better buy socket headers, which are strips of a bunch of pins in a FRN strip that you can hack up... same result but cheaper) when I need these little guys.

Putting these little guys in is kind of fiddly, please pardon my messy soldering.

 

I dont remember exactly which ones those are, but

from mouser should work with resistors that have thin leads.

These work as well.

You can either cut individual pins or cut to length and remove the pins you do not need (leave the end pins and remove the middle pins). a little pricey, but, easy to work with.

EDIT: i believe this is the type of strip nikongod is referring to in his post.

So I just have to purchase one of those and just cut the socket to get at the pins?  Then solder those removed pins to the pcb?

I've never even had luck with the SIP strips.  You can't cut them without breaking the last one in line and by the time you snip the leads off the ones in the middle, you're left with something very fiddly as nikongod says.  I finally settled on just using cut up DIP sockets.  A DIP socket is the only thing that has enough meat (plastic) on it to remain stable in most applications, IMHO.

What is the difference?

Which DIP would be recommended for the tiny 1/8w leads?

I think you'll find that most resistors will span one side of a DIP-8.  It all depends on the distance of the pads on the PCB, though.

Just for the record, the socket you ordered is a surface mount socket, meant to soldered down to a flat pad, not placed into a hole.

Interesting. I had pretty good luck with the SIP package. I used a razor and cut part way through on each side and was able to get a clean cut. For the middle pins, I did not snip them, rather, I just pushed them out from bottom. Of course the DIP packages are always seem to be priced better, so, that is also another key advantage of that solution.
