hi there,

A little bit of advice about IC holders please!

I'm modifying a circuit that has a very small 14 pin surface mount Op
Amp that I need to tap into 9to feed off into another circuit). I
reckon my best bet is to "piggy back" an IC socket holder onto the one
that is already on the circuit board (ie solder onto it) as this will
give me a nice stable platform & I can also use pins into the relevant
IC socket legs.


My problem is that this is quite a small op amp. I've measured the
pins...between pins 1-7 (ie one side of the 14 pin) the distance is
only 8mm in total. Does such an IC socket exist? If so where can I
source one from?

Many thanks in antcipation.

Why dont you use a proto-board instead ?

The board I'm tapping into exists physically inside a digital
"modelling" guitar....I've made a small circuit board to sit inside the
guitar too, but I need to tap of the main guitar cct board to feed off
to my board...the only way of doing this is to either solder some leads
onto the existing cicuit board (very fiddly & potential for
shorts/breakages) or as a preference piggy back an empty IC socket on
top & then i can insert pins into this to tap off the necessary pins.

The easiest (and usual) method for doing this is to solder wire wrap wire or
something similarly small to the existing pins, IC sockets for common
surface mount parts aren't available, at least not commonly. You may be able
to hack in a standard IC socket and use a different op-amp in a DIP package
though.

Or, if only a IC socket is needed, a Textool socket
will do your job, I'd reckon
