How to socket BX24? - harrybstoner - Aug 16 23:16:00 2005
Had a bad day here. I soldered all the components to my PCB today and
tried it tonite. But the BX24 did not boot up properly. Most likely
due to the fact that I used a machined-pin socket, and the BX24 pins
don't fit properly in the socket (literally a square peg in the round
hole problem).
I haven't encountered a problem like this, as all other chips I have
socketed previously has the tapered pins and fit great.
So my first question is, how do you socket your BX24? Will a different
type work? Secondly, I'm not sure how to proceed. I really don't want
to unsolder the existing socket (I can see myself destroying the PCB
traces). Can I place a socket in the socket? In other words, is there
any way to adapt the BX24 to the existing socket somehow?
I will have to make a long drive to the electronics store tomorrow to
try and rectify this problem.
And to top it all off I realized I had an error in my schematic too.
But at least I can fix that.
Thanks.

Just put a socket with flat wiper style pins into your
round-pin socket. You may even solder the 4 corner pins if you want the
sockets to stay mated. Generally the real cheap sockets work fine.

Neither have I and it should work. Before you run off in potentially the
wrong direction I would suggest putting the BX-24 back onto your
breadboard and running some solid hookup wires from the socket to the
breadboard. I think you could get away with just 5 (pins 1,2,3,21,23)
and then try out your PCB. You may have an entirely different problem to
what you think it is.

Thanks Neil. That's the direction I was thinking.

Given that the Bx-24 is okay you may have a short or something that is
causing a reset or just a badly connected socket as you suggested
earlier. Again try adding jumper wires from the socket on your PCB to
your breadboard. That might help.
