toneburst Posted October 5, 2006 Report Share Posted October 5, 2006 I've done a very silly thing:I've managed to damage one of the holes in the DIL socket that accepts a leg of the SID chip, in my SmashTV SID board. I, very stupidly pushed one of the probes in there a little too hard when I was testing the voltage, and now the metal contacts have been bent back so that they won't grip the leg of the chip properly. I haven't tried inserting the SID yet, but I think it's unlikely it's going to work. Now, I can't imagine anyone else has been this stupid, but can anyone, off the top of their heads, think of anything I can do to remedy the situation, short of desoldering and replacing the DIL socket? I've had a bad experience already desoldering something from one of these boards, so if I can possibly avoid having to attempt it again.....Alexhttp://www.toneburst.net Quote Link to comment Share on other sites More sharing options...
HL-SDK Posted October 5, 2006 Report Share Posted October 5, 2006 If it's a socket, you (if all voltage is good and you want to insert chip) can plug the socket hole with solder, and insert chip into socket while holding your iron on the solder to keep it molten. If you are pretty good, the chip will contact the solder that will contact the bent socket that will contact the PC board.desoldering 40 pin sockets doesn't sound fun :(You could always check voltage on bottom of board (I know... that wont check if voltage is going up to the chip, only to socket).

th0mas Posted October 6, 2006 Report Share Posted October 6, 2006 bend the socket pin back?Other than that, I find I always have to bend dip pins inwards to get them to fit in the socket, so maybe it'll just work? Quote Link to comment Share on other sites More sharing options...
modularkomplex Posted October 6, 2006 Report Share Posted October 6, 2006 You could tin the corresponding SID-Pin so it gets thicker and hass contact again. Mike Quote Link to comment Share on other sites More sharing options...
toneburst Posted October 6, 2006 Author Report Share Posted October 6, 2006 Ah, thanks for all the great ideas guys!I think, as th0mas suggests, I'll just try fitting the chip anyway, and see what happens.HL-SDKs idea sound scary- how heat-sensitive is the SID chip, I wonder? I'm not great with a soldering-iron, sadly, hence my previous post re. frying one of the solder pads on my Core board while trying to desolder the voltage regulator.Practice makes perfect, I guess. It also tends to make things broken, in my case ;-)Cheers,Alexhttp://www.toneburst.net Quote Link to comment Share on other sites More sharing options...
AndrewMartens Posted October 6, 2006 Report Share Posted October 6, 2006 When doing a voltage check on my board, I thought I damaged the wipers in the socket of my CORE in just this way. I sucked it up, stuffed the PIC in anyways. Lo and behold, it works!For my next project I'm going to use the good quality machined-pin sockets so that I never need to worry about this again :-) Quote Link to comment Share on other sites More sharing options...

cheater Posted October 7, 2006 Report Share Posted October 7, 2006 With some sockets this might work:1. dry out the broken pin's soldering spot with a solder sucker (can get one for $5)2. pull the pin out of the socket3. replace with a similar pin from a second socket4. solder and it's done!with some sockets, you'll notice you can push the pins out. machined pins don't let you do that, but if you heat up the socket carefully the plastic will let go and will let you put in a new pin (though that's nasty...)your best bet is to bend back the pin with an exacto knife.
