dubka Posted July 10, 2007 Report Share Posted July 10, 2007 Anyone got any tips on getting it out of the C64 without damaging or bending the legs?Cheers,Martin Quote Link to comment Share on other sites More sharing options...
woozy Posted July 10, 2007 Report Share Posted July 10, 2007 Put a small flathead screwdriver under one of the short edges of the chip and lift it just a millimeter or so. Do the same thing from the other side. Keep slightly lifting each side until the chip is out of the socket.At least that's how I usually remove DIP packaged chips from sockets. Just be careful and you'll be OK.Slightly bent legs can usually just be bent back without any problems (just in case you're a bit heavy handed with the screwdriver).

midiboxxer Posted July 10, 2007 Report Share Posted July 10, 2007 The chip is normaly mountet in a socket. You can take a small screwdriver for removing it, better is an special claw for IC´s. You´ll get it in every electronic mailorder.greetz ::)Markus Quote Link to comment Share on other sites More sharing options...
Wilba Posted July 11, 2007 Report Share Posted July 11, 2007 DO NOT USE ANYTHING ELSE. These are so goddamn cheap that there's no reason why you shouldn't have one. Also, it's a good idea to use an extra IC socket when you plug SID into your PCB, as then it's a lot easier to remove while you're testing/building your MB-SID. Once it's all working, you can plug the SID in directly. Quote Link to comment Share on other sites More sharing options...
woozy Posted July 11, 2007 Report Share Posted July 11, 2007 But using a specialised tool is almost like cheating :P.Actually I knew about chip-pullers but it never occurred to me that they're cheap and easily available ::) (I put one on my shopping list now).

stryd_one Posted July 11, 2007 Report Share Posted July 11, 2007 Yeh it should be a challenge. If you can remove a SID with your big toe only I will buy you a beer! Quote Link to comment Share on other sites More sharing options...
midiboxxer Posted July 11, 2007 Report Share Posted July 11, 2007 Thats exactly the tool I thought about! Quote Link to comment Share on other sites More sharing options...
Therezin Posted July 11, 2007 Report Share Posted July 11, 2007 There's an IC puller in every single computer toolkit....Anyone ever needed to remove a chip from a PC? :P Quote Link to comment Share on other sites More sharing options...
stryd_one Posted July 11, 2007 Report Share Posted July 11, 2007 I have, but back then everything was through-hole and sitting in sockets... Actually, not unlike Wiba's SID :) Quote Link to comment Share on other sites More sharing options...
dubka Posted July 11, 2007 Author Report Share Posted July 11, 2007 Okay, sounds good BUT I don't understand the bit about the extra IC socket...Wilba - do you mean plug the SID into an IC socket and then plug that into the IC socket on the pcb?Confused,Martinps - I actually sent this original post 5 minutes after breaking the leg off an eprom in my Sequential Circuits Drumtraks whilst trying to remove it with a screwdriver. It was so wedged in and then, all of a sudden, it flew out across the table with legs bent all over the place. The breakage occurred trying to (carefully) bend the legs back. Luckily it was the chip with Cowbell and Cabasa. Still a bit gutted... Quote Link to comment Share on other sites More sharing options...
Jaicen Posted July 11, 2007 Report Share Posted July 11, 2007 Dammit.It's worthless now, I guess you better send it to me for disposal... Quote Link to comment Share on other sites More sharing options...
stryd_one Posted July 11, 2007 Report Share Posted July 11, 2007 hints:One screwdriver on each side if you must avoid using the correct tool - ALWAYS lift it straight up, never lift one side higher than the otherWarm pins before bendingNever bend oxidised pins, period. If they aren't shiny, no bendy.You can always solder wire (or a new pin if the IC is used with a ZIF socket) onto the bare metal scar where the pin used to be attached (it won't go deep into the ceramic, probably it will snap off at the edge of the ceramic if not further down the leg). Be quick or you'll fry it!I had to straighten the bent pins on my neighbour's P4 last week.... I swear I was panicking so bad!!! I must've warned him 100 times that I was in all likelyhood about to finish the chip off for good, either by static or by breakage :-\ But... it's good!

DavidBanner Posted July 11, 2007 Report Share Posted July 11, 2007 what a nightmare, those pins are sooo small and sooo numerous - I though I'd bent some pins on my 930D and got a cold sweat just thinking about trying to rebend them....

stryd_one Posted July 11, 2007 Report Share Posted July 11, 2007 Yup, and he'd 'peeled' it off from one side, so the corner pins were bent like 40 degrees out :o Quote Link to comment Share on other sites More sharing options...
TheAncientOne Posted July 11, 2007 Report Share Posted July 11, 2007 There is a home made tool for this job - I had to invent it for similar reasons, though the chip said "TRW" and had their kind of price tag.Take a wide bore hypodermic needle or a piercing cannula. Use a fine grinder or Dremel disc to cut it off square, (they have angled points). Put on your earth strap. Slip the bore over the pin and gently crank it straight, repeat as needed. Lecture miscreant about cost of chip, say "Uh-Oh!" a few times whilst doing the job to panic them. Some cannulas are full tubes with a square end - in that case a cork pushed onto the point is a good idea, then use the other end. My local piercing shop still doesn't believe what I wanted them for..... Quote Link to comment Share on other sites More sharing options...
aeiou42 Posted July 12, 2007 Report Share Posted July 12, 2007 I used a butter knife to take my sid chip out. Just slid it under and gently pulled, then switched to the other side. Just work very slowly and don't use a lot of pressure. But the best is to get a IC extractor. You know, I think even have one of them, but for some reason "butter knife" was what came into my head at the time. Quote Link to comment Share on other sites More sharing options...
stryd_one Posted July 12, 2007 Report Share Posted July 12, 2007 Nice tip mike, I never saw that before!...Lecture miscreant...LMAOJust slid it under and gently pulled, then switched to the other side.

You know, I think even have one of them, but for some reason "butter knife" was what came into my head at the time.Gotta watch out for that repeated side-side thing hey... that's a recipe for breaking a weak pin off... in the socket. Bad. Only a fool would do that. It took me I mean it would take hours to get the pin out. If you did it. Which I didn't. Honest, it must've been one of the other techs. ;D Quote Link to comment Share on other sites More sharing options...
