thatguy Posted October 2, 2014 Report Share Posted October 2, 2014 What's the best way to remove a 6581 from the motherboard? I've read about using a heat gun, but I'd hate to damage anything. Quote Link to comment Share on other sites More sharing options...
latigid on Posted October 2, 2014 Report Share Posted October 2, 2014 A desoldering iron: a vacuum combined with a soldering tip. A reflow station might also work but it would be best to heaksink the chip while you do it. I got my SIDs NOS from Wilba, so no problems for me :).

raisinbag Posted October 2, 2014 Report Share Posted October 2, 2014 I havent done that chip specifically, but I use a desoldering tool from Hakko, it's the 808 (how could anything called an 808 be bad!!!!!) Its a great tool, you will wish you never bothered with Desolder Braids, or little pumps etc..... I think it is about $200, but if you can get yourself $50 chips with it, it will be paid off in no time. I originally got it to salvage all the compnents off a battery etched Poly6 PCB. You will never go back!!!!! Only other good option is a whole desolder station, but they can be expensive for a good one. Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted October 2, 2014 Report Share Posted October 2, 2014 Should be possible with a good high-powered desoldering vaccum pump and an iron set to mild temperatures (don´t heat up a pin for more than a few seconds, then vacuum it, repeat..., it may be a lenghty process). Which C64 model had the SIDs soldered to its mainboard? Many greets, Peter Quote Link to comment Share on other sites More sharing options...
Altitude Posted October 8, 2014 Report Share Posted October 8, 2014 i've seen a bunch of the originals with the chips soldered in the usa Quote Link to comment Share on other sites More sharing options...
thatguy Posted October 8, 2014 Author Report Share Posted October 8, 2014 Which C64 model had the SIDs soldered to its mainboard? Apparently there were two motherboard designs. Looks like the old one, used in all brown breadbin models, had the SIDs soldered to the motherboard. See http://ilesj.wordpress.com/2010/07/01/how-to-identify-c64-and-sid-model/ for more details.

Hawkeye Posted October 8, 2014 Report Share Posted October 8, 2014 (edited) Thx for your feedback, both of you! Haven´t seem them yet, but I was always harvesting for 8580s (new C64 model). Yup, bad karma! :-) Many greets, Peter Edited October 8, 2014 by Hawkeye Quote Link to comment Share on other sites More sharing options...
Blatboy Posted October 17, 2014 Report Share Posted October 17, 2014 BTW the Hakko 808 has been discontinued... now they have the FR300 http://www.hakko.com/english/products/hakko_fr300.html According to reviews it's better (minus one or two things) I just picked up one and have no complaints, except they are closer to $300 not 200 unfortunately. I would trust this thing to pull out old SIDs. Quote Link to comment Share on other sites More sharing options...
Altitude Posted October 17, 2014 Report Share Posted October 17, 2014 ^ Cool. Looks like the same design with some updates. The 808 is an outstanding piece of kit, all my braid and solder suckers are gathering dust because of that thing Quote Link to comment Share on other sites More sharing options...
KB9YEN Posted November 3, 2014 Report Share Posted November 3, 2014 Just my bit of knowledge on the subject in case anyone else has questions. Reflow stations are not meant for THM (through hole mount) components. Additionally they type of solder used when the C64 was produced takes more heat to reflow. Using hot-air/reflow station will produce excess non-localized heat that will damage the chip and other surrounding components. The absolute best way to remove any THM part is to apply a decent but not excessive amount of flux and use a desoldering tool. You can use an iron and solder sucker but that is far less effective than a good desoldering station. A less expensive alternative to the FR-300 is the Aoyue 474A++. In the Xbox360 repair world we use Aoyue products a lot because their rework station is far less expensive than others and so far the quality has been outstanding. My workbench consists of a Aoyue 474A++ and a Aoyue 968A+ Quote Link to comment Share on other sites More sharing options...
thatguy Posted November 3, 2014 Author Report Share Posted November 3, 2014 I ended up using one of these to desolder the SID: Quote Link to comment Share on other sites More sharing options...
