(on unleaded) These solders don't flow as well, but they also contaminate easily. Hotter temperatures make this second factor a serious concern. If you're doing lead free, you have to have excellent flux or your iron will always be a mess, and you joints unpredictable. And once your tip goes black with lead-free, it's almost impossible to clean (and seems to just go black again straight away). The only solution I've found once that happens is very fine grade wet and dry paper, then re-tin it by sticking the tip in a blob of solder paste. I've also found that with lead free, cleaning the tip with a wet sponge is what starts it going black in the first place (probably other factors leading into it, too, perhaps too much heat). You have to be really careful with the sandpaper too because if you take that plating off the tip, it disintegrates in no time flat. However, once I'm on a run of the tip not going black, I can usually keep it shiny for a long time, but once it starts going black it's a real problem. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Peter Clifton wrote: The black is oxidation, probably due to leaving the iron switched on for excessive periods without use, or due to having the iron too hot. ack. If both conditions combine, the tip gets dull and unusable. (I personally try to use Leaded solder as much as I can). Did you ever try a quality no-lead solder like Balver SN100C, or Felder SN100+ ? Unlike the cheaper SAC alloys, these solders feel comparable to leaded solder. If it is badly oxidised, you need to clean the tip using some kind of proprietary tip cleaner. I had good experience with steel wool. If the tip repels the solder, give it a decent rub. Our new soldering stations by OKi come with a bunch of brass wool. Due to their heater concept, the tip temperature does not overshoot. In addition, they detect when the tip is in the cradle and reduce the temperature. At my place, these soldering stations are subject to daily use by students who do their first electronics projects. All I can say, is that the first set of tips still show no obvious wear after about a year. Probably others will be able to provide better pointers ;). (And will point out if I have made any errors in mine).

Most of the time though, when I'm soldering - I'm repairing existing equipment made with a leaded process, so I tend to keep leaded solder. Since I'm not doing production work, I can also get away with leaded solder for new work as well. I understand it is important to keep leaded and lead-free process stuff separate to avoid contamination - I'm not sure if that is a legislatory or process requirement though.

I own two SP-200 units, and really swear by them - even if you can't get truly tiny tip cartridges in that series. They are AMAZING irons for heavy work, as they are really powerful. The PSUs and irons sell for about £70-80 on Ebay second hand. My only objection: You use leaded solder. ;-) I guess we've got to live lead-free in this industry eventually, but I will hang on to Leaded whilst I can. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)

Re: gEDA-user: Drill baby drill
Two ways: To just add a hole, use the Via tool. Use Ctrl-h to make it unplated, and adjust the soldermask tenting by making the soldermask layer visible and using the clearance keys (k, shift-k). You can set the size by selecting it and typing :ChangeDrillSize(SelectedVias,=250,mil) Alternately, create a real symbol for your mounting holes, and a footprint that goes with it, that has the right size hole. Then you place it like any other element on the board. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: Drill baby drill
So the :ChangeDrillSize(SelectedVias,=250,mil) would appear to be exactly what I want, but it does not seem to change anything. I tried selecting the vias and entering this, and I tried entering this when I had the via tool active and then placing a via. Any thoughts as to what I am doing wrong?

gEDA-user: vertical toolbox in gschem
Hi,
I switched my gschem to have a vertical toolbox on the left, rather
than a horizontal toolbox on the top of the screen.
With wide aspect-ratio screens, this is a better use of display real estate.
Patch attached.
Regards,
Mark
