Do you guys still solder using the old way or did you turn to lead-free soldering?
I'm doing the latter and I'm okay with it. Flow is a bit slower but the idea of reducing the lead buildup in my body is nice. Oh, the smell is also less pleasant, I've grown to love the typical scent of resin that doesn't appear to be present in the lead-free solder I'm using.
I've nevery really done any research if the lead-free solder is any different of quality.
Lead-free soldering
Re: Lead-free soldering
Oh, one thing I have noticed is that I often get this 'cold joint' effect, or whatever it's called. You know, when the solder ends up being fuzzy instead of shiny. With regular solder it's easy to prevent but with the lead-free solder, it happens most of the time. Same temperature (I think I'm using over 400C but can't check right now).
Re: Lead-free soldering
I have noticed a lot of fuzzy on my STF board. Checked the solder and it’s lead free.

I just thought it was poor quality solder or my rubbish soldering.
Re: Lead-free soldering
I tried a few brands of lead-free a few years ago, I don't like the stuff. It never seems to "flow" properly. It went from a blob which looked awful, so I turned up the heat to get it melt better, and it just burnt and made things worse. I'm never convinced even when it looks good that is actually melted on the PCB either.
I think as well, your supposed to use lead free pcb with the lead free solder. I can't remember but I don't think they "mix" well. Really we are using all 80s leaded stuff so trying to mix lead free with it all just isn't going to end well.
I'm all for lead free, don't get me wrong, but I just don't want to take the risk in using it.

Re: Lead-free soldering
Never really paid a great deal of notice to it but have noticed the variation in temperatures required for good soldering.
For instance, the lead free I'm using right now (was a freebie and lots of it) melts nicely at 270 - 300C but try it at 400 and it's more likely to etch away the board and I get more dodgy joints.
Whereas the last stuff I used had to be set to 400C for consistent joints.

If it ain't broke, test it to Destruction.

Re: Lead-free soldering
Still using lead based, mostly because I got a massive roll for free a few years back. About 370C seems to be the butter zone for me.
Collector of many retro things!
800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...

Re: Lead-free soldering
I'm Swedish, leaded would be illegal I solder at around 320-340 with the lead-free stuff I have and all my joints are always amazing

Re: Lead-free soldering
wow really ?
Can you list which part/brand you are using please ?

Re: Lead-free soldering
Hmm - actually it seems I overdid that comment a bit, sorry. My local electrokit company has the following statement regarding leaded solder:
So for most of my personal use I could get away with using it I guess.According to the EU Environmental Protection Directive ROHS, lead may not be used in the manufacture of electronics to be placed on the market. It may be used for repair of equipment put on the market before the directive came into force, and there is no prohibition for use for prototypes and experimental purposes.
Will do as soon as I get back from these two weeks of crazy business travelling ...
The same company (Electrokit) btw has this statement on lead-free solder:
A lead-free soldering gets a gray-matt surface that can look oxidized.
Re: Lead-free soldering
That is VERY reassuring.A lead-free soldering gets a gray-matt surface that can look oxidized.
