Re: RoHS question
Jim,
There is a raft of information on tin whiskers at one of the NASA sites: https://nepp.nasa.gov/WHISKER/index.html Some really great (scary) photos
As you can see on the NASA site, there actually

Re: RoHS question
Yes, we're in violent agreement.
Unless you're a manufacturer, RoHS (or whatever your local flavour is) isn't
a problem.
Space vehicles are exempt from these regulations, I guess they figure

Re: RoHS question
RoHS isn't a requirement that applies to consumers, incl hobbyists who might tinker with the product. It applies only to manufacturers. We - hobbyists - can repair even brand new RoHS compliant gear

Re: RoHS question
RoHS doesn’t bother a lot of people, even if you’re repairing old gear where the tracks fall off if you look at them funny you’re still allowed to use leaded solder. They’re full of lead and

Re: RoHS question
Tony,

Re: RoHS question
Thanks Jim. That sorts out all of my questions and thoroughly answers them. I will stick with what I have as I have plenty to last forever.

Re: RoHS question
Thanks for the reply Tony. That is what I wanted to know as I have a lot of regular 60/40 and some 63/37 that ought to last me forever. I also see no need to overheat or burn up my pcb's when using

Received from Dave at 10/26/2020 23:23 UTC:
No, it's based only on the weight of the components that are expected to contain lead... in this case the solder used can contain only 0.1% lead.

Re: RoHS question
Ah yes, I did mean I still use the leaded stuff, maybe I should stop chewing it.
And at least in Australian, you can buy it easily enough and it’s $10/roll cheaper than lead-free, so yay for us

Re: RoHS question
I think you meant to type, "leaded" instead of, "lead free" - your 2nd link is to classic 60-40 Sn-Pb solder. Some of the early Pb free solders were genuinely unpleasant to work with, enough so that

Re: RoHS question
It doesn't really matter what the item is, the lead (or whatever) percentage
is applied to each material used.
So the cable is made of copper, steel, solder, a few different plastics and

RoHS question
I bought some USB cables and noticed the RoHS sticker on them and never really read much about the standard so I have a few questions. It states something about 0.1% lead is allowed but in the case of

Re: Flux Pens
I think they're trying to say the flux residue can be removed with just water instead of requiring solvent cleaning. It's equally likely that it's just a spelling error ;-)

Re: Flux Pens
RS deliver worldwide, but the shipping might be expensive outside the UK. Other distributors sell Ersin products.

Re: Flux Pens
Thanks Harvey,
? I have a bunch of the Kester 186 RMA flux but I think it is the "no clean". I may look for a refillable pen with the 186 already in it and go from there.

Re: PCB through hole activation for copper plating
The problem was not lack of solder inside the eyelet, the component leads soldered fine with solder filling up the eyelet. It also soldered well to the bottom layer.
Once the eyelet channel filled up
