Rebonjour RedG, bon pour connaissance une autre aficionado  fran├žaise..J'habite au 6eme pres les St Germaine.

1/ Our use of the RoHS was as a transformer manufacturere and required 100% LF solder, pots, leads, components. A single leaded part of the chaine makes the procee leaded and contaminats the equipment eg the solder pot.

2/ The main issues we found were higher solder temp, thus all parts must withstand higher temp anf longer time, the reflow temp profiles are more critical.

The plastic  temp range of any solder  (transaition solid><liquid) depends on the mix, eg Sn/Pb 63/37 Eutectic has no plastic range and lowest T liq.

Finally there are reliability issues re plating of leads and tin whiskers, but these do not impact hand soldering hobby use.

3/ The LF solders include tin, Ge, Silver etc. and all of these heavy metals are not risk free to the environment.

4/ The Eu has REACH, RoHS, WEEE and many toher regs that apply even to LF solder.

5/ The use of Tin was restriced in USA by an old law that required proof that the tin is not from an African mine with conflict minerals.

Finally saw your other notes re soldering irons, we use Metcal SP-200 500kHz for large area, gr plane etc and found these far superior to the Hakko or any Chinese clones.

Full disclosure...my design for Raychem/Metcal ~ 1991

Bon Soiree,

Cool. When I first moved to Paris, I lived just off Boulevard Saint-Germain on Rue Saint-Guillaume :)

Just received the second of the JBC barrel cartridges that I ordered, which was out of stock. I now have the 0.8mm and 2.5mm, specs below. Like the 0.8mm cartridge, the 2.5mm came pre-tinned, but at first glance I think that it may work with the Neutrik XLR cups.

I've decided to make my own soldering station from gear that I have on-hand, and to use 1/2" plywood as a work surface. I want control over the height of the work surface, so I'm going to mount the plywood on the type of stand shown in the photo below.

These stands are used for filmmaking and still photography. They're rock solid, and the height can be adjusted from 60cm (24") to 115cm (45"). The mount that I'm going to use (photo below) consists of a steel plate and a stud that's 28mm (1 1/8") thick. The plate is screwed to the bottom of the plywood, and the stud is inserted into the top of the stand and locked down. In addition to giving me control over height, this will make the soldering station (basically the 1/2" plywood + plate) easy to stow away. The whole setup is highly portable. Because I already have the stand, the cost is a few dollars for plywood plus US$25 for the plate.

I'm satisfied that photo/video grip gear is built better than most of what's sold for soldering, and in some cases would do a better job, so I'll be using the articulating arms and clamps that I already have to mount components that need to be soldered.

Perhaps of interest to readers who are into photography or video, the stand has a standard Junior (28mm) female socket and the plate has a Junior male stud. This particular stand is often used in pairs to support a film camera on dolly track. It's also used to support a computer and/or monitor on a tethered shoot where the camera is connected to those devices via cable or wireless. The stand can just as easily support a soldering station. It's also perfect for mounting a light or light modifier relatively low to the ground. At 6.4kg (14lbs), with a footprint just under a meter and a load capacity of 36kg (80lbs), these stands are very stable.
