why 60-40 solder?

I refer the honourable gentlemen to the following data

One of my old Popular Mechanics (maybe it was Popular Science) magazines I read back in the 1960s had an article about how to solder anything.Get a small round wire brush for your electric drill (drill motor) and load the brush up real good with solder.Apply the loaded up with solder wire brush to a piece of wood, plastic, whatever, and you can solder a piece of wire to the whatever.I never tried it out though. cuhulin

This is a joke, right? First you're telling us about nails made red-hot by microwaves, now you're telling us how to solder to plastic.

If it is a joke(s), then I guess the hard back book about the magnetron and my old magnazine I read about soldering anything are jokes.Page 103 in my January 2008 Popular Science magazine has an ad about Chrome Anything.The ad says, Now you can chrome wood, plastic, metal, even ceramic with no special equipment required.Seeing is Believing.Real mirror finish.Get your sample at

x ray spex anyone?

Multicore is now owned by Henkel, and the solder products seem to have been dropped, although solder pastes etc are still produced.

We buy our cored solder in from France.

But this isn't the same thing.

Chrome and other metals have commonly been applied to plastics. The Polaroid SX-70 is an outstanding example, but hardly the only one. Metal plating is usually done by applying copper layer to the plastic, then electroplating.

Soldering is not plating. Soldering consists of forming an alloy bond between two metals.

If you wiggle the connection. you have a lot better chance of making a connection with 60-40. First thing I think of.

Well, maybe I'm wrong. One way to find out.

About thirty years ago, I read an article in a motorcycle magazine.The article was about do not solder up wire connections.Article stated that vibrations can make those rigid soldered up connections break loose. cuhulin

Get a straight bar of lead and a gas torch and try to ''fix'' a rusted out floor belly pan on a 1966 Alfa Romero convertible car. Tell her I Love her. cuhulin

So what keeps the connection "connected", if not solder? Are the wires wrapped around a bolt and nut? That isn't very stable. What about wire nuts (which are commonly used in household wiring)?

huh ????

that solder has 37 % lead in it.!!!! and thats crap , i work in a company that uses exclusively 60-40 solder and we ship weekly 3500 pcbs a week to the eu . where u get your info ?

When the EU find out, how you get out of jail ?

Read this:-

Actually the importer is on the hook, not the manufacturer...

But, there are exceptions to the rule, I'm sure he fits one of them.

It is illegal to produce boards with lead, just check the internet on RoHS. It is allowed in military applications and some medical devices as reliability is lower.

I think it's perfectly legal to rework boards using lead/tin solder if the boards were originally produced with it and because of that you can still buy led/tin rosin fluxed solder.

Hmm.. I didn't realize that there were any regulations on leaded solder here in the USA. I just thought we got consumer grade crap that was manufactured for sale in the EU that happens to be ROHS compliant.
