dave windymiller Posted April 30, 2021 Share Posted April 30, 2021 Used lead solder that has a flux in the center as its easiest ! Alternatively, if you cant get lead solder or you want to embrace the latest ecological thinking, use lead free solder but again fluxed.

Phil McCavity Posted May 1, 2021 Share Posted May 1, 2021 There have been a zillion debates about this since the banning of lead in the UK and the impression we get is given the choice, electronics manufacturers and those in the trade would go back to using and selling lead if the law allowed it so as you are asking a simple question my simple answer is lead with rosin flux. Failing that you have no choice but to use lead free solder. Quote Link to comment Share on other sites More sharing options...

Craig Carr Posted May 1, 2021 Share Posted May 1, 2021 (edited) Hi David, the 60/40 solder that Dwain mentioned is the stuff I use all the time, absolutely fine. top tip....when you solder your multiplex plugs, plug a male and female together during the soldering process. if you accidentally overheat a pin when soldering the plastic will soften and the pin may no longer be straight and you may not be able to rejoin them, but keeping them paired together will keep the male pin straight when the plastic cools again. ask me how I know ?

I use XT60's and do the same. Very easy to get a wonky plug. D.D. Quote Link to comment Share on other sites More sharing options...
Tony H Posted May 1, 2021 Share Posted May 1, 2021 Any ideas where you can buy? Decent 60w soldering iron. Everything I find on the web are cheap chinese rubbish. Quote Link to comment Share on other sites More sharing options...
Don Fry Posted May 1, 2021 Share Posted May 1, 2021 (edited) I use one of these, 60 watt, comes with a load of different bits, accurate temperature control, nice silicone cable, seems well made. A clone of something. Chinese rubbish, unfortunatly. About £50 to £60 from memory. Edited May 1, 2021 by Don Fry Add photo Quote Link to comment Share on other sites More sharing options...
Brian Sweeting 1 Posted May 1, 2021 Share Posted May 1, 2021 I may be way off here but I thought that lead free solder was primarily for use in plumbing work. Quote Link to comment Share on other sites More sharing options...
Cuban8 Posted May 1, 2021 Share Posted May 1, 2021 (edited) When I was a PCB and equipment repair tech in the early 90's I tried the early incarnation of leadless solder - it was pretty hopeless TBH, but over the last thirty years things have moved on and the last stuff that I tried was fine.

BackinBlack Posted May 1, 2021 Share Posted May 1, 2021 (edited) Not so Brian, the use of lead, and other substances in manufactured items is restricted by RoHS. These regs do not however cover domestic/DIY use of lead solder. The use of lead based solder and components in plumbing was banned some time before the RoHS directives. RoHS stands for Restriction of Hazardous Substances. RoHS, also known as Directive 2002/95/EC, originated in the European Union and restricts the use of specific hazardous materials found in electrical and electronic products (known as EEE).

Engine Doctor Posted May 2, 2021 Share Posted May 2, 2021 I wouldn't use any of the lead free solders available its horrible stuff, doesnt flow as nice and needs more heat. Just my opinion. Multicore fluxed solder is a good all round solder. Any decent 60-40 Tin-Lead mix will be ok . Look for a weller 85W iron for soldering larger gauge wires and undercarriage wires.

Thanks for that, I appreciate that domestic is often different from commercial but that doesn't make buying some products any easier.

BackinBlack Posted May 2, 2021 Share Posted May 2, 2021 Traditional lead/tin solder is available from outlets like CPC Farnell, Rapid Online and no doubt EBay. Lead free solder takes some getting used to and wrecks soldering iron bits quite quickly. A 250g reel of good multicore tin/lead solder (like this Multicore Solder will last a very long time.

kc Posted May 2, 2021 Share Posted May 2, 2021 (edited) The Component Shop sell leadfree and old fashioned tin lead solder. Lots of other items we use as well. Reasonable postage costs too Edited May 2, 2021 by kc Quote Link to comment Share on other sites More sharing options...

John Tee Posted May 2, 2021 Share Posted May 2, 2021 Lead is banned in plumbing where potable water is carried in the pipe ( drinking water) other domestic uses ie gas are ok. john Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted May 4, 2021 Share Posted May 4, 2021 The more I look the more I find. 4-Max Soldering equipment and it's all leaded. Why did I ever think lead solder was banned? Why did I throw away a big reel of lead solder? ? Many years ago though. Steve Quote Link to comment Share on other sites More sharing options...

Frank Skilbeck Posted May 4, 2021 Share Posted May 4, 2021 I was just soldering a couple of MPX plugs onto lipos this morning, using lead free solder (all I had) and an 80 watt iron, no problems. Tips, do one wire at a time, make sure you have the heat shrink on first wire before doing the 2nd, tin both wire end and plug pins and as recommended above have male and female plugs plugged together.
