Hi, I am a newbie here and I am also very new to circuit boards. How do you solder the lead wire to the circuit board copper path after you have tinned the iron and inserted the component through the hole from the other side without damaging the board or the part?

Not quite the focus for this group, but it's an easy answer... Your iron should be clean and tinned, meaning it should have some solder on it already - not a big blob, but some. The tip should be large enough to transfer heat quickly enough, without overheating. Something about the same width as the copper pad you're soldering to is about right. Place the tip of the iron on one side of the pad so that it touches both the copper pad and the wire lead. Touch the wire solder to the OTHER side, so it does NOT touch the tip of the iron. When the pad and wire get hot enough to melt the solder, melt in enough solder to get an even fillet, then remove the solder wire and iron. That technique gives you enough heat to do the job, without too much heat or heating for too long. Note: do not assume that solder is a substitute for a mechanical joint. When soldering large wire-lead components, bend the leads over to hold the part in place before soldering. When soldering wires together, the splice in the wire should be strong enough to hold the wires together *before* you solder them.

It depends on the wattage of the iron. A temperature controlled iron is best. 25-40 W In order to solder, you need to heat both pieces. i.e. push the lead against the pad. Apply solder to the pad and not the iron usually on the opposite side that you are heating. --- In Homebrew_PCBs@yahoogroups.com, "Anita" <ginskia@...> wrote:

I would like to offer my services in soldering prototypes, under 100 units. I am certified as an IPC-610 and J-STD trainer, I certify others on how to solder. I currently have 6 years in a professional PCB board house. I am fully aware and trained in ESD precautions. Contact me if interested. Brian, CIT.

It would be most useful if you would include your location. ST
