Hi Folks,

I've found myself in a familiar position of having to solder some wires into a DIN plug. In the past I've worked through this on
a one-off basis, but I have a project that calls for soldering 20 plugs with 4 wires each. The problem is that I can't seem to
get the solder cup hot enough to get the solder to adhere before the pin melts the surrounding plastic. I'm hoping there's a
tried-and-true method out there for doing this, and I'm hoping one of you can tell me what that is :)

This is what I just tried:
1) Dab of flux on each bare wire end and a little in each solder cup.
2) Tin wires (works like a champ).
3) TRY to tin solder cups - solder seems to not want to stick - end up with a blob on the iron.
4) Insert wire into cup.
5) Apply iron to wire and cup simultaneously and feed in solder.

The first pin I tried I melted the surrounding plastic. For the next three it looked like the solder ended up sticking to the
perimeter of the cup (once I got a big enough blob) but I'm not sure if it ever got inside.

I'm assuming that there's a way to keep the solder INSIDE the cup and to create a nice joint. Any words of advice?

Thanks,

Jeff
