Do any of you good fellows know a good instruction manual, on the net pretaining to tin dip techniques.

Hi Hannu, Just out of interest, are these big, heavy transformers, where the weight of lead in the solder will be less than 0.2% of the overall weight of the dipped part?

OK, granted, this is not exactly your hi-tech SMD production but pertains to lead-free so I'll post this anyway: Can anybody share their experiences on lead-free dip soldering of transformer terminals? I have not done any testing myself but have see

Hi Hoss, I was speculating - there are others out there with more experience in this field than me, who may know the definitive on this. I've heard rumours on transformers but nothing concrete. But I was guessing that the transformer (as a whole)

I do not mean big, heavy transformers but rather small ferrite core transformers, with ferrites in the range of EF16 .. EF40. The weight of the lead and its percentage of the total weight is not the issue here. We simply do not want lead-containing t

Hi Pat, And thanks for the sympathy :) This thing with ultrasonic transducer, is it something tried and trusted or is this a new idea for improving the wetting behaviour of leadfree alloys? This is completely new to me, can you please elaborate on

Rob, Are you hinting that the lead content of this component with dipped tin/lead solder would not be an issue with RoHS? If so, our understanding is that the legislation requires that the 6 banned substances cannot exist at greater than X% in any

Hi Hannu, You just gave a very realistic and practical view of the lead-free dilemma. The main reason that your coil coating doesn't get removed is because of the inability of lead free alloys to wet the surface and conduct the heat. Higher temperat

Hannu, First and for all I have a problem with your question "tried and trusted" for the simple reason that you are going to change too lead-free. Ultrasonic soldering or welding is not new, as far as I know it is only used applying the ultrasonic
