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

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

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 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

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?

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

Have you tried doing solder dip test on these components? Or a Leaching Test, to see if the solder catches on the termination ? I suggest you should try these tests.. Cheers Indy

we've received an inquiry if lead free solder for solder dips or surface mounting (cream solder) is available on a technical scale
