The biggest factor is the selective solder machine. Do you want to know the minimum distance that all selective solder machines can handle with no difficulty? If so that will be a fairly large distance. If you are designing for in house boards then y

I did not read through this but hopefully there is something of value here: https://www.smtnet.com/library/files/upload/Design-Rules-Selective-Soldering.pdf

Dears, I would like to aks you, about minimal distance between solder pads for THT components for selective RoHS soldering. Is there some standarts, where I can find this information? Enclosed is draft, what I mean. Thank you very much for your suppo

One thing to consider is the length of the leads protruding from the solder side of the PCB will have an effect. Longer leads will be more prone to bridging than shorter leads with the same spacing.

If someone can find a RoHS specific standard I would be interested. IPC-2221 nor 2222 separate leaded from lead free (that I could see). Charlie

Here is the IPC Standards Tree [ http://www.ipc.org/4.0_Knowledge/4.1_Standards/SpecTree.pdf ]. The design standards that you ask about are over on the right side. I'd guess that the following standards would be a good starting point: * IPC-2221, "

What type of coating is used on the Vitronics selective solder nozzles? Any help?

We do not use a Victronics selective solder but we you activ8 102 stainless steel flux from worton metals for our nozzles. Hope this helps.

what does nitrogen do to assist the selective soldering process?
