I does depend on the level of technology of the PCB. RoHS-HASL for basic products and Silver Immersion for a flat finish, are my preferred.

Hi Jack, I once tried this finish ( without changing any process parameters ) and encountered wetting problems even in the first reflow process. It was thought as cheaper alternative to Ni/Au we use for planarity reasons. Heard of the same problems

What do you think about OSP ?

I think it might be the best choice for OEMs that only run one finish and practice JIT. (taking cost into account) For everyone else I think they will eventually run into trying to use them too long after they have been opened. But when you can run b

Typically, Sn/Pb solders are used to preserve solderability on leaded and leadless SMT components. Are other finishes (such as those used in PCB manufacturing e.g. Sn, NiAu, OSP's, etc.) frowned upon by PCB stuffers and their customers? I am intere

Hi, I understand that solder dipping of gold plated units (PCB or component lead) is not the ideal solderability test (leaching of gold in the solder bath being one reason). Would anyone have recommendations as to the ideal solderability tests for g

We use ENIG whenever possible, to the extent that we will try to talk customers out of Pb-free HASL until our keyboard punching fingers bleed. It's much more solderable than HASL and it's flat.
