Be careful if you use Ni/Au. The "black pad" phenomenum can be crippling. We moved from Ni/Au to OSP because of it. I also don't want to return to the lack of flatness of HASL.

Several online PCB fabrication quote forms offer SMOBC as a surface finish along with HASL, Ni/AU, etc. How does one specifify SMOBC for traces and untented vias, and elctroless Ni/Au for smt pads? Are these processes mutually exclusive? Or can I g

Will the gold from some Ni/Au surfaces make the solder joints appear dull and a slightly rugged on the surface ? Does anyone have any experience with this ? Thanks !

Is anyone has experience on problems with press-fit on Ni/Au board finish. Connectors pins are SnPb finished. I am particulary interested by experiences or documentation in very agressive environmental conditions (avionics or space buisness) Thanks r

Anyone knows if there are some issues when you solder Silver finish components on Ni-Au finish pads with Sn/Pb/Ag solder paste (Indium)? (I must use components with silver finish) Thanks

We have a simular problem with Ni/Au; especially whith pcb thickness more than 1.8mm. Note: These boards have been through reflow process also. 1.)Is there a maximum board thickness where it would be almost impossible to get a decent hole fil? 2.)Wi

Hi, Our engineering board has to decide which technology is better for the hand soldering of the SMT components: HASL or Chemical Ni-Au. We have an automatic line for SMD assembling and our experience shows us that for this automatic line is better

If its Ni/Au and there is no wetting then it should be there you have everything else shown.

Welcome Bob, HASL stands for "Hot Air Solder Level" and is the final finish the raw boards guys place on the solder pads on the PCB. There are two popular raw board finishes, HASL which is a solder finish and NiAu which is Nickle Gold, and is a Gol
