This used to be done with a hot-oil soldering method in the old days.
However, I don't know if it can be done with SMT.

Subject: [TN] Buss Bar Attachment Method

Greetings,

We have an application where we will be attaching a buss bar that is 6
inches in length X .50 inch wide X .125 inch thick to the surface of our
PCBA. The buss bar material is currently spec'd as full hard copper and
is tin-lead plated.

The .50 inch width side of the buss bar will be the surface soldered to
the PCBA.

My questions to you are

1) What process would be used to solder this bar to surface of the PCBA?

2) What plating options would be recommended other than tin-lead for
this buss bar?

The end use application for this will require that it handle 1000A of
current in a worst case scenario.

Thanks in advance,

John Bauer
