Roger,
the test board was supposed to be plated with standard Sn/Pb plating
(very common during 1970 -1975 time frame). So we learned of Bi
contamination of Sn/Pb solder through a manufacturing mistake. But
plating is plating except the thickness involved. Sorry that data was
not made available so as to calculate the % of various elements.
thanks.
