If the previous type was working fine why did you change to another type of paste??

nc-smq92 had a problem with sticking to squeegee blades. 92j was suppose to fix that problem....

Why are you using 92J instead of 92H. Is it becuase you are doing bed-of-nails testing? If not, try 92H.

It's a bunch of test pins that the board sits on to get tested. HP is a popular supplier of this kind of machine.

Yes we are using a 7 zone and a ramp to spike. How do you handle your solder paste and what printing methods do you use?

Find out if they decreased the metal load in the new paste to solve the squegee drop off problem.
