Hi Technos,

the fact that paste height is maybe not a relevant and worthwile factor to
measure has been brought up several times on this forum. My experience also
says that I will have the same acceptable joints whether using a 6 mil
stencil or a 5 mil one, if the paste deposits are uniform (nice bricks). But
if I write a procedure setting the control zone between 5.5 to 8 mils I will
get flamed by both the customers auditing the process and my bosses.

Is there any standard/handbook/specification that sets control limits for
the height of the paste after stencil printing? Or which prescribes other
measurable indicators for good printing?

I must mention that I only have an LSM that can measure the height, no
volume checking available.

Thanks,
Ioan
