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.
