Won't Get Toiled' Again

摘要

When faced with an incomplete paste print on a newly delivered stencil, go back to basics and check for the real cause. It doesn't often happen that a stencil will arrive in the assembly area with blocked apertures, but it does happen (FIGURE 1) when waste from cutting is not removed, and can lead to an incomplete paste deposit. FIGURE 2 shows the desired results from laser cutting: apertures collected from the bottom of a laser-cutting system. It shows the range of sizes and the laser mark on the surface of the waste where the laser starts its cutting operation and ends the cutting track.
