Solderpaste types have a big effect on print performance. Go to this link to see if the solderpaste you are using has been tested, see "Rheometric Pump Paste Tests" under MPM: http://www.speedlinetech.com/news_publications/application-notes.aspx?OnI

I have been confronted with a MPM with a rheometric pump head on and have not had much to do with these. It is giving varying results on the down line paste AOI and is not responding very much to changes in pressure, speed etc. It is a 16inch pump, w

The oxide layers are known as wetting inhibitors in component and PCB metallizations. The oxide acts as barrier that prevent the tin diffusion from happening. Besides, in corrosion studies, the role of salt residues -with Cl ion- on some metals is known as being promoters of oxidation or corrosion. On the other hand, most of corrosion studies with tin metallization are focused mainly on the corrosion resistance of tin alloys, but little has been done respecting to the influence of salts on tin metallization wetting. In this paper, a series of experiments was carried over to know the influence of specifically NaCl on BGA wetting given Head in Pillow (HiP) as result.

Head-in-pillow (HiP) is a BGA defect which happens when solder balls and paste can't contact well during reflow soldering. Package warpage was one of the major reasons for HiP formation. In this paper, package warpage was measured and simulated. It was found that the package warpage was sensitive to the thickness of inside chips. A FEM method considering viscoelastic property of mold compound was introduced to simulate package warpage. The CTE mismatch was found contributes to more than 90% of the package warpage value when reflowing at the peak temperature. A method was introduced to measure the warpage threshold, which is the smallest warpage value that may lead to HiP. The results in different atmospheres showed that the warpage threshold was 50μm larger in N2 than that in air, suggesting that under N2 atmosphere the process window for HiP defects was larger than that under air, which agreed with the experiments.
Precise lines are dispensed to fill an area on a heat sink. At the end of this video, you can see a demo of placing a glass slide on top of the dispensed material to see uniformity of the area. http://www.nordsonasymtek.com
