Dear Rick , thanks for your reply. It is very helpful. I'll get chance to try the Ensolv in a lab next week to see if we can remove the paste residues. Thanks again

I have worked with Chrys Shea for a number of years. She has written a few white papers on SPI that may be beneficial to you. Here is a link to her website; http://sheaengineeringservices.design.officelive.com/default.aspx

I realize that I wrote wrong. Sry The stencil of 0,1mm of thickness is printing 45% more volume. I know this becouse the SPI is setup with the stencil gerbers and the messurements have a median of 145% of volume. what do you mean with excesive sold

Occasionally when circuit boards are manufactured, there may be issues with solder mask coverage. It is not uncommon to re-run back through this process to fix missing or thin areas. This can causes the traces to become higher which in turn raises th

OSP finish is the big issue here. You almost can not get 100% coverage solder on OSP with 1 over 1 aperture stencil. Reconsider solder coverage requirement in this case. Check your peak temp in profile may help a little.

Hi DucHoang, Thanks for your response - Understanding that OSP will have more surface resistivity which does not allows the solder to flow on the entire pads. Let me check peak & revert back sooner.
