If all the equipment is ordered, what SMT line introduction they asked you to do? Pick the equipment implements the whole design of the line, so basically your project is done.

Maybe try SMT Research http://www.smtresearch.com We get custom Fuji nozzles designed and made by them. Jerry

out of curiosity what components on the PCBs required the design to go down to 2/2 mils specs?

Is there any designer here and recommend the best trace impedance calculator you think? thanks a lot!

There is no solution in above case, this is caused by the PCB design. There are no thermals on the pads connected to the copper poured area. So the other pad reflow first and lift the component.

Luckly u found the root cause :) Don't you use SPI or some inspection machine? To prevent the trouble can happen next time, in my opinion, U shoud have inspection tool or Stencil design change to increase amount of solder.

Pick and Place file is a plain text file that usually contains the placement coordinates together with package type and ref designators. CAD file contains all the information about the assembly - PCB and components/packages both text and graphical re

Haha, you got the point, use with free charge is a big part to decide how I make a choice. I'll try KiCad.

I am pretty sure, you are looking into the wrong spot. Your paste is too much, or your part has very inconsistent narrow leads(that includes wrong pad design as well.)
