For more than 4 years, we were using Alpha metals, no clean 63/37 paste.
Recently we tried the Kester paste on our DEK printers. The printing
performance is far better than the Alpha Paste. So, we switched to Kester
FL250D no clean paste (63/37, 90%, Mesh -325+500 , VISC 1400-1800 ).


But, we are having serious unexpected problem on MPM printers. The paste
does not drop from the blades after the print stroke causing big voids on
the boards. We are scrapping quite a few boards due the misprints.


Is there any solution for this problem ? Some one suggested 'TEFLON' coated
squeegee blades.


Sincerely,


Rama Vemulapalli
