Solventless Under Stencil Cleaning | 4 February, 2009

Has anyone any experience of using completely dry under stencil cleaning. I have recently been sent some information regarding Micro�Wipe� FP cleaning rolls. The claims about their performance are pretty good, but then what are they like in reality? Anyone tried these or similar? We currently use DEK platform screen printers.

Hi,

It depends on the stencil thickness, aperture size and the component footprint. For exampl if you have a PCB with QFP,CSP,QFN & BGA parts then this underwiper is not useable because you will still find solder cream deposits in the apertures after cleaning on QFP and BGA and it is considerabally high. Do analyze your product range in advance.....
