Stencil Cleaning Machine

When manufacturing electronic assemblies, solder pastes, SMT adhesives or thick film pastes are printed or applied using stencils, pump print stencils or screens. Since solder paste residues and remaining SMT adhesives on the stencil surface and in the apertures can lead to misprints and sometimes hardening. A manual or an automated stencil cleaning machine is used to remove solder paste, SMT adhesives from stencils and PCB assemblies to ensure that the next assembly quality is not compromised.

Mectronics offers various stencil cleaning machine which can be differentiated by the number of chambers that are available for the various process steps such as cleaning, rinsing and drying. In single chamber, the cleaning fluid needs to be replaced in the chamber whereas in multi chamber , there are separate chambers for each process enabling the cleaning processs to take place in one or more chambers. Furthermore, stainless steel cleaning equipment has been proven to work particularly well. Steel stencils, fine pitch and nano coated stencils as well as screens are commonly cleaned in these machines.
