    Stencil Misprint Cleaner
 
STENCIL AND SCREEN CLEANING CLEANING OF MISPRINTS STENCIL UNDERSIDE WIPE CLEANING INSIDE THE SMT PRINTER
Solder pastes, SMT adhesives as well as thickfilm pastes, which are most commonly used during the assembly process, are typically applied via screens and stencils. Residues of solder paste and SMT adhesive that are left behind, especially in apertures can lead to print failure. For every stencil and screen cleaning application, ZESTRON offers either water-based MPC® cleaners or solvent-based cleaning solutions
Although cleaning the stencils considerably improves the print quality, misprinted PCBs cannot be completely avoided. Misprint cleaning is primarily intended for the removal of solder paste that has been applied incorrectly or has been smudged.

The effective removal of misprinted solder paste and adhesive can oftentimes become more cost-effective than their disposal. This is particularly true for double-sided populated assemblies, which due to their added value need to reintroduced to the process after cleaning.

In the case of already populated assemblies it is not only the removal of solder paste residues that is of importance, but also the removal of flux residues from the soldering process on the already populated side.

The misprint cleaning of PCBs can be easily accomplished by common stencil cleaning process.
Today, the cleaning of metal masks or stencils in the SMT printer is widespread. Automatic stencil cleaning ensures stable processes and the print quality is increased.

Underside wipe cleaning agnets usually get through the apertures and interacts with the solder paste. A non-compatible cleaner such as IPA (Isopropanol) can have an adverse effect on the soldering paste stability. During the use of IPA a significant amount also evaporates due to the high volatility.

However, a suitable stencil cleaner  should be implemented to remove the solder paste from the stencil underside, the amount used is reduced by 3 to 6 times compared to IPA. ZESTRON therefore offers water-based as well as solvent-based agents especially suitable for cleaning SMT stencils in the printer. These were developed and approved by leading SMT printer manufacturers such as DEK, MPM and EKRA
