I would absolutely recommend assessing the Pattern Stencil Cleaner, Pattern in addition to the Misprinted Board Cleansing Handbook. It’s a great intro of Pattern Cleanser methods, available chemistry kinds, along with treatment aspects to think about. It will certainly give you various options to take into account when matching with your procedure and demands.
The drying out method you mention could require to be assessed if you are utilizing “store” air, dryed or otherwise. If you are utilizing store air, that’s well known for carrying compressor oil with the system, either by insufficient filtering or blow-by. Ko separators seldom do a great task of getting rid of the oil impurities.
I would certainly suggest either getting a fully committed cylindrical tube of “5.0” pushed air or nitrogen if you feel you have to dry out the pattern after the IPA cleaning method. Advancement Technology has a rather fast dissipation price and the additional drying might not be necessary.
This is not an uncommon procedure to see when cleaning a pattern. It is necessary to not abuse utilizing IPA during the bottom side cleansing of the pattern. Pattern Cleaner if it gets in contact with the solder paste or permeates to the surface area of the pattern may impact solder paste residential properties detrimentally.
Cleansing the Stencil Cleaner with a complete clean down along with a last pushed air blast is acceptable as long as all apertures are devoid of any type of type of solder rounds along with modification after cleaning. A close assessment of the finer apertures is very important to ascertain if all the paste or solder rounds are eliminated.
There are automatic systems that clean the bottom-side of patterns along with pattern cleaning makers to efficiently wipe paste residues however hands-on methods are still made use of in several locations.
Some solder pastes relying on their chemistry might be far much better cleaned down with a cleaner containing a mix of solvents. It is furthermore much less complex to tidy up a pattern if cleansing is launched after the verdict of the printing treatment. Time enables the Stencil Cleaner to dry cleaning up more difficulty. Constantly a great suggestion to utilize a mask, guarding safety glasses along with handwear covers when doing this procedure.
