If you’re familiar with the PCB stencil printing process, you know that it takes great care and precision. Stencil printing requires the use of three main materials: a stencil, solder paste and a printer. The solder paste is spread over the printer to establish electrical connections with the PCB. Sometimes a squeegee blade is used to apply the necessary force to spread the paste across the stencil and onto the PCB. In order to keep your printing process running smoothly, you need to clean your stencil, boards and tools regularly. While you can attempt to clean them by using your everyday household products, that might not be the best option.
A man attempting to clean his boards before printing encountered this very issue. He asked, “What is the best solution for cleaning dust and debris from printed circuit boards? I currently use paper roll wipes, but upon inspection I still find particles on the boards.”
Mike Jones, Vice President of MicroCare and a specialist in the field of electronics cleaning and stencil printing, encouraged everyone that experiences this type of issue to get rid of the cheap paper wipes and switch to a lint-free presaturated wipe. “Presaturated wipes are desirable because they remove operator errors from the wiping process,” Jones said. “Every wipe is exactly the same, and carries exactly the same amount of solvent, so the cleaning can be very consistent.”
That is why MicroCare developed the MCC-MLCW MultiTask Surface Cleaner Presaturated Wipes. This product works to remove solder paste, flux residues, finger prints, uncured epoxy residues, light oils and grease from your surfaces before printing. Like Jones recommended, these wipes are lint-free and also won’t rip during use. The packaging has a unique “slam shut” design that ensures a long service life.
The Techspray 1608-100DSP IPA Presaturated Stencil Wipes are another great option for SMT surfaces. They can be used to remove all types of solder paste and other adhesives from screens, misprinted boards, stencils, tools and equipment. These wipes are comprised of 70% IPA and 30% ionized water, and are also lint-free. They are safe to use on plastics, have a two-year shelf life, and are non-ozone depleting. Having a dependable cleaning wipe at your disposal is important to achieve the best printing results and ensure maximum production.
