  • The best presaturated wipes for circuit board cleaning

    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%  Techspray 1608-100DSPIPA 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.

    Both of these products can be found right here on the GoKimco website at an affordable price with fast shipping. GoKimco is a proud supplier of many other MicroCare and Techspray products, so be sure to check them out!

  • Why would you need canned air for circuit board assembly?

    Techspray 1671-10sIn 2008, a bowling alley employee was performing her everyday responsibilities.  A paper shredder needed cleaning and a can of compressed air seemed like the perfect tool to get the job done. However, this canned air did not have “nonflammable” in its label. The employee tilted the can and sprayed the liquid onto the shredder. The liquid turned into a gas which then ignited a fire, causing burn marks on her face.   Get more info on the incident from the Washington State Department of Labor & Industries posting.

    The incident prompted the US Department of Labor to issue a hazard alert to those that use canned air and to list safety tips to avoid the risk of injury or death. Canned air is not the same as the air you breathe. It consists of compressed gases that if used in a poorly ventilated area, could ignite a fire, as in the case of the bowling alley employee.

    Don’t be alarmed, though. You can eliminate the reality of facing a situation such as this one simply by switching to a non-flammable air can. In fact, this is one of the US Department of Labor’s main safety tips. Now that you know this is the safer option for you, it’s time to choose which one to go with. The Techspray 1671-10S is a great nonflammable option. It’s odorless, leaves zero residues and has a ten-year shelf life. With this product, you can properly clean your electronics and keep them working longer.

    The Techspray air duster can be used to clean a wide number of surfaces and is especially useful for circuit board assembly. It is also safe to use on plastic materials. The air removes microscopic contaminants, lint, dust and metallic oxide deposits before they build up and cause overheating or shortages. Having this nonflammable canned air in your workspace will ensure the safety of you and your projects.

    To give you an idea of the versatility of this product, you can use the Techspray 1671-10S on:

    • Audio/Video Equipment
    • Computers and Other Electronic Equipment
    • Fax Machines
    • Laboratory Instruments
    • Photo Equipment
    • Printed Circuit Boards
    • Printers
    • Surface Mount Devices

    Lastly, since we’re on the topic of safety, here are some tips on how to properly use your Techspray product:

    • Hold the can in an upright position while spraying
    • Never tilt the can more than 40 degrees or shake before or during use
    • Before spraying, press actuator to clear the valve of any liquid product
    • You can use the extension tube to remove dust in tight areas
    • Use short bursts to prevent cooling of can
