Many small-component PCBs (printed circuit boards) are assembled today with no-clean solder pastes. No-clean solders speed up the manufacturing process by eliminating the need for cleaning circuit boards after reflow. The solder paste did not need removal and stayed in place without any detrimental effect to the function, performance and planned life expectancy of the…

Modern electronics are everywhere in our world, making life better for nearly every person on the planet. And today's electronic components are smaller and more complex than ever before. Manufacturers are squeezing micro components like CSP, flip chip, micro BGA and QFN packages into tighter spaces on the PCBAs. Low standoff components like MOSFETs and…

Modern PCBA cleaning is a challenge. The drive towards miniaturization has long been a goal within the electronics industry. As more advanced electronic applications are designed, which require increased functionality in a smaller package, manufacturers are looking for production methods which will result in a reliable device.The smaller, more densely populated circuit boards required for…

Water-soluble fluxes are also called organic acid (OA) fluxes. These are fluxes primarily composed of organic materials other than rosin or resin. Water-soluble fluxes and pastes provide good soldering results and bright solder joints because they are highly activated fluxes. This means they have good wetting action and a strong ability to prepare a clean surface for…

On the MicroCare Technical Data Sheets you will find a reference to the “non-exempt organic content.” This is the VOC content. You also can find this value on the flux remover can itself and on the SDS sheet.In most cases, VOC content is expressed in grams-per-liter which allows an accurate comparison across materials with different specific…

IPA (Isopropyl Alcohol) replacement cleaners are in high demand. Due to the COVID-19 outbreak, IPA for electronics cleaning is in very short supply. Since everyone from the medical industry to electronics manufacturers is using IPA for cleaning, it it quickly becoming a rare commodity. Many companies are now facing IPA shortages. Fortunately, MicroCare offers excellent…
