How to use an epoxy for underfill applications
By Ronald A. Miller, MS Underfill applications use adhesive compounds to fill the gap between a microchip package and the printed circuit board (PCB). This is necessary because new types of chip packages, such as ball grid array (BGA) and chip-scale packages (CSP), are surface-mounted — meaning solder balls attach the bottom surface of the…
New Grip Tape gives tools and devices a non-slip surface
Dropped objects are a concern at any job site. Now it’s possible to avoid the accidental slips or drops of a cell phone, tablet, and other tools or devices, thanks to new Grip Tape from CatTongue Grips. The company has taken the power of its “GRIPTION” product, typically used for cell phones, and transformed it…
New thermally conductive potting compound resists high temperatures
Master Bond Supreme 121AO is a NASA low outgassing approved epoxy suitable for bonding, sealing, and potting applications. Featuring a high glass transition temperature of 200 to 210° C, it resists temperatures up to 550° F. This system exhibits an element of toughness, and is not as stiff as conventional epoxies that withstand extreme temperatures.…
Which adhesives are thermally conductive?
By Ronald A. Miller, MS Adhesives are made from organic polymers and, as such, are inherently thermal and electrical insulators. The thermal conductivity of polymers is typically between 0.1 and 0.5 W/m-K (watts per meter kelvin). In comparison, steel has a thermal conductivity of about 40 W/m-K and copper is about 400 W/m-K, when measured…

Which adhesives are biocompatible?
By Julie Miller Exceptional care is taken in choosing biocompatible adhesives — a category of adhesive products that are considered safe to use on or within the human body. These specialty adhesives are biologically inert, which means they produce no toxic response or interaction when in contact with human tissue or bodily fluids. Biocompatible adhesives…
