Glass Transition Temperature (Tg)The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.

Specific GravitySpecific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Spheroid ToleranceThe allowed % that a solder ball (solder sphere) can divert from being perfectly round and spherical. We take one lot of solder spheres and divide it into 4 smaller lots. Each lot is then checked with advanced visual inspection systems. If even 1 ball is out of spec, the entire batch is scrapped and reworked!

Temperature ResistanceTemperature resistance is the maximum temperature that the material or product can withstand for a period of time. The temperatures listed should be considered as guidelines for an operating temperature of about 30 minutes. Typically, the material can withstand much longer times at temperatures about 20°C lower and can withstand much higher temperatures for short, intermittent times.

Thermal ConductivityThermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance. Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
Thixotropic indexThixotropic Index is a ratio of a material s viscosity at two different speeds in Ambient temperature, generally different by a factor of ten. A thixotropic material s viscosity will decrease as agitation or pressure is increased. It indicates the capability of a material to hold its shape. Mayonnaise is a great example of this. It holds its shape very well, but when a shear stress is applied, the material easily spreads. It helps in choosing a material in accordance to the application, dispense method and viscosity of a material.

UL 94 RatingThe UL 94 standard classifies plastics according to how they burn in various orientations and thicknesses. From lowest (least flame-retardant) to highest (most flame-retardant): HB: slow burning on a horizontal specimen; burning rate particles allowed as long as they are not inflamed. V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed. 5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole. 5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole.

VOC-Free (100% solids content)VOC means Volatile Organic compound. VOCs are evaporating molecules and are literally everywhere around us. Our scents are volatile organic compounds, most of the things that we smell are VOC etc. So what do we mean when we state that a product is VOC free? A VOC free product, according to the FTC is one where: 1)VOCs have not been intentionally added to the product. 2)The presence of VOCs at that level does not cause material harm that consumers typically associate with VOCs, including but not limited to, harm to the environment or human health. 3)The presence of VOCs at that level does not result in concentrations higher than would be found at background levels in the ambient air.
Volume ResistivityVolume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
