Electrodag 502
one component, ready to use
Electrostatic bleed for SEM non-conductive samples which require grounding.
502 is a combination of specially processed carbon particles in a fluoroelastomer resin system. It remains flexible over a temperature range of -40°C to 260°C and cures at room temperature. 502 resists oxidation and has good adhesion qualities. The diluent is methyl ethyl ketone (MEK) and has fluid consistency. Solids content is 12.6%. Maximum service temperature is 275°C.
|
The specimen mount surface should be clean and dry before application. Keep the container tightly capped when not in use and avoid breathing the vapor.

a reliable conductive ground path for SEM specimens
Air drying silver to make effective ground. Curable at room temperature and has high adhesion to any material. Surfaces do not have to be prepared prior to application and will adhere to such materials as polymer (phenolic) boards, ceramic, glass, metal, plastic and fiberglass. It should be mixed or spatulated well before using.
The container is offered in two sizes (15g and 30g) and is provided with an applicator brush. Silver flake grain size is an average of 80%, <1.0µm. Sheet resistance is 0.02 ohms per square @ 1 mil (0.001” = 0.025mm) thickness and is a function of the coating.

resistant to oxidation and retains measurement integrity over time
Gold paste is fast drying and useful for analytical analysis over time where a high signal is desired. The gold is in microfine form and contains organic binders and a solvent. Dries at room temperature. Not intended for permanent use, but for testing and temporary work. Resistance is about 30-40 ohms. Contacts hold down to very low temperatures (<-200°C), but are not permanent since this type of product has low mechanical strength. 75% gold content; sphere size <2µm, flake size <10µm. Maximum service temperature is 65°C.
Refrigerate for best life. Bring to room temperature gradually. Approximate calculated specific gravity 3.18gm/cc.

Graphite Aerosol
Forms a thin, uniform conductive surface when sprayed on the sample. Dries very quickly and can be used for low magnification imaging of un-conducitve samples.
Excellent adhesion to most plastics, glass and metals. Other applications are for use as a lubricant (use dry in vacuum systems) and for plating non-conductors.

Leit C Plast
carbon base, good conductivity, large specimens
LEIT-C-Plast™ is a conductive adhesive that can be molded. Because of its relatively heavy paste consistency, larger samples can be held stationery for long periods when mounted on an electrical conductive adhesive station for SEM studies. The plasticity is permanent. It is not affected by high vacuum conditions and shows no peaks in energy dispersive X-ray microanalysis.
|
|
Heavy specimens may also be prepared for viewing in an SEM using Tempfix™ (or the Glue Gun - see details in our non-conductive section) and LEIT-C-Plast™. First the specimen is fixed into place with Tempfix™ or the Glue Gun. Afterward, an electrically conductive bridge is made between specimen mount and specimen using LEIT-C-Plast™. It is not required to wait for drying because neither adhesive outgasses.
LEIT-C-Plast™ was originally developed for holding specimens on angled specimen holders.
The adhesive is offered in a roll form and is black. Flat plates are provided for working the material. May be applied with a spatula.

Two Types:
silver resin paste / liquid hardener: H-22 Epo-Tek® (100:4.5 ratio)
silver resin paste / silver resin paste hardener: H20E Epo-Tek® (1:1 ratio)
General Properties
100% solids, two component silver filled epoxy with a soft, smooth, thixotropic (becoming less viscous when stirred or shaken) consistency designed specifically for chip bonding in microelectronic and optoelectronic applications.
|
Excellent handling, extremely long pot life at room temperature for this electrically conductive silver adhesive. High speed epoxy chip bonding systems are suitable for very fast cures, such as fast circuit repairs. Can be screen printed, machine dispersed or stamped and can withstand wire bonding temperatures in the range of 300 - 400°C.
Silver Conductive Epoxy, H-22 Epo-Tek®
Two component, silver-filled epoxy system, consisting of a silver resin paste and a liquid hardener (100:4.5). It is a free flowing paste, 100% solids system characterized by outstanding high temperature properties as well as excellent solvent, chemical and moisture resistance. It has a long pot life and is fast curing at relatively low temperatures. Containing no solvents or thinners; it will not outgas. It can be applied by brush, spatula or hypodermic needle. H-22 can be useful for small angle cleavage in material science and semi-conductor applications.
Epo-Tek® silver content is 60% by weight of composition. Note: Mixing ratio for this product is 100 parts silver resin paste to 4.5 parts liquid hardener.
