PELCO® Conductive Gold Paste

PELCO® Conductive Gold Paste

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. Sheet resistance is .02 to .05 ohm/sq @ 1 mil thickness. 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 3.18g/cm3.

PELCO® High Performance Silver Paste for ultra high vacuum 16047

PELCO® High Performance Silver Paste

Silver flakes in an inorganic silicate aqueous solution, specially formulated adhesive for demanding bonding applications such as:

  • High temperature up to 927°C (1700°F)
  • Ultra high vacuum - no hydrocarbon, no VOC's
  • Cryogenic temperatures (suitability depends on matching properties)
The excellent thermal and electrical conductivity, coupled with the absence of hydrocarbons, makes this product ideal for demanding specimen preparation in FESEM, XPS, ESCA, SIMS, Auger and other applications. PELCO® High Performance Silver Paste provides both high and thermal conductivity with a silver particle size of 20µm. Silver content >60% by weight. Cures at room temperature, but requires a 2 hour cure at 93°C (200°F) to achieve high conductivity and strong bond. Must be fully cured before using this product at cryogenic temperatures. Soluble in water to 260°C (500°F). Above this temperature it becomes almost insoluble.
For nonconductive, high temperature adhesive try Product #16026.

Leit C Plast Carbon Conductive Paste that can be molded

Leit C Plast™

carbon base, good conductivity, large specimens
LEIT-C-Plast™ is a conductive adhesive paste that can be molded to provide conductive paths to larger non-conductive samples when mounted on a specimen holder 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 a 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.
