Solder Fortification® Preforms

Solder Fortification® Preforms are rectangular-shaped pieces of alloyed metal that do not contain any flux. The preform is added to a deposit of solder paste using standard pick and place equipment. Since the alloy for both the preform and the solder paste are the same, the preform will reflow at the same temperature as the solder paste, with the solder paste providing the necessary flux. The preform increases the volume of solder above what could be achieved with just solder paste, especially for applications using stencils with a pitch of 0.3mm or less.

Indium Compounds

Indium Compounds

The indium compound that is widely recognized today is indium tin oxide (ITO), a transparent conductor that is essential for building flat panel displays and touch sensors. TVs, computer monitors, tablets, and smart phones all use ITO to enable the switching of pixels and to register touch events. In fact, ITO applications dominate the use of all indium across the world today.

However, other indium compounds such as indium acetate and indium oxide also play important roles across various high-tech industries.

Indium Compounds Products

Indium Acetate

Indium Acetate Powder

Indium acetate is a precursor to InP quantum dots. It is a white powder that is freely soluble in mineral acids and consists of needle-shaped crystals, which decompose to indium oxide upon heating.

For more information about Indium acetate, please download our product data sheet.

IndiOx®

Indium Oxide Powder

IndiOx® (indium oxide or indium sesquioxide) is a yellow-colored powder. It is a stable ceramic-like material that is insoluble in water. IndiOx® is an n-type semiconductor and thus can be used as a resistive element in integrated circuits. It also is used to form heterojunctions with materials like p-InP, n-GaAs, n-Si, and other semiconductors.

For more information about IndiOx®, please download our product data sheet.

IndiOx® Type T (Target-Grade)

Indium Oxide Powder

IndiOx® Type T (indium oxide or indium sesquioxide) is a yellow-colored powder. It is a stable ceramic-like material that is insoluble in water. IndiOx® Type T is an n-type semiconductor. The particle morphology of Type T (target-grade) indium oxide is optimized for powder compaction to product high-density ITO and IGZO sputter targets. High-density targets result in superior sputter deposited layers on glass and plastic substrates. The higher specific surface area, coupled with a smaller primary particle size, provides sputter target manufacturers with a valuable variation when optimizing the ideal composition of the sputter target, and ultimately the device performance in the display electrodes or TFT transistors.

Indium Tin Oxide (ITO)

Indium Oxide Powder

Indium tin oxide (ITO, or tin-doped indium oxide) is a mixture of indium(III) oxide (In2O3) and tin(IV) oxide (SnO2), typically 90% In2O3, 10% SnO2 by weight. In powder form, indium tin oxide (ITO) is yellow-green in color, but it is transparent and colorless when deposited as a thin film at thicknesses of 1000-3000 angstroms. When deposited as a thin film on glass or clear plastic it functions as a transparent electrical conductor.

Of the various transparent conductive oxides (TCOs), ITO is considered the premium TCO, having superior conductivity and transparency, stability, and ease of patterning to form transparent circuitry. ITO is used in a number of display technologies, such as LCD, OLED, plasma, electroluminescent, and electrochromatic displays, as well as in a number of touch screen technologies.

These sputtering targets consist of gallium, indium, zinc, and oxide. GIZO or IGZO is the most attractive material for the flat panel component industry regarding emerging OLED displays, as it provides superior mobility for the thin film transistors that control the display pixels.
