Preformas de aleación de oro
AuLTRA® ThInFORMS
Indium Corporation’s AuLTRA® ThInFORMS® are the ideal choice for die-attach applications. By utilizing a preform thickness of 0.00035″, the bondline thickness (BLT) is reduced, enhancing thermal transfer from the die to the substrate. This optimization boosts operational performance and efficiency in high-output laser applications. The packaging tailored for automated assembly of these preforms guarantees consistent success in the production process.

AuLTRA® ThInFORMS® Preform Shapes
Available in square, rectangular, and disc Indalloy®182 preforms with a thickness of 0.00035″. These preforms improve operational efficiency of high-output lasers by reducing voiding, solder volume, and wicking up the die.
Geometría
Guidelines for preform geometry can be derived from the die size. Generally, 90-100% of the die size will indicate the preform x and y dimensions. When it comes to thickness, AuLTRA® ThInFORMS® provide a thinner bondline, improving thermal transfer from die to substrate. The most critical attribute for die bonding application is flatness, but due to process constraints, fixturing can be difficult and time consuming. Allowing the die to float freely on the preform can be advantageous. If the preform is not flat, it can skew the die at reflow and fail, which is why processing is the key to preserving flatness.
Aleaciones
Indalloy®182 (80Au20Sn) ensures excellent performance and reliability for applications that require a high-melting die-attach solder. Indalloy®182 is typically chosen for its thermal conductivity, high shear yield, tensile strength, wettability, and resistance to corrosion.
Summary
Indium Corporation’s AuLTRA® ThInFORMS® are an excellent choice for die-attach applications. By using a preform with a thickness of 0.00035″, the BLT is reduced and thermal transfer from the die to the substrate is improved, increasing the operational performance and efficiency of high-output lasers. Packaging designed for automated assembly of these preforms ensures repeatable success in a production process.
