Customized Gold Tin Alloy Preform Ribbon Preform Solder Tab
Product Description
Introduction: Precious metal solders represented by gold and tin
have a wide range of applications in the industrial field. This
type of solder has stable chemical stability, good corrosion
resistance, good mechanical strength, and good wettability, and is
widely used in the fields of high-performance and high-reliability
electronic packaging and brazing connections. The precious metal
solders provided by BOLIN® Berlin Electronics include gold
(Au)-based series, palladium (Pd)-based series and silver
(Ag)-based series.
80Au/20Sn has a melting point of 280°C (556°F) and can be made into
solder preforms to address various options for specific
applications. Gold-tin solder preforms are typically used where
high melting points (over 150°C), good thermal fatigue properties
and high strength properties at elevated temperatures are required.
It is also used for properties that require high tensile strength
and high corrosion resistance without melting during the subsequent
low temperature reflow process. The alloy is also suitable for
fluxless soldering. Based on these, gold-tin solder preforms are
the best choice for die attach, especially on some high-power
devices.
Material Features
1. High temperature strength, high melting point solder;
2. Corrosion resistance;
3. Compatible with other precious metals.
Size selection
The preform size can refer to the chip size. Usually the dimensions
X and Y of the preform are 90-100% of the chip size. Regarding
thickness, thinner bond lines are desirable without sacrificing
reliability. The most important thing for die attach applications
is the flatness of the solder preforms. Due to the limitations of
the process and fixture, it is difficult to completely fix the
chip. The chip can be allowed to float freely on the preform by a
small amount. If the preform is not flat, it will tilt the chip
during reflow and fail the soldering, so keeping the preform flat
is key.
