Rt is the dynamic slope resistance where Rt = Rs + Rj where Rj =26 / Idc ( Idc is in mA ) and Rs is the Ohmic Resistance.
Handling Procedures
All semiconductor chips should be handled with care
to avoid damage or contamination from perspiration
and skin oils. The use of plastic tipped tweezers or
vacuum pickups is strongly recommended for individual
components. The top surface of the die has a protective
polyimide
coating
to
minimize
damage.
The rugged construction of these SurMount devices
allows the use of standard handling and die attach
techniques. It is important to note that industry standard
electrostatic discharge (ESD) control is required at
all times, due to the sensitive nature of Schottky
junctions. Bulk handling should insure that abrasion
and mechanical shock are minimized.
Die Bonding
Die attach for these devices is made simple through
the use of surface mount die attach technology.
Mounting pads are conveniently located on the bottom
surface of these devices, and are opposite the active
junction. The devices are well suited for high
temperature solder attachment onto hard substrates.
80Au/20Sn

temperature is 320 °C for 10 seconds.

Die Bonding
For Hard substrates, we recommend utilizing a
vacuum tip and force of 60 to 100 grams applied
uniformly to the top surface of the device, using a
hot gas bonder with equal heat applied across the
bottom mounting pads of the device. When soldering
to soft substrates, it is recommended to use a
lead-tin interface at the circuit board mounting pads.
Position the die so that its mounting pads are
aligned with the circuit board mounting pads. Reflow
the solder paste by applying Equal heat to the circuit
at both die-mounting pads. The solder joint must Not
be made one at a time, creating un-equal heat flow
and thermal stress. Solder reflow should Not be
performed by causing heat to flow through the top
surface of the die. Since the HMIC glass is transparent, the
edges of the mounting pads can be visually inspected
through the die after die attach is completed.
