Applications
The MA4E2532-1113 Series SURMOUNT
TM Low
and Medium Barrier Silicon Schottky Ring Quad
Diodes are recommended for use in microwave
circuits through Ku band frequencies for lower
power applications such as mixers, sub-harmonic
mixers, detectors and limiters. The HMIC construc-
tion facilitates the direct replacement of more frag-
ile beam lead diodes with the corresponding Sur-
mount diode, which can be connected to a hard or
soft substrate circuit with solder.
Handling
All semiconductor chips should be handled with
care to avoid damage or contamination from per-
spiration and skin oils. The use of plastic tipped
tweezers or vacuum pickups is strongly recom-
mended for individual components.
The top sur-
face of the die has a protective polyimide coating to
minimize damage.
The rugged construction of these Surmount de-
vices allows the use of standard handling and die
attach techniques. It is important to note that in-
dustry standard electrostatic discharge (ESD) con-
trol is required at all times, due to the sensitive na-
ture 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 tech-
nology. Mounting pads are conveniently located on
the bottom surface of these devices, and are oppo-
site for the active junction. The devices are well
suited for high temperature solder attachment onto
hard substrates. 80Au/20Sn and Sn63/Pb36/Ag2
solders are acceptable for usage.
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 solder-
ing 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.
