SP4T PIN Diode Switch with Integrated Bias Network
MA4SW410B-1
Assembly Considerations
The following precautions should be observed for successful
assembly of the die.
V 2.00
Mounting
These chips have TiPtAu back metal. They can be die
mounted with a gold-tin eutectic solder preform or electrically
conductive epoxy. Mounting surface must be clean and flat.
Cleanliness
These chips should be handled in a clean environment. Do not
attempt to clean die after installation.
Electro-Static Sensitivity
The MA4SW410B-1 Series PIN Diode Switch is ESD, Class 1
sensitive. The proper ESD handling procedures should be
used.
Wire Bonding
Thermosonic wedge wire bonding using ¼ x 3 mil sq. ribbon
or Ball Bonding using 1 mil diameter gold wire is recommended.
A stage temperature of 150 °C and a force of 18 to 22 grams
should be used. Ultrasonic energy should be adjusted to the
minimum required. RF bonds should be as short as possible.
Eutectic Die Attachment
An 80/20 Gold-Tin eutectic solder preform is recommended
with a work surface temperature of 255 °C and a tool tip
temperature of 265 °C. When hot gas is applied, the tool tip
temperature should be 290 °C. The chip should not be exposed
to temperatures greater than 320 °C for more than 20 seconds.
No more than three seconds should be required for the attachment.
Electrically Conductive Epoxy
Die Attachment
Assembly should be preheated to 125-150 °C. A Controlled
thickness of 2 mils is recommended for best electrical and
thermal conductivity. A thin epoxy fillet should be visible
around the perimeter of the chip after placement. Cure epoxy
per manufacturer’s schedule.
