Notes:
1.) Typical switching speed is measured from 10% to 90% of detected RF voltage driven by a TTL compatible driver. Driver output
parallel RC network uses a capacitor between 390pF – 560pF and a resistor between 150Ω – 220Ω to achieve 50nS
rise and fall times.

Assembly Considerations
Cleanliness
Chips should be handled in a clean environment free of organic contamination.
Electro-Static Sensitivity
The MASW-004100-1193 PIN switch is ESD, Class 1A sensitive (HBM). Proper ESD handling equipment and
procedures should be used.
Die 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.
Die Mounting
These chips have a Ti-Pt-Au back metal stack that can be die mounted using a gold-tin eutectic solder preform or
conductive Ag epoxy. Mounting surface must be clean and flat.
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.
Electrical 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 outer perimeter of the chip after placement to
ensure complete coverage. Cure epoxy per manufacturer’s schedule.
