Description
M/A-COM’s MA4FCP Series consists of Silicon Flip Chip PIN
diodes fabricated with M/A-COM’s patented HMIC process. This
diode is fabricated on epitaxial wafers using a process designed for
repeatable electrical characteristics and extremely low parasitics.
This diode is fully passivated with Silicon Nitride and has an
additional layer of Polyimide for scratch protection. These
protective coatings prevent damage to the junction during
automated or manual handling. This flip chip configuration is
suitable for pick and place insertion.

Applications
The small 0315 outline and low 0.085 pS RC product, make the
device useful for multi-throw switch and switched phase shifter
circuits requiring < 20 nS switching speeds up to 18 GHz operating
frequency.

Total capacitance is equivalent to the sum of junction capacitance Cj and parasitic capacitance, Cp.
Series resistance R
S
is equivalent to the total diode series resistance including the junction resistance Rj.
Rs and Cp measured on an HP4291A with die mounted in an ODS-186 package.
Steady-state thermal resistance measured with die mounted in an ODS-186 package.
Assembly Considerations
The following precautions should be observed for successful
assembly of the die.
Mounting Techniques
These devices were designed for insertion onto hard or soft
substrates with the junction side down. They can be mounted
with electrically conductive epoxy or with a low temperature
solder preform. The die can also be assembled with the
junction side up, and wire or ribbon bonds made to the pads.
Cleanliness
These chips should be handled in a clean environment. Do not
attempt to clean die after installation.
ESD
These devices very susceptible to ESD and are rated Class 0
(0-199 V) per HBM MIL-STD-883, method 3015.7
[C = 100 pF
±
10%, R = 1.5k
Ω
±
1%]. Even though tested die
pass 100 V ESD, they must be handled in a static-free
environment
Solder Die Attach Using
Electrically Conductive Ag Epoxy
and Solder
These chips are designed to be inserted onto hard or soft
substrates with the junction side down. They should be
mounted onto silkscreened circuits using
Electrically
Conductive Ag Epoxy, approximately 1-2 mils in thickness
and cured at approximately 90 °C to 150 °C per
manufacturer’s schedule . For extended cure times >30
minutes, temperatures must be below 200 °C.
Sn Rich Solders are not recommended due to the Tungsten
Metallization scheme beneath the gold contacts. Indalloy or
80 Au/20 Sn Solders are acceptable. Maximum soldering
temperature must be <300 °C for <10 sec.
General Handling
The protective polymer coating on the active areas of these
devices provides scratch protection, particularly for the metal
airbridge that contacts the anode. Die can be handled with
tweezers or vacuum pickups and are suitable for use with
automatic pick-and-place equipment.
