MA4SPS402
SURMOUNT^TM PIN Diode
RoHS Compliant
Rev V6
Handling
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.
Bulk handling should insure that abrasion and mechanical shock are minimized.
Die Attach
Attachment to a circuit board is made simple through the use of surface mount technology. Mounting pads are
conveniently located on the bottom surface of these devices and are removed from the active junction locations.
These devices are well suited for solder attachment onto hard and soft substrates. The use of 80/20, Au/Sn,
60/40, Sn/Pb or RoHS compliant solders is recommended. Conductive silver epoxy solder may also be used but
could result in an increase in series and thermal resistance.
When soldering these devices to a hard substrate, hot gas die bonding is preferred. We recommend utilizing a
vacuum tip and force of 60 to 100 grams applied to the top surface 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 and reflow the solder by heating the circuit
trace near the mounting pads while applying 60 to 100 grams of force perpendicular to the top surface of the die.
The solder joint must not be made one pad at a time. Doing so could create unequal heat flow and produce
thermal and/or mechanical stresses. It is also not recommended to reflow solder 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 attach is completed.
Recommended temperature and re-flow profiles for 60/40, Sn/Pb and RoHS compliant solders are provided in
Application Note M538 , “Surface Mounting Instructions“.
