bonding. The back surface of these devices is metallized for solder attachment of the chip resistor to a heat sinking substrate.
Note 3: Thermal Resistance - In High Power Applications where the circuit board material
provides high heat sinking benefits (such as IMS, Alumina, or other) the thermal resistance of
the chip resistor is useful to establish the maximum power capability of the chip resistor in the
application. The film temperature is measured at the center of the resistor element and the
solder pad temperature is measured at the soldered interface with the circuit board. Maximum
temperature of the chip resistor (at the center of chip) should not exceed 150°C through the
temperature range of the application.

Solder attachment notes:
During soldering of the Type CD Resistor
the soldering temperature profile must not
cause the pedestal terminals of this device
to exceed 220°C.
Style FC - Flip Chip version resistors
have a bare ceramic back surface. The
recommended solder for flip chip solder
attachment is 62Sn / 36Pb / 2Ag.
Style WB - Wire Bond version resistors
have a metallized back surface for
soldering to a substrate or a heat sink.
The recommended solder is
62Sn / 36Pb / 2Ag.

Packaging information:
Style FC, flip chip resistors, are shipped with the bare
ceramic side up in the pocket, with the solderable pedestals
facing down.
Style WB, wire bondable resistors, are shipped with the
wire bondable pedestals facing up in the pocket.
The illustration shows the orientation of the CD2015 chip
resistors in the tape. The CD2520 chip resistors are rotated 90°
from what is shown in the illustration.
Full reel quantities:
Quantities of less than 250 will be shipped in tape without reel
and without tape leader at the option of Caddock.
Tape dimensions and materials will be consistent with EIA-481-1.
Reels will be marked with a label containing Caddock logo, part
number, resistor value, tolerance, packaging date, and quantity.
