The OSC series of TCXO s and VCTCXO s has
been designed for pick and place and reflow sol-
dering. Units are available on Tape and Reel at
no additional charge when ordering a complete
reel. The reel size is 2000 pcs and is compatible
with EIAJ-1009B standards. The suggested
reflow profile is shown below. The TCXO may be
reflowed two times. Frequency shift as a result of
reflow will be <1.0PPM. Units should not be
adjusted to center frequencies until at least 2
hours after reflow to allow the crystals to stabilize.
The OSC footprint is compatible with many of the
previous generation 6 pin leaded TCXO s. Our
OSE model is the same size as the OSC except it
provides the two additional pads to match pad con-
nections of 6 pin leaded TCXO s and VCTCXO s.
TCXO s are precision subsystems with tolerances
measured to
Non-hermeti-
cally sealed TCXO s should not be subjected to a
wash process that will immerse the TCXO in sol-
vents. No clean is the recommended procedure.
