Glass Lid Specifications
Monochrome Sensor
A D263 glass is used as protection glass lid on top of the IBIS4-6600 monochrome sensors. The refraction index of the D263 glass
lid is 1.52. Figure 30 shows the transmission characteristics of the D263 glass.

Handling and Soldering Conditions
Special care must be taken when soldering image sensors with
color filter arrays (RGB color filters), onto a circuit board,
because color filters are sensitive to high temperatures.
Prolonged heating at elevated temperatures may result in
deterioration of the performance of the sensor. The following
recommendations ensure that sensor performance is not
compromised during end-users assembly processes.
Board Assembly
Device placement onto boards must be done in accordance with
strict ESD controls for Class 0, JESD22 Human Body Model, and
Class A, JESD22 Machine Model devices. Assembly operators
must always wear all designated and approved grounding
equipment. Grounded wrist straps at ESD protected
workstations are recommended, including the use of ionized
blowers. All tools must be ESD protected.
Manual Soldering
When a soldering iron is used, the following conditions must be
observed:
■ Use a soldering iron with temperature control at the tip. The
soldering iron tip temperature must not exceed 350°C.
■ The soldering period for each pin must be less than 5 seconds.
Reflow Soldering
Figure 31 on page 33 shows the maximum recommended
thermal profile for a reflow soldering system. If the
temperature/time profile exceeds these recommendations,
damage to the image sensor may occur. See Figure 31 on page
33 for more details.
Precautions and Cleaning
Avoid spilling solder flux on the cover glass, because bare glass
and particularly glass with antireflection filters may be adversely
affected by the flux. Avoid mechanical or particulate damage to
the cover glass.
It is recommended that isopropyl alcohol (IPA) be used as a
solvent for cleaning the image sensor glass lid. When using other
solvents, it must be confirmed beforehand whether the solvent
can dissolve the package and/or the glass lid.
