Soldering Considerations
Convection heating is recommended for reflow soldering; direct-
infrared heating is not recommended. The plastic ODFN package
does not require a custom reflow soldering profile, and is qualified to
+260°C. A standard reflow soldering profile with a +260°C
maximum is recommended.
Suggested PCB Footprint
It is important that users check the “Surface Mount Assembly
Guidelines for Optical Dual FlatPack No Lead (ODFN) Package”
before starting ODFN product board mounting.

Layout Considerations
The ISL29029 is relatively insensitive to layout. Like other I
devices, it is intended to provide excellent performance even in
significantly noisy environments. There are only a few
considerations that will ensure best performance.
Route the supply and I
noise. A 0.1µF and 1µF power supply decoupling capacitors need to be
placed close to the device.
