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
Layout Considerations
The ISL29029 is relatively insensitive to layout. Like other I 2 C
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 2 C traces as far as possible from all sources of
noise. A 0.1μF and 1μF power supply decoupling capacitors need to be
placed close to the device.
Guidelines for Optical Dual FlatPack No Lead (ODFN) Package”
before starting ODFN product board mounting.
