Target PCB Recommendations
Total thickness: 1.6mm min.
Plating: Gold or Solder finish
PCB Pad height: Same or higher than solder mask
**** To effectively conduct heat away from the package a
thermal pad is recommended with vias spaced
1.0 to 1.2 mm pitch and a diameter of 0.3 to 0.33 mm.
Ideally 1 via for every 3 leads has been shown to work well.
NOTE: Steel backing plate may be required based on end user's application
