These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no 
account be processed through more than one soldering cycle or subjected to infrared reflow soldering with 
peak temperature exceeding 217
°
±
10
°
C measured in the atmosphere of the reflow oven. The package 
body peak temperature must be kept as low as possible.
[4]
These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the 
solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink 
on the top side, the solder might be deposited on the heatsink surface.
[5]
If wave soldering is considered, then the package must be placed at a 45
°
 angle to the solder wave 
direction. The package footprint must incorporate solder thieves downstream and at the side corners.
[6]
Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is 
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
[7]
Wave soldering is suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; 
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
[8]
Hot bar or manual soldering is suitable for PMFP packages.
