4-bit LVTTL to GTL transceiver

[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, TSSOP, VSO and VSSOP 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]

Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered

pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by

using a hot bar soldering process. The appropriate soldering profile can be provided on request.

[9]

Hot bar soldering or manual soldering is suitable for PMFP packages.
