Philips Semiconductors

Preliminary specification

YUV picture improvement processor based

on histogram modification

TDA9170

SOLDERING

Plastic dual in-line packages

The maximum permissible temperature of the solder is

260

°C; this temperature must not be in contact with the

joint for more than 5 s. The total contact time of successive

solder waves must not exceed 5 s.

The device may be mounted up to the seating plane, but

the temperature of the plastic body must not exceed the

specified storage maximum.

If the printed-circuit board has been pre-heated, forced

cooling may be necessary immediately after soldering to

keep the temperature within the permissible limit.

Apply a low voltage soldering iron below the seating plane

(or not more than 2 mm above it). If its temperature is

below 300

°C, it must not be in contact for more than 10 s;

if between 300 and 400

°C, for not more than 5 s.
