Standard Notes for Servicing
Circuit Board Indications
1. The output pin of the 3 pin Regulator ICs is
indicated as shown.
2. For other ICs, pin 1 and every fifth pin are
indicated as shown.
3. The 1st pin of every male connector is indicated as
shown.
Instructions for Connectors
1. When you connect or disconnect the FFC (Flexible
Foil Connector) cable, be sure to first disconnect
the AC cord.
2. FFC (Flexible Foil Connector) cable should be
inserted parallel into the connector, not at an
angle.
Pb (Lead) Free Solder
When soldering, be sure to use the Pb free solder.
Information about lead-free soldering
Philips CE is producing lead-free sets from 1.1.2005
onwards.
IDENTIFICATION
Regardless of special logo (not always
indicated)
One must treat all sets from
onwards, according to the next rule:
Serial Number gives a 14-digit. Digit 5&6 shows the
YEAR, and digit 7&8 shows the WEEK.
So from
onwards=from 1 Jan 2005 onwards
Important note : In fact also products of year 2004
must be treated in this way as long as you avoid
mixing solder-alloys (leaded/ lead-free). So best to
always use SAC305 and the higher temperatures
belong to this.
Due to lead-free technology some rules have to be
respected by the workshop during a repair:
• Use only lead-free solder alloy Philips SAC305 with
order code 0622 149 00106. If lead-free solder-
paste is required, please contact the manufacturer
of your solder-equipment. In general use of solder-
paste within workshops should be avoided because
paste is not easy to store and to handle.
• Use only adequate solder tools applicable for lead-
free solder alloy. The solder tool must be able
• To reach at least a solder-temperature of 400°C,
• To stabilize the adjusted temperature at the solder-
tip
• To exchange solder-tips for different applications.
• Adjust your solder tool so that a temperature around
360°C - 380°C is reached and stabilized at the
solder joint. Heating-time of the solder-joint should
not exceed ~ 4 sec. Avoid temperatures above
400°C otherwise wear-out of tips will rise drastically
and flux-fluid will be destroyed. To avoid wear-out of
tips switch off un-used equipment, or reduce heat.
• Mix of lead-free solder alloy / parts with leaded
solder alloy / parts is possible but PHILIPS
recommends strongly to avoid mixed solder alloy
types (leaded and lead-free).
If one cannot avoid or does not know whether
product is lead-free, clean carefully the solder-joint
from old solder alloy and re-solder with new solder
alloy (SAC305).
• Use only original spare-parts listed in the Service-
Manuals. Not listed standard-material (commodities)
has to be purchased at external companies.
