WARNING

ESD
WAARSCHUWING
NL
ll ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.
F
ATTENTION
Tous les IC et beaucoup d’autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution n’est
prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié
au même potentiel que la masse de l’appareil et
enfiler le bracelet serti d’une résistance de
sécurité.
Veiller à ce que les composants ainsi que les
outils que l’on utilise soient également à ce
potentiel.

WARNUNG
Alle ICs und viele andere Halbleiter sind
empfindlich gegenüber elektrostatischen
Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie, dass Sie im Reparaturfall über
ein Pulsarmband mit Widerstand verbunden
sind mit dem gleichen Potential wie die Masse
des Gerätes.
Bauteile und Hilfsmittel auch auf dieses gleiche
Potential halten.
ESD PROTECTION EQUIPMENT
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor electrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie kan
de levensduur drastisch doen verminderen.
Zorg ervoor dat u tijdens reparatie via een
polsband met weerstand verbonden bent met
hetzelfde potentiaal als de massa van het
apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.
I
AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevità potrebbe essere fortemente
ridatta in caso di non osservazione della più
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziale.
GB
Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used.

After servicing and before returning set to customer perform a leakage
current measurement test from all exposed metal parts to earth ground
to assure no shock hazard exist, The leakage current must not
exceed 0.5mA.

Pb(Lead) Free Solder
When soldering , be sure to use the pb free solder.
INDENTIFICATION:
Regardless of special logo (not always indicated)
onemusttreatall sets from1 Jan 2005 onwards,according
next rules:
Important note: In fact also products of year 2004 must
be treated in this way as long as you avoid mixing solderalloys (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 unused 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.
• Special information for BGA-ICs:
– Always use the 12nc-recognizable soldering
temperature profile of the specific BGA (for desoldering always use the lead-free temperature profile,
in case of doubt)
– Lead free BGA-ICs will be delivered in so-called ‘dry-
packaging’ (sealed pack including a silica gel pack) to
protect the IC against moisture. After opening,
1 - 7
dependent of MSL-level seen on indicator-label in the
bag, the BGA-IC possibly still has to be baked dry.
(MSL=Moisture Sensitivity Level). This will be
communicated via AYS-website.
Do not re-use BGAs at all.
• For sets produced before 1.1.2005 (except products
of 2004), containing leaded solder-alloy and
components, all needed spare-parts will be available
till the end of the service-period. For repair of such
sets nothing changes.
• On our website www.atyourservice.ce.Philips.com
you find more information to:
• BGA-de-/soldering (+ baking instructions)
• Heating-profiles of BGAs and other ICs used in
Philips-sets
You will find this and more technical information
within the “magazine”, chapter “workshop news”.
For additional questions please contact your local
repair-helpdesk.
