HANDLING CHIP COMPONENTS

NL

WAARSCHUWING

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.

Safety components are marked by the symbol

!

.

NL

Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in
zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,
identiek aan de gespecificeerde, worden toegepast.

De Veiligheidsonderdelen zijn aangeduid met het symbol

Les normes de sécurité exigent que l’appareil soit remis à l’état
d’origine et que soient utiliséés les piéces de rechange identiques
à celles spécifiées.

Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu
beachten. Der Original zustand des Geräts darf nicht verändert werden;

Le norme di sicurezza esigono che l’apparecchio venga rimesso
nelle condizioni originali e che siano utilizzati i pezzi di ricambio
identici a quelli specificati.

GB

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.

Avoid direct exposure to beam.

Osynlig laserstrålning när apparaten är öppnad och spärren

WARNING

A

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.

D

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.

DK Advarse !

Usynlig laserstråling ved åbning når sikkerhedsafbrydere er

Pb(Lead) Free Solder

When soldering , be sure to use the pb free solder.

INDENTIFICATION:

Regardless of special logo (not always indicated)

onemust treat all setsfrom1 Jan 2005onwards, 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 adjustedtemperature at thesolder-

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 thesolder-jointshould 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:
– Al ways use the 12nc-recognizable soldering

temperature profile of the specific BGA (for de­soldering always use the lead-free temperatureprofile,
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,

dependent of MSL-level seen onindicator-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.
