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.

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.

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 ude af funktion. Undgå udsaettelse for stråling.

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 sets from1 Jan2005 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 theadjusted temperature atthe 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 notexceed ~ 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-recogni zable soldering
temperature profile of the specific BGA (for de­soldering always use thelead-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 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.
