Älä katso säteeseen!GB WARNINGAll ICs and many other semi-conductors aresusceptible to electrostatic discharges (ESD).Careless handling during repair can reduce lifedrastically.When repairing, make sure that you areconnected with the same potential as the massof the set via a wrist wrap with resistance.Keep components and tools also at thispotential.F ATTENTIONTous les IC et beaucoup dautressemi-conducteurs sont sensibles auxdécharges statiques (ESD).Leur longévité pourrait être considérablementécourtée par le fait quaucune précaution nestprise à leur manipulation.Lors de réparations, sassurer de bien être reliéau même potentiel que la masse de lappareil etenfiler le bracelet serti dune résistance desécurité.Veiller à ce que les composants ainsi que lesoutils que lon utilise soient également à cepotentiel.ESDD WARNUNGAlle ICs und viele andere Halbleiter sindempfindlich gegenüber elektrostatischenEntladungen (ESD).Unsorgfältige Behandlung im Reparaturfall kandie Lebensdauer drastisch reduzieren.Veranlassen Sie, dass Sie im Reparaturfall überein Pulsarmband mit Widerstand verbundensind mit dem gleichen Potential wie die Massedes Gerätes.Bauteile und Hilfsmittel auch auf dieses gleichePotential halten.DK Advarse !Usynlig laserstråling ved åbning når sikkerhedsafbrydere erude af funktion.

So best to always use SAC305and the higher temperatures belong to this.Due to lead-free technology some rules have to berespected by the workshop during a repair: Use only lead-free solder alloy Philips SAC305 withorder code 0622 149 00106. If lead-free solder-pasteis required, please contact the manufacturer of yoursolder-equipment. In general use of solder-pastewithin workshops should be avoided because paste isnot 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 400C, To stabilize the adjusted temperature at the solder-tip To exchange solder-tips for different applications. Adjust your solder tool so that a temperature around360C 380C is reached and stabilized at the solderjoint.Heating-timeofthesolder-jointshould notexceed 4 sec. Avoid temperatures above 400C otherwisewear-out of tips will rise drastically and flux-fluid willbe destroyed. To avoid wear-out of tips switch off un-used equipment, or reduce heat. Mix of lead-free solder alloy / parts with leaded solderalloy / parts is possible but PHILIPS recommendsstrongly to avoid mixed solder alloy types (leaded andlead-free).If one cannot avoid or does not know whether productis lead-free, clean carefully the solder-joint from oldsolder 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 solderingtemperature profile of the specific BGA (for de-solderingalwaysuse 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) toprotect the IC against moisture. After opening,dependent of MSL-level seen on indicator-label in thebag, the BGA-IC possibly still has to be baked dry.(MSL=Moisture Sensitivity Level). This will becommunicated via AYS-website.Do not re-use BGAs at all. For sets produced before 1.1.2005 (except productsof 2004), containing leaded solder-alloy andcomponents, all needed spare-parts will be availabletill the end of the service-period. For repair of suchsets nothing changes.
