11、der.INDENTIFICATION:Regardless of special logo (not always indicated)onemusttreatallsetsfrom1 Jan2005onwards,accordingnext rules:Important note: In fact also products of year 2004 mustbe treated in this way as long as you avoid mixing solder-alloys (leaded/ lead-free). So best to always use SAC305an

12、d 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-equip

13、ment. 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 400?C, To stabilize the adjusted temper

14、ature at the solder-tip To exchange solder-tips for different applications. Adjust your solder tool so that a temperature around360?C 380?C is reached and stabilized at the solderjoint.Heating-timeofthesolder-jointshould notexceed 4 sec. Avoid temperatures above 400?C otherwisewear-out of tips will

15、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 ca

16、nnot 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

17、. 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) t

18、oprotect 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 prod

19、uctsof 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.
