10、 be sure to use the pb free solder.INDENTIFICATION:Regardless of special logo (not always indicated)one must treat all sets from 1 Jan 2005 onwards, 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/ le

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 cont

12、act 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 ableTo reach at least a solder-temperature of

13、400C,To stabilize the adjusted temperature at the solder-tipTo exchange solder-tips for different applications. Adjust your solder tool so that a temperature around360C 380C is reached and stabilized at the solderjoint. Heating-time of the solder-joint should not exceed 4 sec. Avoid temperatures abo

14、ve 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 allo

15、y 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)ha

16、s to be purchased at external companies. Special information for BGA-ICs: Always use the 12nc-recognizable solderingtemperature profile of the specific BGA (for de-soldering always use the lead-free temperature profile,in case of doubt) Lead free BGA-ICs will be delivered in so-called dry-packaging

17、(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

18、 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. On our website www.atyourservice.ce.Pyou find more information to: BGA-de-/solder
