So best to always use SAC305and the higher temperatures belon

25、g 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-

26、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 400C,To stabilize the adjusted temperature at the solder-tipTo exchange

27、 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 above 400C otherwisewear-out of tips will rise drastically and flux-fluid

28、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 whet

29、her 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-IC

30、s: 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 (sealed pack including a silica gel pack) toprotect the IC against mois

31、ture. 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 lea

32、ded solder-alloy andcomponents, all needed spare-parts will be availabletill the end of the service-period. For repair of suchsets nothing changes.
