24、r 2004 mustbe treated in this way as long as you avoid mixing solder-alloys (leaded/ lead-free). 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

25、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-fr

26、ee solder alloy. The solder tool must be able To reach at least a solder-temperature of 400?C, To stabilize the adjusted temperature 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

27、solderjoint. Heating-time of the solder-joint should not exceed 4 sec. Avoid temperatures above 400?C 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 le

28、aded 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 or

Special information for BGA-ICs: Always use the 12nc-recognizable solderingtemperature profile of the specific BGA (for de-soldering always use the lead-free tempera

30、ture 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 moisture. After opening,dependent of MSL-level seen on indicator-label in thebag, the BGA-IC possibly still has to be baked dry.(MSL=Moistu
