21、r When soldering , be sure to use the pb free solder. INDENTIFICATION: Regardless of special logo (not always indicated) one must treat all sets from 1 Jan 2005onwards, according next rules: Important note: In fact also products of year 2004 must be treated in this way as long as you avoid mixing so

22、lder- alloys (leaded/ lead-free). So best to always use SAC305 and the higher temperatures belong to this. Due to lead-free technology some rules have to be respected by the workshop during a repair: Use only lead-free solder alloy Philips SAC305 with order code 0622 149 00106. If lead-free solder-p

23、aste is required, please contact the manufacturer of your solder-equipment. In general use of solder-paste within workshops should be avoided because paste is not 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

24、 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 around 360?C 380?C is reached and stabilized at the solder joint. Heating-time of the solder-joint shoul

25、d not exceed 4 sec. Avoid temperatures above 400?C otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed. To avoid wear-out of tips switch off un- used equipment, or reduce heat. Mix of lead-free solder alloy / parts with leaded solder alloy / parts is possible but PHILIP

26、S recommends strongly to avoid mixed solder alloy types (leaded and lead-free). If one cannot avoid or does not know whether product is lead-free, clean carefully the solder-joint from old solder alloy and re-solder with new solder alloy (SAC305). Use only original spare-parts listed in the Service-

27、 Manuals. Not listed standard-material (commodities) has to be purchased at external companies. Special information for BGA-ICs: Always use the 12nc-recognizable soldering temperature profile of the specific BGA (for de- soldering always use the lead-free temperature profile, in case of doubt) Lead

28、free BGA-ICs will be delivered in so-called dry- packaging (sealed pack including a silica gel pack) to protect the IC against moisture. After opening, dependent of MSL-level seen on indicator-label in the bag, the BGA-IC possibly still has to be baked dry. (MSL=Moisture Sensitivity Level). This wil

29、l be communicated via AYS-website. Do not re-use BGAs at all. For sets produced before 1.1.2005 (except products of 2004), containing leaded solder-alloy and components, all needed spare-parts will be available till the end of the service-period. For repair of such sets nothing changes. On our websi
