4、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 2005 onwards, according next rules: Important note: In fact also products of year 2004 must be treated in this way as long as you avoid mixing sol

5、der-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-pas

6、te 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 o To reach

7、at least a solder-temperature of 400C, o To stabilize the adjusted temperature at the solder-tip o To exchange solder-tips for different applications. Adjust your solder tool so that a temperature around 360C 380C is reached and stabilized at the solder joint. Heating- time of the solder-joint shoul

8、d not exceed 4 sec. Avoid temperatures above 400C otherwise wear-out of tips will rise drastically and fl ux-fl uid 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

9、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

10、-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 profi le of the specifi c BGA (for de-soldering always use the lead-free temperature profi le, in case of doubt) -

11、 lead 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). T

12、his will 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 ou

Remove paperclip from the fl exfoil and connect it to the new loader. 7. Remove solder joint on the ESD protection point. ATTENTION: The laser dio

17、de of this loader is protected against ESD by a solder joint which shortcircuits the laserdiode to ground. For proper functionality of the loader this solder joint must be remove after connection loader to the set. Type 1 Type 2 (ESD protection point is accessible from top of loader) (ESD protection
