Sobest to always use SAC305 and the higher temperatures belong to this. Due to lead-free technology some r
24、ules 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-paste is required, please contact the manufacturer of your solder-equipment. In general use of solder-paste withinworkshopsshouldbeavoidedbeca
25、usepaste 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 at least a solder-temperature of 400?C, To stabilize theadjustedtemperature atthesolder- tip To exchange solder-tips for different applications. A
26、djust your solder tool so that a temperature around 360?C 380?C is reachedandstabilized at thesolder joint.Heating-timeofthesolder-jointshould notexceed 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
27、switch off un- used equipment, or reduce heat. Mix of lead-free solder alloy / parts with leaded solder alloy / parts is possible but PHILIPS recommends strongly to avoidmixed solderalloy types (leadedand lead-free). Ifonecannot avoidordoes not knowwhetherproduct is lead-free, clean carefully the so

Not listed standard-material (commodities) has to be purchased at external companies. Special information for BGA-ICs: Always use the 12nc-recognizable solderi
29、ng temperature profile of the specific BGA (for de- solderingalwaysuse thelead-free temperatureprofile, in case of doubt) Lead free BGA-ICs will be delivered in so-called dry- packaging(sealedpack including a silica gelpack) to protect the IC against moisture.
