Sobest to always use SAC305 and the higher temperatures

24、 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-paste is required, please contact the manufacturer of your solder-equipment. In general use

25、 of solder-paste withinworkshopsshouldbeavoidedbecausepaste 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

26、 exchange solder-tips for different applications. Adjust 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-

27、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 PHILIPS recommends strongly to avoidmixed solderalloy types (leadedand lead-free). Ifonecannot avoidordoes not know

28、whetherproduct 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- Manuals.
