always use SAC305 and the higher temperatures

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

• To stabilize the adjusted temperature at the solder-

• To exchange solder-tips for different applications.
360°C - 380°C is reached and stabilized at the
solder joint. Heating-time of the solder-joint should
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.
