LEAD FREE PRODUCED SET
This set is manufactured with lead-free
production technology. This is also indicated by
the PHILIPS-lead-free logo you find on the
printed boards.
The set is produced with lead-free solder-alloy as well as
with lead-free sub-parts. It can be considered as lead-free.
Due to this fact some rules have to be respected by the
workshop during a repair:
• Use only lead-free soldering-tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder-paste is required,
please contact the manufacturer of your solder-equipment.
• Use only adequate solder tools applicable for lead-free
soldering-tin.
• Adjust your solder tool so that a temperature around 217°
– 220° is reached at the solder joint.
• Do not mix lead-free soldering-tin with leaded soldering-tin.
This would lead to unreliable solder joints.
• On our website http://www.atyourservice.ce.philips.com
you find more information to
– aspects of lead-free technology
– BGA-de-/soldering, heating-profiles of BGAs used in
Philips-sets, and others.
