2.1 Lead Free Requirements

Pb(Lead) Free Solder

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 solder-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-paste 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 at least a solder-temperature of 400°C,
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 360°C
– 380°C is reached and stabilized at the solder joint. Heating­time 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.

• Mix of lead-free solder alloy / parts with leaded solder alloy /
parts is possible but PHILIPS recommends strongly to avoid
mixed solder alloy types (leaded and lead-free).
If one cannot avoid or does not know whether product is lead­free, 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.
Not listed standard-material (commodities) has to be
purchased at external companies.

• Special information for BGA-ICs:

- always use the 12nc-recognizable soldering temperature
profile of the specific BGA (for de-soldering always use the
lead-free temperature profile, in case of doubt)

- lead free BGA-ICs will be delivered in so-called ‘dry­packaging’ (sealed pack including a silica gel pack) to protect
the IC against moisture. After opening, dependent of MSL­level seen on indicator-label in the bag, the BGA-IC possibly
still has to be baked dry. (MSL=Moisture Sensitivity Level).
This 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 our website www.atyourservice.ce.Philips.com you find
more information to:



BGA-de-/soldering (+ baking instructions)
 Heating-profiles of BGAs and other ICs used in
Philips-sets

You will find this and more technical information within the

“magazine”, chapter “workshop news”.

For additional questions please contact your local repair-helpdesk.

2.2 Service Hints

CAUTION

CHARGED CAPACITORS ON THE SERVO BOARD MAY DAMAGE THE DRIVE
ELECTRONICS WHEN CONNECTING A NEW DRIVE.THAT’S WHY, BESIDES THE SAFETY
MEASURES LIKE

• SWITCH OFF POWER SUPPLY

• ESD PROTECTION
ADDITIONAL ACTIONS MUST BE TAKEN BY THE REPAIR TECHNICIAN.

The following steps have to be done when replacing the defective loader :

1. Dismantling of the loader to access the ESD protection point if necessary.

2. Solder the ESD protection point*.

3. Disconnect flexfoil cable from the defective loader.

4. Put a paper clip on the flexfoil to short-circuit the contacts (fig.1)

5. Replace the defective loader with a new loader.

6. Remove paperclip from the flexfoil and connect it to the new loader.

7. Remove solder joint on the ESD protection point.

ATTENTION: The laser diode 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 point is accessible from bottom of the loader)

*Only applicable for defective loader needed to be sent back to supplier for failure analysis and to support backcharging
evidence.
This is also applicable for all partnership workshops.
