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.

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.

For proper functionality of the loader this solder joint must be remove after connection loader to the set.
