REFER TO BACK COVER FOR IMPORTANT SAFETY GUIDELINES
CAUTION: USE A SEPARATE ISOLATION TRANSFORMER FOR THIS UNIT WHEN SERVICING.
ANY PERSON ATTEMPTING TO SERVICE THIS CHASSIS MUST FAMILIARIZE HIMSELF WITH THE CHASSIS
AND BE AWARE OF THE NECESSARY SAFETY PRECAUTIONS TO BE USED WHEN SERVICING ELECTRONIC
EQUIPMENT CONTAINING HIGH VOLTAGES.

Repair tips
0. Warning
1. Servicing of SMDs (Surface Mounted Devices)
All ICs and many other semi-conductors are susceptible to
electrostatic discharges (ESD). Careless handling during repair can
reduce life drastically. When repairing, make sure that you are
connected with the same potential as the mass of the unit via a wrist
wrap with resistance. Keep components and tools also at the same
potential !
1.1 General cautions on handling and storage
- Oxidation on the terminals of SMDs results in poor soldering. Do not
handle SMDs with bare hands.
- Avoid using storage places that are sensitive to oxidation such as
places with sulphur or chlorine gas, direct sunlight, high
temperatures or a high degree of humidity. The capacitance or
resistance value of the SMDs may be affected by this.
- Rough handling of circuit boards containing SMDs may cause
damage to the components as well as the circuit boards. Circuit
boards containing SMDs should never be bent or flexed. Different
circuit board materials expand and contract at different rates when
heated or cooled and the components and/or solder connections
may be damaged due to the stress. Never rub or scrape chip
components as this may cause the value of the component to
change. Similarly, do not slide the circuit board across any
surface.
1.2 Removal of SMDs
- Heat the solder (for 2-3 seconds) at each terminal of the chip. By
means of litz wire and a slight horizontal force, small components
can be removed with the soldering iron. They can also be
removed with a solder sucker (see Fig. 8.1A)
- While holding the SMD with a pair of tweezers, take it off gently
using the soldering iron's heat applied to each terminal (see
Fig. 8.1 B).
- Remove the excess solder on the solder lands by means of litz wire
or a solder sucker (see Fig. 8.1C).
1.3 Caution on removal
- When handling the soldering.iron. use suitable pressure and be
careful.
- When removing the chip, do not use undue force with the pair of
tweezers.
- The soldering iron to be used (approx. 30 W) should preferably be
equipped with a thermal control (soldering temperature: 225 to
250 C).
- The chip, once removed, must never be reused.
1.4 Attachment of SMDs
- Locate the SMD on the solder lands by means of tweezers and
o
solder the component on one side. Ensure that the component is
positioned correctly on the solder lands (see Fig. 8.2A).
- Next complete the soldering of the terminals of the component (see
Fiq. 8.2B).
- When soldering the SMD terminals, do not touch them directly with
the soldering iron. The soldering should be done as quickly as
possible, care must be taken to avoid damage to the terminals of
the SMDs themselves.
- Keep the SMD's body in contact with the printed board when
soldering.
- The soldering iron to be used (approx. 30W)should preferably be
equipped with a thermal control (soldering temperature: 225 to
250 C).
- Soldering should not be done outside the solder land.
- Soldering flux (of rosin) may be used, but should not be acidic.
- After soldering, let the SMD cool down gradually at room
temperature.
- The quantity of solder must be proportional to the size of the solder
land. If the quantity is too great, the SMD might crack or the solder
lands might be torn loose from the printed board (see Fig. 8.3).
