Safety instructions
1.10 Handling the X-ray unit
Some YS series inspection equipment models contain an X-ray unit. Take the following precautions when using
with an X-ray unit.
1. The X-ray output window of the X-ray source is made of very thin beryllium foil.
· Beryllium in the form of dust particles can cause acute toxicity or chronic toxicity, and may induce respiratory
problems if inhaled.
· To ensure safety, the X-ray unit is designed so that the X-ray window cannot be touched. However, should the X-ray
output window be broken for some reason, immediately turn off the power switch and use extreme care not to inhale
the dust particles.
· Chlorine gas can corrode the beryllium window of the X-ray tube, causing permanent damage to the X-ray tube. Do
not use the X-ray unit in environments where chlorine gases are generated. Take special care when handling samples
such as vinyl chloride materials which may generate chlorine gases.
2. Lead is used in the covers of machines equipped with an X-ray unit.
Although lead is sealed within the covers so that the lead portions cannot be directly touched, use caution since lead is
known as heavy metal having harmful effects.
3. A safety key is provided for machines equipped with an X-ray unit.
The safety key must be managed by the supervisor of the machine.
4. Safety education about X-ray
Appropriate measures are taken for YAMAHA's X-ray unit so that the amount of the X-ray leak to the outside of the
equipment is very small. Therefore, when using this equipment in Japan, it is not necessary to set controlled areas defined
in Article 3 of the Ordinance on Prevention of Ionizing Radiation Hazards.
It is not legally obligated to conduct the safety education, but it is recommended to conduct the education by the
customer.
When operating this equipment outside Japan, the safety education is conducted as required according to the relevant
country's laws, regulations, and standards.
TIP
When conducting the safety education in Japan, the contents stated in “Special Education Standard for Radiography
(Ordinance of the Ministry of Health, Labor and Welfare No. 50)” are recommended. However, the safety education
does not necessarily need to be these contents.
c
CAUTION
When disposing of an X-ray unit (X-ray source), dispose of it in compliance with the laws and regulations of the
country where the machine is used. If you have any questions about disposal of the unit, please contact our sales
representatives.
1.11 Handling the laser
In this machine (including optional units), there are portions using the laser, such as a sensor and barcode
reader.
c
CAUTION
The laser to be used by this machine is class 2 (visible light and low output) at a maximum.
Knowledge and information about laser
1. Harmful to human body
Never look at the laser directly even when it is weak. In particular, if the laser is irradiated to an eye for a long time,
this may cause serious injury.
2. Reflection of laser
The laser is reflected by a glass or metal surface. Pay special attention to the reflected laser light during maintenance
work.
To prevent accidents caused by laser
1. Do not align your eye with the laser height so that you do not look at the laser directly.
2. Wear safety goggles during work, when necessary.
3. Shield the laser during work, when necessary.

1.12 Handling grease and oil
Grease or oil is used for the operating axes of this machine. When performing the lubrication work, strictly
observe the cautions shown below.
Cautions on handling grease and oil
1. If grease or oil enters your eye or sticks to your skin, this may cause inflammation. Be sure to wear safety goggles and
protective gloves during work. Additionally, if you swallow grease or oil by mistake, this may cause vomiting or
diarrhea.
2. If grease other than that specified is used, this may cause damage to the machine.
3. If grease with different characteristics is mixed with proper grease, this may cause the machine performance to lower.
4. Be sure to cap tightly after use to prevent entry of dust or water content. When storing the grease or oil, avoid the
direct sunlight, keep it away from a fire, and store it in a dark place.
n
NOTE
When the safety data sheet (MSDS/SDS) about the grease or oil that is used for the maintenance wok is needed,
contact our sales representatives.
1.13 Handling batteries
Batteries are used for some motors of this machine and the optional uninterruptible power supply (UPS).
Cautions on handling batteries
1. Do not disassemble the battery or touch its inside. Otherwise, electrical shock may result.
2. Do not over-heat or apply a strong impact to the battery. Otherwise, fluid leakage, explosion, or heat generation, etc.
may result. Never use the battery, to which a strong impact has been applied, such as dropping to the floor since its
battery fluid may leak.
3. Only engineers who have the experience and knowledge about electrical work are allowed to replace the battery.
4. The battery may discharge naturally. When purchasing a spare battery, do not store it for a long period and prepare it
one to two months before the scheduled replacement work. Additionally, when storing the battery, avoid a place where
the temperature increases and be sure to store it at room temperature.
n
NOTE
When the safety data sheet (MSDS/SDS) about the battery is needed, contact our sales representatives.
c
CAUTION
For details about how to handle the UPS, see the user's manual prepared by the manufacturer that is supplied with the
UPS.
c
CAUTION
When disposing of a battery, dispose of it in compliance with the laws and regulations of the country where the
machine is used. If you have any questions about disposal of the battery, please contact our sales representatives.
1.14 Handling heavy objects
This machine (including optional units) may require the operator to handle heavy objects during work. (For
example, magazine or cassette replacement) If you hold up a heavy object in an unnatural posture, this may
cause damage to your back. Additionally, if you fall a heavy object to your feet, this may cause serious
personal injury. Or, falling a heavy object may cause damage to the magazines or internal tray components.
Cautions on handling heavy objects
1. Be careful not to take an unnatural posture during work. In particular, be aware that you may take an unnatural posture
easily when holding up a heavy object from a low place. It is recommended to hold up a heavy object by bending and
stretching your knee instead of bending your waist or prepare a cart with an appropriate height when necessary.
2. When a handle is provided, such as magazine and cassette, hold the handle securely and perform the work.
3. To prevent personal injury caused by heavy object dropping, be sure to wear safety shoes.
c
CAUTION
When heavy object handling standards are defined at the customer's factory, be sure to follow the standards during
work.

1.15 Components and materials to be used
This machine uses not only the surface-mounted components but also the various types of materials such as
trays, wafer components, dicing tapes and so on. In selecting these components and materials, observe the
following.
1. Do not use the flammable (explosive) material.
2. Do not use the material whose function is impaired by heating.
For example, some flip tip bonders are equipped with a heater inside the unit (e.g. YSB55w : The dicing tape is heated
to approx. 60 degrees.) Do not use the flammable materials or the materials impaired by heat.
3. Do not use the materials that reacts chemically with solders, flux, adhesive and solvents used for cleaning them.
4. Select components and materials that meet the specifications of the machine.
n
NOTE
Check the detailed specifications of the components and materials with the suppliers beforehand. If you have any
questions about the specifications of the machine, please contact our sales representatives.
