Laser Safety

The laser marking system, located in the Option Bay attached to the

PS Machine, has been designed in accordance with the following

safety guidelines:

• Operates as a Class 1 laser (CDRH classification).

• Fume extractor traps marking fumes and other by-products of

the laser marking operation.

• System designed to comply with OSHA guarding standards.

• Integrated safety interlocks prevent the laser from firing while

any interlock is activated.

• Refer to and follow laser and safety precautions in ANSI

X136.1-1993, American National Standard for the Safe Use of

Lasers. Procedures listed under the Standard include: appoint-

ment of a Laser Safety Officer, operation of the product in an

area of limited access by trained personnel, servicing of the

equipment only by trained and authorized personnel, and post-

ing of signs warning of potential hazards.

WARNING: Blindness hazard! When servicing, always wear eye

protection when the laser access doors are open. Direct or diffuse

laser radiation can damage eyes. Goggles must block 10.57 to

10.63

m laser radiation. Goggles protect against scattered

energy but not against direct viewing of the laser beam or reflec-

tions from metallic surfaces.

WARNING: Serious burn hazard! Laser radiation, whether direct

or diffuse, can cause serious burns. When servicing, keep hands

and other parts of the body out of the path of the laser beam.

WARNING: Toxic fume hazard! Laser marking generates vapors,

fumes, and particles that may be noxious, toxic, or even fatal. Fol-

low maintenance procedures on the fume extractor. Use proper

ventilation.

Laser Specifications

Specifications for laser Model 48-1(S) installed in the Option Bay:

Laser Safety Interlocks

The Option Bay has five safety interlocks that prevent the laser from

firing when any cabinet panel on the Option Bay is removed. To

physically enable the laser, all panels must be closed. A laser safety

interlock is shown in Figure 1-13.

Figure 1-13: Laser safety interlock is visible when an access panel is

removed.

WARNING: Safety hazard—Never leave the PS Machine unat-

tended with a safety shield removed.

Serious burn hazard—Direct or diffuse laser radiation can cause

serious burns.

Blindness hazard

—Direct or diffuse laser radiation can damage

eyes.

Disposal of Laser Vacuum Filters

The laser marking system uses a vacuum to remove the smoke and

other by-products of the laser marking process. The smoke fumes

pass through a series of filters designed to remove airborne particles

from the operating environment. Material Safety Data Sheets (MSDS)

for materials being processed should be thoroughly evaluated and

the adequacy of provisions for fume extraction, filtering, and venting

should be carefully considered.

The exact composition of the materials trapped by the filters depends

upon the materials used by the semiconductor manufacturer to create

the device package. Dispose of the filters in accordance with the

facility’s hazardous waste policy and in a manner that meets all appli-

cable government (local, state, and federal—or equivalent) regula-

tions.

Review the following references for further information regarding

exposure criteria:

• ANSI Z136.1-1993, Standards for the Safe Use of Lasers, section 7.3.

• U.S. Government’s Code of Federal Registers: 29 CFR 1910,

subpart Z.

• Threshold Limit Values (TLVs) published by the American Confer-

ence of Environmental Industrial Hygienists (ACEIH).

Determining Hazardous Contents

The company contracted to dispose of your facility’s hazardous waste

may be required to perform a profile of the filter contents to deter-

mine the specific composition of the particulate matter. The manufac-

turer of the semiconductor devices being marked may be able to

provide a profile sheet describing the composition of their packaging

material.

Standard plastic device packages typically contain antimony hydroxide

as a fire retardant, the source of the antimony in the vacuum filters.

Other hazardous materials may also be present depending upon the

type of device packages that are laser marked.

After the initial profile is performed and on record with the company

that disposes of the facility’s hazardous waste, additional testing of

contaminated filters should not be needed unless the contents of the

device packages or type of device packages being marked changes

significantly.

The licensed hazardous waste disposal company can provide the nec-

essary information to label the bags containing the filters and paper-

Analysis of filter con-

tents obtained following

marking a representa-

tive variety of devices

has revealed a sufficient

level of hazardous

materials, such as anti-

mony and other heavy

metals, to require that

the filter be treated as

hazardous waste.
