Disposal of Laser Vacuum Filters

The laser 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 fil-

ters 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. Analysis of filter contents obtained after marking a representative

variety of devices has revealed a sufficient level of potentially hazardous

material, such as antimony and other heavy metals, to require that you han-

dle and dispose of the filters with other hazardous waste within the facility.

Dispose of the filters in accordance with the facility’s hazardous waste pol-

icy and in a manner that meets all applicable government (local, state, and

federal—or equivalent) regulations.

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

• Threshold Limit Values (TLVs) published by the American Conference

of Environmental Industrial Hygienists (ACEIH).

Laser Vacuum Filter Replacement Intervals

Replace the filters in the fume extractor according to information in the

“Interval Table” on page 5-2. If the filters are not replaced as required, the

laser vacuum system will not be able to prevent fumes and marking by-prod-

ucts from escaping into the work environment.

WARNING: Do not clean the laser vacuum filters by blowing with

compressed air, shaking, or using any method that allows the par-

ticulate trapped by the filters to be released into the work environ-

ment. Dispose of the filters as directed in your fume extractor

manual.

WARNING: Failure to replace the laser vacuum filters at the

required intervals could create a hazardous operating environ-

ment.

Determining Filter Contents

The company contracted to dispose of the facility’s hazardous waste may be

required to perform a profile of the filter contents to determine the specific

composition of the particulate matter. The manufacturer of the semiconduc-

tor devices being marked may be able to provide a profile sheet describing

the composition of their packaging material.

Introduction

1—22 PS288 Owner’s Manual

Standard plastic device packages typically contain antimony hydroxide as a

fire retardant, the source of the antimony in the vacuum filters. Other hazard-

ous materials may also be present depending upon the type of device pack-

ages 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 necessary

information to label the bags containing the filters and will complete the

paperwork required for transportation and disposal in a manner that meets

applicable government (local, state, and federal—or equivalent) hazardous

waste regulations.

Filter Handling and Storage

The procedure for replacing the laser vacuum filters is described in the fume

extractor manual. Following the precautions listed below will help ensure a

safe work area for all personnel using the PS288.

Ensure that protective gloves (disposable latex or vinyl) are worn during the

removal of the contaminated filters. Handle the contaminated filters in a

manner that minimizes the release of the particulate on the filters.

Dispose of the contaminated filters in a tightly sealed plastic bag (such as a

bag with a reusable locking seal). When all filters have been carefully placed

in the bag, pull off the disposable gloves (inside out), place them in the bag,

and seal the bag.

If it is determined that the by-products of laser marking contain potentially

hazardous materials, a hazardous waste label that meets government require-

ments (local, state, and federal—or equivalent) needs to be affixed to this

bag or other hazardous waste container.

WARNING: Numerous government regulations apply to the stor-

age of hazardous waste. Ensure that contaminated filters are

properly labeled and stored in your hazardous waste storage area.

Also, make sure that they are not stored on your site longer than

government regulations allow (the typical limit is 90 days). Check

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

tions for hazardous waste storage requirements.

Ventilation

The PS288, its optional systems, and its label or laser marking system con-

tain mechanical components and associated electrical systems that generate

heat and extremely low levels of particulate matter.
