SAFETY AND REGULATORY INFORMATION
WARNING
•TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE SYSTEM TO MOISTURE.
•TO PREVENT FIRE OR SHOCK HAZARD, DO NOT USE FLAMMABLE SOLVENTS NEAR
OR ON THE SYSTEM WHILE CONNECTED TO A POWER SOURCE.
•TO PREVENT POSSIBILITY OF INJURY OR DAMAGE TO THE SYSTEM, DO NOT
OPERATE WITH ANY COVERS OR PANELS REMOVED.
•CHANGES OR MODIFICATIONS MADE TO THIS PRODUCT WITHOUT EXPRESS
APPROVAL FROM APR COULD VOID THE USERS AUTHORITY TO OPERATE THE
EQUIPMENT.
•Read and understand the entire Operator’s Manual before installation or operation of the
Scarab Site Cleaning System. Heed all warnings on the system and in the operating
instructions.
•The Scarab Site Cleaning System is only for the removal of residual solder and/or reworkable
glue from printed circuit boards or components by properly trained personnel. If you are not
familiar with the proper and safe operation of the unit, do not operate it until properly trained.
•Operate the unit from the type of power source indicated on the serial number label.
•Use only the supplied power cord. Avoid damage to the power cord. If damage should occur,
replace it with the approved APR replacement power cord.
•This CAUTION symbol on the equipment refers the user to the user guide for additional
information. This symbol appears next to the relevant information in the manual.
•This HOT symbol on the equipment warns the user of a hot surface and potential injury if
touched. This symbol appears next to the relevant information in the manual.
•This HEAVY LIFTING symbol on the packaging warns the user to team lift the Scarab Site
Cleaning System during removal from packaging and installation on the workbench. This
symbol appears next to the relevant information in the manual.
•This PINCH POINT symbol on the equipment warns the user of a potential injury. This symbol
appears next to the relevant information in the manual.
•This LASER symbol on the equipment warns the user of possible exposure to laser radiation.
This symbol appears next to the relevant information in the manual.

When operating this equipment, please exercise caution. If this unit is used in, a manner,
which it is not intended for, serious personal injury, may occur. Please read this user guide
thoroughly prior to use.
The main power cord is a means for disconnecting the equipment from an operating energy
source. Position the equipment in a way that impedes the disconnection of the main power
cord in case of an emergency.
Mandatory use of a grounding strap is required when operating the equipment.
•Laser Safety
•Do not stare into the beam or view directly with optical instruments.
•Laser Height Sensor Module
oThe Laser Height Sensor incorporates a Class 2 laser. Because of its brightness, Class
2 laser light will be too dazzling to stare into for extended periods. Momentary viewing is
not considered hazardous since the upper radiant power limit on this type of device is
less than the MPE (Maximum Permissible Exposure) for momentary exposure of 0.25
second or less. Intentional extended viewing, however, is considered hazardous.
•Crosshair Alignment Laser Module
oA Class 3R laser is considered safe if handled carefully, with restricted beam viewing.
With a class 3R laser, the MPE (Maximum Permissible Exposure) can be exceeded, but
with a low risk of injury. Visible continuous lasers in Class 3R are limited to 5mW.
Other Safety Tips
•Unplug the unit before cleaning. Clean the exterior of the system with a damp cloth. Do not use
solvent-based cleaners.
•Slots and openings in the system are provided for ventilation and to ensure reliable operation
and protection from overheating. The openings should never be blocked or covered.
•Do not overload power outlets and extension cords. This can result in fire or electric shock.
•Unit to comply with CE, UL, & CSA standards.

INTRODUCTION AND GENERAL OVERVIEW
The cost and complexity of today’s electronic assemblies are forcing manufacturers to reexamine the tools and
techniques in operation today. Contactless cleaning of component pads prior to component replacement is a
growing need in the industry. The Scarab Site Cleaning System, APR-2000-SCS, ensures accurate and
repeatable cleaning of the component pad in one user-friendly system. The Scarab Site Cleaning System
redefines performance and addresses the technical demands presented by component manufacturers today.
The trend in the industry is to move away from manual methods of cleaning component pads. The risks to
the PCBA are inconsistent solder removal resulting in poor adhesion, solder resist damage resulting in
opens or shorts, and thermal damage to the PCBA. In an effort to address the costs and risks associated
with the manual process, the industry is looking towards a contactless cleaning as a solution.
The Scarab Site Cleaning System addresses the industry needs with an automated system capable of
cleaning components pads without contact. The motorized design allows the system to clean without
contact component pads up to 50mm x 50mm within a 101mm x 101 mm area. The system can accurately
and repeatedly clean pads with pitches of 0.2mm to 2.0mm. The open-ended board holder fits a wide
variety of large, small and odd-shaped boards while allowing positioning over the patented dual subzone
preheater.
Source temperatures and time intervals can be modified “On-the-Fly", eliminating the need to wait for the
current profile to terminate before modifications can be made with one exception. While in the cleaning
zone, the system automatically calculates the time needed to remove solder and glue and adjusts the time
according to user defined inputs. Precise solder joint temperatures are measured and displayed on a real
time graphical display, thus providing the necessary data to accurately and easily establish the optimum
reflow profile for each particular application within minutes.
The Scarab Site Cleaning System joins the Scorpion Rework System as a solution to the challenges faced
by manufacturers in today’s rework environment.
