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.
