MicroCel
MicroCel:
The centrifugal energy,
generated when parts are
rotated in a sealed process
chamber, produces results
unattainable through any
other available technology.
High Performance Centrifugal Cleaning System
The MicroCel Centrifugal Cleaning System provides incomparable cleaning of electronic circuit
assemblies, precision parts, medical devices, bumped wafers, and advanced packages, such as ip chips,
MCMs, SIPs, BGAs, CSPs and hybrid circuits. Centrifugal energy, produced when parts are rotated inside
a sealed process chamber, provides unparalleled penetration, solubilization, and contaminant removal
when coupled with appropriate cleaning chemistries. The complete three-step cleaning process achieves
washing, rinsing, and drying results unattainable through any other technology available.
The patented MicroCel system is an industry-rst for cleaning in the electronics and semiconductor
packaging industries. It bears no resemblance to other cleaning systems, but employs concepts,
technologies, and qualities most often found in semiconductor processing equipment.
New Productivity-Enhancing Features
For flexibility and ease-of use, the MicroCel system now offers a new enhanced operator interface. It can
store and retrieve up to 50 recipes and has adjustable programming, configurable alarms, and the option
to manage recipes remotely via an Ethernet link. The new graphical user interface enables flexible recipe
generation and the performance of 20 operational steps. These steps include immersion wash, spin-off,
immersion and spray rinse, dry and cool - in any order - with adjustable parameters of spin RPM, cycle
time, and number of cycles. Additional enhancements to the process chamber include the introduction
of level control monitoring and a pre-mixing feature that recirculates the wash tank to keep chemistries
from separating.
Features and Benefits:
MicroCel
Fixturing
Products cleaned in the MicroCel system are held in place and secured to the head using either universal
adjustable xtures, standard xtures, or custom xtures specic to your product type. Standard xtures are
available for smaller circuit modules, wafers, singulated packages, Auer® boats, magazines, cassettes and JEDEC
trays. All custom xtures are designed by Accel for each customer application, considering part size, weight,
UPH, inertia, operator friendliness, uid dynamics, and long term robustness. Loading of product types into
xtures can occur o-line during the MicroCel unit’s semiautomatic sequence. Fixtures are mounted to the
heads for universal coupling in seconds and are easily interchanged by actuating a single release mechanism.
Performance Features and Benets
Solvent Versatility
With today’s uncertainty about tomorrow’s solvents, the risk in buying a cleaning system is substantial.
Expensive new equipment may quickly become obsolete when a change is made in the choice of cleaning
solutions. MicroCel is the only system currently available that can handle most cleaning solutions, including
H
O, saponified solutions, semi-aqueous solutions, detergents, alcohol-based solvents, and terpenes. With
the MicroCel system, you can meet your needs today and tomorrow.
Incomparable Cleaning
By any measure — ionic, SIR, or visual — cleaning results produced by MicroCel technology far exceed all
others. Ionic contamination of 0.00 micrograms/inch, surface insulation resistance greater than 10 ohms/
inch and no visible residue at 45X magnification upon component removal are typical cleaning results.
Zero-Discharge
The MicroCel zero-discharge system is an automatic, on-board, closed-loop, fully integrated waste water
treatment system. When using solvents that separate from water, the zero-discharge system automatically
removes them from the used rinse water and returns the wash solvent to the wash reservoir for reuse. The
used rinse water is then processed through a four-stage purification process, including microbial control,
5-micron filtration, carbon adsorption, and mixed-bed deionizing resin to restore the rinse water to its original
purity level. No drain or waste water treatment systems are required.
Complete Drying
The MicroCel system uses centrifugal energy and heated flowing air to completely dry complex products in
seconds. No other technology can produce 100% dry, spot-free results as efficiently. With the MicroCel unit,
blowers and bake out ovens are unnecessary.
Compact Size
The MicroCel system delivers more performance per square foot of manufacturing floor space than any other
cleaning technology. All washing, rinsing, drying, and product preparation is performed in 18 square feet.
And with the zero-discharge feature, the complete separation, filtration, and reclamation of all solvent and
rinse water occurs inside the standard cabinet.
