Ionic Contamination (Cleanliness) Tester
For Ionic Contamination Testing of Populated and Bare PCB's
Specifically cited in MIL-2000A, the Zero-Ion ionic contamination tester is
one of the industry’s most popular Resistivity of Solvent Extract (ROSE)
testers. IPC-001 and IPC TM650 recognize ROSE testing as an approved
method of determining the cleanliness of circuit assemblies.
Today, in an environment where densely populated surface mount
technology has become commonplace, and where ISO, TQM, Six Sigma,
and other quality standards are commonplace, cleanliness verifications
are frequently required and essential.
The Zero-Ion has been in constant production since the 1980’s.
Thousands of customers rely on the Zero-Ion to determine the final
cleanliness of post-reflow circuit assemblies as well as bare boards. The
Zero-Ion g3 is the newest, most advanced Zero-Ion ever designed.
Aqueous Technologies' Zero Ion ionic contamination tester is equipped
with the following features and benefits:
Process Control
The Zero-Ion g3 is powered by a Windows-based PC for
unerring accuracy. A large 19” (48cm) LCD user interface
provides clear,organized real-time
process
information.
Intuitive tabbed display screens conveniently organize both
stored and real-time process data. Builtin SPC data recording captures all relevant testing data. An
integrated SPC database lookup allows users to search for
desired data sets, including SPC results by date range,
recipe name, board serial number, etc. Cleanliness results
may be stored for later viewing or may be printed onto any
Windows compatible printer. Additionally, the Zero-Ion g3
may be networked for remote viewing of all SPC data.
An optional barcode scanner rovides one-touch entry of a
board’s serial number or other process data.
The PC-based control system automatically calculates
NaCl/square equivalence (per military and IPC
specifications), operates in an automatic or anual mode,
and is equipped with virtually limitless test recipe
capabilities..
Meets Cleanliness Specifications
The Zero-Ion Ionic Contamination Tester meets industrial
cleanliness specifications including MIL-STD-2000A,
MIL-P-28809, IPC-TM-650, and ANSI/J-STD-001B,
IPC-TM650.
Submerged Sprays
The submerged sprays provide excellent agitation of the
test solution while eliminating test inaccuracies caused by
carbon dioxide adsorption associated with other open-air
spray systems. The combination of test-board submersion
and immersion spraying creates an environment whereby
all of the soluble contamination is extracted and measured.
It is this immersion spraying action that gives the Zero Ion
system its superiority in ionic contamination detection.
Dynamic
Measurement Technology
Modern cleanliness testing frequently requires the testing
of assemblies reflowed with no-clean solder paste. Unlike
other less sensitive static-based systems, the Zero-Ion g3
tester utilizes a dynamic measurement technology, the
method of choice for detecting (weak) ion activators
commonly found in no-clean fluxes. With dynamic
measurement technology, the contaminated test solution is
monitored and then filtered to supply de-ionized test
solution back to the test chamber, resulting in greater
solubility / sensitivity. The increased solubility eliminates
the "saturation limit effect", associated with other static
measurement methods.
Cost Effective
The Zero Ion tester is extremely cost effective. Its price is
among the lowest in the industry, yet its performance is
second to none.
Ambient Testing.
Unlike other systems which require heated test solution, the
Zero-Ion performs all tests at ambient temperature,
eliminating the need for heaters and their associated safety
concerns. Ambient temperature testing also reduces
machine startup times and test solution evaporation.
