Restrictions on the use of CFCs for cleaning PWBs and present day electronic printed circuit designs incorporating greater
packaging density, fine pitch technology, increased operating frequencies as well as hostile operating environment demand
greater level of surface cleanliness, more thorough assembly testing and process quality control. In response to emerging needs,
ASR Instruments has developed a fully integrated and flexible SIR test system.
This high speed test system has a unique patented capability of continuously monitoring insulation resistance even under bias
condition and display the data in real time. The programming of test and bias voltages (+/- 0 to 500VDC), dwell and test intervals
etc. are programmable by menu driven questions on the data terminal. Once the test procedure is programmed the system will
run the entire test automatically without operator intervention. The unit is very simple to operate and is extremely user friendly.
We provide a computer software to enable standard spreadsheets like Lotus, Excel etc. on PC to analyze the data collected over
long periods and produce custom reports and graphs. We also provide all the cabling, connectors and hardware for mounting the
test coupons in the chamber. We can provide you with a complete turnkey system including test chamber, system installation
and training.
If you need to do SIR testing or electrochemical migration test, this is the best and most advanced integrated equipment available
that can give you most reliable, extremely repeatable and accurate data at a very reasonable cost. ASR Instruments meets the
requirements of Hewlett Packards EL-EN861-00 Electrochemical Migration (ECM) Test.
ASR Instruments is a member of IPC SIR working committee. We have been manufacturing SIR test systems since 1990. Our
customers include Boeing, Bellcore, Motorola, Lucent, AT&T, Celestica, Kester Solder, Alphametals, Enthone Omi, Morton
Electronics, Aim, Northrop Grumman, US Airforce, IME, Litton, Norvartis, Netsteel, etc. We also have customers and service
providers in Canada, Singapore, Taiwan, China, Malaysia and Thailand.
