UL-Certified Fume Hoods from HEMCO
Independence, MO — HEMCO’s new series of UniFlow AireStream fume hoods are constructed entirely of chemical-resistant, flame-retardant, non-metallic composite resin materi- als. They are built without screws, bolts, rivets, or any metallic hard- ware. The fume chamber is molded, one piece, and seamless with its cor- ners coved for easy cleaning and light reflectivity.
This series of fume hoods is UL 1805-certified and comes in 48, 60, 72, and 96 in. (1.2, 1.5, 1.8, and 2.4m) widths. The hoods are available in either constant air volume or restricted bypass models.
The AireStream fume hood maximizes user safety and energy savings. This hood is equipped with a 36 in. (0.9m) extended view height, exclusive vector-slotted rear VaraFlow baffle system, an aerody- namic sash lift with perforated air- sweep feature, and a molded-in, belled outlet collar for reduced air- flow resistance.
The lighting is a vapor-proof LED strip fixture with a central switch, prewired to a single-point, 115V, 60 Hz, junction box. The hood is shipped completely assembled and can include a wide selection of acces- sories that can be factory installed to

and inspection machines that simulate the physical test line. These include pick-and-place, AOI and AXI machines, boundary scan test, and fly- ing probe, in-circuit and functional testers. Each model can be tuned to reflect the test and measurement capa- bilities of each individual target tester. Machine data can then be exported that is aligned with the simulated test line. This is in a native format used by assembly and test machines. The outputs include assembly and test programs or input lists and test models, as well as test fixture files. Optimizing a flying probe tester with other complemen- tary test strategies, such as bound- ary scan, not only ensures optimum test coverage, but significantly reduces test time.
tomer. High escape rates also have a direct impact on the “no fault found” bone pile.
The completed, post-debug test program should reflect the estimated coverage requirements defined by the OEM. Outsourced test programs can be measured and compared with early estimations to verify that the original requirements were met. ASTER’s EMS 4.0 workflow is designed to provide faster time-to- market, cost reduction and quality improvements. The company’s soft- ware suite includes TestWay and QUAD. By creating a test strategy hand-in-hand with developing a new product, costly mistakes can be avoided, test coverage can be finely- tuned, and ultimately, higher-quality products delivered.

occurring during production. Design to Test
Typically, a good test strategy that provides an overall high level of coverage is a combination of different test equipment available within the test line. Each test step has the ability to catch a subset of the defects. By identifying the escape rate, it is possi- ble to fill the gaps in the overall test coverage. In order to create a lean test strategy, overlapping tests should be eliminated from the process. Test coverage estimation can be calculated using virtual models for test

Closed-Loop Test
The Industry 4.0 philosophy focuses on providing a closed loop, in order to easily identify problems and fix them. Disparities between expect- ed test coverage and achieved test coverage can occur when test devel- opment and PCB manufacturing is outsourced.
It is critical that the OEM have completely transparent suppliers. Otherwise, there is a good chance that inferior products could be manufac- tured and shipped to the end cus-
Flying probe test program optimization. To Be Precise.
There is also a case for in-circuit test (ICT), where test point placement is optimized for maximum test cover- age or for fixture cost reduction. Carefully designing for test can result in cost savings, as well as saving time in test generation and debug. This can
