Water Leak Testing of Japanese Tiled Roofs under Vibration and Scattering
IERI Procedia, 2020Co-Authors: Satoru OkamotoAbstract:Abstract This paper describes a water Leak Test of roof tiles. The 100 roof tiles were set up on 10 lines and 10 rows on the pitched roof in the downstream of the flow from the wind tunnel. The flow velocity was increased gradually from the low velocity to the high velocity, and the effects of the wind on the roof tiles were investigated by the water Leak Test. The situation of the water Leak Test was filmed by video camera. Two accelerometers were simultaneously used. The roof tiles which showed significant vibration at any velocity were found in a series of experiments and the accelerometers were attached to the two neighboring roof tiles on the model roof. The water Leak phenomena in the experiment by using the artificial rainfall apparatus are discussed in this paper. Some mechanisms with relatively large amplitudes at low-frequency vibrations, which caused water Leak phenomena were made clear.

Review of Test methods used for the measurement of hermeticity in packages containing small cavities
IEEE Transactions on Components Packaging and Manufacturing Technology, 2012Co-Authors: Suzanne Costello, Marc P. Y. Desmulliez, Stewart MccrackenAbstract:This paper presents a critical review of the traditional and newly proposed Test methods used for the measurement of hermeticity in packages with very small cavity volumes. Closed-form expressions of the minimum and maximum true Leak rates achievable are provided for the helium fine Leak Test method. These expressions are shown to provide practical guidelines for the accurate Testing of hermeticity for ultrasmall packages. A portfolio of hermeticity Test methods is also presented outlining the limitations and advantages of each method.

Leak detection methods for glass capped and polymer sealed MEMS packaging
Microsystem Technologies, 2011Co-Authors: Suzanne Millar, Marc P. Y. Desmulliez, Stewart MccrackenAbstract:This paper presents the limitations of the helium Leak Test when applied to typical MEMS packages. A novel closed-form expression is presented which allows the determination of the minimum cavity volume package that can be accurately Tested using the helium Leak Test method in conjunction with a standard gross Leak Test. This expression can be used to find optimum Test parameters for packages with cavity volumes greater than 2.6 × 10^−3 cm^3. Hermeticity Testing using FTIR and Raman spectroscopy are considered as potential methods to overcome the limitations of the helium Leak Test method.

Leak detection methods for glass capped and polymer sealed MEMS packages
2010 Symposium on Design Test Integration and Packaging of MEMS MOEMS (DTIP), 2010Co-Authors: Suzanne Millar, Marc P. Y. Desmulliez, Stewart MccrackenAbstract:This paper presents the limitations of the helium Leak Test when applied to typical MEMS packages. Hermeticity Testing using FTIR and Raman spectroscopy are investigated with a view to overcoming the limitations of the helium Leak Test method. Hermeticity Testing using FTIR is successful demonstrated for low cavity volume MEMS and glass packaged devices. Raman spectroscopy also improves on these limitations and can be considered to determine Leak rates caused by outgassing or permeation through package materials.
