We own a vibration table and drop test machine. This is used in the context of testing packaging against shipping damage, I am not sure from your post what context "vibration" is to be used in. Perhaps this post is completely irrelevant to your tests? The vibration table is a large steel table, big enough to set a refrigerator box on, with a shaker motor that vibrates the product for a certain time. The shaker motor is probably 1.5HP, and makes quite a noise. The whole thing is anchored to a concrete slab and shakes the bejeebers out of anything nearby. The drop test is a standard test developed by ISTA (I can't remember what it stansds for other than International Shipping somethingorother) that tests packaging integrity. You set the product box on it's corner on a set of trapdoors, and drop it a prescribed distance on a steel floor a prescribed number of times. The product is supposed to come through these tests unscathed. I know that there are vibration sensors available (Omega?) but don't know much more about them. I am real curious how you are going to go about generating ESD. Are you goping to zap components, or assembled products, or something else? -- Lawrence Lile John Voth Sent by: pic microcontroller discussion list 07/23/2003 04:48 PM Please respond to pic microcontroller discussion list To: PICLIST@MITVMA.MIT.EDU cc: Subject: [EE]: Vibration and ESD testing? Howdy PicListers! I'm doing some research on vibration and electrostatic discharge testing in preparation to build some test equipment. I am wondering if anyone out there has some experience building a vibration table and/or building an electrostatic discharge tool?
