Plastic Hermetic Packages for MEMS?
The sealed hermetic package is over 100 years old if we include cathode ray and vacuum tubes. While the package has changed, the idea of making a near-perfect gas-tight enclosure has remained constant. The metal and ceramic full hermetic package may be required for applications that cannot use the non-hermetic plastic package, but is there an intermediate package choice? During the last few yea...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
study the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولEnvironmental Stress Testing of Power Transistors Encapsulated in Plastic Packages
Power HEXFET transistors encapsulated in TO-220-style and SOT223-style plastic packages were subjected to preconditioning per the JEDEC JESD22-A113 standard, which includes solder reflow simulation and flux application, and to environmental stress testing: highly accelerated biased temperature and humidity test (HAST) and multiple temperature cycling. Electrical measurements and C-SAM mode acou...
