(one step heat treatment),and the other is that the sample was heat treated first in the vacuum and then in the atmosphere (vacuum/atmosphere two step heat treatment).The microstructure of tantalum oxide film was analyzed by Atomic Force Microscope and Transmitting Electron Microscope.The I U ...
Arabidopsis thaliana Col-0 plants were transformed using the floral dip method (see “Materials and Methods”) and homozygous T2 transformants were selected for their ability to produce, in the presence of added furimazine, a strong luminescence signal following one hour heat-treatment at 38 °C....

This study investigated the effectiveness of heat shield placement locations during the rework process to avoid thermal and mechanical damage to adjacent ball grid array components and their solder joints on double-sided printed circuit board assembly. Three types of heat shield placement locations were...
