http://www.webelements.com/ The periodic table is a table of the chemical elements in which the elements are arranged by order of atomic number in such a way that the periodic properties (chemical periodicity) of the elements are made clear. The standard form of the table includes periods (usually horizontal in the periodic table) and groups (usually vertical). Elements in groups have some similar properties to each other. There is no one single or best structure for the periodic table but by whatever consensus there is, the form used here is very useful. The periodic table is a masterpiece of organised chemical information. The evolution of chemistry's periodic table into the current form is an astonishing achievement with major contributions from many famous chemists and other eminent scientists.

Chip On Board Tutoriel

Chip-On-Board Technology brings unique assembly options to the systems designer. In this technology the silicon die is glued directly to the surface of a printed circuit board between the die and the PCB or AL2O3 to establish the electric connection; a coating of opaque epoxy resin is deposited over the die to protect it against shocks and the harmful effects of light. As seen from the above figure, die is attached directly to the PCB, and wires are bonded to the PCB pads directly. The entire die attachment is normally encapsulated in an adhesive.
