Electronic coating is a technology to produce thin film materials In the vacuum chamber, the atoms of the material are separated from the heating source and hit the surface of the plated object
In recent years, electron beam machining and ion beam machining are new special machining which have been greatly developed They are widely used in precision micro machining, especially in the field of microelectronics Generally speaking, electron beam
With the promotion of the "leader " plan, higher and higher requirements are put forward for the conversion efficiency of photovoltaic modules The upgrading of module technology constantly reduces the packaging optical loss and electrical loss from the
4 pieces of pretreated aluminum with the specification of 200 mm × 144 mm × 03 mm shall be selected as the substrate Before coating, vacuum the sputtering chamber below 80 × 10-3 PA to reduce the influence of impurity gas on the film quality After that,
In high vacuum, after heating, the electron gun filament emits hot electrons, which are accelerated by the anode, and a large amount of kinetic energy is obtained to bombard the evaporated material The kinetic energy is converted into heat to heat the ev
Engraved mold (material copper, steel, nickel), also known as the original mold Mold and parts are reversed It is processed by stereo engraving machine or precise CNC The thickness of the original mold is determined by the electrolysis time and current
