6 ·The photolithography process and the etching process are repeated several times on the wafer layer by layer Here an insulating film that separates and protects the stacked circuits is required It is called a thin film The process is very similar to manufacturing a Multilayer PCB 5 Deposition and Ion Implementation Ion implantation
·Summary：The production of aggregates generally includes several main processes such as crushing screening sand making and sand powder separation Although the overall processing technology of aggregates has become more and more mature the specific process flow of aggregate production varies depending on the production scale raw material
Sand casting is one of the oldest and most widely used methods of metal casting dating back to around and even before 10 000 BC The process employs sand for the main mold material as this material can be shaped and compacted to form a variety of complex and large cavities for molten metal that will eventually be turned into metal castings for a host of different
·The sand production line is a special device used to produce construction sand and stones and it can save as much as 50% of the energy compared with the traditional sand makers The sand making plant can make stones sand and pebbles to construction sand with all kinds of fineness featuring uniform particle and high compression strength
·Dolomite Sand Making Plant Flow Now that we have introduced the new sand making machine production line handles dolomite and the configuration issues of the production line in dolomite treatment let s introduce the specific process flow of the production line in dolomite treatment The first step is the rough crushing production of dolomite
