Since the printed circuit board is not a general mobile phone terminal product HDI boards, so slight confusion in the definition of the name of, for example: a personal computer with a motherboard, known and not directly called motherboard circuit board, although the board has a circuit board exists but is not the same, so when evaluating both the industry can not be said about the same. Another example: Because there are integrated circuit components mounted on the circuit board HDI board hit model handsets, so the news media referred to him as the IC board phone HDI board which company is good, but in fact he is not equivalent to a printed circuit board. Shenzhen Electronic Technology Co., Ltd. Newell HDI imaging introduce two 3 low-cost operation. This is the main requirement for any manufacturer's production. Early LDI mode or require the use of conventional dry film into more sensitive dry film HDI board phone details of the deal, so as to achieve a faster imaging speed; LDI mode or under a light source used, the dry film into different band. In all these cases, the new dry film often than conventional dry film manufacturers use more expensive. 4. compatible with existing processes and production methods. Production processes and methods typically are carefully prescribed and thus to meet the requirements of mass production. The introduction of any new changes to the existing image forming method of the method should be minimal. This includes changes in the use of the minimum dry film, have the ability to solder mask layers exposure, production requirements traceability functions and more. Phone HDI board processing, Dazhou phone HDI board, Newell Newell hit by the Shenzhen Electronic Technology Limited. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) strong, credible, in Shenzhen, Guangdong printed circuit board industry has accumulated a large number of loyal customers.
