(1) product information content is big, this basically is reflected equipment is being produced in material of a solder is mix by many components thousands of main part composition, every component is comprised by many main parts again.
(2) product information structure is changeful, can be data information of structuralization, OK also dispute structuralization information.
(3) heavy and complicated of products plan process, it is one is refined from whole to the local, process that designs to in-house component from equipment surface modelling, containing information of numerous attribute, material, feature, contain many mathematical model and blueprint information.
(4) in solder material manufacturing facilities research and development makes a process in, branch of product research and development and craft branch can accumulate an amount gradually the giant, blueprint that exists with electronic form and documentation, to this kind of information share degree low, data delivers rate data of slow, business hard the level of management of compositive, data is backward. These problems restricted an enterprise to shorten directly the research and development of the product is periodic.
