  1. Date + 2007-05-25 Customer + - Proposer + BMT Written by + Edan Han Classification + Confidential Paper PROPOSAL : Sputtering System for EMI Shield Coating

  2. [01:01] Equipment BS series is the treatment of industrial equipment for EMI Shield coating. The accumulated type of BS series is sputtering. Each procedure for BS series is finished in vacuum pressure. It is easy usage for the design of BS series. • Structure : • Chamber Unit+ • Vacuum Pump Unit+ • Vacuum Measure Unit+ • Base Unit+ • Accumulated Unit+ • Cooling Unit+ • System frame+ • Control Standing+

  3. [01:02] Testing The general testing item for EMI Shield Coating Film

  4. [02:01] Comparison Compare between Spraying type and Sputtering type + Vacuum physi-atmosphere accumulated method: superior adhesive+ no dust X 25 X 25 [Spraying type] Inspect it and find a lots particles of electric conduction on the tape. The particles make the steady of terminal products worse. [Sputtering type] No particles of electrical conduction on the tape. + High quality of film: High density + High pure+ No fault X 200 X 1000 X 200 X 1000 [Spraying type] This film includes a lots particles of electric conduction; therefore, the density is low and the shield’s effect is worse. [Sputtering type] We can’t find the particles. It looks like only one layer of the film which is high density and the shield’s effect is better.

  5. [02:02] Testing Picture-A The data for Strong Adhesive Sectional pictures express that coating film doesn’t peel off the casting of mobile. It means there is strong adhesive between mobile casting and coating film. Coating Machine : BS series

  6. [02:03] Testing Pictures-B Testing example of EMI Shield coating film [Adhesive testing] + Sputtering Method No particles is peeled from adhesive tape. That means it is good adhesive and good quality of the film.. Coating machine : BS series X 25 + Spraying Method A lots particles is peeled from adhesive tape. It has problems for the film. X 25

  7. [02:04] Testing Pictures-C Testing example of EMI Shield coating film[Spraying testing of salt water] + Sputtering Method(coating machine : BS series) x 25 x 100 + Hybrid Method (= Thermal Evaporation + Sputtering) x 25 x 100

  8. [03:01] Samples Why do you take sputtering type as EMI shield coating film ? + thinner film: High accuracy The film is thin and high density from sputtering type which makes the accuracy of EMI shield type. This is a main factor to take sputtering type of accumulated film. It is easy to control the quality of film. + In depth details and superior broadside, metal made The metal ion is sprayed to around coating film in the vacuum. Therefore, the sputtering type offers superior broadside of metal quality and is more easy to smoothly coat in each details.

  9. [03:02] Samples The samples is made by the procedure of BS series + Coating machine : BS series + Coating method : sputtering

  10. [04:01] Service for Customers The plan to serve customers + Operational training of Equipment :We install the system finished and arrange operational training on line for two week. + Specialized technology and management support : Offer the procedure message : Offer material message : etc. + Active service for customers : Within a half of year after installment, we will visit the customers and test coating machine each two months.
