Apple will launch the new Mac Pro at the Global Developer Conference (WWDC) in June. Some media surveyed major Apple dealers and Apple's website and retail stores. The survey found that for the 2012 Mac Pro, which costs $2,499, most of the retail channels are out of inventory or have very little inventory. Inventory tension in retail channels is a clear sign that Apple is preparing to launch new products.
In addition, Tim Cook said last year that Apple plans to release new Mac computers this year. Forbes had previously confirmed that it would include the Mac Pro.
FR-4 epoxy glass fiber cloth substrate is a kind of substrate with epoxy resin as the adhesive and electronic grade glass fiber cloth as the reinforcing material. Its adhesive sheet and inner core thin copper-clad board are important base materials for making multilayer printed circuit boards.
The epoxy glass fiber cloth substrate has higher mechanical properties, dimensional stability, impact resistance, and moisture resistance than paper substrates. Its electrical performance is excellent, its working temperature is high, and its performance is less affected by the environment. In terms of processing technology, it has great advantages over glass fiber cloth substrates made of other resins. This type of product is mainly used for double-sided PCBs and is used in large quantities.
