Fast Turn BGA Reballing Technique Developed

Recently BEST has developed and perfected a reballing technique for area array devices which is designed for speed and fast turn-around of small quantities. The tooling is designed and fabricated at BEST. The stencils are custom made for your device patterns using the BEST laser. After applying flux to the bottom of the part, a polyimide stencil corresponding to the size of the balls and part pads is aligned over the part. The properly sized solder balls are then poured into the apertures with the fixture keeping the StencilQuik(TM) stencil affixed to and aligned with the part. The assembly is then reflowed, cleaned and inspected. This technique is one that is straightforward and is used when a moderate number of the same part pattern reballing is required. The tooling and stenciling is designed for multiple reball cycles.

MicroSoft VISTA Still Buggy, Several Flaws Exposed

As expected by now the upcoming Microsoft O/S is facing an early crisis of confidence in the quality of its soon-to-be released Windows(TM) Vista(TM) operating system as computer security researchers and hackers have begun to find potentially serious flaws in the system that was released to corporate customers late last month.
On Dec. 15, a Russian programmer posted a description of a flaw that makes it possible to increase a user's privileges on all of the company's recent operating systems, including Vista. And over the weekend a Silicon Valley computer security firm said it had notified Microsoft that it had also found that flaw, as well as five other vulnerabilities, including one serious error in the software code underlying the company's new Internet Explorer 7 browser.

From what is the "word" here are five things you'll hate about Windows Vista

1. Your current hardware won't fully run Vista - Get ready for the media blitz. Get ready for the frustration. Although many computers in use today will be able to update and run the new operating system, they'll only be able to run it in what Microsoft slyly calls 'Windows Vista Basic'. In this mode, you'll have the ability to search files but you won't have 3D Aero graphics, live animation along the Taskbar or smooth streaming graphics on your desktop. Unless you buy a new PC sometime in 2007, or add a high-end video card and some extra memory to your current PC, you probably won't get the full visual Vista experience.
2. Vista's Aero graphics eat laptop battery power - If you're used to your laptop lasting on a long journey, you might want to reconsider upgrading to Windows Vista - that is, if you want the new Aero graphics features turned on. Unfortunately, changing from Aero to Basic is harder than it should be.
3. User Account Protection - The User Account Protection feature has already had plenty of negative press. See the above comments on this point. For most of us, the frequent appearance of User Vistas' Account Protection on common tasks will be security overkill.
4. Missing drivers and incompatible applications - Not having all the necessary drivers or not having software compliant with a new operating system is to be expected in the beta of a new OS but this situation still exists even after several months of developer testing.
5. Troubled sleep - Microsoft claims that it has addressed the complicated issue of whether to put your laptop to sleep or have it hibernate when it's not in use. Instant Off, a new option on the Start menu, allows Windows Vista to take a quick snapshot of your system, then shut down completely, thus eliminating the occurrence of a hot laptop inside your backpack.
This upgrade will take years to implement and gain acceptance......
