Dear Bob, The Tessera microBGA technology defines a family of CSP devices. The most common microBGA type is the TV46 that has been selected by Intel for use with their flash memory devices. A microBGA package in general consists of the silicon die

I also have used square apps on the BGA's, this also allows for a bit more play in alignment of the ball to pad, I am interested in the reasons why to use round apps on 0603's and 0402's ???

Quad Align.....Cyber-optics....no difference...they both work well. Never tried a micro-bga but i know the upward camera does standard bga parts.

You should check the optical alignment and thermal calibration of the BGA rework station periodically [every six months]. Likely, the equipment supplier gives recommendations on this calibration effort, maybe in the manual.

Hi out there, I have an ongoing project in wich I have to use several BGAs. As I have no practice at soldering those components I want to take advantage of their self centering features . can any one gives me a tip on securing components? does any on

As you know 90% of defects come from the printer. This product is well worth the investment. You will improve yeilds and reduce rework. Very important with micro BGA's. Also lead free components do not self center (during reflow) as well. There is ve

Hi, Jacko is right!BGA ispection equipment like Xrays are extream expensive if you want a good system. There is some xrays that you can have low cost but if you are planning to do superBGA�s or want better image you need atleast 80-100Kv with good r

| I am beginer in BGA assembly and am confused in selection of pick and place option. As per book on 'implementation of BGA Technology-by 1995 aeic inc. states that BGAs reflow is quite forgiving and you need only Mechanical centering of PBGAs. The I

If I get you right and you are looking for a micro stencil for bga rework, then you should try http://www.circuittechctr.com. They are offering a free sample of their Flextac micro stencils in a wide range of sizes. The thing with these ones is that

When it comes to re-attaching the BGA onto the PCB, we don't those very nice mini-stencils. They are very nice though. On sources for your rework stencils, try your stencil fabricator will be happy to make those very nice things for you. What's wr
