Most common BGA types

Dave- thanx for the suggestion and I have already downloaded the catalogs of both companies you mentioned. I am trying to narrow down the list for the BGA patterns most commonly seen vs. the shotgun approach of making one of everything, just in case.

We don't like ministencils. Consider using the patterns listed in the Practical Components and Topline catalogs. Few BGA we see have a 3X3 courtyard.

Hello all- I am am seeking information to the top 100 BGA grid patterns. I am planning to have a full sheet of stencil foil populated with these most common types. I will cut out the individual grid patterns and create my own mini stencils. In a 27

The first issue I see is that you have a high potential of the 402 tombstoning.

You're correct. This design will have a record amount of 0402 rework for tombstoning and misalignments. Suggest that the pads on each end of all components be the same size in order to balance wetting forces during reflow.

I agree with the previous two replies. This is a perfect design....if you're trying to create a graveyard full of tombstones.

Renco Power inductor (RL-1608-S-330) - common failures??

Electronics Forum | Wed Jun 09 14:41:12 EDT 2010 | ronchap200027

Has anyone had issues with Renco inductors failing. The component I'm having problems with is a 330uH shielded power inductor. Out of 36 board failures, I have 17 that failed because this inductor failed. Most often they end up reading -1.34 uH.

Are the majority of production lines around Chicago running Yamaha equipment? Or is another manufacturer more prevalent?

Fuji and Panasonic both have their North America headquarters in Chicago so I would assume they both have a large footprint in the area.
