I am designing a range of electronics packaging. Can anyone tell me where to find the dimensions of a VMU "C" sized circuit board?

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

Hi All, One of my customer has provided a pcb design having common pad for 0402 and 1206 package(i.e 3 pads in the gerber, pad1,pad2 belongs to 1206 package and pad2,pad3 belongs to 0402 package) Will this create any solderability issue. Is anyone e

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.

Hi, I always find difficulties of getting the SMD package dimensions as per the package type. Could there be a library which has all the SMD package drawings with dimensions? If yes where it is? If no what is the best way to procure such information

IPC-7351 is the most complete I have found but is still missing some. Look here http://www.ipc.org/contentpage.asp?Pageid=4.6 Jerry

Could anyone tell me where I can find some literature/standards describing the dimensions and solder land sizes of all common SMD components available in the market? IPC-SM-782 does provides some but not all. Thanks in advance for any response. Rega
