We're trying out 0603 packages on some 0805 footprints (at this stage only on some test boards) since our vendor tells us the 0805's are going to be getting harder to get, and more expensive to pay for. I understand the IPC footprint for the two is

Well Greg, I don�t know YOUR 0805 Pads but if you look at the recommended pattern for 0805 in IPC-SM-782 you might notice that the Z-dimension is somewhat about the size of your 1206 part length. With that and assuming that you ask if the results wi

Steve, This is a good, well repeated, not identified by IPC yet issue. I, and some others in industry, for years have proven and recommended smaller pads for various devices. I, and some others in industry, use 0402 pads for 0603 device types. IPC o

We've been experiencing solder balls on 0805 caps. We have modified the reflow profile and had some success, but some balling still persists. The balls always form from under the cap between the lands. I measured the distance between the lands at .03
