Hey all, Optimizing a really tight circuit and being able to drop even one 0805 would be a noticeable relief. The board is setup for various configurations (circuit variations). In one part of the circuit, one configuration requires a SOT-23 voltage reference (such as LM4040) and another configuration requires an 0805 resistor. But never both. Actually, pins 2 and 3 of the SOT-23 (the two pins that are on the same side of the SOT-23 package) are the same signals that are on both ends of the 0805 resistor, and I can actually fit the 0805 on the SOT-23 pin 2 and pin 3 pads. Great, I can drop the 0805! But how do I handle this when I pass the board to a CM? Will they willingly accept this placement, or throw it back as non-standard? What if I overlap these two components on the board layout? Ignoring layout-software warnings/errors, is this acceptable practice? Final option is to create a special component that I define are being able to hold an SOT-23 or 0805, but not sure if this is enough to appease the board houses.
