I purchased this ethernet shield from a Chinese distributor off of ebay. Upon inspection it appears to have quite a few solder bridges on the WIZnet chip. I know that most of the pins on that chip are grounded so it may not matter if there are bridges but I am not confident that I would be able to figure out which ones are okay and which aren't. Is running a hot soldering iron across all of the pins the best way to resolve this?
I think I'd first get the datasheet for the chip and check that; I don't know enough about smt rework on what to suggest to fix it if necessary though - but I bet there are others here that would know.
Thanks! I checked the datasheet and cross checked it against the schematic and all of those pins are grounded so it should be fine as is. I am hopefully going to try out my first application with it tonight so we will see how it does.
I wondered the same thing with mine, but it seems intentional, also mine are bridged in exactly the same place. Puts my mind at ease as I haven't yet tested my board.
I also have the same board and the solder bridges appear in the same places as the photos. I have no problem writing to the SD card but haven't been able to get the ethernet working yet.
I received a replacement board due to the bridging and it also had the pins bridge. The new one worked immediately though. I must have had a separate issue.
