Hi there ! I am currently facing the same problem as mmejia04 : I have missing pads after a “not very well conducted desoldering” of the connector. I have 15 pads missing… Here is a schematic of my motherboard connectors :
Thanks to bert.harmidomski, I could identified some of the test points I have to make some jumpers to… However, I still miss some data as the iphone 6th gen is not available in Phoneboard… Here is a picture of what I want to do and of what info I miss…
Could you please help me figure out which test points I need for the missing pads (and correct my picture if I did anythhing wrong as I am a total noob in ipad repair…). Or tell me where I can find the schematic of the ipad 6th gen to load in Phoneboard… Thanks in advance Best regards
If you have a mulitmeter, you can check this for yourself. I will also mention, jumpering all the way to the test points may not be necessary depending on how much of the trace was pulled up. Think about how the connection got to the solder pad in the first place. There’s likely some of the trace that feeds into these left. You can scrape away some of the solder mask that covers the actual copper board trace (be gentle, since it’s fragile) leading off of whatever pad. You can solder the jumper to that, even if it’s just for added stability. You can also use the exposed copper to check the surrounding test points for continuity with a multimeter. If your multimeter doesn’t have continuity mode (mode do) you can use check for close to zero resistance.
That being said, this should fill in your missing info. This is a less than ideal layout for jumpers, but these are at least the test points which correlate to your missing lines. I used green for the test outer row of pads so they're a little easier to distinguish.
I will also mention that ground pads are generally not necessary to jumper. You can for completion's sake, especially since there are quite a few pads missing here, but it's not necessary to have all the ground pads present.
