I decided to update a couple of P3's to version 2 because I am working on extended flight times and need the cooler running motors of that version. Of course, this involves replacing the ESC board to match the version. I won't even get into opening the thing up. As most of the experienced Phantom users know, the power connections are generally soldered, and this makes perfect sense. These need to be very solid connections.
The new ESC board comes with printed points intended to be tinned and joined with a tinned conductor. Now this sounds straight forward, but you need to see how small some of these details are to understand why I am asking this. Furthermore, I want to change my question. Is there a reason DJI isn't pre-tinning these contact points as part of their quality control?
The obvious answer would be that DJI is trying to save money. I hope that is not the case because this is a safety issue. DJI is far more qualified to tin these points than any consumer. It is far too easy to damage a circuit board with too much heat from a soldering iron. If those points came already tinned, there would not be much reason to apply much heat to the board.
As I alluded to above, I also think it is part of quality control. I know this by experience. My first Phantom turned out fine. My second one had problems that showed up during the tinning phase. Two of the pads for the LED's simply fell off. Then there is working with DJI on this, something I don't recommend.
I really am baffled though. I can't imagine any US manufacturer not pre-tinning something like that. I must be missing something. (not the fist time....) |
