Title: Need Help Bridging The Tactile Switch.
Post by: john.jenin on May 29, 2022, 03:41:06 AM
I failed to re-solder these 3 pins:

It's the pin for the tactile switch on the left analogue stick. Somehow I must have destroyed the solder pads for the pins. I have very little experience soldering and without a hot air station, removing the analogue stick was really hard. It seems like they were soldered on both sides of the board. Or maybe the solder melted to the other side. I don't know. 

So I was thinking maybe I could bridge them to somewhere. Anybody kind enough to point me in the right direction? I have looked at the board. The pins go somewhere on the top section but somewhere else on the bottom section. I'm kind of confused.

This controller actually has a drift issue. And if I press the L2 button, it will immediately move upward. I swapped the joystick and everything works fine except for the L3 button, which doesn't work because it was not soldered yet.

And my board is JDM040.

Would it be okay if I do this?

That Yellow jumper wire will do nothing. You need to reconnect the trace at the #3 point in your pic for that L3 line to be restored.

For the Blue jumper wire, run it from the #1 point you have marked there, over to the other stick at the same spot.

what rdc is correct but it would also help if you gave us a picture of the actual "damage" you did because it would help determine your problem better  :yess:

I have fixed the issue. Now the tactile switch is working.

In case anybody is having similar problem, this is what I did:

It appears that pins 3 and 4 (refer pic) are not required for it to work.

Thank you very much, @RDC and @LethalPrime, for being really helpful.  :hifive:

On that version board and that R3 the 3 and 4 aren't needed, but on other boards they can be or even use the Tact switch itself as the pass thru to make the connection there from 1 to 3 and 2 to 4, so don't assume that will work every time. ;)
