AI Power Connector Reflow/Repair

The first batch of 1000 AI cameras have substandard soldering on the power connectors and these need to be reflowed.

Reflow

It is not necessary to to remove the board from the case to reflow the connector

  • Reflow the connector pins
  • Clean the area with alcohol and Q-tip


Repair

Also the connector can be broken off by over tightening the power cable or tampering in the field and may need replacement.

  • If the connector is broken off snip the bent leads on the connector side so they are flush with the board
  • Heat each of the leads/pads on the opposite side of the board and remove the leads with tweezers.
We do it this way so more solder is not pulled into the through hole making it more difficult to clear the holes
  • Clear the solder in the holes using solder wick. Be careful not to overheat the board or the pads might come off
Remove the solder from the other 5 holes and as much as you can from the ground hole.
One of the holes may not clear because it is connected to the ground planes. Just clear the others, hold the new connector in place and heat that pad until the connector is fully seated on the board.


  • Clean the area with alcohol and Q-tip
  • Apply a small amount of flux to the pins on the replacement connector
  • Align the new connector and heat the ground pin melting the solder and seat the connector.
  • Solder all of the pins
  • Clean the area with alcohol and Q-tip
