## Procedure
|
||
|
|
|
||
|
|
1. Secure the PCB in the cradle above the ZT-1 airbath.
|
||
|
|
|
||
|
|
1. Use an anti-static brush and the no clean flux to apply the flux onto the contact leads of the component.
|
||
|
|
|
||
|
|
1. Turn on the airbath to warm. It will slowly heat up to 150 C.
|
||
|
|
|
||
|
|
1. Take a strand of de-solder wire and melt it directly onto the leads of the component. Can be liberal and use as much as needed to cover all the leads.
|
||
|
|
|
||
|
|
1. After a couple seconds, the de-solder will fully melt onto the leads.
|
||
|
|
|
||
|
|
1. Pick up the ZT-3 Airpick. Place a finger over the hole to create a vacuum.
|
||
|
|
|
||
|
|
1. Use the airpick to pick up the component. Release your finger to drop the component.
|
||
|
|
|
||
|
|
1. Use a foam swab and the no clean flux. Gently use the swab to push the de-solder blobs into one bubble.
|
||
|
|
|
||
|
|
1. Use a vacuum to suck up the bubble of de-solder.
|
||
|
|
|
||
|
|
1. Use the foam swab and no clean flux to apply a light coat of flux to the area.
|
||
|
|
|
||
|
|
1. Switch the airbath to cool.
|
||
|
|
|
||
|
|
1. Use a foam swab and the non-flammable flux remover to apply the remover to area. It is recommended to apply a second coat.
|
||
|
|
|
||
|
|
1. Turn off the airbath and remove the PCB.
