Dissemble the keyboard.





Prepare the keyboard 9 rows  joint points by tinning them.




Prepare the 9 Dome row sets by tinning the joint points on both sides.







Put back the 9 dome row sets by soldering them to the keyboard 9 rows joint points.











Re-apply the plastic cover to the 9 sticky dome row sets.





Testing. No bouncing and no missing keys.
