Hello fellow Techies,



I have got a problem with shielding cans deformation issue. There are several kinds of shielding cans on board, we have found one shielding have deformation after reflow, one side of shielding lift and not solder on board.

We also do a test, bake the individual shielding in oven with 230 degree, the shielding still have deformation and two corner have lift. Take out the shielding from oven and temperature go down, then shielding go back to good.

Any one of you have experience on this case?

Deng
