Q1) How to identify on good or bad RF shield that could contribute to dewetting? A1) We use Alloy 770 and 752 [German silver] for our RF shields. We have never seen a solderability issue, even aged stock solders well. * Nickel Alloy 752, Nickel Silv

In line with the previous poster's comments, * BIG SMT EMI shields are tough to reflow. * SMT EMI frame and snap-in cover [after reflow] shields work fine. The SMT EMI shield design that we like the best is from Instrument Specialties, EZ Peel PCB

I think there are several answers: 1)Design Fail - slap whoever created it 2)Fit that connector as a manual process after the PCB is finished. 3)Print side 2 using a jet printer 4) Shield the fragile LGA and reflow it twice anyway. 5)Use a thicker PC

Since the inductor is electro-magnetic, that means the device is composite of coil and ferrite metal. The inductor inside the reflow oven meets with blower motors which close to the inductor and generate magnetic field. With such conditions, Lawren

We have used these shield clips from Autosplice to good effect. The clips are placed and reflowed on your SMT line and the shield fitted before test. It depends on the demands of your product as to whether these are suitable. http://www.autosplice.c
