With a 7 thou stencil, we'd go 1 to 1. So for a more typical 6 thou stencil, we'd bump the aperture area by 1.15, maybe 1.2. We make no distinctions between 'innies' and 'outies'. Are you talking about castellations on land grid devices [ie, BCC�, L

Castellated is the easiest lead design. Anything longer than the out side dimension of the part should be OK. However, you will never get an inspection person to say it looks OK, yet the solder joint occurs on the bottom side of the part - like a B

Can anyone give me the virtues of SMT package castellations vs. no castellations with particular reference to the ruggedness and reliability of the solder joints? Any references or studies that you can point me to? Also, although I'm in favor of pr

I have some CERSOT-23 transistor packages with castellated terminals. The 4th lead (drain castellation) is electrically connected to the top of the device by the castellation. The castellation goes up the ceramic body and contacts the metal package

I am student at Northern Illinois University and am doing a senior design project on applying castellated solder pads (pads on the side of the substrate) to a hybrid circuit. I have had difficulty finding related articles. I found this website and

Soldering Issue in Sensor component

Electronics Forum | Fri Dec 27 13:16:18 EST 2019 | slthomas

Can you describe the failure mode of the soldering defect, i.e., is it failing to meet the height requirement for a castellated termination due to not wetting of the component terminations, or not wetting the pads sufficiently, or....? We install a
