Solder Beading

With Leadless Ceramic Chip Carriers (LCCC) it is more likely that any solder beading is due to placement. When the component is placed on to the solder paste it is forced under the body of the device. The LCCC termination and ceramic body are all relatively flat hence some paste displacement must occur.

Remember to also look at paste slumping as a cause.
