I was talking with a friend of mine the other day about component footprint verses component body size. He said the footprint is the body size, it this true? I always saw them as being different.
I am looking to use a water soluble solder mask. Some types of solder masks leave a conductive residue. This can not be tolerated due to the voltages, currents and frequencies. Has anyone used this type of solder mask and had a residue problem?
