Claim 0:
1. A surface mount device for a printed circuit board, comprising:
a first contact provided on a first side of the surface mount device;
a second contact provided on a second side of the surface mount device;
a first channel defined by a planar first side of the first contact and extending across a width of the planar first side of the first contact, the first channel having a depth of at least ten micrometers and a width of at least thirty micrometers; and
a second channel defined by a planar second side of the second contact and extending across a width of the planar second side of the second contact,
the second channel having a depth of at least ten micrometers and a width of at least thirty micrometers;
a first solder mask provided on an upper portion of the first contact; and
a second solder mask provided on an upper portion of the second contact, the first solder mask and the second solder mask having a thickness of between five micrometers and fifteen micrometers,
wherein the first channel and the second channel are adapted to prevent at least one of the first side of the surface mount device and the second side of the surface mount device from lifting off of the printed circuit board during a reflow soldering process.
