This design will provide a large repeatable solder fillet to the CHP resistor on reflow processes and will provide maximum heat transfer to the PC board in high power applications. By placing the CHP on the solder paste while the paste is in the "tacky" state, the CHP will be held in position until solder reflow begins. The pad design then uses the surface tension of the molten solder to pull the component to the center of the solder pad. The placement of a via rising above the board level directly beneath the CHP is not recommended.
