Claim 0:
1. A method of manufacturing a light emitting diode (LED) device comprising:
aligning a stencil comprising a plurality of openings with a plurality of pillars on a first surface of an interposer body of an interposer such that each of the pillars is located within an opening in the stencil, the interposer body further comprising two or more local fiducials extending from the first surface of the interposer body, and the stencil comprising two or more features to cover the two or more local fiducials, respectively;
resting the stencil on the local fiducials by way of the features such that the stencil does not contact the plurality of pillars;
stencil printing a flux material onto a pillar surface of each pillar of the plurality of pillars such that at least a portion of the first surface outward from a perimeter formed by outermost pillars is not printed with the flux material to form a first intermediate printed structure;
attaching an LED die comprising a die body and a first die surface comprising a plurality of light emitting diodes (LEDs) to the first intermediate printed structure with the flux material such that the flux material is located between each of the pillars and a second surface of the die body, the second surface of the die body being opposite the first surface of the die body to form a second intermediate attached structure; and
removing the flux material where it is exposed to form the LED device.
