<p>A method for manufacturing a light emitting diode in the shape of cup with a curved surface and planar bottom comprises two stages: in first stage, to produce a printed circuit board in the shape of cup, a printed circuit board is placed in a drill and is drilled to a cup shape with a curved surface and planar bottom using a particular mill at 12000-25000 rpm, after the drilling of other circuit hole is completed, the interior of the cup is fully polished using a sandblast device, and then is plated with copper ion, then is plated nickel and gold; in second stage, to produce an LED in the form of cup, the printed circuit board produced thus is applied glue, then a chip is fixed on the printed circuit board, and then baking, bonding, testing, injecting glue and baking are performed successively, thereby forming an LED with the shape of cup. The LED manufactured according to the present invention shows good performances, commerciality and many uses.</p> |
