Those of us that work with many diodes know the look of the back of the diodes from the two different 6X sleds available to us.
The diode from the GGW-H20L has the distinct green "splotch." The diode from the SF-AW210 has a large square "bar code" that looks, to the naked eye" just like the square bar code on a PHR.
Well I was harvesting GGW-H20L diodes this evening and guess what I found? -- the diode used in the SF-AW210 in a GGW-H20L sled!
Yes, I am sure. I double checked when I saw it. When I saw the square bar code the diode was still in the heat sink from the GGW sled.
We believe that the SF-AW210 is not quite as "tough" or as consistent as the GGW-H20L. When you are harvesting 6X diodes, you need to be mindful of which diode is coming out of the sled.
