Soldering smd LED Cob TV back lights

[spike47]

Hi

Soldering smd 6v LED cob lights

I have already de-soldered and soldered 4 new ones back on some of the strips (x4 different strips ) it is quite easy using a hot plate

My conundrum now is,I have 3 more to do, the large area contact base on the chip is Positive, but the large area contact point on the strip is Negative, I didn't check the ones I have done before because they tested ok after soldering.

Hoping the pics will give you some idea has to what I am trying to say.

Cheers

Spike

Just buy replacement strips, cheap enough from China.
