Product process of cob chip
Putting the heat conducting epoxy resin covers the surface of the aluminum substrate, then put the silicon chip into the aluminum substrate, the silicon chip firmly fixing the aluminum substrate with heat-treatment,
then cilicon chip and the aluminum substrate build relation of electrical connection using wire welding

Advantage and drawback of high power cob

Advantage
Compare to single LED, the cob light source can save that once packing cost and twice grading cost. the same function in lighting device system,
the cob can cut down 30% cost of light source through actual measure,
this is great important significance to promote COB to application market.
in performance , via reasonable lens design , cob module can avoid dazzle,
in application, the product and install of cob module is simple and convenient, so it can cut down product cost. with the lighting market gradually increase , the cob light source will be mainly production .
