How to manufacture multi-chip LED?

[rajdes36]

Hi expert seniors,

I would like to know if multi-chip LEDs are being manufactured in India? What is the process, equipments needed? I think it should be something like SMT board assembling. In china, they use bridgelux, CREE, Epistar SMD LEDs and arrange them in the arrage as required. ATTACH=CONFIG]92614[/ATTACH]

I have done BE, MBA and would like to consider setting up factory instead of continuing with job. Please guide me in the right direction.

@tpetar: I am grateful to you for your prompt, informative help.
What you have sent is "making of single LED chip" which is domain of Bridgelux, CREE, EPISTAR, NISCIA etc. I would buy those chips from them and assemble the chips atop suitable heatsink base with gold wires in 3,5, 2*5, 5*4, 5*10, 10*10 array to make 3W, 5W, 20W, 50W, 100W multi-chip LED. (as shown in my post)
I need to know more about this assembly process, materials, equipments used.

Thank you Sir Peter,
You are very knowledgeable, resourceful and above all helpful. I aspire to be like you one day. The videos shared by you broadened my knowledge about the kind of processes, technologies used in the industry. The above video is for making single chip LED from Wafer, but process after 4:15 in video is relevant, I expect similar process to be followed for multichip with some more complexity.

with best wishes,
