Hi, I bought led chips and want to assemble them in a small array of 2x2, 3x3 or 4x4 using wirebonding and packaging. Do I need to connect the anodes of all leds in the same row together? Can I connect the cathodes of all leds directly to the ground or I have to use current sinks?
After packaging my leds, I need to design a PCB in order to drive them. I would appreciate if anyone can guide me through the process.
each led chip is operating at 470nm wavelength (blue), forward voltage of 3.3V @ 20mA.
