For typical small sized circle LED panels, you can simply have a PCB routed to said circle... but when lighting fixtures are sizes 2-3 feet+, and a circular, typically how are the LEDs being spread across the radius? I can see flex LED strips being

I have assembled panels of 24"X9.5" LED Panels (24 strips of 10mm). I need to cut them into strips and join them together then add double sided 3M tape and spool them. How is this best accomplished. Laser Cutting, Die Cutting, Roller Cutting

We also have a few customers that seem to buy the cheapest LEDs available and provide them for the build. We've had complete reels that had obviously been exposed and oxidized. You can try a solder with a more aggressive flux. How long is your pro

I know this is a little outside of SMT production, but, I'm hoping someone out there can help me with a small issue. I have a product that I'm building that requires 4 .250" wires, with .125" strip on each end. I solder one end to the board, and on

I solder LEDs everyday from 0402 sizes on up. I work for an optical company so every product I make has LEDs. Some products have hundreds of LEDs per circuit. The problem is that clear materials are not filled materials and thus don't have the adv

SOLVED The LED/phototransistor was a little of the center on the "index wheel" (don't know a better name, its the gear that pulls the component strip). The wheel works with a LED from one side and a phototransistor from the other, through a hole on
