DEK 260 LEDs

Electronics Forum | Mon Jan 30 17:42:50 EST 2017 | jrr3434

A few of the LEDs on the cameras of my stencil printer are really dim. I want to replace them and not have to buy a whole new light ring board. Does anyone know what kind of LED they are? Any info would be appreciated. Thanks.

Gotcha. We are a CM and we build 48" LED boards. But we buy all of our long PCBs off shore.

Hi Mike consider buying your LEDs from a value added distributor or sending the to a service house for trimming. It's no trick to cut so that one lead is longer than the other although you may have to pay a tooling charge. These people are equipped

We have this problem only with one manufacturer of LEDs. Avago LEDs give us the problems where SunLED and KingBright do not. We put a magnet under the embossed cover tape. The magnet is mounted to the feeder. Holds the part in the tape pocket. L

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

You might want to try baking the LED's in an oven for 24 hours prior to build. We keep our LED's in a humidity cabinet all the time, as we have noticed poor solderability if they are left out for too long. This may be even more important when buying

OK, this is what I'm talking about. If static is building up between the skin and clothing, how will wrapping it in a smock prevent it? The static is still there, the same charge, except know has a smock is covering it. Unless the smock is grounde

@ Sr.Tech, Most of our Chinese spares are Juki & Yamaha original & still bagged, just much cheaper. They wouldn't sell machines in China if all the spares and consumables were at European mark ups. Nozzle wise the Juki 750 & 760 copies are not 100%

Thank you for the answers to my questions. We are running two-lead LED insertions. Most of our PCBs are square between 9" and 14.25" in a 16 x 16 array, so pitch ranges from 0.52" to 0.90". Further complications are that most of the boards have th
