Are you absolutely sure the problem is with the humidity? We had a problem with 3528 size leds, damaged by the pick and place nozzle because a 0.2mm mistake in the height measurement. Also, we found that several suppliers are using fake desiccant ba

Thanks for that Steve - I'll try anything at the moment, but that sounds like a reasonable suggestion. I've already replaced a few cables that looked dodgy, and the LEDs on the LED rings, but I've not done a ribbon cable on the head yet. I shall hav

Hi all, We had a servo amp replaced (SA-6) and the machine worked with no problem for the first panel (this panel of 10 only needs a TQFP100 from the MTU). Then I got the "Servo NG" error again. One of the servo paks showed a "7" on the LED. The err

I have a Fuji IP1 using the MCS control system. Everything works fine, but it seems to have tons of problems placing PLCC4 parts (Osram Power TopLED). Some reels I load up it will give a vision processing error for about 1 out of 10 parts. Other r

Maybe you have to contact your machine support they can modify special nozzle for that component...i dont know what else you can try...or just contact your support and ask them what to do...we had a similar problem with LED diode on our machine..and

Is the nozzle used to pick the offending used to pick other parts in this program? Have had experience where the LED's inside the nozzle backlight have broken down causing Vision Processing errors. And worth making sure that the brushes on the head a

2, I have to scroll down to the bottom to see the image... and the outline of the legs isn't very clear. The legs are sort of blurred together. I had tried lowering the CCD offset in the part definition to -50, but it still looked bad. Could this

Should be do-able. Check out a couple of things: 1. Temperature tolerance of the LED's. If they can't withstand reflow, then you won't be able to do it. 2. Height of the LED's versus the travel of your pick/place. If your pick/place head won't t

Here in this circuit LED is placed at the collector. i am with an impression that, IE=IB+IC. so it is better to keep at the emitter, right ? all the gain of the transistors are not utilized. What is the purpose of LED, placing at collector? Please e
