Question: I am going to start placing 3mm x 3mm plastic smt leds and want the absolute lowest errors caused by the nozzle either dropping or allowing the part to shift. Would a 2.5mm nozzle be too big for the 3mm part. My logic is that the more surfa

What type of machine are you using? We have a panasonic MPA placing LED's. I would have to check which nozzle we are using. Despite the odd shape we don't have problems with them. And don't forget that parts can shift in the oven. Usually for the

Hi Tony, as you might guess, a Nozzle Mfg. has stepped into this conversation. Having worked with many small, mid-size, and Fortune 500 companies for almost 15 years we have seen many "parts" pick up challenges. We were the first to offer "Complia

It's been years since I worked with a Fuji. I only once resorted to the undocumented part class 255 (or whatever they call it) and that was when I was working midnight shift. The smaller nozzle working better than the larger nozzle makes me wonder a

i just thought that it because of difference thickness between the silkscreen and without silkscreen. if we apply the same pressure and dispense time to this two difference location, the glue size will be difference. location with silkscreen will rea

Hey Thanks! Yep, they are pricey but I think it would be a worth while expense to safegaurd $250,000 worth of leds! I will tell the powers that be and see if I can squeeze out some cash. If I scrap one loaded board could I use it for profiling 20 to

I amusing a Fuji CP3. The part data seems to be the easiest part for me, 3x3 square. I went with the 2mm and had LOTS of dropped parts. A 1.3mm worked MUCH better, between 1 and 2% loss. My only problem now seems to be profiling the oven. The specs o

There seems to be less play in the pocket than with other parts i've loaded. I was assuming the large nozzle would work better but for reasons unknown to me it didn't. I also tried a 1mm and had parts all over the machine (can you say hand place 100+

I guess no one at ECD reads this forum. They make a clip-on thermocouple prob. Where I used to work we had 3. At first I thought they were very awkward to set up. But once you practise a bit and get used to the right hand thread tightening screw

The nozzles get centered at zero degrees and 180 degrees. I believe the yellow asterisk is the measurement at zero degrees, when it rotates to 180 is when you will get a red X or a green O. (In other words the yellow asterisk is normal) I think you
