When are conveyors required

Electronics Forum | Wed Jul 24 12:03:10 EDT 2013 | rway

I agree with JDengler. It is easier to service a machine if there are conveyors between them. You need to also consider how the units get transferred, SMEMA signaling or some other method. Some equipment doesn't support this and an output conveyor

Hi Aharper, We have an EKRA E5 too and starts to do this error "machine offline" like yours. I chequed like you say, the SMEMA ports, but seems all is good. You can send me the service Manual if you have it?, any clue on that error you can explain m

SMEMA Interface minimum requirements

Electronics Forum | Fri Oct 18 15:29:16 EDT 2019 | kylehunter

Hi all. We are currently trying to build a downstream bypass to have our final conveyor feed into our oven, which doesn't have a SMEMA interface. Right now we have to manually connect the two downstream ready pins by hand. I have a good idea of how I

I have problem in Jot Automation inspection conveyor. The Problem is that the Good board has to go in down side conveyor & Bad board has to go in upside for rejection or rework. It is unable to separate the good & bad boards. Kindly refer the attachm

DEK SMEMA to UIC Conveyor

Hi, I just read your post. I think I know what's your problem is. In the DEK 265 (I assumed that is the model?)There is a special card for such things. For. ex. Fuji interface, Panasonic, Siemens, and UIC SMPI - interface. Uninerversal has therir own

Melted BGA part

In electronic manufacture, it's never good when "oozing" is part of the conversation. "Bridging" that's bad too. "Melting" sometimes good, sometimes bad. Got pix? How about some nice color pictures?

Fiducials

Electronics Forum | Tue Jul 06 12:25:54 EDT 2010 | isd_jwendell

I agree, setting a standard for the pcb fab shop is good. I use a fiducial a little smaller than the spec you mentioned, I use 30 instead of 40 mil, which is the minimum recommended for my machine. The rest of the spec (SMEMA Standard 3.1) appears th

poor print definition

Electronics Forum | Tue Feb 21 09:19:50 EST 2006 | Chunks

Hi Mark, Not to be condescending, but is your 265 camera in focus? I've seen one instance of this. If it�s not the camera, and you are sure all your other parameters are good, , then poor definition can be from bad snap-off or bad gasketing. Snap

Bad business practice and disrespect to SMTnet

Electronics Forum | Thu Jun 06 18:16:58 EDT 2019 | davef

The nerds say they've fixed the problem. They say the problem was caused by bad, obsolete code. Based on my review, I believe that they corrected the problem. Good job nerds!!! Hopeful, our faith in man [and woman]-kind is restored with this fix.

Mirae 1030 Y-Axis error

More than likely the encoder scale or read head has an issue. Many times.. oil/dirt/water get on the scale and cause a bad spot or bad area. Try to clean the scale with a lint free cloth and alcohol. You should also be able to see the read head and m
