Hi all,

Is there any Mirae 1030P users that could help us out with some questions we have?

Thanks...

questions I asked:

“It seems the vision system is not reliable. However, we need to get the procedure to create and debug fine pitch parts such as BGAs anf QFN’s to understand how the machine operates.: Common errors: • Even after doing the vision test of the part succesfully before production it does not mean the part will be placed, the machine rejects 100% of the parts in some cases. • Some cases the vision test is okay, the machine runs okay during some boards then just starts dumping the parts as if this part/shape was never placed/tested before. • The system sometimes does not save some of the changes like pick up height or a number of the leads. • Pick up retry - we have no control over this as the machine retry’s pick up 3 times no matter what figure we input in the feeder information..Is there and machine setting which overrides the feeder information?

In short, we do not have control or total understanding of how the vision process works. Is there an engineers manual for vision processing available for 1030P?

The software on these machines is kinda flakey and the manuals are almost useless. There are a lot of bugs in the vision software that bite you. I supported mirea/meridian equipment at a past job and my memory is a bit fuzzy, but here are a few things I remember.

· A lot of the categories in the vision database just don’t work. Most parts should just be taught as a chip capacitor or as an soic. For QFNs, I remember I just taught them as a PLCC.

· ICs with missing leads didn’t work right. I remember having to set the pickup rotation 90 degrees off to make it work. For some reason…

· For a lot of larger parts you need to go to the pick and place program and manually change the vision so that the part is centered over the camera. I don’t remember exactly what it was called but it was a drop down menu, change it to center. What’s going on there is that the machine likes to center two spindles over one camera at a time, i.e. spindle 1 and 2 will position over camera 1, etc. it does this so it can image two parts at the same time. This is fine for small parts, but with larger parts, the camera can’t see the who part.

· Again, I don’t recall the exact name of the menu and function but when you are using the part model teaching utility, if you scan a part a second time, it will reset the orientation back to zero, you’ll notice the little drawing on the screen will have rotated. You have to reject the part and pick another after each attempt at scanning.

· Sometimes the lighting brightness defaults to zero and you have to manually go in an set it. Setting it to 1, is usually sufficient.

Basically it comes down to a lot of trial and error, and you need to be aware that a lot of the menus and options don’t do anything or don’t work the way they should.
