Placing bigger chips

Post by tdarlic »

Hi guys
I am planning a first job on the Liteplacer. I created a trays for tapes. Tested the placement from tapes to test boards and 0603 placement is good enough. I was setting it up last night and came to TQFP44 chip. It is essentially 12 x 12 mm chip. I 3D printed the tray to hold the chips but I couldn't find how to put that into the software so that the down camera looks at the chip and picks it up. Can Liteplacer software do that at all? Was I just too tired to get it?.
Also it seemed to me that the camera is missing the more vision filter options. In the tapes setup there are only 3 vision setups to choose from (paper, black plastic, transparent plastic). For all of these I use filter uses zoom but when I try that for the TQFP44 the chip fills complete camera field.
Could someone point me to the right direction?

Thanks for the link.
I totally missed it. So there is no vision for the tray chips, you need to make a jig to be very precise. I plan too CNC jig with the holes so that I can use the vision make sure that the jig is in the right place.
