Enter A value of -1 in the Tray pickup X & Tray pickup Y fields. This will disable the automatic empty tray pickup by the machine. I would recommend getting a data sheet on the tray from the component vendor for accurate pocket & tray dimensions. Var

Hi, SMTnetters � Does anyone have any information on waffle trays, is there an IPC guideline for the use of these? I am experiencing a universal GSM dumping trays with parts still in the trays and I suspect the tray data will require amending if the

My thoughts on metal trays: One problem with a metal tray relating to ESD is its conductivity. Most trays are conductive but have resistance or a disipative nature. If you were to place a "charged" component into a metal tray that had an uncontrol

Hi There Just set your Tray Pickup X and Y to -1. This way, the PTF wont reject your tray but you will need to remove manually the empty tray. It's a little bit longer but you wont have any broken pieces. Seeya! Steven

Thanks Dave, The reason I want to make one in-house is cost. This is not a standard part and after contacting a couple of vendors ($1,000 plus for first tray) I decided it would be much cheaper to do it in house with our CNC.

Scotty: If you have excess CNC machine capacity, it might be economic, but if your machine and design resources are loaded-up the $1000+ sounds cheap. [Just another voice screaming in the dark.]

Does it have to be made out of plastic? Wouldn't some stock aluminum plate with milled out pockets work just as well? Would the aluminum offer the same, better, or worse ESD protection?

Where is the best place to get exact dimensions for waffel trays? The trays themselves give the support dimensions n each pocket, but as you know, having the exact pitch makes it quicker to program a tray,by eliminating the measuring and estimating o
