I don't work on quads but I can give you some things to look for... Each of the moving axis work off a motor that is controlled by a "drive". Some of these drives have a fault or error output that is connected to the motion controller. One of your

My experience with different size boards and pre-heaters. The perfect world (right?) you would saturate the complete pcb with bottom pre-heat. But it is difficult with repair and rework equipment, not to mention the expense and foot print of large pr

YV100, easy... YV112 uses a dual work-area, dual gantry machine in which the gantry does X and the PCB-table does Y movements. Also each gantry can only work on one PCB work-area and can pick form only one side of the machine. Basically you have two

We've had poor luck with leaders - inefficient, not cost effective for the price of the parts usually. In my opinion, your best bet is to over-issue parts to a scrap # that works for you (all feeders are different as are machine scrap rates). This

Ah yes Mechanical Engineers. My previous company hired one Fresh out of College. Ink was still wet on his B.S. degree when he entered the shop. I passed by his desk. He had a CAD drawing on the monitor which he was feverously working on. It showe

I'm in North Attleboro, small world. To answer your question, you can deposit small dots of paste with a syringe. Kind of tricky work, and there are small stencil soluions out there fairly inexpensively. See http://www.minimicrostencil.com/ (I do
