Formflex. Carefull now, If you already have components on the underside of your pcb, i.e Large radial components the scope of the formflex may not be large enough to cope. Check with DEk for the speck as I can't remember the limits off hand

Has anyone used or had any experience with Fuji & Quad for large board assembly? What is the maximum board size that a Fuji & Quad can support? Many thanks in advance.

I've used Fuji for fairly large boards. The largest pcb size is 20" by 18" for pick and place; 18"x14" for chip shooters. I've never used Quad. N

cap and resistor Parts are cheap! $10 vs. $20 or so? If you are worried about inventory cost than only buy your top 10 or so runners in the large reels. I am a big fan of large reels for the high running caps and Resistors.

Does anybody have a slick way to hold down large inductors? Like 2 to 3 inches in diameter. There must be something better than ty-wraps and RTV.

Air inclusion in solder paste

You mention "large ground plane pads in the center". Could it be that these large apertures are allowing the blades to "dig" which somehow pulls paste from adjacent apertures as the blades recover?

Thanks for the suggestion. The large ground pad appears as a single large pad on the component and PCB but we print a matrix of 28 small dots of paste to provide the solder for the joint. The inconsistent volume transfer can occur on any of the fo

Which nozzles are coming up NG on the large camera? If it's the smaller ones, don't worry about it. Those nozzles don't use the large camera anyways. Be concerned if the small nozzles are coming out NG on the small camera.

Streaking at Screen Printing

Let me get this straight. You have large apertures for some reason? If this is the case you could try making the aperture like a screen, many small apertures to support the blade, rather than one large aperture that allows the blade to deflect.
