Fuji IP3 Problem

Electronics Forum | Wed Aug 23 12:04:32 EDT 2006 | fastek

I am going to be scrapping out a 1997 IP-3E soon. It is a complete machine EXCEPT for the 4800 vision card. If there are cards you might need and don't feel like getting hosed by Fuji, let me know. Rick

Streaking at Screen Printing

Electronics Forum | Tue Dec 19 10:25:38 EST 2006 | slthomas

I'm not familiar with that printer so not sure of the support config., but can you plug the openings in the product with some pieces of scrap board (not likely on support pins but workable on a plate) and look for a difference in performance? Does t

Fuji IP3 Head squealing

Electronics Forum | Wed Dec 20 07:08:51 EST 2006 | cyber_wolf

We have had this happen. The Z-ball screws do go bad in IP3's. We replaced the ball screw and the problem went away. As mentioned improper belt tension will cause the servo to make loud noises. But if you say the movement is rough, then the ball scr

Solder contamination on Golden Finger

Electronics Forum | Mon Aug 13 10:39:35 EDT 2007 | dphilbrick

If you can not find the source of cotamination then apply masking to fingers until you do find source, single layer of Kapton tape or similar should not affect print thichness. This will eliminate scrap / rework in the mean time.

Manual repair of solder joints

Electronics Forum | Tue Oct 21 12:10:04 EDT 2008 | jdumont

Do your boards only have three parts on them? Otherwise, i dont see how this is possible. Do you scrap the board if there is an issue or do you fix it and make it look like reflow soldering?

DEK Stencil image offset?

Electronics Forum | Fri Jul 24 02:57:05 EDT 2009 | fede

I use Center Edge, and adjust stencil offset. It's very easy, you just have to give it the PCBs width. An other advantage is that If your PCB has scrap strips, and you lose them, or PCB changes, you can print it anyway.

defects in pcb manufacturing

I agree with you. Personally, I would either return them and look for a new supplier or scrap these boards. Unless your customer provided these boards and gave you the go ahead to populate them, they will not be too pleased about the build.

% of wasted components in SMT production

Electronics Forum | Thu Mar 25 14:31:28 EDT 2010 | cguerzoni

Thank you, it seems to be an high scrap %. I think that this % depends on the size of the component (machine loss), on the lot size (new lot set up loss) and on the number of components per reel (new reel set up loss). What do you think abot this?

Does anyone recycle removed PCB tabs?

Electronics Forum | Tue May 18 12:01:29 EDT 2010 | davef

We throw the break-off tabs in the scrap board bin. If your tabs have metal content, metals recycling firms will probably take them. Most tabs have no metal content.

SMT parts loss

My company is trying to develop a system to take into account the SMT parts scrapped by the machine and also the parts lost during loading and unloading feeders. This is causing part shortages for us. I would appreciate if anyone could share how th
