chrissie, at my last place of employment the reason they did it was so they could print the last of a lot, then change over the printer and start printing up for the next lot and have some ready to go when they finished changing over the chip shooter

To do a profile at most companies, if you don't have a scrap board handy, you'll use the already-soldered board that's already been through ONE reflow cycle. You spend time attaching T/C's with the aluminum tape - after all, the prep-work is half th

Hi, Yes, the Q axis rotates easily both manually and with the use of the inching keys. What's interesting is that the hesitation occurs even if the Q-axis is pre-rotated before picking up the part so I don't think the Q-axis is actually being calle

Hi Bert , I dont know much about IP , since I partnered our Fuji CP 6 with Siemens .At any rate, can you check your flat ribbon cable of your Ip's Head. I assume there one wire that is nearly breaking. During movement, head servo controller experie

Hi Chrissie, BGA Rework from one CM's view: 10% process problem (printing, reflow, voids, etc) 10% component failure (no other problem found) 80% "The board does not work therefore it must be the BGA" This, of course, is exaggerated. My point bein

I agree with CL. Most people blame the BGA cause it's a mystery chip to most people. Only after replacing the BGA several times do most people look else where. 90% of the time it's something else. Doing all your engineering work up front is the

We picture that the 'ridges' are partitions that run parallel in the box and are spaced wide enough to: * Hold the boards vertical by sliding them into the ridges * Prevent the boards from bumping together Can you rearrange these partitions to form

"Unfortunately breakaways aren't an option - they are large boards and we already have problems hand placing components and probing them." Not sure what this means in this context....if you frame the perimeter with a 1/2" border on a V-score, how do

Chrissie also says, "Before anyone suggests it - redesign of the boards is not an option!!", so I'm assuming that re-design means panelization too. She's probably sitting on thousands of these unpanelized PCB's in stock. Now, for the future, as Ste

If the Bliss carts would help you can cut some money out by buying aluminum bakers carts at your local restaurant supply house for less than $100/each and then buy ESD trays from another local source (Bliss is rather pricy). You will have to hang a c
