Hello First let me state that I work for an AOI vendor. I will not reference any particular brand of AOI. When considering AOI you need to ask your self several questions. These are in no particular order. What is you product mix (IE High mix low

HOW TO REDUCE MACHINE COMPONENT ATTRITION?

Electronics Forum | Thu Mar 22 12:46:43 EDT 2007 | Hussman

Those Panasonic machines should be able to tell ya pick-up rates form the feeders and shape code errors (components it doesn't recognize). You will probably get a more pick-up errors than anything else. Most of this is due to plastic tape versus pa

Electronics Forum | Mon Mar 26 14:35:44 EDT 2007 | ianchan

Hi all, First off, its great to be back on SMTnet after a long absence; wishing everyone the best in the year 2007 ahead. Question: Is there some sort of industry Standard (Mil?, ANSI?, ISO?) on the Calibration Intervals for mechanical based measu

SMT Line Changeover Time

Yes, pre-loaded feeders is the best way. If you do not have that option as you are high mix or do work for different companies that have many different part numbers, I would guess that your printer will take about 15 minutes to get ready, each HSP f

For a microscope, you want one with the greatest working distance and depth of field you can get. You don't want a lot of magnification, so something like 0.7 - 20 X is good. If you are buying new, have salesmen bring them by and actually try them

Hi Steve-O, Good question(s). This process was set-up by an engineer that had a PhD in statistics, took him a year to develop and then thru it over the wall at us. The biggest problem we saw was SPC to measure solder volume. SPC is good for measu

Reflow oven profiling - frequency ???

Electronics Forum | Wed May 16 18:09:15 EDT 2007 | johnwnz

It always surprises me how many variations there are for profiling and controlling your ovens, and the thing is most of them are fairly valid. Here's yet another option: Your board profile needs to be specific, 2 boards can look identical but have ve

Reflow oven profiling - frequency ???

Electronics Forum | Thu May 17 19:21:39 EDT 2007 | diesel_1t

We are currently using Oven Rider (ECD) to "verify" just the conduct of the peak temperature; we define which product is the higher runner for this line and then with the settings for this product (already profiled with thermal couples attached to th

I am still learning the CSM84, but have gotten one board programmed and working. Now, I'm doing the next board, and need to use the mechanical alignment unit for a 22 x 22 mm TQFP. This chip is too large to clear the jaws on any head. Can the CSM h
