AOI, Quality and SPC

Electronics Forum | Mon Mar 03 13:18:02 EST 2003 | msivigny

Hello phil, The use of AOI systems give us the opportunity to auto-collect defect information much the way you're using them now. AOI systems become extremely effective when the collected data is used to perform some positive change into the process.

I would like to enter the discussion by tossing some numbers in. First of all I don�t like the 3 Sigma value. 3 Sigma are 2000 defects per mio. if I remember correctly. This means, if you have 200 components on the board, then every 10 boards have on

Time and temp in lead and lead-free reflow

Electronics Forum | Mon Jul 28 14:30:22 EDT 2008 | grics

Take a look at this. Remember, these are only guidlines and can not replace any paste specs. As Real Chunks said, a profiler will be of HUGE help. We use this to determine what our top side temps are and to see if we have any problems with heat sen

Hello Aldo Can't help you with the virtues of a specific machine but I would suggest that you search this net's industry directory for a number of of other possibilities. Also try Microscan in Washington State. 360/331-8212 John Thorup

solder sphere and weight issues

Electronics Forum | Tue Feb 17 18:17:28 EST 1998 | John Wilson

I am looking for any information or testing data done on the amount of weight that can be held by a bga package based on size of the solder sphere and number of spheres. I am reflowing components with a bga package on the opposite side and looking f

Well said Grant. Sad thing is people fall for glossy brochures, hype, sales pater & numbers etc. and not actual facts. If you want something that will run 24/7 forever you buy a Fuji, it has the proven pedigree. Pete, don't you sell Mydata's?

Easy and inexepnsive SMT machine?

Electronics Forum | Thu Mar 24 09:33:45 EDT 2011 | bobpan

An old quad 2C/4C with a workholder will probably fit all those numbers. 2Ft is pretty long though and that might be a little too long. Machine price range is about right. Programming is pretty easy. Good luck

Component Database and Placement List

For packages, you use packages names.There is only one SOIC8. The other 8-lead devices are there and it is your job to learn their names. For components descision should be made based you your whole(part number)system.

Pick and Place Machine Validation

Of course a new machine out of the box should perform at a realistic Sigma level and it's not unfair to hold a machine manufacturer true to their claims. However, even if a new machine does meet the criteria on day 1, the numbers will be constantly c
