I just got a scope off of Ebay from Precision World. There have been some kinks, but, overall, it was a good experience. The scope I picked up actually zoomed a little too much for our needs (I need to use it for assembly, as well as inspection).

I only build my own products, so it has to meet my needs for QA only. I am doing some 20 mil lead pitch (0.5mm) and will soon be doing a 0.4 mm pitch part. I have more magnification on my microscopes (40X) but almost never need to go that high. If

I have searched through the topics here and none seem to address this specifically. I was wondering if anyone had any links/info directly showing how proper ventilation for fume extraction on a manufacturing floor should be handled. From my research

I have developed an application to help the ease of image set backups for YesTech AOI systems. I'm sure many CM's like to keep their scanned image sets for future reference, and manually moving those files over and over wastes time, and increases th

The CM I work for barely clears 1 million a year. On more than one occasion they had to use their personal funds to make payroll. Our sister company clears over 3million per year. I have been unable to determine what their process engineers are makin

I looked at a number of small bench-top batch ovens and saw two things. First, they got VERY expensive when you got above the very smallest units. Mine will fit an 8 x 12" board. I still have to do one that size and see how uniform the temperature

You will need to develop your reflow profile which includes drilling a hole through the fab and into the ball for accurate temp measure. During profile/process development you will probably want 3D x-ray (consider contracting that out). Once in prod

We had a customer that had 5 BGA's top and 2 bottom and several other assemblies that had 4-7 total BGA's that required WS. Our average build quantity was 2200 boards a month. We used high end Maytag dishwashers and a little Amterge(SP?) Took them t

The tubes don't fit the feeders? I have a Contact Systems vibratory feeder base on my CSM84. It comes with 8 lanes of SOIC only. Well, I use a wider variety of the small chips, from SSOP to wide SO's. The feeder base has some threaded holes in th
