Hi, What studies? Can you post a link? I am not sure what the difference is between a ceramic BGA that the high temp solder ball is not expected to collapse, and a lead free solder ball that's run through a lead process and also does not collapse b

Good Morning, We are currently using 4 Mirtec machines. We decided on the Mirtec after a side by side evaluation of several tabletop machines. I have to admit that Yestech was not one of them. However, after the evaluation, the Mirtec outperformed t

I have lots of experience with thermosonic gold ball bonding. You can read the literature and you will probably find some papers that say you can do it. I have never been able to do it. We gold ball bond all day long with little problems at all bu

Saw this and thought you may find it amusing. How many forum members does it take to change a light bulb? 1 to change the light bulb and to post that the light bulb has been changed 14 to share similar experiences of changing light bulbs and how t

Well grant just to let you know i feel your pain. I've been wavesoldering with sn100c since January and let's say i'm still learning everyday. Some of the typical causes of bridges are not enough flux when the board hits the solder. Also it can be bo
