Advertisements are not always 100% accurate on technical issues. You don't want instand static discharge. A wrist strap with no resistor could cause that. Therefore put in a current limiting resistor to make the charge dissipate slowly. Does anyone

I have this NiPdAu small QFN packge sizes less than 2x2. I tried to do solderability Dip And Look test and there's always some units no wet on either ground pad and small I/O. Can someone help to explain why is this so difficult to set on this surfac

Good Morning, I had looked into this several years ago. The Swiffer dust mops use static to capture and contain dust particles. That would make this a huge ESD concern. Electrical SMT equipment is grounded so any charge potential generated would be

Hi, You can go a long to answering that question yourself - what do you need to see? If you are lookig for the normal stuff like bridging, opens and voids you dont need anywhere near 130-160kv. I have just completed the same excercise and we have s

Baking boards to remove moisture takes a lot more energy than you'd think. Following on with this, Chris Hunt from NPL gave a presentation at IPC APEX 2012 about the results of his research ["Impedance Testing for Sensitivity to Delamination in Print

We believe that Dave's analysis above is mostly accurate. Run a board with no components, and check for voids. We'd also like a little more information, though, to clarify. What type of component is experiencing the voiding? You describe the void

I'm looking for a preheater for hand soldering, but haven't used one before so I could use some advice. Does anyone have any preferred styles or brands? Is there anything in particular that I should either look for or should avoid? I've seen prices r

In thinking about troubleshooting tombstoning {TS} defects, seek balance: * Pads the same size * Same amount of paste on each pad * Component placed with the same amount of contact on each pad * Heating the same on each pad, no via connection to a gr
