Thanks Sarason, You are right that chemists and physicists now have some new tricks. Using nano-chemistry the physical properties of the materials change. The melting temperature of our nano-particle silver is below 150C. The insulator is also a nano

So, I haven't used my Quad 4C for a while and when I started everything back up to run a new board it appears that the Quad align is in need of calibration. When I pick up a component and do an LAE measurement on it it shows the part center location

Not exactly SMT but something I recently did that might save you lots of time and money: Complex high $ assy that has 25+ conformal coat keep out areas - most different shapes. All locations are dimensioned on customers' print. We tried a one piec

I have 3 used Quad 4Cs and the nozzle changer on one machine never worked. I decided to troubleshoot it this week. I repaired the changer by changing a defective optical sensor but I still get error 17 when I try a run-step nozzle 1, 2 or 3. Error 17

We all know that whenever possible, we want thermal relief between the barrel/pad and the copper foil to make it easier to properly solder that through hole connector. My question is, assuming there is no connection from the barrel to a copper layer

As you imply in your question, it's counter intuitive that a 2A fuse would blow before an 80mA relay circuit activated in the same circuit. Assuming the 80mA relay circuit is a protection circuit. There's maybe 100 different design goals [ https://bo

In modern education, almost every Electronic Engineer must design a PCB. Once you get to know PCB design tools and functions, then creating a layout will become easier. Today, we find 0.4 mm pitch BGAs in every smartphone, and 0.3 mm ultra-fine pitch
