I believe on High Temp. Spheres you require paste eutectic 63/37. The solder paste forms an intermettalic bond to the pad and a bond to the surface structure of the high temp sphere. The standard 63/37 alloy spheres will melt during reflow and form t

Isn't that a good reason to use more paste? With just the paste from the balls, do you really get as good a solder joint as with a standard amount of solder paste added? What about voids? Do they go away by not using paste? I am talking about initial

Hi Guys, Maybe you could help me with the above. We are doing IPC Class 3 products and would like to know more about the difference between the 2. We have an Omegameter, do we need an Ionograph too? Which one between the 2 is effective in Ionic Cont

Ionograph measures conductivity while the Omegameter measures resistivity. They both accomplish the same task in terms of ionic contamintation detection, but go about it a different way. One is really no more accurate than another. For more informati

Hi Russ, Thanks for the input. We already check our subcontractor mounting of the connector on the board and it seems that the problem is related to some batch of connectors from their vendor. Anyway, i believe that your suggestions on the agreement

Hey, I'm a student who is trying to etch my own circuit boards (for an art class surprisingly). Does anyone know where I could purchase a copper clad board that uses a transparent laminate? Transparency is sort of important, as this project is more
