This is a very narrow view you have, X-Ray does not see all the problems that can occur, even with good rework gear or a sound reflow process it is still possible to get soldering defects, how do you know if you have a sound process to begin with if

We looked at some systems but didn't buy any. What we use is a little mirror. I believe Metron makes it. It is a small diamond shaped mirror with beveled sides and a handle. Used with a microscope, you can see a lot. They are around $100.00. Some

Hi, I would check the thing in the following order. 1. Check paste - SPI is the best way. If you don't get the right deposit there is no wonder you have issues. 2. Check reflow profile - tweak it to the point of perfection for the board you have. 3

Do you happen to know where I may find a supplier for the "little mirror"? Google didn't produce relevant search results for Mentor. My method of inspecting possible bridging under a BGA involved a small flashlight placed up against the edge of the

Caltex or Ersa type system is good, Caltex prisms, necessary for looking underneath the BGA can be crashed easily when looking under low profile or Micros. $40-$110 each depending on the availability and who makes 'em. We have 2D and 3D X-ray avai

I am pretty happy with my Ersascope, they have been a little slow with software updates and with software questions that i have had. But my main reason that this has paid for itself is dealing with our non-local contract manufacturers, we have used t

I like you looked all over and was frustrated. The prices that they are asking, you would think that we were back in the 90s when money was all over the place. After looking around I found a BGA-100 from SMT Tools. This system will do everything
