Has anyone had any success in finding open circuits (i.e. ball present but not soldered to PCB) under collapsible BGA's using an Agilent HP5DX x-ray tester and the BGA2 algorithm? Can anyone recommend an elongated pad design which produces the neces

Hi - I'm looking at 5DX as a method for inspecting BGA joints and would like to hear from anyone with knowledge of this system . Can you tell me how reliable you have found it to be in catching BGA opens ? ...... also any other comments you may have

Hi all, currently, we are seeing BGA problem like solder ball misalign, void, solder short (all under BGA, tested with 5DX), after reflow. We examine the solder ball (raw material of BGA), and see that the ball surface is not smooth, will that affe

Hi, After reflow process we do Automatic inspection and after that direct to 5DX machine to check all the solder joints and we detected it at 5DX inspection. This card havent go to any testing.

The 5DX weighs 8000 pounds. Can your product bear the overhead? We use acoustic microscopy to find BGA opens. We have not had good luck finding opens with other inspection technology. Has Agilent told you that you can detect BGA opens? How is th

It's come time to upgrade our Glenbrook RTX-113 x-ray with something that has a little more "balls", as it were. I've been looking at their 90KV "Jewel Box", figuring that has enough power to keep us in the game for the future. But in speaking with

We are encountering BGA solder open connection. At Functional Test, the board failed. Debug guy diagnosed this BGA open connection (2 locations), by using multimeter. Under 5DX inspection, there is connection. Take the board for localised reflow at

Allow me a contrary viewpoint. I've had these things on my floor and had customers get outsourced evaluations done with them. Most expensive boat anchors I've run across. First the good points: The automated scanning and pattern recognition is go

Looks like an improvement to the spinning stuff, but gads, I wish these people would stop using the term slice. The Teradyne still does not create a slice. It infers things from different sized shadows. It still cannot actually image a slice thoug
