Our present lab went "South." We need a lab that can do temperature/humidity conditioing, convection oven baking, C-Mode Scanning Acoustical Microscopic package inspection and "No-Pb" reflow simulation. We are evaluating a low temperature package dry

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
