A binocular microscope gives just a little more info than the video would, as you have views from two slightly different angles. A good stereo microscope gives more resolution or sharpness than video can. You have to take the time to set up the eye

Optical microscope or SEM work fine. You say, "I have found out that the method of measuring intermetallic compound(IMC) formation is quite questionable." What's the issue?

Hello, I did drop testing of some sample boards which had 15mm SAC105&305 BGA's on them. I polished them real nice and looked it under optical microscope for cracks. Was wondering the etching procedure before looking it under SEM. Thanks

Hi, Whenever I'm measuring IMC using the optical microscope, I have to make sure that the images captured are clear. If not, then i will have an issue in differentiating the blurry areas between the IMC and solder(for example). This gives variatio

Hi, I am doing a research on the solder ball joint strength of lead free PBGA package. Coming across a dozen of literatures and journals(and the industry itself), I have found out that the method of measuring intermetallic compound(IMC) formation is

For BGA inspection, it is my feeling that he most effective technique a facility can use is the combination of a transmission x-ray system in conjunction with an endoscope (side viewing optical microscope). In using the transmission x-ray inspection
