I have never seen the image quality on the Ersa but the SMT Tools scope we have is definately good enough for spot checks. I have it hooked into my laptop to capture images which works ok.

We have a handheld SMT tools scope. Its fine for spot checking we paid 3 grand for it.

right again grant, consider the fact that if you spend enough time inspecting the soldered boards/pre-oven and check the BGA solder paste pads before, and clean the stencil regularly and check solder paste dryness, check oven profiles then after chec

We have both Ersa scope and X-Ray. Everyone uses the X-ray because it's a quick way to check for shorts, which seems to be the line supervisors only concern when it comes to BGAs. The Ersa is fine, but it's only real use is to examine a couple of r

Get a demonstration, on most packages these systems can see down a row. You don't see solder flux residue with X-Ray. You don't see the intermettalic bond with x-ray. They are some what expensive but together with X-ray you have an excellent quality

Hi, Wow, that's cheap. I did not know they were available that low cost, and we had been quoted much higher for the Ursa scope, so that's why I thought why bother, and lets put it into xray. I bet Superman would have a terrible time working in an S

Hi just to let you know, in case you don't, but an x-ray machine is needed too check the solder balls, once they've been placed. See you later, | | I am very interesting of getting information about the criteria inspection of BGA. Example, what are

Thats because Glenbrook Reps both. The Ersascope was the original and still is the best bang for the buck. How do you know if you have flux residue under the bga without seeing it. Show me an xray system that can see flux residue? Again, this is a PR

We have a version of the SMT Tools scope. We use it hand held style with no stand (much easier). We also find that it is not used very often. XRay and a reliable process are more important to spend the time and money on. This is a good tool to have f

Hi, I have seen demos of these scopes, and don't think they really show you very much. If you profile your board right, and drill up to solder a thermocouple onto the inner balls of the device so you really know your getting a good profile, I don't
