Yes, there is a limitation with Transmission X-ray on double-side SMT boards, ie.: back-to-back solder joints, components on bttom side over a solder joint.

Cheers Rob, I thought that I wasn't far from the true answer....I figured that if we were to use a "first piece assembly " quote to get a first off through smt production, This would include start to finish process....e.g Programming to first board

For repeated model runs, we go ahead with the SMT run, whilst the QA does the FA inspection. Limit FA timing to 2h or less...(simple boards yield faster time cycles). For new model runs, yep, we wait for QA to confirm the FA inspection, only with QA

It sounds as if you have your AOI set up off-line, and you're "AOIing" a sampling of the PCBs produced. If that’s the case, then the responsibility of who drives the inspection really depends on how you configure it. If it's based on the number of P

Since we are on the topic, What we do over here, is to get SMT Technical to machine pick&place "sample component layouts" onto double-sided tape, which in turn is placed onto an actual PCB... QA will take that double-sided tape sample, and using an

I would look at the SMT Tools BGA-100 scope this is by far the most cost effective tool for the money. We use it in conjunction with our Glenbrook X-ray and get great results. Gary

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.

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

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
