We are trainee engineers doing research on the vi technology 5k and 5k 3d AOIs, we would like to know the advancements that they have made in the new 3d 5k AOI, and any setbacks if there are any.

Sorry I didn't close this one off last year... We had some failure analysis done on these PCB's ( 3D x-ray,microsectioning,SEM) and the results definitively proved that there was some contamination @ the base of the uvia's that had the voiding. It ap

we have observed a Field claim in ECU where root cause is Lead lift found in one of the IC. What could be the possible reason for lead lift and how to avoid the same in future. QFP is the Type 1.Checked the Part Library(3-D Check Refernece no.-23

Great posting. We're looking at AOI for the first time and are trying to understand the pros/cons of 2D, 2D+, and 3D. M, can you discuss what size parts are too small for the Mirtec MV-3L?

Hello, those plated and solderable via in pads have two critical points: 1. We have discovered that _sometimes_ the plating seems not to be perfect, as extreme voiding is visible in tha bga solder ball 2. The detection of some defects by AXI is limi

Hello, I want to hear some experience about selective soldering for PCB using nozzle plate and screens Do you have solder defects? bridges and insufficient soldering? How do you combat that? and about the screens you have good quality? What is the f

Have you tried cutting the leads shorter (or lift the connector slightly) so that they barely protrude at the other side of the PCB? Just for testing purpose, for mass production you should find a connector with shorter leads then. This should help w

Wondering how many out there have upgraded their AOI systems to 3D technology? For those that have here are some questions I have: 1.) What system were you using previously? 2.) What systems did you evaluate in your process of selecting a new syst
