Normally, on X-Ray will conduct attribute GR&R which measure capability of operators to judge defect and not on equipment itself.

We still have a lot of parts supplied in stick format for one reason or another and had some old MBF feeders which work great, does anyone know an alternative aside from the vibratory type feeder?

Dear All, Please help to share me Part List for MIRTEC In-Line AOI Machine Model MV-5SE. Thank you for your prompt reply

It doesn't seem clear what you really need. Do you have the default libraries from Mirtec with geometrical shapes/Models?

We don't have. We want to order spare parts, Looking for the Part Number. The machine have damage on the mirror. Please help

A reflow oven with Center rail support can help. If your volumes are too low to justify spending $$ on a proper carrier, titanium stiffeners applied to the PCB before it goes into reflow is a cheap, albeit manual solution.

Are parts always following the same side/direction of tombstone? 1. Run 180 and observe if tombstone moves or remains the same 2. Too much paste under the part - reduce aperture and move it out to the lead. 3. Soak profile for even heat distribution

Thanks for your response. Yes Tombstone is happening in same direction only. We can't rotate every board since the issue is random and the defect rate is around 0.1% Already using high soak profile. Stencil modification in progress.

Yes it's 0201. Homeplate design is not recommended. Simple going to reduce the aperture size. Just planning to reduce it in both the pad cornor. What's your recommendation.

Thanks for the information. Much appreciated. We are using 79um thickness stencil. I will share the inputs to my stencil manufacturer.
