Hello everyone, Can you please recommend a sensor to measure (contactless) level of solder inside of the wave soldering bath? ideally it should be a sensor that can reliably measure distanceto the melted solder and provide distance (as a codified si

Hi Indhu, It could be multiple reasons but probably one root cause. metal nut might require reflow profile change- you need to check it with SMT reflow profiler. the part might be oxidized - you can check solderability or try to solder part using a

Can anybody who has a PPM-retrofitted Quad IV C tell me what they think? I'm still going around in circles trying to decide what to get. I am doing some TSSOP and QFP parts with 0.5 mm lead pitch and 0.65mm, and my current machine isn't accurate en

Hi Phill Thank you, It´s a possibility because that model has many false calls and real defects, but only in one component. A while back we had a similar problem and we changed the component number to a new one, and the cycle time was better, but th

There articles about mixed metallurgy and possible quality issues with this kinds of joints. As it is just repair, I would assume it is a local fix, so you should probably go Pb-free paste. If you want to reflow the board I would re-ball the BGA to m
