I agree with your assessment of the two pins with irregular solder. The head-in-pillow or broken joint are both probable events for your defect. At this point in the process it will probably be difficult to pinpoint the exact cause. If it was a broke

Even when you run a board several times, the machine may not make the same travel path every time. This in itself does not create a problem, but the vacuum on the nozzles could be different, dependent on the configuration of components on the heads.

There is no solution in above case, this is caused by the PCB design. There are no thermals on the pads connected to the copper poured area. So the other pad reflow first and lift the component.

Anyone who knows how to prevent such flaw? Tombstones are those lifted components from one sides. This results in costly and time-consuming amounts of touch-up and re-work after the assembly is completed. For the customers, this extra work translate

Hi Mike, I haven't tried the 0201s with a Hyrda, but after seeing 20 reviews of your message without a response, I'll try and share my experience with 0402s on a non-Hydra machine. The 0402s are slow, but I managed to get some speed by maxing out

We have experienced poor adhesion of acrylic conformal coating to plastic bodied IC�s. The observed symptoms of this are a blistering or lifting of the coating at the surface of the component, although peel testing has revealed that this is not alwa
