Hi! From your post, it seem like the wave did not really touch the component. You probably need to get the both wave height correct and that it hits the component.It is normal for solder to come through the PCB when using chip wave. The through-hole

Universal use to sell a a device, machine mountable, that could place this connector. I am not sure if they still sell it... It has been 3-4 years since I saw it in action. The upgrade would force the boards stops to remain in the Up position while

What is your squeegee pressure and size. Also does the pad sit on a ground plane, as it looks like it is partially reflowed so surface has gone but not coallesced properly which would indicate it is more a problem with reflow above 217-219C OR obviou

IMHO I would suggest that if you are using flux only during a BGA placement on a small run, that you first tin the pads with your soldering iron, then level the pads back out with wick. Accomplishes two things; adds a little metal to the joint to ma

On first glance it looks like those particular pads were not attached to any traces. If I had to guess I would say that your rework profile got hot enough to melt away the glue holding the pads to the board and they came away with your part when you

While moving to a new location we had to remove the tables from a Philips Comet in order to be able to pass a narrow door. While attempting to calibrate the machine, during Warm-Up a strange error appears, sometimes almost immediately and sometimes a

Many years ago we purchased a IOmega ZIP drive that would connect to the parallel port of the computer. They have a utility called "guest" that we installed on all of the IVC computers. We were then able to connect the drive to the parallel port and

During a service call, We had a FUJI guru tell us that Biral was actually not a great lubricant for LM rails or rust prevention because it thickens and gums up quite quickly, which is true. His recommendation was to use TFL-50 wet lube. We've been u
