I agree with Ken, the root cause could very well be obvious. However, take a look at the following items, these checks only take a minute to accomplish. 1. If your stepper drivers are the older 5410 Pac Sci modules, check for melted power connectors

Hi Erik, looks like there's not much appetite for this debate on this forum. Possibly because not many use them and aren't in a position to confirm or deny what we know. We use our pumps 6 days a week, 24hrs a day so it's a very dynamic proc

Bob, Great theory if you're selling SN100C, but I have to disagree that an alloy being 4�C off eutectic will cause cracks. When a solder joint exits the solder wave, there is an immediate drop in temperature of 100�C. so being off 4�C is irrelevant.

Q1. What is recommended viscosity standard? A1: There is no standard. ASTM D4040-05 "Standard Test Method for Rheological Properties of Paste Printing and Vehicles by the Falling-Rod Viscometer" is a test method that might work. For more, look her

Yes, I have been using it for 4 years now. We have the 4 axis, 3 head, 2 lines. Inspection station and ir oven. I have to say you will NOT get better support anywhere in this industry than from PVA. Their crew is top notch, always going above and bey

Great work Amol, Please keep us posted about the results of the x sectioning. I personally don't believe that the cracks are due to non-eutectic properties of SAC. Because the alloy is only 4�C off eutectic and when a solder joint exits the solder

The ramp sets the stage for flux activation, and if ramping in a linear fashion, burning off some of the volatiles, but yet preserving the activators. The ramp is also intended to preheat the SMDs to prevent thermal shock. Most solder paste data sh

Good morning, Once again a met annoying solder beading issue while producing board with PLL (leadless, contacts from the bottom side of the package). Board has very high placement density and beads appear near PLL package only. This package is finep
