Hi all! Got a question for you guys:) I'd like to measure if the grayscale of an AXI is stable or not. How shall I do it? Should I do a process capability study or is the X-bar chart-method better? Or is there a third method that I should use? What

I have a job that requires a minimum of 3% lead in all component terminations. Anyone doing DOD out there with the same? How do you get around this with R's and C's especially? I believe we would be OK if the terminations were not pure tin as well bu

In the teach menu of Central controller and under Teach Board Fiducials there should be 6 options. Turn on Global Fiducial Correction by putting a Y in the box. Make sure all others including "Fiducial Data from Autoprogram" have an N in the box. Use

I knew I was doing everything right! I haven't forgot after all. That's exactly what I did, but I still get the error of "Fiducials not taught". I thought that maybe I was forgetting something, but that's not the case :( Maybe I have a bug in my soft

For 15 years I have used a similar method, only I used two bread pans. You can fit alot more solder in them. In one pan I drilled holes very similar to the photo in one pan and used a reclaiming agent such as Kleenox to prep it a bit. Then used the o

I got this thing at a major grocery store called Loblaws. So far I've used it only to test it, and compare it to our $20,000+ solder recovery machine. I just hope my boss doesn't find out about this.

I use this directly in the solder pot inside the wave machine. It is small enough to float at the surface of the solder, yet by loading it it act as a sieve and retains the dross while most of the solder pass trough, allowing me to clean the whole po

The bread pans are stackable, same size at top but smaller at the bottom. I also do this inside the solder wave. Just press the other bread pan on top of the other. It helps to have some guns on you, some little stick boy might not squeeze enough, bu

Hi, I would like to ask if there's a guideline/specification on what is needed to qualify a new SMT automated assembly line? Is there any standards i can refer to? IPC or JEDEC? Is there a reference number for the standards so i can refer to as we

Hi, I think the standard was IPC 6850. But I will recommend to go directly with the sigma test. Place parts with the machine and measure the placement accuracy on another machine. 4-5sigma at 50um should be a good machine. If they have sigma in thei
