Pin holes in the solder joints on various devices can be an indicator of something amiss with the solder paste itself. Solder paste storage may be a concern. Do you possibly have someone putting paste back in the refrigerator after use? Are you tr

Well it looks like you answered you own question. Why would you send the component out for cross section. Why wouldn't you try a different manufacture, assuming you have already used different date codes on this supplier. Is your company contract man

There is no reason why you can't see these leads clear. Isn't there any way you can play with the lighting? I used to have Siemens machines and I want to say that it was possible. Go on the machine, start editing this shape code and find where you ca

Yeah, your machines are probably even older generation. I can tell you that what you can see is always more clear than what the machine can see(worked with 10 brands and probably 30 models). If you don't have good lighting and camera, some parts jus

I've known Mike Konrad for over 20 years. I like him. He is knowledgeable and generous in the giving of that knowledge. I have no issues with what he said in his vid. We should not get too overly twitchy when someone, sales-type or not, makes an eff

Not to be repetitious, I just don't remember if this has been said or not, I'm old, give me a break. Some people have found that DI water is too thick to properly remove flux residue under low stand-off components.

Hi Fluxgate, Doubt it's the laminate unless you have embedded components. Nickel is ferromagnetic (can be magnetised),so I would expect some level of magnetism in ENIG, but not silver. Are you 100% sure it was immersion silver and not something

what is the best type of fiducial to use when making a PCB? currently the engineer at my job is using a square fiducial on the track layer and it is covered in masking. the camera doesnt pick it up correctly due to the shadow around it. and usually a
