We use our Yestech and Mirtec to do that same thing. Verify the lead is in the hole and check the solder fillet. This is done as part of our normal solder inspection for mixed technology high runners. You may not be able to put together a program

Our model of machine does not do "blob analysis" so I'm not sure what you mean by that. "Pattern matching" will only pass if I set the pass percentage down to about 45% and I don't feel comfortable with that. When using a solder inspection everything

Shawn, Wow. This is a tough one. The part is a 1 pc where I'm used to seeing a 2pc. In our case, we have several assemblies using a 2 pc system (see Laird BMI-S-207-C and BMI-S-207-F). The "C" and the "F" stand for Cover and Fence. The Fence is

I have a 208 pin QFP that due to manufacture obsolescence I have to get them form the broker market. I've had several issues with the parts including; bent leads, leads that don't take solder very well, co-planarity problems, and DOA fallout after a

Let me start off by saying that although we pot a decent variety of products, we have never been asked to do something like this, so this is not based on personal experience. This is just my gut talking here. I suppose you could use some sort of ca

With the Pb-Free BGA on there, you'll want to use pb-free solder paste for assembly. The logical course of action would be to use Pb-free solder paste for the entire assembly, and to reflow at the temperatures necessary for the BGA and Pb-free paste

Yes, car rims (and brass tubas)! You finally helped me get to the bottom of this expensive issue. We fired the culprit. It's the same guy that was using the ultrasonic stencil washer to clean car parts on night shift. It might be snake oil, I don

Why isn't the data that is collected being used? Either use the data or stop taking it. Without AOI to improve your process you need to do this: 1. Collect data on all defects found by your inspection department and have it in a form such as a sprea

Keep in mind that you may need to assure that there are no pure tin finishes remaining on your parts. A general idea is that parts with pure tin (RoHs) finish will need to be plated with tin-lead solder to avoid the possibility of tin whiskers formi
