| New developments in bulk feeding are making this process of feeding passive components more and more attractive to the PCB manufacturers, for | whom the tape feeding for a long time was the solution. The rapid growth in the number of passive compo

Jax, I appreciate your opinion and no one is right or wrong during such information sharing. Please consider that we all inherit a system and keeping it in the same way is the choice in most cases. Also, "keeping the mm across the house" is not gi

Jeff, I guess my experience in such issues always took me back to the screen printing process and I only want to bring up that portion of the possible causes to this case. When we talk about coplanarity, the component lead coplanarity first comes t

Kris, I gather from your description that the component can not be picked consistently. Meaning that the machine can place the component. How does the component place? Is the placement text book? Take a good look to see if the component isn't being

Hi Richard, I assume that you deal with a component that has 20mil pitch. In this case depending on your pad design you get from 8 to 10mil spacing for your apertures. With a slight reduction of the aperture (10 to 15% for avoiding shorts)and a 6mil

Chris - You are not the first to see this problem. I have seen a similar case on parts from another company. There may be a way to "clean" the parts but I'm not aware of it. Maybe someone else will have an idea. I suggest you ask Motorola h

Dennis, I've seen this before, and in our case we didn't need to seal the edges because there was no concern of shorting or anything in the end product, this is a choice you will have to make, Does your end product have any protrusions or mounting h

Bulk feeding components was and is a great idea, but it seems to stop there. Many P&P equipment vendors have bulk feeding capabilities and most part suppliers sell in bulk cartriges. The problem is in the use. How do you verify resitors that are sitt

Hello Craig Are code dates other than these two coming apart or do they stay together? If other dates stay together you should get together with RFM. Did the process work before and and the defects just start happening? These are pictured on the RFM
