Darn Rob you're brilliant You just solved the dilemma of micro cracks and hot tear in lead free, just add a softer metal like.....and the joints won't crack. You wrote "BTW: Lead is far softer & dissolves far more easily than copper or tin, hence wh

Rob It's documented that lead doesn't leach out of landfills. So, how does Eurolanders health become affected by lead in landfilled electronic products? Isn't the potential for lead poisioning from using leaded glass greater a danger? Given that

try using drill holes.. i have used these in the past, just recently we used them and placed 0.5mm pitch devices fine.,. This should sort you out for this batch but get onto the Customer and tell them you need fiducials for reliability on placement.

I have used tooling holes, connector holes, via holes, and others. As long as the hole is consistent than it should not be a problem. I have never tried a pad for a fiducial before because of the paste being on it and thought it would not work. So ma

We have a C-740. I agree with the second pass statement. Be careful how much you overlap. Also make sure the board is very clean before you coat or its worthless. You will be able to get very accurate results without masking. Let me know if you need

My name is Stephanie Baldwin. I work for USI and have been following this forum. I would suggest that you give both USI and Asymtek the opportunity to coat a sample board for you. You can then compare the two technologies side by side. If possibl

We are deciding on using SN100C on leadfree wave soldering process. As always I am a little worried when materials are not proven or lack of data! I like to see what you guys (not sales people) think about SN100C alloy, specially if you have been usi

I have no experience with soldering to a flash gold finish. We have specified ENIG for a prototype PCB order and the supplier is asking us if they can use flash gold. They are telling us that the two are interchangable which I don't believe. The

I would rather keep my Juki KE-2060. It runs faster, do larger boards, and can place a wider range of components when compared to the Opal. Also, I have trolleys on front and rear, without losing any feeder locations. Why can't you put trolleys on

You could alternatively look at it another way - the customer asked how quick it would be to change over 20-25 feeders. All of the above machines have the capacity to hold at least double this, so the question is can you run the orignal product, w
