Hi has anyone noticed any issues with reduced component lead diameters on through hole resistors? All the volume manufacturers have or are in the process of reducing the lead diameters from 0.6mm to 0.4mm due to the huge increase in copper prices o

Thanks for the reply. We have carefully inspected the part and solder joint after depaneling and all looks good. What is weird is if you remove the part from the board and check continuity with a meter you have a dead short. If you put on a new part

I would like to take an informal poll on 0201 feeders. I am currently using Tyco machines and 0201 feeders for these machines have become impossible to find. I am hoping to get some feedback on other manufacturers feeders and try to modify them to fi

We are looking for a tool to perform BOM comparisons. I know that Aegis and Valor provide this capability within their CAM offerings. I'm trying to find something that I don't need infrastructure to utilize and won't break the bank. Anyone who use

The kester better known as KY'd Sn/Cu has more copper intermetallic growth over time, dissolves copper from the board faster so repairing and touchup can damage board. Bridges more than SN100c. Does not thermal cycle well. Has shrink cracks that can

Thanks for the replies, fellas. Pretty much what I'd thought too, but you know, when it just doesn' LOOK right.... "the .010" spacing is a violation of IPC 782" Not my problem. ;) You should see the decal they're using for the Xilinx PQFP 208. No

Good for you smtspecialist and your clean oven. It's always better to be too picky, cause once the goo starts dripping, they'll only blame it on your paste. Mistress? No, gotta keep gender out of the work place. How about "Connoisseur Chunks"? S

I don't think so. But I want to point out the amount of lead needed to contaminate a joint is microscopic. You won't have lead vapour in your oven and with a clean oven there probably isn't any other way for even a microscopic amount of lead to con

I think Mr Guru likes to smoke his joints leaded. Seriously, Soltec offers 'leadfree upgrade kits'. You should be fine with 8 zones, but if you don't have bottom heating, you might want to consider inserting some in your reflow (peak) zones. Give
