I got here before the experts did. Underwriters Laboratory Incorporated is an organization located in the United States and is purely concerned with product safety performance. UL operates laboratories for the investigation of materials, products,

You probably pay the same as me. Ours is just fresher. ;) So fresh, in fact, that sometimes we can smell the brewery, when it's breezin' southerly. Not particularly appetizing, actually, although not as bad as the Stock Pot soup factory. City-wid

Hi Kevin, the profile doesn't actually qualify something as lead free or not it's purely the Pb content of the assembly that does this. Currently the understanding of the limitations of the lead in the jont is 0.1% by weight or less. So as long as y

adlsmt You have stated that an OEM will not sell you a part for a used machine that was built by the OEM and is still supported per the OEM�s standard part policy unless you buy a contract. I will admit I find that hard to believe. Unless you are

Why not.. You are always welcome. Firstly what I feel multicamera system (Top and Angled) AOI is always better than single Top camera system in terms of defect coverage. Secondly read On the fly inspection is much better than STOP and Go techniques.

From what I have seen some component terminal finished have a problem due to storage also. I have seen pure nickel finished turn black. I have seen silver barring finished have problems too. It all depends on how you chose your process, PCB plating,

I hate to sound like a broken record but the industry has been placing lead free through-hole parts forever. Now all of a sudden its a problem??? Gold finish, silver, silver paladium, alloy 42, even pure copper. Reliability will be a function of t

Hello Greg, I agree with you that the article in SMT Magazine should be studied very carefully as it contains many errors in respect to SN100C. The testing performed was a DOE and was not an optimized run. There is also a statement on dross generatio

Why don't you guys look at the "WORLD LEADERS IN SOLDER RECOVERY". EVS International make the EVS 3000 and EVS 6000 Solder Recovery Systems. Many other companies have tried to come up with different ways of recovering solder but the EVS is the best
