Well, I�ve never encountered any problems with it. If you use paste in the specified window according time and environment there should be no problem. If you try to measure this force you would IMO check out if you yourself did not treat the paste as

We used Promosol Sn96.5/Ag 3.5 during our initial qualification for similar application. We could not achieve a shiny solder joint. Our changes to Sn95.5/Ag 4.5 does not improve the look. In order to confirm the reliability of the joint, I suggest yo

Since your problem has been posted quite some time ago I am eager to know, if you have got any clue. One of my customers recently claimed our 313-PBGA causing problems, as one of its balls (randomly) is almost dewetting. So no evidence is found by x-

We are a contract manufacturer and we do business with a big company. There is a mistake in the design of the PCBs they are supplying: the pads are too long (under the component) and sometimes we get short circuit we cannot see. Changing the design w

Hi, Ok, and I will check that out. We do treat the solder paste as a perishable now, and after each day's run, we throw used paste out. That's helped a lot overall. I agree on the hot dog rollers. I have always thought those things were a cool, but

I agree that Moonman is a pretentious wannabe in the industry. His site has no relevant information, the only humur in there is a picture of his fat finger pushing a button. Myself and my collegues here thought of making a "fake" consulting company

Hi, One of our suppliers suggested you could use the microwave to warm up the solder paste if you really needed to, and it did work for a full tube, but when I tried a half used tube, I thought I had invented a weapon of mass destruction. It was sca

As we are a low volume shop, the extra handling is not too much of a concern. My biggest concern is if the flux sitting on teh board for a long time (few hours) is going to cause any problems in solderability. My thought is that it should not as it

I had horrible experiences with a certain brand on multiple types of BGA's (I choose not to mention the brand). The paste was nice and active, but almost to a fault when it came to BGA's. Finally, I arrived at a profile with a more agressive ramp u
