There is no doubt that we reflowed topside BGA on our wave solder machine. We run our wave pot at 450�F and that�s plenty hot enough to reflow solder on topside SMT components. When the solder balls on the BGA melt, the package is over 200�C, trust

I judge a country's technology level by what they buy and what China is buying are not MSR's and CP-7's. It's MV2's, MV2C's, CP-4's with an MV2F here and there. If that's not behind the curve, I don't know what is. I would say they are 5 years behind

Yeah, but can they place through-hole? We looked at Panasert's Radial a couple years ago. Some big advantages over the Radial Lead 5's that we had at the time, but couldn't deal efficiently with all of our electrolytic cap orientations. We wanted to

Does anyone have a tried-and-true method to account for machine losses of SMT parts? I remember reading an article once that stated that 5% - 10% of components of certain sizes are known to be lost during placement, and I know some CM's overplan by 5

Hi Mike, Here are a couple more good choices: Aqueous Technologies� StencilWash PLUS (unlike �BS�, I will not tout its attributes online and turn this forum into a �BILL�BOARD) Petroferm�s Hydrex WS Contact me offline for specific pro�s and con�s

Hi, If the failure rate is a lot higher than all the other components including ones similar to the 0603's than you won't be making a big deal. It is all relative. My only thought is to run a DOE with 0603's from different manufacturers and see if

The 3S is the low end machine for the 3S 3AV 3Z line. This machine is slow but will run forever. I agree, if there is going to be a problem it will probably be with a feeder if the prevous owner did not maintain them. The factory is in Connecticut

Absolutely, 0402�s are no problem and should not require any special modifications. However, you will find, that not all 0402�s are the same. I have users, who created 5 different GF-packages with different dimensions and light contrast. With small
