We've recently identified that one of our wavesolder machines has a high tin content. It should be 63% and is greater than 1% above that. We are adding pure tin to adjust the ratio back to 63%. I'm wondering what defects might be expected as the ti

| Anybody using a Westek Orbital cleaner.I would like to know how well it does the job,We are considering buying a used one. | Larry, If you plan to use wash chemistry, do not buy one. If you plan to use pure water process, full water soluble flux

Before changing solder pastes or jumping through too many hoops, check the melting point of the 100 Sn (pure tin) connection. According to Kester, the melting point of 100Sn solder paste is 232 degrees C. If you do not reach that temperature, you wi

I'm currently trying to get a feel for what oxygen level I will need in my lead-free assembly process. Do I need to go with the pure vaporized liquid nitrogen, or can I get away with one of the other "on-demand" operations? All assistance gratefully

We've been doing it for quite a while on some parts but are noticing that as more manufacturers are going lead free we are starting to see some issues. Particularily with pure tin on nickel. Have found that need to increase oven reflow temp and time

Mr Dengler, I think we've become hardened cynics. We should give Mr Ong a chance. I mean, it's obviously just pure co-incidence that Asahi's assistant sales manager in Malaysia is a Mr Ong, and that the distributor Channel Technologies in Singapo

1 us gallon = 231 in^3 (NIST) 1 inch = 2.54 cm 1 in^3 = 16.38cm^3 16.38 cm^3 X 231 = 3785.41 cm^3 1cm^3 = 1g (pure water) 3785.41 cm^3 = 3785.41g or 3.785.41Kg Do I get credit for showing my work?

Pure ignorance is my answer to that.... You're with a CM, right?? Your idiot customer probably has never stepped foot on a manufacturing floor in his entire gott-damn life, but.... he reads SMT Magazine every month, and probably read some article

�..... their material acts as a barrier to oxidation," is wrong Mr. N. The MS2 material "consumes" oxides therefore removing the oxides from the dross by chemical reaction and releases the pure alloy. It is not a barrier and does not mix into the sol
