Nitrogen in IR Reflow Soldering

Effect of Reflow Profile on Intermetallic Compound Formation

Reflow soldering in a nitrogen atmosphere is a common process consideration in surface mount technology assembly. This is because the use of nitrogen in reflow equipment may benefit the process as well as the quality of the end product, where it can increase the reliability of the solder joint. So far, many papers have reported effects of cooling speed, type of solder pastes and solder fluxes o...

Practical Considerations For Attaching Surface-mount Components

What automated soldering methods can be considered for Mini-Circuits surface-mount components? There are two basic methods: reflow and wave soldering. Generally, reflow soldering can be done when (l) there are only surface mount components, or (2) these are present together with through-hole components and the latter will be soldered in a separate (wave soldering) step. The surface-mount compon...

No-Clean Reflow Process Implementation

ne of the corporate goals at AT&T is to eliminate chloroflurocarbons (CFCs) from its manufacturing operations by the end of 1994. Many alternatives have been implemented to meet this objective, including noclean wave soldering using low-solids flux, aqueous cleaning of water-soluble flux, aqueous cleaning with saponifiers and semiaqueous (terpene) cleaning. Part 1 of this article describes the ...
