We have talked a lot about the defects of putting nitrogen into reflow oven before. Thus, today EBest Circuit (Best Technology) would like to discuss some defects of putting nitrogen in to the reflow oven\u00c2\u00a0with you.<\/p>\n

\u00e2\u02c6\u0161\u00c2\u00a0Nitrogen\u00c2\u00a0is very expensive.<\/p>\n

\u00e2\u02c6\u0161\u00c2\u00a0If the heating effect is better, there will be tombstone effect happening on the resistance and capacitor. This effect is beneficial to most of components, but it will deteriorate the tombstone effect\u00c2\u00a0of the small chip.<\/p>\n

\u00e2\u02c6\u0161\u00c2\u00a0Besides, the nitrogen will also increase the wicking effect of soldering tin, allowing the soldering paste along the fillet weld of the components to climb to a higher place. Maybe it is good for some fillet weld of components, but it is not friendly for some connectors. Because the fillet weld of connectors is the connected to\u00c2\u00a0other components.\u00c2\u00a0It will cause other problems if tin flows into these connections. What\u00e2\u20ac\u2122s more, it will lead to short circuit if the tin climb to a higher place as the fillet welds of connectors are very closely.<\/p>\n
