reflow

(1) The process of heating and melting the solder that has been screen printed onto a printed circuit board in order to bond chips and other components to the board. Surface mount chips (SMT) use the reflow method. Contrast with wave soldering. See also reflowable text.

(2) The changes in appearance, page layout or line breaks of text from an original document to a revised version, due to editing corrections. Reflow requires careful proofreading to be certain no material (including graphics) has been omitted in the updated document.

The thickness of Cu6Sn5 IMC increased with increase in reflow time up to a time of 300s, and the thickness decreased for samples reflowed for 500s.
Abstract: This paper reports the results from percentage-fill measurements of intrusively reflowed Pb-free solder joints, where the same Pb-free alloy has been applied to boards with different finishes.
The test boards had an organic solder preservative (OSP) finish and were reflowed in an air atmosphere.
Higher [DELTA]t assembly designs can be reflowed in air at up to 260[degrees]C.
When the topside is profiled and the bottom side is already profiled, more heat is required so that components on the topside are properly reflowed and to make certain that the desired soldering temperature is achieved for that side of the board.
Several factors can help mitigate the risk of tin whisker growth, such as the use of matte tin, tin alloy, nickel barrier layer and reflowed tin.
In simple terms, a sample of paste is printed on a non-solderable surface--in this case, a ceramic tile--and reflowed.
The samples reflowed in the inert (low oxygen/nitrogen) atmosphere gave improved wetting, which was shown by a circumferential tinning layer around each deposit.
