Component Weights for Double Sided Reflow

Here is a list of the a selected group of components which may be used to calculate the surface tension for parts for use during double sided reflow soldering. Further information is available on reports, Video and CD ROM produced by Bob Willis. A training workshop on double sided reflow is available for in house training on your site.
