Dear all : We are suffering a severe curvature in our boards when coming out of the wave solder m/c. An Engineer suggested to enter them again for a second pass in the m/c expecting board were thermally mistreated just after the W.S. Can this real

Mesh opening size may be a factor in whether or not the paste will pass but only in very fine line deposition. Generally speaking, the printed line width and deposition thickness determine what mesh to use. The paste supplier will be able to tell you

Hi, If you're thinking of a new machine and the volumes are not very high, I think Assembleon's OPAL XII should be the best fit. It can handle VERY LARGE boards upto 25.5" x 17" (with single pass) and 25.5" x 33.5" (with double pass). However for th

Hi guys! We just had our SnPb wave solder samples tested. However, the papers just gave us the contents and the percentage of each contents found with the sample. Does anybody know the passing range and/or paramters of the following elements: Pb, Cu,
