I am pretty sure, you are looking into the wrong spot. Your paste is too much, or your part has very inconsistent narrow leads(that includes wrong pad design as well.)

Hi Guys.. Does anybody had experienced with designing the stencil for Right Angle LED without any dewetting problem on the LED termination? Currently our stencil opening is 1:1 and we still got so high reject due to this problem. Pls Advise, thanks

I�d appreciate assistance in trying to resolve a placement/soldering problem. My company has designed a board which uses a large number of 0402 LED�s that are .028� high. The LED�s need to be soldered so that they point straight up and are not til

We make PCB assemblies for an RGB arc that is made up of multiple curved PCB's that have connectors on the ends to plug together. I think the end the radius of the arc is 2 feet. Jerry

On the board, LTST-S320KGKT (LED) was supposed to be placed as shown in the figure. The pads and silkscreen with legend were also made as shown in the figure. But after the part was placed on the board, I realized that the sizes recommended by the LE
