If the part is kicking up on one side or the other make sure you've done the following: Replaced the inside formers, shoulder screws, shear block and o rings. It sounds like you have the clinch covered. Also check the driver tips. If they are smooth

Is this across different assemblies or components? HAS the machine been calibrated lately? Are you using an adjustable fixture or dedicated tooling plate? Is it a rotating table and are you using it? Was program generated with CAD data or self taught

Hi , Observed component drop during second reflow. Component : Image attached Perimeter : 0.15 to 0.025 cm No of leads : 22 Solder Alloy : Sn63/Pb37 As per component adhesion calculation the component should not fall. ( Excel Attached ) Profile

I would guess then that it is either variation in paste volume (unless you are using an inline SPI), or potentially a damaged chain or sprocket causing a small jump. The second one is easy as you can watch the chain do a full rotation, the first a b

Hi Rob, We used different Reflow Oven and noticed the component drop is less 1 out of 24 components. But not able to analyze, why its falling more in other reflow oven. Our maintenance team is assuring there is no vibration in any of the oven. And

If you go this route vibration will not be your focus. there is something that is called pressure inside an oven. Some ovens have separate parameter to control that. Other will have the blower speed control. You should decrease the pressure(your conv

63/37 goes from solid to liquid. It melts and solidifies at a single temperature. You can add a percentage of silver and get a slight "pasty range" for a couple seconds. I have never seen a temperature change in a profile keep this from happening w

Yes, the barycenter causes drop off since only leads at one side, so a variation of re-flow oven, such as vibration or hot air flow, low re-flow time could help a little. So, how you solve this issue after many months?

We've been doing some testing. It seems that if you move the rail IN to achieve the correct width, the exit is maybe .125" wider than the entrance. If you move it OUT to achieve the width, the exit is .25" more narrow than the entrance. So I believ
