Hi, Have been observed the post reflow inductor skew which is weight of 3.50grams. Can we get any get the exact cause for skew and want to know how to check conveyor vibration.

Magyart is on the right track. Lots of variables. Can you post a photo of the skewed part? But also, is it skewed in the paste before reflow? How many inductors are doing this per board? Lastly, indicate on the photo the direction of travel in the

Molten metal has a high surface tension. If the pads are uneven you can have uneven forces. Decades ago if part were not placed exactly right, they would come out of the oven centered. (or tombstoned)

How big is the board? What is the thickness? How populated is it? Is it warping in the reflow oven? If yes, does the oven have any support? How big is the pad compared to the component footprint? How thick is the stencil? Are the components checked b

hi Team, observed component skew during reflow process. Inductor location. I have attached the image for the same. Please provide your valuable feedback. Attached are the images for the same. Its SAC305 alloy , R0L1 flux chemistry. Regards, Am

if the inductors were your only problem. My mom wouldn't be pleased with the V30200C dual voltage rectifier just below the inductors

We are having a problem with our Heller 1800W oven with certian parts skewing. It seems that some inductors and taller Can caps are shifting around in the oven. It seems it will solder fine and than all of a sudden just be off to one side or the othe
