Perfect, that'll do it! Has 16mm pitch too, thanks!

That is correct. This looks like a board that was printed then wiped but not washed. Solder spheres left out on an unsolderable surface will just sit there like this or coalesce into solder balls. Nothing in the picture indicates an issue with the

Hi everyone, In the assembly of a component of the size of 0201 which Position Accuracy is recommend to use? Stensil thickness? and Solderpaste Type? BR,

In my machines (Yamaha / Assembleon / Philips) there is an option to FIRST rotate the element and then check it with a camera (I do not use it, because it requires an additional better camera) - maybe you will find something like that at home?

Thank you both, it is not the good HLA design and this is why the deflection is needed to sit everything properly in the case. We did ask cust0mer(we are CM) to change it, I am just looking for a standard to support our claim.

I had such problems with SOT-23, how I confused N and S - inversely I entered the number of pins, etc. Check again and again :)

you may also want to try replacing the Motor capacitor. This is often the culprit on those blower motors. I found them on Amazon for $3. much better then $450 for a new motor.

The rotation is a fixed parameter..... and of the 9 parts, randomly it will skew the part, could be one or more... I was thinking maybe the solder paste was too dry and during the LIFT after placement it would blow the part sideways.. Yes I am on a

Do you see foot indentations in the paste? If the part is being blown after placement, you'll see the indentations in the paste. Another random thought; We had worn nozzles and the camera would sometimes see a spot where the paint wore off and read
