As has been mentioned, it's likely that the component is moving in the tape, and flipping over. It is not likely that the pick/place operation is causing this. What I haven't seen mentioned is that there is an acceptability criteria in IPC for inve

Hi, Do you observe any part warping in the corners? Do you X-ray 3D? I really doubt that all joints are fine and the part wouldn't work, but if so, your problem should be part related.If you have a temperature controlled facility I wouldn't even thi

I've put down a SOT223, close enough to your 3pin transistor, in the same situation you have. The large pin was to be soldered on a large exposed ground plane in the corner of a board, over 2"x2" exposed area. We left the paste file as is, so where

I have a customer who is rather inexperienced, and asking us for a solution for them. They have a circuit board that's roughly two inches long by 1/2" wide or so, with component placements on one end of the board. The other end has a trace that I s

I've been struggling trying to get our TP9 machine to place 8-dfn package parts. One of our primary assembly contracts uses a SOIC8 but the pad design accommodates an alternate 8-DFN part and sometimes we have to go to our alternate part due to lead

Hello, we are currently designing one device that needs shielding. Under the shield, there is one BGA chip and 0402 components. Now we have a dilemma whether we should go for a one-part shield or two-part shield. We talked with several EMS companie

Note that the TF2800 features a large 7 panel preheater with an adjustable height component that allows you to adjust the height of the IR preheater to get much closer to the board. This feature multiples the power of the preheater exponentially, so
