Hi, We are facing the issue with Component orientation(Wrong orientation), during Proto build/NPI time in SMT for 1st board placement. We are not doing 1st board with STICKY board, directly placing the components with Paste board only. Pls suggest, H

Lots of times the suppliers define pin on with a mark on the part molding. Often, they define their approach on their data sheet.

I am a little lost on some of that, but here is what we do. The camera view has the package outline, including an orientation indicator. The operator has the camera step through the program, and checks that the outline and indicator are correct on

Over simplified generic method. Step 1: make a document with every part shape showing zero orientation. Specify CW or CCW. Step 2: Find every step in the process that does not follow the standardisation and adjust as needed. The best I saw this wor

Not these days. Most parts have several molding marks. Or the entire edge has a bevel. Using the ink as polarity is becoming mainstream.

Wouldn't it be nice if all components and packaging were standardized. Some ignaramous that has never done any production work is designing the component and has not a clue what it is like in the real world of manufacturing. Is there an answer to the

I've been saying that for years. Polarity markings shouldn't have to be a guessing game. You really wonder what some of these manufacturers are thinking. It COULD and should be made simpler!
