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

I have lots of those parts don't go by the arrow it is a vender marking has nothing to do with the polarity go by the belveled edge you can't go wrong

I'm building a circuit board by hand and can't identify pin 1 on a smt IC. I always determine this by the beveled edge, which this part has, but it also has an arrow on the opposite end, so now I'm unsure which one I should go by...help! Ok, got my

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

We usually program the components in the component database with pin 1 in the lower left corner. Then in the feeder database we set the component orientaion to 270 deg for Tray feeders(turn the tray in the feeder 180 deg) and "tube" feeders. For tape

Hi all, we have two smd line, with 2 topaz X each.Software for optimizing is PPS v.8.0.The problem is that when PPS optimazing the programme, IC, diodes and other polarity components are with wrong orientation.But, I see the orientation onli when str

Thank you for kindness advice. From the result of IC after pass the reflow process. The color of letter will change to similar color of material compound of IC. Then when we inspection by AOI machine, we have many problem about high fault reject rate

Hi Folk, i encounter some components mounted in the different Orientaion (Wrong Orientation). i am puzzle on this.... All these components come in Tape & Reel form. i can only deduce that the Component Wrong Orientation might come from its origina

Here are the basics for theta issues in teaching: 1. CAD part library should match machine part library orientation. 2. If your placement orientation is correct and your feeding orientation(orientation in your feeder) is correct, there should be no

Hi mates, need some help to resolve a thumb-twine situation. As a high-mix, low volume prototype build house, we always conduct a first article inspection (FAI) on every model setup conversion in the SMT production Lot run. we do this FAI by mounti
