Never heard of billboarding. Could you please explain what that means according to 0603�s. Headshaking Wolfgang

I have some billboarding 0603's and I'm trying to find potential causes. Small boards 2"X 3". .060"thk Hasl surface.

Wolfgang, Billboarding is kinda like a tombstone. The part is just sitting on it's side instead of on it's end. There should be plenty of info on this in the archives under billboard and tombstone. Most likely cause is off center placement and ov

Yep i agree most likely misplacment or reflow, maybe check your air flow around the liquidous zones(if convection oven) probably too low.

Check the pick position of the component from the feeder, the feeder advancement speed, the type of feeder tape, static interference, and the cavity tolerance or slope of the carrier tape.

Hi, Have you checked your placements pre-reflow? The most typical cause of a billboard unlike tombstoning is a pick and place issue. Billboarding will usually happen with ( profile/bad pad layout and the most common just poor center placement. I'v

Hi, My question is how close can you place smd 0603 chip resistors to each other with having an assembly problem? I know the pick and place machines don't need a lot of clearance, Iam more concerned about the court yard area around the component to

Is the industry really moving toward unmarked chip resistors? I've been seeing a lot of unmarked 0603 resistors lately, and when I check the data sheets, all their photos are of marked parts, and they don't say anything about it.

Yageo announced their decision to stop marking SMD resistors back in 2013, and since then we have started to see 0603's that aren't marked, but larger sizes - so far - are still showing a value. 0402's have never been marked, and I doubt they ever w
