I have a PCMCIA type pcb with an 0603 resistor situated exactly half way along the longest edge the device is 2mm form the edge of the pcb. I have experienced incidences of the device fracturing after breakout (hand operation) (pcbs are routed) Coul

Is the same marking protocol used when identifying 0603, 0402, etc.. components? For instance, would a 27.4K ohm 1% resistor still have four (4) characters to identify if the body color is black? Any feedback is appreciated. Thanks.

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

Typical idents are as follows, but not limited to:- 5% 3 digits, first two are significant figures, third is number of zeros and letter "R" is decimal point. 1% 4 digits, first three are significant figures fourth digit is number of zeros and lette

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
