Guys A very concerned engineer. Just been called over look at some PCB's in our diag area for missing components(0603).Too my shock I have just found that these components can be picked off just using a finger and applying some pressure. And apparen

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

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.

We have the possibility to buy a used Zevatech FS710 pick&place machine with vision. I've read that these machines used to be very well built but I'm wondering if it's capable to place 0603 parts accurately since it lacks a laser-type alignment AFAIK

With what machine? I cannot help until that is disclosed.

Good question :) I'd say with a machine that is available for an average pick and place operator nowadays. Our manufacturer is not fixed yet, that's why I don't have any specific. On a related note I'm wondering whether the machine is so importan

I would expect any half decent machine to place 0603 parts slap bang on target to the typical defined accuracy for such parts on most machines of perhaps ~60 microns or better. Self correction during reflow is IMHO much less pronounced with lead-free

Hi Folks, I'm working on a LED display that is composed of multiple layers. What is interesting for the point of this discussion is the PCB layer and the light deflector layer on top of it. Please take a look at the related pictures at http://plus

hi everyone, new user and noob here. I've spent the last week getting acquainted with my juki 740, being totally new to placement etc it's been fun to learn! I've now gotten to a stage where everything is setup in the machine for my board and is p
