I'm not saying that an eraser will necessarily work. What I'm saying is that some erasers may cause more trouble than the eliminate. Look here http://aic.stanford.edu/jaic/articles/jaic28-02-003_2.html We prefer a brand called Ruby Red. The "ole

You definitely need to have live demos of each system, using your specific assembly if you want to compare apples to apples. Each of the AOI OEM's you mentioned have plus amd minus to their unique systems. You will need to evaluate your specific nee

Hello everyone out there in the SMT world. I have a dilema I'm currently running a board that has 3 csp's with a .75 mm. ball pitch and .3mm ball size. And 2 qfp's-160. The stencil is 4 mils thick and I'm using a 63/37 solder paste. My reflow prof

Genny, you may want to look at the brds you will be running and identify the various packages. I do not know what a standard package is. Most chip resistor and capacitors, 0402, 0603, 1206, 1210's are on 8mm feeders, but ic's vary quite a bit. Also r

Hello all, Dave, this is just another example of how your attitude towards others in the forum, outweighs your open mindedness toward their right to participate....It's SMTnet....not DAVENET. I'm not surprised to see you try to quantify the validit

Frank- Your point about the OEM's trying to help a small company with thoughts of bigger and better things in the future is a valid point. I've had that same argument with the OEM's for years but for different reasons. You're still missing the poin

An effective method to compare the two machines is to go to each vendor's nearest demo facility. Go there with PWBs, components and board data. Find out from each vendor what the minimum board data they'll need- like X-Y Centroid, Theta and Reference

Yours is (12 thou x12 thou)/(2x(12 thou +12 thou)x5 thou) = 0.60 * Aspect=W/T for electroformed stencils SB GT 1.1 => Yours is 12 thou/5 thou = 2.40 So, we kind of think of what you�re trying do as maybe printing a 16 pitch QFP, which gives you simi

I am not familiar with your flux but with no-cleans (which I use) the primary cause of icicling is the amount of flux solids left on the board prior to wave and how long the board is in the wave (2.5 to 3.5 seconds should be OK). The amount of flux s
