| Has anyone done head-to-head comparison between these two? If so, what were pro's and cons of each? Which choice, if any, was made? | | We here are looking into implementing an SPC program for Wave Solder. The tool would be used once or twice, by operators, on a daily basis. | A few years ago I did a comparison between the optimizer, the Malcolm Dip Tester, and Glass Plate w/a ruler. The most repeatable and reproducible measurment systems was the Malcolm Dip Tester, followed by a glass plate & ruler, and then the optimizer. I've looked at the Wave Rider becuase I would like to revisit the evaluation, but I am pretty confident that the Dip Tester will still prevail. It's on my agneda to re-evaluate, but it's not at the top of my list.
The Wave Rider comes with some excellent SPC software. But it's fixutre can warp and give false readings. And it just plain old doesn't give accurate reading on the chip wave. I posted a thread about this not too long ago.
I find the Dip Tester to be the most effective tool. It's not heavily advertised, but it's made by Malcolm, the folks who make the solder paste viscometers. If your operators are sophisticated enough to run SPC software, you can just input the readings from the dip tester into SPC. We operate by simple ground rules on cotact & parallelism, and keep the data in a spreadsheet that calculates the CPk's periodically. Email me if you want more info.
