Matt, Had a similar problem with HASL that wasn't fluxed properly during fab. The appearance of the HASL looked dull and/or mottled (sp?). Solder was curled under on the edges where it should have been smoothly joined to the pad. Almost like a pu

I agree with DaveF's recommendation to see Foresight's website (www.residues.com). They have excellent Case Studies on display (for free). There is a good case study which references the results you can expect using a ROSE tester vs other control met

We are using the Red-E Sets on our DEK Infinities and they are working fairly well. There are some issues but the setup time beat the Form Flex and was more reliable than the Autoflex in our machines. We looked at Grid Lock. This seemed to solve all

I would get a demo set of the form flex (they will probably give you it for at least a few weeks hopefully a month) and check it out. They could be much more reliable than when I tested them. I would definately take a working form-flex over a working

I'm glad I dropped in here. I am about to buy some tooling for a Fuji GP-641E. I have been told to get the Red-E-Set, but from this discussion I'm not sure if that's a good idea. The local dealer wants US$1000 each for the 24" segments, we would pro

I have worked w/ the GSI SVS 8200's. They seem to do a pretty decent job, but, they are a "bottleneck" on my lines. I hope you are using good screen printers, because they WILL find the slightest "defect". About 75% of our failures are actually fa

Dynaperts are good machines. If yours works, it should more than cover your costs. Alternatives are: * There is a large number of used assembly equipment resellers out there. Some of them buy banners here on SMTnet. You can find lists of them by

On contaminated assemblies: While you isolated part of your dendritic growth to contaminated boards, could it be that you have a similar problem with other components, rather than your flux? Is this flux new? Have you had similar problems with thi

Hi there - unfortunately, there are no good cleanliness specs available mainly because clealiness requirements are case sensitive - you should talk to Terry Munson at 765-457-8095 - he can definitely give you advice on Ion Chromatography, SIR, ROSE t

Check with Dupont's web site. They have a wealth of information on the various polyimide products they manufacture. I was quite surrised at the differences in materials and in particular the dimensional stability and hydroscopy. Good stuff mayna
