While J-STD-001 specifies an upper limit for acceptance of assembly, we use Resistivity Of Solvent Extract testing as a process control. In truth, this "LT 10.07 �gm/sg in NaCl equivalent" measurement has substantial limitations, not the least of wh

I don't know too much about Fuji, but I'll try myself anyhow. How is the coplanarity unit communicating with the machine controller? Attach a logic analyser, second listener or data analyser and "listen" to the communication with the machine contro

Yes Ion Chromatography can when using a isolated extraction system called the C3 tester. Please email me or call of-line and we can show you what we have done for others to not only idendity the flux cleanliness levels but to qualify the cleaning pr

Best to establish what type of residue is causing this problem and then stamp it out.Speak with SCOPE Labs who offer PCB extraction followed by IR and IC work. So many problems with porous resist at present and NON ionic materials that you really nee

I recently found a company that will take the Gerber data and create full Documentation and machine programs from Gerber. The cost is extremely reasonable, so much so, that I have been having them do all of our work. I cannot even do the work myself

Thanks for the reply, I do know that the HASL finish is "domed " on opposite sides of a QFP site & "smooth" on the other two sides. (ie. Sides 1 & 3 are domed, & sides 2 & 4 are smooth ) depending on the direction the PCB was extracted from sol

Got to agree with John on this, get a stencil cleaning wipe something a little more potent than standard IPA and wipe the surface thoroughly, this should produce a green residue of solder resist. If this does happen then ask your PCB vendor to look a

I think you would be better off designing routing slots into your panel and then use a high speed router to cut out the PCBs. PMJ Automec/Cencorp make such equipment (I used to work for them) but have no affiliation to them anymore. Alot of peopl

Steve--Depends on the number of sku's they're talking about. Consider a small vertical enclosed carousel that will hold the small 6" AKRO (or equal) plastic bins. Push a button & the machine rotates the shelf. Parts are extracted manually. Foot print

Thanks, Chunks. Your first post was correct, it turned out to be the battery. That is that problem solved. Unfortunately I have now got an error message saying Flux Management Failure. Is this just a coincidence? It sounds like something to do with t
