Yes sorry you are right so you have answered your own question anyway. Dry to start runny at the end

I'm curious how many knobs have left to be turn? :-) Isn't time an issue in a production environment? Vlad

Hi We are designing a new pcb which contains sensitive analogue circuitry, where tiny leakage currents could dramatically affect product performance. Should I build this product Clean or a No-clean chemistry set ? Thanks in advance

Try the "straw test" to test for ionic contamination. For reference, here it is from the fine SMTNet archives: http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=496&#Message3044

i'd like to have design information about how to produce membrane switches using the screenprinting process (making silver traces, buying /placing domes) Who knows where to find information? (we normally only produce the artwork)

How are they being stored and handled? It might be an MSD issue. I think IR reflow would be a worst case scenario.

We have seen this same defect. Led's not blinking during test and some tops popping off. Ended up being an msd problem. most of the lite-on components are msl level 4-6. We now bake and track them no problems seen in a while.

We'd use a hot air gun like a Leister [800-700-6894 http://www.hotairtools.com/products.htm] hot air soldering tool with a nozzle for your connector. We have no relationship, nor receive benefit from the company referenced above.

If the connectors can withstand reflow temperatures you might consider solder preforms. I have personally never tried them. I beleive that you can get them in any configuration desired. Indium and Alpha are some suppliers that I am aware of.

Again, if the connectors can stand reflow temperatures you have the option of intrusive reflow (pin in paste)where you print paste over the holes for one of the connectors. I have did this before on a slightly different type of connector. Works prett
