Welcome to the forum. Yes, there is a wide range of equipment types that can be used to measure the function of components after the board is assembled. Look here for test: http://circuitsassembly.com/bguide/

Yes, that I know. But we have been asked to test the component when it comes out of production, before it would be taped. any clues? Regards, Daniel Peeters

I am working on fixturing to keep the pcb/panel from "floating" in the oven. The problem is cold solder/non-wetting on all components. My thoughts lean towards the thin pcb not retaining the "preheat temps" for proper soak/reflow. Any thoughts about

Latex sensitivity is HUge. Try changing to vynal gloves. Also keeping the hands moist is a good idea. ESD Hand cream is an option. Just becareful when using the hand cream as it may transfer to boards, stencils, components......

Assembling boards with 12 pitch are very difficult to control. We like flat surfaces on boards with components below 25 pitch.

We are looking at replacing some solder pots (wave type)for pretinning components. What type are people out there using?

We have done some work with conductive adhesives. The main lesson is: They do not adhere well to solder. * For components, a silver-palladium or gold end termination is recommended. * For substrates, gold over nickel should work well.

We're using 10MPF nozzles to pick 0603 components. I think I have noticed, that it does overlap. Is 08MPF the proper nozzle? These are also the only nozzles that I've had problems with - so this is probably the case.

Thanks for the reply. Like I just posted to the other replier, this is only a problem with 10MPF nozzles picking 0603 components off 8x4mm feeders. Feeders are all taught properly, and pick position is usually off by

Hi Greg, Is anyone logging the errors at QC/touch up stage so they can feed them straight back to SMT and fix them? (i.e. skipped components, poor paste coverage etc) Obviously the faster you spot an error the cheaper it will be for you. Cheers,
