Criteria for storing finished SMT assemblies, shelf-life?

Electronics Forum | Thu Sep 11 14:20:07 EDT 2008 | pcbrown57

Is there any criteria or limitations for SMT pcba's? We have boards in stock that we built and a customer wants to know what our procedure is for "storing" these boards which will have a few through-hole modules soldered to them after they get pulled

Non-Waveable SMT Caps

Just a quick thought on solder balls "or beads" caused when using NC paste. I found a spec (12.4.10 in IPC-A-610C) that says solder beads are acceptable if they are entrapped in NC flux residue and can not be dislodged in the normal service environme

Steve, I'm using 5 Sn/1.5 Ag/93.5 Pb Solder wire with a melting point of 300 deg. C to connect my thermocouples on smd components for thermal profiling. I'm using a soldering iron with an adjustable temp. to be able to melt my solder wire. Temp is ab

I'm involved in backplane manufacturing process. There are about 10 electrolitic capacitor assembled in my board.These capacitor are soldered using a selective soldering machine. My problem is that these capacitor will charged up and failed as short

Ni/Sn plated parts

MoonMan, I'll take a crack at the list. Feel free to answer the ones I don't! 1. Solderability is a parameter which indicates how well a component can be soldered. As far as Solder Termination Coatings go, here are some up�s and down�s of a few. Ha

Shelf Life of Components (solderability)

Electronics Forum | Tue Feb 15 21:27:18 EST 2005 | davef

Component shelf life depends on: * Solderability protection type. * Quality of process and materials used in applying solderability protection. * Duration of time from when the solderability protection was applied. * Packaging used in component stor

Neil, IPC 610 has the criteria for solder balls re. quantity and size per sq./in. These are acheivable requirements but no-clean is not necessarily a drop in process. You need to review stencil /pad /component design to ensure that "midship" solde

| What approach do you you use to reducing wave solder dross? What is your experience with Klennox? | Dave F Dave, I use Kleenox on my Air-Vac Volcanic Soldering pots. The stuff works great. It significantly reduces the amount of dross you remove

Wave Solder Troubleshooting chart

Electronics Forum | Thu Jan 31 11:49:21 EST 2002 | MikeF

Does anyone out there have a wave solder troubleshooting chart in electronic form they could e-mail me? I'm about to crank up a wave solder machine here, and the chart I got several jobs ago is missing in action. Also, if anyone remembers using a
