Sounds like an ideal method for damaging fragile solder connections, eh? Is your customer paying extra for this 'inspection'?

Don't detach the bead and don't twist the wires! The bead should be what makes contact with where you want to measure temperature. Tape is not the ideal method to attached thermocouples for reflow soldering but is OK when using for wave solder prehea

Okay... to follow-up on my scenario. Would it be cheaper to get a resealer with dessicants and humidity indicators or a baking oven, or both. Is there a moisture controlled storage cabinet (ideally 3'x6'x1' or in that vicinity)? Would be interested

This is what I use: http://www.omega.com/Temperature/pdf/5TC.pdf or http://www.omega.com/Temperature/pdf/5LSC_5SRTC.pdf The 36 and 40 AWG sizes are ideal (TT insulation.) $430 for 9 thermocouples seems real high.

I'm looking for some data to support my argument that HASL boards are not the most ideal boards for manufacturing involving BGA's and 0402's. I'm sure one of you SMT Gurus out there can point me in the right direction! Thank you in advance!

I agree with the stand alone option. That way you can sample PCB's from different stages ( print, placement post reflow) In a controled process, after reflow inspection would be ideal.

I ran into this yesterday. Seems some designer decided to not solder resist the via's on the solder side. Then the assembly went over the wave solder in a universal fixture. Not an ideal situation.

This is as much a question of the forum as it is a response, but a small batch oven with programmable profiling, quick response and forced cooling sounds ideal. My question is do they even exist, and if so are they cost prohibitive to the market tha

Chunks, Have you been off on a Yogic enlightenment course, or does the filter need changing on the purex unit nearest your desk? "Idealism increases in direct proportion to one's distance from the problem."

Ball SACs are not hard to over come. Most people solder these devices well using a straight ramp with a slight knee right before liquidous. Ramp-soak-and spike would not an ideal way to reflow.....
