Does anyone know of a good, practical reference for sampling plans and AQL based inspection plans? I'm thinking an AQL for dummies, or the Mechanical Engineering's "Shigley" analog for inspection?
Thanks
Does anyone know of a specification, standard, or industry best practice reference that addresses basic dimensions in first article inspections? I've checked AS9102 and haven't found any guidence.
The question is whether the basic dimension must be referenced in the FAI (First Article...

Does anyone know of a good specification (ASTM, AMS, MIL, etc.) for bright annealing? It is specifically for Iron Nickel alloys, but a generic spec and/or other metal would be acceptable. Thanks!
Does anyone have any data, or even general references on the outgassing of said oxides? There's plenty out there for the stability of iron oxide on iron and CRES, but nothing on the oxides I mention.
I am making a part out of Moly 361. Does anyone know a rough estimate at the minimum cross-section you can machine with this stuff (bought bulk, going to machine it down).
Are there any issues with cracking at thin Xsections (obviously at some point there is)? At what thickness?
No choice...
I am trying to make a very simple system quiet - in essence, a simple thin-cross section beam banging the thin edge into piece of soft rubber. Can't change the rubber.
Looking at natural frequencies, etc. of the beam. Looking at the peaks in the acoustic measurements. Any resources online...
does anyone have references for the long term reliability of Au-Au wirebonds? They are clearly accepted in industry as the most reliable system, and don't suffer any of the intermetallic issues of the Au-Al system, but I haven't found much literature out there. I'm not concerned with the...
Does anyone have a reference for diffusion of Manganese in Gold (diffusion constant and activation energy is what I'm looking for specifically, but i'll take whatever is out there)?
I'm looking for the same for Au in Nickel. Thanks.
I am looking high and low through IPC, ANSI, and every spec organization I can use to find a good reference for metallization quality standards. My eyes are going buggy. Specifically, I am interested in specifying the plating void criteria (prior to solder) for metallized areas that will have...
I'm looking on some data for thermal contact resistance of gold to aluminum. Specifics, although not particularly relevant, since I'm not doing lab-grade research here -- just more of an estimation:
thick film "soft" gold ~32 uin RMS on a ceramic substrate
machined 6061-T6 aluminum, no...
Anyone familiar with using Titanium screws or Aluminum screws in a military environment. Corrosion is not a big concern (should be in a sealed environement). They are not being used for major structural means -- just to fasten some electronics boards together w/ standoffs into an aluminum...
I am looking for a good design reference for metric stuff (socket head cap screws, button head screws) without paying $150 / screw spec. I don't need the detailed specs yet, just a reference to even see what will fit in my 3D models. Once I settle on a design, I don't mind paying the money for...
I am looking for a good (cheap/dirty) way to dampen electronics boards in a very space limited enclosure under high shock. I was hoping to find a COTS foam tape (~.15 and ~.25 thk) that I could stick between the boards in certain places to prevent high frequency vibration.
Anyone know of a...

I'm looking for a low profile way to fasten a nominally square electronics board to a mating hunk of metal. The smaller the better. It also has to be a positive pressure feature, since the system will be in a high shock and vib environment. I'd like to keep it to COTS stuff if possible...
