If you are 100% inspecting, then all assemblies should be inspected to IPC-A-610 not just the first one. It sure would be nice if assemblies # 2 - 1000 were exactly the same as the first article, but they aren't.

Hi All, In IPC-A-610 there is a definition for what constitutes "Entrapped/encapsulated/attached" on page 5-14 in the note. It says that it means that the ball will not be dislodged in the normal service environment of the product. Jim Jenkins

HI Is there Industry Consensus Document , which is an equivalent of the IPC-A-610D : Acceptability of Electronic Assemblies for "Mechanical Assemblies" ? THANKS ADAM

Brett, I've found out that it is not a defect with respect to Rev. D. You are correct about the thermal expansion but due to the size of the plastic SOIC's and SOT's they have eliminated it as a defect. Thanks, Tim

The water soluble flux residue is staying there because the rinsing temperature it may be too low. The flux needs about 130-140 degrees celcius to become soft. If you are using water soluble flux, as per IPC A 610 standards it needs to be remove comp

I am aware of the IPC A-610 standards on acceptability of electronics, but this place builds our products to an even higher standard. the problem is on the two leading corners of the IC's as they go into the wave.

Toe down solution: * Land pattern design * Solder stencil design * Proper component fabrication Normal gull wing lead solder requirement: Solder must extend to the mid-point of the outside of the lead bend.

For an nate measurement method, look here http://www.ipc.org/4.0_Knowledge/4.1_Standards/test/2.4.22c.pdf For bare boards, look to IPC-6012, par. 3.4.4 For assemblies, look to IPC-A-610

That's one of the old IPC-A-610 revs. The latest, Rev D removed the size allowables and put in a general criteria statement(section 5.2.6.1).

Are you refering to components or assemblies. Assemblies are classified as 1,2 or 3 per IPC-A-610. Components are classified 1 - 6 for moisture sensitivity per J-STD-020
