Jason, If IPC has no bearing on the state of the RoHS, I hope that one day some organization will. Here's a thread from another forum that hopefully makes the RoHS supporters re-think. http://www.smtinfo.net/forum/index.php?showtopic=84

Voltage does not flow. Current flows as a result of a change in voltage. Current capacity of traces * Graph is IPC-2221 paragraph 6.2, Figure 6.4 * http://www.geocities.com/CapeCanaveral/Lab/9643/TraceWidth.htm

Many companies use IPC-CC-830B as a replacement for the deactivated MIL-I-46058 conformal coating standard.

If floor space is not too big a concern, don't forget about IPC9850 to really measure the true speed ratings of each PP machine.

Is this the same IPC-9850 standard that requires users to purchase a $26,000 glass component/board kit? That's nuts.

Most pick-&-place machine companies will give you their data from the IPC-9850 results in terms of placements per hour. I see it on many machine specification sheets these days.

Aside from a visual first article to IPC 610, what inspection criteria do people put in place post wave solder (pre clean)? Thank you

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.

IPC-2222 - Sectional Design Standard For Printed Board For Organic Printed Boards, Table 9-3 � Plated Through Hole Diameter To Lead Diameter Relationships will give you the standard information you require.
