Dave, I have never even seen black pad - even in my subby days. As my wife says whenever I find a good parking spot: "Lucky Darby and his beautiful wife!" This is particularly so if we go to Watto�s - www.sydneypubguide.net/pubs/Watsons_Bay_Hotel_(D

Once a rock star, always a rock star, eh bubba? Ozz don't forget stuff like that. After a half liter of golden merriment, I don't care about how odd the food tastes, I just want to remain agile enough to dodge the sinkholes on the way home.

It depends. What is: * Storage environment and period * Board laminate, epoxy, and copper thickness of PTH * Down stream process * Etc FR4 0.062" thick boards absorb between 0.08 to 0.1%Wt of moisture within a 24 hour period, and 0.2 to 0.23%Wt in

Dave, The parking is difficult but don't believe the reviewer about the getting a table business. I just walk in and my waiter; Luigi the Unbelievable, goes to my regular table and says, "You! Jackman, Gibson anda McPherson - piss off! Mr Jarvis and

"... we've coerced Josh into driving us out to Watson's bay, braving the horrendous parking situation, to visit Doyle's." Good for you, but you could be parking on a sinkhole: http://www.uwsp.edu/geo/faculty/ozsvath/images/winter_park_sinkhole.htm

Believe it! Although it might be necessary in certain rare cases, and as Ray says, as a bandaid, to routinely bake your boards is a mistake. For much more info, search the IPC technet archives over the last few weeks. It was a popular thread

Generic fabs should not require baking. Some special cases like teflon and flex circuits take moisture very well, they often continue to require a trip to the oven. Best wishes, Boca

If these are these bare [or partially assembled] boards, baking probably will not hurt, as long as the bake is not excessive. If these are these assembled boards, baking probably will not accomplish much. What is the source of this water? If it's

What guidelines would you suggest for an assembly house concerning the baking of bare PCB's (assume FR4) and flexes/rigid-flexes before assembly.

We recently came to a cross roads... We have historically baked out ALL of our circuit cards, with a 2 fold purpose 1) to dry the part marking ink, and 2) to eliminate any moisture, which could result in measling further in the process of assembly.
