Granite Surface and ESD

Russ if your asking me if covering the surface of the granite defeats the purpose then I'm lost. An ionizer is a very good suggestion but they are not inexpensive. If the table is grounded and the metal bars are on a grounded mat, laminate etc. then

In addition to Daves comments. You might want to look at the layer construction to see if the copper is balanced throughout the board.

Our best suggestion - get the copper balanced and if possible go to higher Tg materials.

Wetting Balance Solderability Equipment

Electronics Forum | Wed Sep 05 16:04:47 EDT 2001 | Kelvin

Dear All, I am looking for a good wetting balance solderability tester. I hope this piece of equipment is maintence free, small dimension and robust. The most important is this equipment should comply with most of the industry test standard, like IP

Warp depends on: * How close the board gets to its Tg during the reflow cycle (the closer you get to the Tg the worse the warp gets) * Amount of copper on each side and the balance between the two * Thickness of the board * Overall length x width * T

They always tell you to calculate ROI, when they want to blow you off. Do a net search using - calculate ROI. Links to three pretty good descriptions on this are: http://www.dmreview.com/editorial/dmreview/print_action.cfm?EdID=2487 http://www.eval

Re: Wave Solder Dwell Time

Electronics Forum | Tue Nov 07 02:50:41 EST 2000 | CharTrain

A solder wetting balance will indicate a time of less than one second for wetting to occur to a solderable surface. The additional time is required to get the metalized surfaces up to soldering temperature. A single sided board has very little mass a
