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

Many board fabs help their customer understand the importance of copper balance. Copper balance * http://www.multi-circuit-boards.eu/en/pcb-design-aid/copper-balance.html * http://electronics.stackexchange.com/questions/85633/what-is-copper-thiev

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.

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

my two cents is double sided lines aren't worth the trouble if you are low volume/high mix. As others have said, balancing this is a nightmare. There are tradeoffs, of course. You will build up WIP, and this is especially problematic if there are MSD

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
