| One of our board fab houses is asking (again) to eliminate the reference designators and polarity markings from boards. This isn't feasible for thru-hole, but what is the industry trend on surface mount assemblies? | Deon Response: Hi Greg, Fr

Anyone have experience in marking boards with data matrix symbols? inline? Laser or ink or label? The objective is serialization and total traceability. I'd really like to speak to you about it!

Could anyone send me equations to calculate controlled impedance of traces on circuit boards. I am most interested in the buried traces in multi layer boards. Thanks, David - piengr@verinet.com

Once the machine has finished placing all th parts is there a way to slow down the speed at which the machine lowers the board back to the conveyors? Or are added board supports the only option?

Hello Everybody Would anyone of you know about the impurities in the Ni/Au pad metallurgy (board side metallurgy) affecting the assembly of the chip on the board. I was told that impurities in gold may lead to void formation in the solder bumps.
