Bob, Ken, I guess I was wrong. I have always been exposed to the term PCB or PCA (Printed Circuit Assembly). I worked with an old engineer a few years back that used PWB to refer to wire wrapped boards, see you do learn something new everyday!!

The amount of spurs and misc noise generated on the PWB will destroy the spectral purity of your system. You need impedance matching circuits and filtering, a PWB will make this extremely difficult. > > Best regards, > Steve "PWB" is just a synonym for "PCB", see http://www.pwbrc.org/faq10.cfm Bob Ammerman RAm Systems -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu --------------------------------- Do you Yahoo!?
