That's a good way to do it, but be careful soldering chip capacitors and resistors. Reliability can be a problem when SMD parts are installed this way. They are not meant to be hand-soldered (even to a proper PC board), and it's easy to ruin them by tearing off their end plating. You won't always notice this when it happens.
I've found it's helpful to add a mm or two of bare 24-gauge wire as an expansion joint whenever I mount a chip capacitor between the ground plane and a rigid support like a heavy conductor or pin. -- john, KE5FX > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of [EMAIL PROTECTED] > Sent: Friday, June 06, 2008 8:41 PM > To: [EMAIL PROTECTED]; [email protected] > Subject: [time-nuts] pcb question > > > Hello Norm, > > yes, you are right, that's the way I do it.
