We are having an internal debate here related to minimum Conductor Width. Can you have your QA manager review this and advise. IPC-6012C-2010 3.5.1 Conductor Width and Thickness When not specified on the master drawing the minimum conductor width s

Hi all, our problem we face is the mismatch of conductor width on the delivered PCB and the nominal width given by CAD-data. With CAD we are improving pads and conductors to match the specific needs for soldering and the board houses counteract our i

Wolfgang: "Our desire is to get what we design" ... Wanting to get what you ask for ... ummm sounds like a risky proposition!!! ;-) Two things: 1 Go to the Hadco site and get their "boiler-plate." Use it and some of the Earl Moon specs in the SMTn

Can anyone suggest or identifiy standards which tabulate the following: Conductor width, cross sectional and area conductor thickness for PCB's carrying up to 70 Amps?

I believe that a conductor is a conductor regardless of type, so the surface finish counts. What are the pad spacings that you speak of?

yes, the void should not expose the conductor or bridge the conductor, the coating there should be thick as IPC required but you need minimize the voids and bubbles. ALso for those small chips, a void or bubble on it means possible ECM, normlly shou

Flash gold usually refers to electrolytic gold with a short plating time. In other words gold plating that requires current to plate. If you have bare copper under your soldermask, the gold is probably ENIG. The only other way to have bare copper

tjc, Is this pin connected to a heavy conductor or ground plane? Chris

If the phone jacks have two conductors in them, I would wire them to standard SMEMA connectors so that the upstream side goes to the middle two SMEMA pins and downstream goes to the outermost two pins. If there are 4 conductors in the phone jacks, y
