Press-on Connector Covers

I had a few yet to be used connector cover graphics so I added a new page to hold them.
The new page is called Press-on Connector Covers. The original page covered all styles of Protective Dust Covers. Both pages are part of the section on How to design Equipment Chassis.
This will be one of those page that will never see many page views. Although the page does not have a lot of text, the text it does have is a copy of the original page.

Wire size and Resistance

I started a new page yesterday in regards to Wire Gauge vs Resistance.
As I get started on it the page my offer a faster alternative to deciphering the larger Copper Wire Gauge table.

Other then that I don't have much to say. I'll keep working on it......

Via Stubs

Started a new page to cover Via Stubs in Printed Circuit Boards [PCB]. The page is linked off the definition of Via Stub, as a read more kind of thing.

A Via stub is a via that runs past the layer a trace is on. For example a trace on the layer 3 needs to connect to a trace on layer five but the via runs from the top layer to the bottom layer, the stub is the portion of the via that extends past layer 5 running to the bottom layer. A via stub is the same thing as a transmission line stub.

A related page covers How to Terminate a Trace.

Anyway, it's a start to cover the topic, I'll keep working on it for another few hours.

Definition of Printed Wiring Board Terms

I went ahead and divided up one of the last pages of PWB Terms that was just too long. The new page covers PCB Terms from 'Gr' to 'O'. While the original page now covers terms 'A' to 'Ge' [listed first].
So the section also covers PWB Definitions 'P' to 'R', and 'S' terms starting with Secondary Side, and 'T' to 'Z' terms starting with Tented Via. There is also a side page that covers PWB Classifications, which has received almost no page views.
All the pages are now pointing to the new page addition, but the new page still needs a little work with the side bar which is a bit to long. From the counter stats it appears I started this 6 page section on PWB definitions on July 25th, and have slowing been adding new terms and PCB pics. However; there appears to be many days the section either receives no visits or just a few page views.

I should be adding another page maybe tonight covering High speed vias. Maybe I should write it before I pick a name.

Capacitor Networks

I added a new page the other day on Capacitor Networks, or capacitor arrays and forgot to blog about it. The new page is linked off the Capacitor Dictionary, or Capacitor Array Definition.

The page shows three different Single In-Line Packages, two capacitor networks and one capacitor array, with standard capacitor values. A related page holds the definition of Capacitor Network.

Which for some reason does not have a page rank, not sure why. Looks like this section has 15 different pages of capacitor terms.

Comment; Ya know there is a bad side to capacitor arrays in a single package, like a SIP. Normally you want the capacitor placed as close to some component as possible. Placement becomes a bit hard once all the individual devices are placed or hard-wired within the same component. You can get one capacitor near the area you want it but the others are wired as they reside in the SIP package.
