Graphics of AMD Processors


There is a small section of pages that provide Images of AMD Processors located on the web site.

All but a few were added to the site back in 2007, with the newest one added today showing a Quad-Core AMD Opteron Processor Die.

The section only brings in a few hits a day so it's really even worth the bandwidth to display the pic files, but I didn't know that when I first loaded them. Two years later and I would not load them now knowing what I know, but now most of them have a page rank so I have little reason to take them down. Plus the best thing about the section is that those page require little or no maintenance.

The pictures are all copyright by AMD but are free to use as long as their conditions are followed.

Here is a list of the other pages in the section:

Designing an Equipment Chassis


Two new pages have been added to the section covering How to Design an Electronic Chassis. The section spans about 44 html pages and attempts to cover all the issues when designing an Electronic Equipment Chassis.

The two new pages cover Wire Selection, and AC Power Modules. However; over the same time there have also been a few pages that were up-dated, including; Connector Dust Caps, Slot By-Pass Cards, Chassis Wire Selection, Slot Filler Panels, and a few others.

At any rate, there is now more information in the section that cover more topics in greater detail. There were other pages updated not listed here, but these were the major updates.

The hits to this section are down a bit over the last year, but only by about 50 visits a week, or 200 a month. It could be the reduction in hits is just due to the time of year..... What ever, any way the up-dates will not be seen by Google for several weeks.

The Bounce rate for this section hovers around 60%.

Derating MIL Spec Resistors


The section on how to derate electronic components has now reached about 120 pages. The main location of Device Derating. A few sections go down two or three levels, but most pages reside just two levels down, with about 95 page just added in three months ago [Transistor Derating Curves].

The new pages cover derating curves for MIL Spec resistors. So far the pages do little more than hold a power derating curve, but with all new page additions that will change in a few days.

MIL SPEC Derating Curves:
MIL-R-30095,
MIL-R-39005,
MIL-R-39007,
MIL-R-39008,
MIL-R-39009,
MIL-R-39015,
MIL-R-39017,
MIL-R-55182,
MIL-R-83401,

All of the new pages are liked off the (now) main Resistor Derating page.
Related pages include;
How to Derate Resistor Networks,
Potentiometer Derating Guidelines,
Wire Wound Potentiometer Derating Curves,

Of course all the pages link to vendors that Manufacture Resistors.
Note; the graphics which depict the curves are not the best quality, but the are readable.

Recommendation on how to Derate a Transistor


Starting with the long list of Transistor Derating Curves, I added in several transistor links to Transistor Derating Guidelines [which is the new page]. Or, recommendations on how to derate a transistor based on a linear equation, with no graphic [Derating Curve].

The new transistor links pick up missing devices in the list, but because I didn't have a derating chart they all point to the new page which provides the derating recommendation for each of the devices. The recommendation for each transistor is how much to decrease power dissipation over increasing temperature, mW/C [and that's all].

Two of the main links off the transistor derating page are NPN Derating Curves, and PNP Derating Curves, but I don't have any plans to add the new links to either of those pages.

Individual transistor pages not yet listed in the blog;
2N3250 Derating Curve.
2N3467 Derating Curve.
2N3485 Derating Curve.
2N3634 Derating Curve.
2N3740 Derating Curve.

2N6764 Derating Curve.
2N6766 Derating Curve.
2N6768 Derating Curve.

Dsub Connector Gender Changer


Added a new page to define Gender Changers. The page is linked off one of the Dictionary of Engineering Terms pages, and off the Manufacturers of D-Sub Connectors page. I'll start to add companies that manufacturer gender changers as I find them.

The graphic is an adapter and not a gender changer. D-sub is short hand for D-Subminiature.

Related pages:
Dsub Shell Dimensions.
Dsub Insert Arrangements.
Mil-C-24308 Connector Manufacturers.
IDC D-sub Shell Dimensions.
Pin/Plug D-sub Shell Dimensions.
9-pin Dsub Insert Arrangement.
25-pin Dsub Insert Arrangements.

An Insert Arrangement is another way to indicate a connector pin out. Insert Arrangements indicate the pin numbering of a connector but does not indicate what signal may be on a pin. The term Signal Assignment is used to define a particular pin with an electrical signal. Signal Assignments for any number of interface buses may be found on the Personal Computer Buses page.

It's a bit early in the day, the virus scanner is running, my server is off-line, and I just can't figure out what to say ~ so I'll have to get back to it and fix it later.
