1. Each differential pair must pass through a separate hole in all the other layers. 2. Look up the data on the differential outputs and inputs of the chips being used. Those differential signals will be on adjacent pins. If possible, drop the signals directly from their solder pads to the...

Any bolt that clamps a wedge, or passes diagonally through an interface, will have shear forces at some boundaries. That will cause the shank of the bolt to press on the edge of the material. 120 kN is significant, but the method to use will depend on the diameter? of the bolt and the...

What do you mean by "many differential ports in between then"? Please provide a link to a simple circuit example that you want to route.

As a guide, let's say 20 drops per millilitre. 1.9 litre = 1900 millilitres = 38000 drops per hour. That is 10.5 drops per second. I guess your filter has become blocked by something in the water. Are you able to clean the filter? Domestic water pressure is usually about 4 atmospheres. A...

What is the normal flow rate through the filter, when only gravity is present.

1. What material is the lumbar plate made from? 2. Are the holes in the certified upper plate predrilled? You might glue a bevelled washer to the surface before assembly. There are also low temperature solders that would be stronger than glue.

Your question You have been hung up on that question. I believe it is moot, meaningless to this discussion. Why not drill the upper lumbar plate, then provide a shallow counter-bore, in a milling machine set at 10.23°. The bolt head will then seat flat, without any need for bevelled washers...

How will you prevent the beveled D washer from rotating during assembly? The wedge angle of 10.23° will cause the D wedge to move sideways, until the hole in the D wedge contacts the shank of the bolt. What prevents the D wedge from sliding sideway with the bolt head, until the bolt shank is in...

Yes, but the sweet spot for data compression turns out to be a compromise in every dimension. The science of data compression is well understood.

When several hundred pF of contact capacitance, is charged to 18 volts, the current during the initial voltage breakdown of the oil, will be limited by the contact resistance. What is the resistance of the contact, and how does that change with time? Current alone does not cause the damage...

The beetle's circle can be any size, up to a great circle. The sphere will rotate about an axis that passes through the centre of the beetle's circle, and the centre of the sphere.

My prototype model is getting closer, but there are still a few details that need sorting. Why, during conduction, does the contact voltage only fall to 2 volts ? I would expect a metallic contact voltage to be closer to ten millivolts. It could be because there are 40 ohms of series...

As I see it, you are experimenting with EDM die sinking, but you do not want it to actually remove metal, or for the die to sink. There are two parts to each conduction event. Make, then break. The first is the "make", or contact closure. At that moment, the gap capacitance is immediately...

To evaluate ways of preventing arcs, I am attempting a SPICE model of your test rig, but I need more information. 1. What is the diameter of the spherical ball that is one contact? 2. What is the diameter of the disc that makes the other contact? 3. Have you ever estimated or measured the...

It is not resonance. It is the spectrum of the voltage step with higher harmonics removed by the low-pass filter. The highest harmonic present will be the highest one that passes the LP filter. The lowest harmonic missing, will be the one above the LP filter. That one will also have the...
