Why / What is Electro mechanics?

3

Because.

4

Electro Mechanics: Making sure your Amperes don’t get influenced by Newtons and keep them separated from the rest of the environment.

What’s the electro mechanics of this device?

5

Use of screwdriver advised.Refrain from using hammer pls.

Zooming in: Cabinets

Zooming further: Racks and COTS products

Arriving at PCB level

11

Search for the common parts…..And the differences…

PCB Layer stack-up can get really complex.

12

Getting even more integrated

13Galaxy S6

14

Connecting everything together.

What route does each signal take?

How many cable transitions happen along the way?

Is every cable the same?

What’s left of the signal when it reaches it’s destination?

2: Functional View.

15

What types of electronics do you see in a high tech system?

With what mechanical interface?

Power supplies

16

Main (control)

17

I / O distribution

18

Motion electronics, drivers, Motors

19

Temperature control

20

Sensors / Switches

21

For more info see the sensing presentation.

Processing / Networking

22

Less connections than main control,More performance.

User interfaces

23

3: Connections / Power

> Types of connections

> Applications:> Which:> - Voltage> - Current> - Bandwidth> - No of positions> - pairs, mixed signal, mating, > locking, strain relief, > standards, etc.

Common types: Harting, UMNL, C13, 3-phase

24

D-SUB and small signal

25

Cables

> Types of connections

> Applications:> Which:> - Voltage> - Current> - Voltage-drop> - Labeling> - Bandwidth> - no of conductors/strains> - Safety> - pairs, mixed signal, mating, > locking, strain relief, standards,> etc.

26

Standard COTS cables

> Normal power chord> Ethernet: CAT 5E, CAT 6A, CAT 7> Video: VGA (10 m), DVI-[ID], Display port> USB 2.0 or 3.0? (only up to 5 meters)> Firewire> Serial RS-232

> Coaxial cable with BNC plugs> Flatcables

27

Cable harnesses

28

Standards, there so many to choose from.

29

One currently has a retracted standard,The other isn’t allowed in certain circumstances.

Parts from different manufacturers, don’t always play nice.

Check if everything is according to specification

30

Computer hardware interfaces
