What is the difference between a Printed Assembly and an Electronic Module?

Question

Electronics

Friends. Confused by terminology and definitions.

There is a term Printed knot , which is defined as:

• IEC 60194-2:2019 printed board assembly: An assembly that uses a printed circuit board to install components and provide interconnections.
  
• GOST R 53386-2009 printed circuit assembly: A printed circuit board with electrical and mechanical elements and (or) other printed circuit boards connected to it in accordance with the drawing.
  

And there is the term Electronic module , which is defined as:

• IEC 60194-2:2019 electronic module (packaging and interconnecting assembly): Term for an assembly that has components mounted on one or both sides of the module and an interconnection structure.
  
• GOST R 52003-2003 electronic module; EM: Structurally and functionally complete radio-electronic device or radio-electronic functional unit, made (made) in a modular or trunk-modular design, ensuring structural, electrical, informational compatibility and interchangeability.
  

In fact, different words describe the same thing. Something made from a circuit board, electronic components and a heatsink, ready to be installed in a device (for example, to replace the same, but failed).

Is the motherboard in a laptop that is ordered at a service center for replacement a Printed Assembly or an Electronic Module?

What about the switching power supply in your TV or receiver?

Do these terms describe two different entities or one and the same, just from different angles (development/production and operation/repair)?

Answer 1

The electronic module can be soldered into a non-separable screen, it can be filled with a compound (warriors love this) - i.e. they took a repairable printed circuit assembly and turned it into an unrepairable vandal-resistant brick.
This is just a guess.

Answer 2

Different things. A printed circuit board is a printed circuit board. What is a "printed circuit board", do you understand? Board made by printing. What is printing and where is the printer for boards, no need to explain, I hope?
Another point of reference is soldering - the components are attached to the board by soldering. I'm not sure that there is something about this in GOST for printed circuit boards. But in practice, some other methods of fastening to printed circuit boards are negligibly rare.
And an electronic module can be either a printed circuit board or something assembled from components by surface mounting (with soldering, with spot welding, with twists, with terminals). And even a microcircuit (not to be confused with a board) fits the description of an electronic module, but it is not printed.

Answer 3

I think the point is this:

Structurally and functionally finished radio-electronic device or radio-electronic functional unit

.
Those. pay - less finished.

Answer 4

Electronic module - Structurally and functionally complete radio-electronic device
The electronic module consists of printed circuit assemblies (but not necessarily, it can be a socket block with fuses and there are no printed circuit nodes inside).
