What is the Embedded PCB ?


What is the Embedded PCB ? 
 - A PCB that allows electronic components to be planted inside the PCB to increase the surface mount surface area, reduce the size of the board, and provide designers with a variety of designs.


Benefits of Embedded PCS :

- Reduce PCB size and finished product size
  
 - Increased durability   - Improved heat dissipation performance through thermal conduction design
Types of Embedded PCB

OPEN Cavity Type: Creates a multi-layer PCB and inserts a chip into it. It connects wire bonding, Flip Chip and PCB Pad.


Close Cavity Type: Multilayer PCB layer structure Put on the MLCC or Chip into a specific layer and fill in a resign.

Required skills:

 - Cavity Laser, Depth Router, Half Cut  - Lay-Up

- Resign Filling  Applications
- Smartphone:


- Capacitor Embedded PCB: Put the capacitor inside the PCB to reduce the component mounting size.

- R / F Module:IF put on R / F Module inside the PCB and use it for product history management and Smart production system.

What is Aspect ratio in PCB ?





The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side – the ratio of width to height, when the rectangle is oriented as a "landscape"

The aspect ratio is expressed as two numbers separated by a colon (x:y). The values x and y do not represent actual widths and heights but, rather, the relationship between width and height. As an example, 8:5, 16:10 and 1.6:1 are three ways of representing the same aspect ratio.



Aspect ratio in the PCB is the hole size for the depth of the drill.




 PTH (Plated Through Hole) is calculated as X: Y and is mainly written as 00: 1
In case of LVH (Laser Via Hole), X / Y x 100 = 00% is calculated as% for operator's convenience.
