The purpose of the prompt is to help the quality and improve the quality of the PCB design.
There are two basic BGA materials: Ceramics and Organic (FR-4).
Different jewelry designs use different rules. The most common is FR-4B products and low-level data. 4 It is the material of choice for the merchant's processing technology. 4 The size and long solder paste surface are the preferred material for merchant processing.

Number of Layers: (Regarding the breakout from the BGA Only)
|Pitch||Breakout Escape rows||No. of Layers|
|0.8mm||T-4; Any other-6||4|
Any additional layer pair can add 6 rows.
The following is a breakthrough escape example using 1mm BGA and 4mil trace x 4milspace.
It is possible (and recommended) to divide the BGA area into four equal parts. So as to make the escape more clever and flexible.
In order for a circuit board with one or more BGA components to be effective, a low number of layers must be kept low, and strict restrictions must be made with the PCB manufacturer.
