Analysis of back drilling PCB
PCB Engineers who do hardware know that the design of PCB vias is actually very particular. Today, I want to share the technical knowledge of via hole and back drilling in PCB.

Usually, the design and manufacture of printed circuit boards (PCB)
As important as the design of the main circuit itself.
Manufacturers are increasingly using compact, flexible PCBs to assemble and organize electronic circuits.
The PCB can include one or more insulating plates on which copper layers and conductive signal traces have been etched or printed.
Depending on the complexity of the circuit, the manufacture of printed circuit boards usually includes anywhere from a single-layer PCB to an eight-layer PCB (or more)layers.
This paper discusses pcb types based on layers and rigidity.
If you have a very basic circuit, your PCB manufacturer may recommend the use of a single PCBsided PCB.
This is the least complicated PCB in the entire circuit-
Including electrical components and copper traces-
Included on a single insulation board. A double-
Side panels have circuits that are a little more complex than individual circuitssided board.
As the name implies, both sides of the substrate are used to accommodate circuit components.
Perforated technology is often used when making dual-hole pcb
Double-sided or multi-layered.
Complex printed circuit board manufacturing is through multiple
A layered pcb consisting of multiple substrates with an insulating layer between each substrate.
Depending on the complexity of the circuit, this pcb can range from 2 layers to 4 layers to 8 layers, and can even extend to 42 layers in highly complex circuits.
Different applications based on rigid pcb types require different types of pcb.
For example, rigid PCB is the most common and can be found in daily life
Use consumer electronics such as computers, televisions and mobile phones.
This plate will crack or break when the bending exceeds a certain limit.
Another common type of PCB supplied by PCB manufacturers is flexible PCB.
The circuit in this PCB is assembled on a thin flexible insulating material.
This allows the PCB to bend and bend as needed without damaging the circuit or insulating material.
You may see flexible pcb being used in devices such as medical devices, flexible heaters, and even hearing aids. The rigid-
Flexible pcb is a combination of rigid and flexible pcb.
These circuits are used in aerospace and military applications and require very dense circuits. Rigid-
Flex pcb helps to save a lot of space and thus produce electronics with much less weight.
For a limited number of circuits or large circuits, it is possible to make printed circuit boards
Mass production.
It is critical to choose a PCB manufacturing company with a good track record.
