The above is the overview of optical module PCB and optical device simulation. There are not many things to simulate, but there are also many places to be carefully handled.
The above is the knowledge that optical module PCB and optical device cascade simulation need to master. Compared with chip packaging and board level PCB, there are a lot less things, and because there are a lot of repetitive things in optical module simu
This paper first introduces what is impedance and impedance type, then introduces the PCB circuit board why to do impedance, describes the significance of impedance for PCB circuit board, the specific follow Xiaobian together to understand.
In blu-ray machines, flexible circuits are used to connect the laser to the main circuit board. Please note that the flexible circuit on the laser head circuit board needs to be bent at right angles.
Multiple flexible PCB stiffeners are used to provide higher stiffness and strength for flexible PCBS. They are usually placed in key locations on the circuit board and can be made of different materials, including metal and plastic.
A stiffener board is an extra layer of material on a flexible PCB that helps prevent the board from bending and breaking. Flexible pcb stiffeners help prevent mechanical damage during product handling and use.
The bending radius of flexible PCB is a key index to understand the design capability and the manufacturing process of flexible PCB. Different flexible circuit boards use different layers, which affect the bending radius of flexible PCB. You can learn how
The most important factor when choosing a PCB laminate is to ensure that it is compatible with your RF and microwave PCB design requirements. For example, if you need high frequency performance, you may want to choose a material with a high dielectric con
Antenna return signal loss is an important consideration in RF and microwave PCB design. The return loss of any RF and microwave PCB board is defined as the power ratio between the forward and reflected waves at a given frequency.
HDI pcb boards support more electrical connections per unit area than traditional single-layer boards. This is mainly due to the use of multiple layers as interconnects between layers in both laminated and blind holes.
HDI PCBS are commonly used in avionics, military and aerospace applications where reliability is critical. A typical aircraft requires hundreds of microcircuits, sensors and other electronic components that need to be connected with hundreds of wires.
