Prepare for the most important light etching "carving" that follows. The selection of rigid-flex boards for export is the most important! At least these standards must be met.
Especially when the PCB process is complex and requires a super four pin system at the upper end, which first two layers should be noted?

All raw materials must have supplier qualifications, so once there is a supplier application, it is necessary to be qualified to apply, otherwise only another one can be selected.
For hardware engineers designing, the emergence of PCBs has brought more convenience, reduced costs, improved work efficiency, and increased debugging efficiency.
In order to make the design of the circuit board meet the Functional requirement of the actual project, communication is usually carried out by drawing or design,
For the safety inspection of PCBs and components, with the failure of PCBs and components, the inspection method can almost be similar.
The basic concept of DFM is to use reasonable design and engineering strategies to ensure Supply chain security and satisfy designers.
The reliability analysis generally includes various considerations such as the design of the board surface, drilling design, and benchmark design. However, despite rigorous PCB design.
”We all know that the important process of designing a PCB can only go through a long process. This is a long process.
”Now a new design project is constantly developing, which can start from a simple printed circuit board layer.
The above principles are very helpful for beginners in PCB design, and can provide some tips to help them improve design quality.
In fact, the design of circuit boards can only be divided into levels based on the circuit diagram. Currently, there are also some basic work in PCB design, and only by comparing the basics can we achieve twice the result with half the effort.
