Контрактное производство электроники под ключ в Китае
For some parts that cannot be inspected by appearance, as well as the through hole inside the PCB and other internal defects, X-ray fluoroscopy system has to be used for inspection.
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.
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.
Effectively control the cost of PCBA OEM materials: first, active planning and management, second, strengthen monitoring, third, comprehensive application
Screen printing: This is an unnecessary component, the main function is to mark the name and position of various parts on the circuit board, easy to maintain and identify after assembly.
Output PCB layout picture information in the form of Gerber file. This format is the standard for PCB files, which are the form of CNC files used by photo plotters. In addition to the Gerber file, borehole information is generated as well as screen printi
High Density Interconnect (HDI) is a technique for creating high speed and high density PCBS. HDI uses blind and buried holes to increase signal density and thus improve the performance of printed circuit boards.
Formal product lifecycle management can achieve significant improvements throughout the development phase of a project. Benefits are limited to project management and all stakeholders, including the product design team.
The PLM process should support the collation and management of product information into a single authentic source from which product documentation, such as user manuals or marketing materials, can be generated.
In a more complex electronic circuit design, you can use the circuit equation design method, this method is a digital model for analog design, greatly simplified the design process.
One of the key considerations in designing rigid-flexible PCB is the width and spacing of the wires. This is important because the wiring needs to withstand the mechanical stress of bending during assembly.
