in fact, no matter how to produce or design, ultimately can not be separated from the consideration of money, so should all the factors into the amount to make the final measurement standard to choose a suitable plate method.
Printed circuit board, also known as printed circuit board, printed circuit board, shortened to build and circuit board, often use English (PCB Printed circuit board) or write PWB (Printed wire board), printed with insulation board as the base material, c
In the use of solder paste is to pay attention to the following requirements: 1. After the solder paste is purchased, write the number for each can of solder paste. 2, in the form of sealed storage in the constant temperature and humidity of the refrigera
Through hole is one of the important components of multi-layer PCB. From the perspective of function, through hole can be divided into two categories: one is the electrical connection between each layer; The second is the device fixing or positioning.
On the automatic surface mounting line, if the PCB is not smooth, it will cause inaccurate positioning, components cannot be inserted or affixed to the holes of the board and the surface mounting pad, and even crash the automatic inserting machine.
PCB deformation causes can be divided into thermal stress and mechanical stress. The thermal stress is mainly produced in the process of pressing, and the mechanical stress is mainly produced in the process of stacking, handling and baking.
PCBA is one of the basic components of electronic components, PCB it through surface assembly technology (SMT), and the whole process of DIP plug-in insertion, known as PCBA process.
In the process of PCB production, the physical and chemical properties of each material are different, and the thermal stress residual generated in the pressing process leads to the bending and warping of the board.
After determining PCB related selection factors, the payment method should be selected, including whether to issue bills, express logistics, packaging type and flying needle test. If there are special requirements, the information should be noted.
In PCB production process, in addition to pressing, there are several high temperature treatment processes, such as welding resistance, characterization and hot air smoothing.
it is critical that your PCB components be accurate and functional. Therefore, dealing with reliable PCB component manufacturers and service providers is critical.
All of these tools are important when creating various layers and using different components to make printed circuit boards for complex applications.
