Now, various activity trackers, such as fitness bands and smartwatches, can also measure heart rate and other biological indicators or monitor sleep quality. Many people are excited about the new opportunity to track their fitness levels, giving rise to t
Acrylic three anti - paint flexibility can provide comprehensive protection. Because it is a single component system, with good adhesion, simple operation, not high requirements for equipment and conditions, convenient construction, high transparency, hig
The higher the TG value, the better the temperature resistance of the plate, especially in the lead-free process, high Tg is often used. High Tg means high heat resistance.
In the future, the application of KPI will become more and more important and will become an objective basis for the improvement and evaluation of intelligent manufacturing related projects.
As time goes by, the size of the high-performance chip increases, the number of Solder Bump increases, and the substrate becomes thinner and thinner. In order to improve the reliability of the product, it is necessary to fill the bottom.
Vacuum in this context refers to the negative pressure in the operating area of the system and the low suction force just enough to prevent the etching fluid from creating a puddle effect.
Exposed to heat, humidity and pollution, it can still provide excellent electrical properties and maintain satisfactory weldability, but it will miss shine.
The plate with higher Tg can increase its ability to withstand stress and deformation, but the price of the material is relatively high.
In PCB production process, in addition to pressing, there are several high temperature treatment processes, such as welding resistance, characterization and hot air smoothing.
