What are high TG circuit boards and high TG circuit board process capabilities

 　　Meaning of high TG circuit board


　　At present, every enterprise and individual demand for high TG circuit board is adding, now China circuit board factory will introduce what is high TG circuit board.


　　High Tg refers to high heat resistance. Generally speaking, the board of Tg is further than 130 degrees, high Tg is further than 170 degrees, medium Tg is further than 150 degrees, and generally Tg ≥ 170 ℃ PCB is called high Tg PCB.


　　With the rapid-fire- fire development of the electronic sedulity, especially the electronic products represented by computer, the development towards high function and high multilayer requires the advanced heat resistance of PCB base paraphernalia as an important guarantee.


　　The appearance and development of high- density installation technology represented by SMT and CMT make PCB more and more thick from the support of high heat resistance of substrate in small perforation, fine circuit and thin form.


　　The Tg of the substrate has been bettered, and the characteristics of the PCB, analogous as heat resistance, moisture resistance, chemical resistance, stability resistance,etc., will be bettered and bettered.


　　The advanced the TG value, the better the temperature resistance of the board. Therefore, in multitudinous lead-free processes, high TG is more considerably used.


　　Maybe the below prolusion is too confusing for you to understand. In order to make you more understand the high TG circuit board, we can divide it into the following points


　　The critical temperature at which the substrate melts from a solid state to a flexible fluid is called the Tg point, which is the melting point


　　The advanced the Tg point is, the advanced the temperature demand of the board is when pressed, and the pressed board will be hard and brittle, which will affect the quality of the mechanical drilling (if any) in the after process and the electrical parcels during use to some extent



　　Tg point is the maximum temperature (℃) at which the substrateremainsrigid.That is to say, ordinary PCB base material at high temperature, not only produce softening, deformation, melting and other sensations, but also show in the mechanical and electrical characteristics of a sharp decline



　　Generally speaking, the board of Tg is further than 130 ℃, high-tg is further than 170 ℃, and medium Tg is further than 150 ℃. The Tg of the substrate has been bettered, and the characteristics of the PCB, analogous as heat resistance, moisture resistance, chemical resistance, stability resistance,etc., will be bettered and bettered.


　　Our products are high- perfection double- caste PCB, high-tg PCB, heavy bull PCB, flexible PCB, special substrate and customized published circuit board of various special conditions. These products are considerably used in every corner of life.


　　Our company has always been fully new to give guests with professional PCB processing, design, product services. Advanced special product outfit and testing instrument for PCB. Excellent technology also ensures that all kinds of possible problems can be answered easily.

What is the important role of the fuse holder? Improved structure of fuse holder

图片
  Fuse bracket wholesaler, fuse seat production --------------------------------------------------------------------- What's the important part of the fuse holder? The  fuse holder  is an electrical element installed in the circuit to give sequestration protection for the fuse and insure the safe operation of the circuit. It may damage some important factors or precious factors in the circuit, and may also burn the circuit or indeed beget a fire. PCB FUSE HOLDER However, also the fuse will fuse itself when the current abnormally rises to a certain height and a certain time, and a dangerous situation similar as a fire may do, If the fuse jacket fuse holder is rightly placed in the circuit. At this time, the fuse holder is insulated from the outside world., so as to cover the safe operation of the circuit. The field of fuse holder on- board protection of unresistant electronic factors is still fairly good, and there are still numerous outfit diligence in which unresistant p...
