This instrument is compatible with four standards of site to measure surface roughness of various machinery-processed parts, calculate corresponding and clearly display all measurement parameter. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism by the sharp built-in probe. This roughness causes displacement of the probe which results in change of Inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive dsp processes and calculates and then Outputs the measurement results on lcd. * multiple parameter measurement: ra, rz, rq, rt * highly sophisticated inductance sensor * four wave filtering methods : rc, pc-rc, Gauss and d-p * built-in lithium ion chargeable battery and control Circuit with high capacity * small in size, light in weight and easy to use * can communicate with pc computer for statistics, Print and analyz by the optional cable and the Software for rs232c interface. *manual or automatic shut down. The tester can be Switched off by pressing the power key at any time. On the other hand, the tester will power itself off About 5 minutes after the last key operation.

High-TG PCB High Temperature PCB fr4 Material The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from a hard, glassy material to a soft, rubbery material. Circuit board material must flame-resistant, it canâ??t be burned at a certain temperature and only be soften. The temperature point is called the glass transition temperature (Tg). The higher Tg point means higher temperature requirement during lamination. And the Aluminum clad Circuit Boards will be hard and crisp, which will affect hole and the electrical properties. Ordinary PCB materials at high temperatures, not only will be soften, deformation, melting and other phenomena, but also the mechanical and electrical properties decline sharply. General fr4 Tg is 130-140 centigrade, moderate Tg is greater than 150-160 centigrade, High-Tg is greater than 170 degrees. The higher of Tg, the better performance of PCB heat resistance, moisture resistance, chemical resistance, stability and other characteristics. FR4 is a code name for grade of Epoxy Glass material. Tg means Glass Transition Temperature. When the working temperature reaches to the melting point, that means the temperature exceeds the Tg value, the status of pcb material will be changed from glassy to liquid, which will affect the function of pcb. And this value is related to the stability of the pcb dimension. As usual, made with Tg â?¥ 170â?? pcb material, which is called high Tg printed circuit board. With the rapid development of the electronics industry, high Tg material is widely used in computer, communication equipment, precise apparatus and instrument and etc.
