在SMT工艺流程中，锡膏印刷是非常重要的一环，而钢网无疑又是锡膏印刷质量好坏的重要因素之一。一般情况下，一张钢网的张力需要保持在30-50N/cm。钢网张力过小，易引起少锡，偏移等印刷不良, 张力太大脱膜的时候会拉尖会缩短使用寿命等，所以检测钢网的张力显得尤为重要。TETKOMAT张力计适用于各种类型丝网版张力的测试，指针式指示张力（单位：牛顿），无需任何电源。TETKOMAT可随意检测拉紧网布任意位置上的张力，该张力计一般测试网版的径向和纬向张力，使网版达到径、纬线方向一致。
量测范围:以7-50N/cm的量测范围提供可靠、简单、快捷及全方位的网布张力测量，并可免除以人手或触感进行量测的误差。 
Screen printing tension meter
The TetkoMat is a portable, compact, mechanical tension measuring device for accurate and consistent measurement of all screen printing fabrics in Newtons per centimeter (N/cm).
The TetkoMat consists of a shock-resistant measuring base with a precision mechanical dial indicator. The TetkoMat works on the principle of force deflection; the unique design of the meters 3-point measuring base permits accurate measurement on the screen (polyester, nylon or wire), independent of the screen frame or stretching device. Protected in a convenient, rugged plastic carrying case.
Features:
Substantial improvement in tension measuring methods as compared to touch control, gauging by percentage of fabric elongation, and air pressure values.
Accurate tension measurements will improve registration and reduce rejects, resulting in increased productivity
Reproducible and uniform tension measurement, screen after screen. |
