Equipment for Education, Engineering and Vocational Training - SMD Technology Trainer & Lab Kit - Surface Mount Technology (SMT) is method for constructing electronic circuits in which the components are mounted directly onto the surface of printed circuit boards (PCBs). Electronics devices so made are called Surface Mount Devices or MSDs. An SMD component is usually smaller then its leaded counterpart because it has no leads or smaller leads. It may have short pins or leads of various styles, flat contacts, a matrix of balls (BGAs), or terminations on the body of the component (passives), unlike discrete components, SMD components have a huge vareity of packages (size). SMD Technology will be the order of the day for the electronics industry in the coming years. SMD offers Small size, consequent High Packing Density, High Reliability & Improved High Frequency performance. SMD Technology Kit to keep you in pace with the technology revolution.

Equipment for Education, Engineering and Vocational Training - Bernoulli’s Theorem Trainer & Lab Training Kit - Bernoulli's Theorem Demonstrator facilitates the students and the industrial professionals to explore the fundamentals of “Bernoulli's Theorem” in Fluid Mechanics. It states that, in a steady flow the sum of all forms of mechanical energy (kinetic, potential and pressure energy) in a fluid along a streamline is the same at all points on that streamline. It consists of classical venture of clear acrylic. A series of wall tapping allows measurement of static pressure distribution of convergent duct, while a total head tube is provide at the centre of throat. These tapping are connected to a bank of manometer tube. This unit has been designed with Hydraulic Bench to study the characteristic flow through convergent and divergent section. During the experiment, the water fed to the venture and the flow rate can be control by the gate valve at the outlet of venture. The venture is used to demonstrate the flow rate measurement and to determine the co-efficient of discharge.
