The Keysight N3304A is a 300 W (0-60A, 0-60V) electronic load module for use in either the N3300A or N3301A electronic load mainframe in system applications. The N3304A load module is fast and accurate, for programming in constant current, constant voltage, or constant resistance modes, or for making voltage, current or power measurements. The N3304A can also digitize waveforms.
Testing multiple output dc power supplies and dc-dc converters can be very time consuming if each output must be tested sequentially. If measurements are being made through a MUX using one DMM, this is what will happen. Using the built-in measurement capabilities of the N3300A electronic loads, all outputs can be measured simultaneously. Alternatively, multiple single output power sources can be tested simultaneously.
A single GPIB address is all you need for complete control and read-back of the N3304A load module within a single N3300A or N3301A mainframe. The N3304A electronic load provides fast operation and the accurate programming and read-back needed for high-volume DC power supply test systems.

Molding is the forming process. Compression Molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, while heat and pressure are maintained until the molding material has cured.
It is followed by two steps: Preheating and then Pressurizing.
It is generally used for thermosetting plastic.

Differential Scanning Calorimetry (DSC) measures the temperatures and heat flows associated with transitions in materials as a function of time and temperature in a controlled atmosphere.These measurements provide quantitative and qualitative information about physical and chemical changes that involve endothermic or exothermic processes, or changes in heat capacity.
What Can we measure using a DSC ?

  • Glass transitions
  • Melting and boiling points
  • Crystallization time and temperature
  • Percent Crystallinity
  • Heats of fusion and reactions
  • Specific heat
  • Oxidative/thermal stability
  • Rate and degree of cure
  • Reaction kinetics
  • Purity

Plasma cleaning is the process of removing all organic matter from the surface of an object through the use of an ionized gas called plasma. This is generally performed in a vacuum chamber utilizing oxygen or argon gas. We use this equipment to clean the surface of PDMS devises and bond PDMS/PDMS or PDMS/ Glass surfaces.
