Typical Reflow Profile/Installation Notes

reflow

Installation Notes:
* The rate of heating and cooling must be controlled to preclude thermal cracking of the devices.Processes, heating or cooling, should not exceed a rate of 200°C per minute. Spikes must not exceed 100°C maximum for any solder operation. Avoid forced cooling or contact with heat sinks, such as conveyor belts, metal tables or cleaning solutions, before the units reach ambient temperatures.

  • A typical re-flow profile is provided above.
  • All solder-able surfaces must be free of contaminants for maximum solder ability
  • The relative mass of all components should be considered when establishing a re-flow procedure.
  • Higher density board populations may take longer to achieve re-flow temperatures.
  • SMT Products can be cleaned via solvent based, aqueous, semi-aqueous, and alcohol based systems.
  • Units must be completely dried as moisture could cause false electrical performance readings.
  • Mishandling of product may result in damage to the device (please do not bend RF leads, if applicable
  • All SMT filters are assembled using SN96 high temperature solder, as a minimum.
  • K&L recommends that customers use SN60 or SN63 or an equivalent during installation for signal and ground connections.
  • The rate of heating and cooling must be controlled to preclude thermal cracking of the devices.
  • Processes, heating or cooling, should not exceed a rate of 200°C per minute.
  • Spikes must not exceed 100°C maximum for any solder operation.
  • Avoid forced cooling or contact with heat sinks, such as conveyor belts, metal tables or cleaning solutions, before the units reach ambient temperatures.

About The Technology

MPG_KLM_FL_BP_FIX_LE_MUL_5KCB20-310-U180

Lumped Element

LC filters are passive devices, smaller than the operating wavelength, to permit a wider bandwidth within compact packaging. Special design capabilities for our Lumped Element Filters include, but are not limited to, elliptical, pseudo-elliptical, amplitude equalization, group delay equalization, bessel, gaussian, and highpower.
