Magnetics : How Exxelia supports the key processes ?

Cleaning procedure 

The cleaning of the PCB boards is evolving from solvent (as isopropylic alcohol,...) to highly alkaline water based cleaning medium. EXXELIA has performed an extensive study to offer robust technologies to withstand these current cleaning processes. The qualification procedure has included thermal shock, burn in and mechanical testings. EXXELIA has defined gluing, marking, varnishing processes that allow the products to go through more than 5 cleaning cycles and operating up to 180°C. 

Processes compliant to ESA and NASA outgassing standards have also been defined for products specified up to 140°C. 

 

Wire integrity 

EXXELIA has qualified specific processes to ensure wire integrity for better insulation. The wire undergoes mechanical, chemical and thermal stresses during the winding and cabling process steps. EXXELIA has set up a dedicated process to reduce the impact of these manufacturing steps and improve the overall reliability of the wires and products. 

 

Finishing 

EXXELIA offers several types of components: Surface Mounted Device, Through Hole or lead terminations products, system integrated components. 

 

Packaging 

Products are available on trays and, upon request, on reels for easy pick and place, ESD compliant EXXELIA products offer components compliant to IPC/JEDEC standard J-STD- 020 with TP = 260°C and tP = 30 seconds. 

Are Exxelia's magnetic components compliant with industry standards?

Yes, Exxelia's magnetic components are designed and manufactured to meet or exceed industry standards and certifications, including RoHS, REACH, and MIL-STD.

What are the primary uses of toroidal magnetic cores in electronic applications?

Toroidal magnetic core primary purpose is power conversion in electronic applications as inductors, common modes chokes, power transformers, current or voltage measurement transformers, gate drive transformers, ... There are three types of soft magnetic cores: powder cores, ferrite cores, and tape wound cores.

 

Powder Core: 

  • Distributed air gap cores with high resistivity, low hysteresis and eddy current losses, excellent inductance stability DC and AC current 
  • Primarily used in power inductor applications,differential inductors, boost inductors, buck inductors, and flyback transformers. 
  • Main materials used: Molypermalloy (MPP), High Flux, Kool Mµ®,... 

 

Ferrite cores: 

  • Low losses at high frequencies, 
  • Low cost and wide variety of available shapes and sizes 
  • Extensively used in switched-mode power supply (SMPS) and radio frequency (RF) transformers, inductors and common mode chokes. 
  • Uncoated, epoxy or parylene coated 
  • All available materials are used 

 

Tape wound cores

  • Higher B (saturation flux density) 
  • Design can be smaller 
  • Primarily used for common-mode chokes, current measurement transformers, power transformer,... 
  • Materials: nickel-iron alloys, grain oriented silicon steel, amorphous materials or nanocrystalline,...
