DIE ATTACH solid wires

DIE ATTACH solid wires

Colonne 1

Major advantages of the MBO Preform solid wires  :

  • High purity and free of oxides
  • Free of organic contamination on solid wire surface (elaborated extrusion process constantly improving by MBO engineers)
  • Wide range of available diameters (from 18 mils to 40 mils). Others diameters possible on request.
  • Low voiding solid wire (< 5 %).
  • Fully compatible with automatic wire dispensing machine.

General characteristics :

The reliability of electronic components is crucial. Thermal and mechanical fatigue are key parameters in the occurrence of defects.
A perfect joint is very important to get the best thermal performance. Good wetting as well as low void rates help to create a solder connection with highest reliability. MBO provide solid soft solder wires that are flux free and especially optimized for high performance components and die attach applications. They are manufactured by a controlled process in order to ensure the optimal quality.

DIE ATTACH OP9 M Di solder paste

Colonne 1

DIE ATTACH OP9 M Di solder paste :

Major advantages of the MBO DIE ATTACH solder paste:

  • Very good behaviour in dispensing
  • No clean and halogen free formulated
  • Extra clear and colourless residues
  • Low voiding for long term reliability solder joint

Organic No Clean OP9 M Di solder paste has been developed in the MBO laboratories. It is specially designed to offer a high level of activity while leaving very low residues, very clear and non-corrosive. This product, suitable for dispensing, meets the international requirements of the electronics industry.

  • ORL0 classification according to J-STD-004
  • Halide free.
  • REACH compliant
  • High activity.
  • Very low residues, neutral and colorless.

Organic No Clean OP9 M Di solder paste is manufactured in strict compliance with current international standards.
