Préparation des couches internes PCBTwo methods for the treatment of the inner layers can improve the adhesion of the resin on copper. the MCT : acid oxidation, it’s a revolutionary process for exceptional adhesion of the resin on copper.

Acid oxidation process the MCT

Because multilayer PCBs reach the limits of technological process of manufacturing, with considerable added value, this implies very reliable processes
The revolution in the treatment of inner layers prior to multilayer lamination and bonding :

  • Eliminates wedge voids and « Pink Rings »
  • Suitable for horizontal and vertical lines
  • A fast, economical and reliable

This is a fast process because short

An economic process: not reducer, easy for waste water treatment

IIt’s a reliable process: more resistant to manipulation, high adhesion (no pink ring).

Printed circuits Multilayer buried holes and blind holes• Operating temperatures moderate.
• Does not require micro-etching.
• Operates in horizontal or vertical chain.
• Low cost of equipment and use.
• High efficiency, small footprint.
• Low water use.
• Simple treatment of wastewater.
• Removes the reducer Black oxide.
• The treated copper is more resistant to handling.
• Excellent bond stresses: 7 to 16 N / cm
