UGPCB Enhances Multilayer PCB Manufacturing with Advanced Brown Oxide Lines

In the highly competitive world of печатная плата and PCBA manufacturing, УГКПБ has consistently demonstrated its commitment to excellence through strategic technological investments. The recent installation of state-of-the-art brown oxide treatment lines represents a significant milestone in our ongoing mission to deliver superior quality and reliability. This enhancement to our production capabilities specifically addresses the critical demands of многослойный Производство печатных плат, where interlayer adhesion quality directly determines final product performance.

The Critical Role of Brown Oxide Treatment in PCB Manufacturing

Brown oxide treatment, often called browning, is an essential chemical process in многослойная печатная плата production that prepares inner layer copper surfaces for lamination. This crucial step creates a microscopically rough surface with polar properties that significantly enhances the bond between copper foil and resin-based prepreg (ПП) материалы.

The fundamental chemical reactions involved are:

• Primary formation: Кузок + H₂O → CuO + H₂

• Secondary formation: 2Кузок + H₂O → Cu₂O + H₂

В УГКПБ, our advanced process precisely controls the formation of both copper oxide (CuO) и медь(я) oxide (Cu₂O) to achieve optimal results. The brown oxide layer serves multiple essential functions:

• Increases surface area through micro-etching, creating a uniform nodular structure that enhances mechanical interlocking.

• Converts non-polar copper surfaces to polar compounds that form stronger chemical bonds with resin systems

• Prevents delamination by creating a thermal barrier that withstands high lamination temperatures

• Eliminates contaminants that could compromise bond integrity
