Final surfaces / protective coatings

PROTEC

For the final surface treatment of printed circuit boards

The PROTEC series includes all the basins and tanks required for the treatment of printed circuit boards with chemical or organic protective coatings in a compact design.

PROTEC

Final surfaces / protective coatings

Protective coatings - end surfaces

After the PCB etching process, the exposed copper on the PCB would oxidize and impair the solderability of the components.
As one of the last steps in the production of printed circuit boards, the exposed copper surfaces are therefore coated with a final surface.
The end surface protects the underlying copper from oxidation and thus increases the shelf life. The final surface also has the task of

to increase the wettability of the connection surfaces during soldering.

The available end surfaces differ in terms of shelf life, typical application and price. However, the end surface is usually

by the further processing steps, the end product or the intended place of use of the end product.

PROTEC CH

OSP - Organic preservative for solderability - Organic protective layer

Organic Preservative for Solderability (OSP) is a cost-effective and environmentally friendly organic coating on copper.

OSP is a surface treatment for printed circuit boards that is also known as an anti-tarnish agent.

In the OSP-PCB process, an organic lacquer layer is applied to a clean copper surface using an adsorption process. Shelf life approx. 6 months.

PROTEC Sn

As a thin metal surface, immersion tin is ideal for processing modern surface-mounted components.

The planarity of the PCB surface is not affected by the thin end surface, the thermal load on the PCB

is very low compared to hot tinning. The copper surface is coated with a protective metallic tin layer.

coated to maintain solderability during the storage period (≥ 6 months) of the unassembled PCBs. Shelf life approx. 6 months.

PROTEC NI/AU

Chemical gold is also known as ENIG (electroless nickel immersion gold). Like immersion tin and immersion silver, electroless gold is a very planar

PCB surface with very good oxidation properties. It is ideal for fine-pitch and bonding applications. Shelf life approx. 12 months.

PROTEC Ag

Chemical silver is a printed circuit board surface that is chemically very similar to tin, but has better properties in oxidation and contact applications.

However, electroless silver is also a sensitive surface and therefore has a low market share. Chemical silver is very suitable for high-frequency applications.

Shelf life approx. 6 months.
