Earth Conscious PWB

There is a fast growing concern for environment problem on all over the world.
For every enterprise, environment is one of its most important topics.

In the field of PWB, eco friendly PWB is, of course, being developed and “B²it PWB”provides earth conscious PWB with its original interconnection technology.

B²it, Eco-friendly PWB

B²it tech is eco-friendly with its following features.

No Drilling and Plating

→Reduction of Industrial Waste, Washing Water and Chemicals.

Wide Choices of Insulation

→Halogen-free･Br-free Reflow Available

Comparison of Manufactureing Process

B²it is a build-up PWB whose layers are connected with Ag paste.
Therefore it does not require drilling and plating to reduce Environmental Burden.

Decreased Emvironmental Effect with B²it Tech.

No Drilling		No Industrial Waste(rubbish from holing)
No Plating		Reduced Amount of Chemicals for Planting
		Reduced Amount of Washing Water
		Reduced Amount of Industrial Waste (drain neutralizing dirt)


	B²it, Eco-friendly PWB
	B²it tech does not require holing and plating process that conventional manufacturing processes require, and achieves lower negative effect on environment from its manufacturing process. DNP is pursuing its further ecofriendly manufacturing process.

*Our halogen free printed circuit board has acquired the recognition of UL (Underwriters Laboratories Inc.) standard.

Halogen free PWB(photo:PWB for our product "Yubi-net-pass")

The surface is blue because its SR is halogen free.
