What are the elements belong to the halogen family?

They are fluorine, chloride, bromine and iodine, all of which are very active and used as a fire retardant for the semiconductor package material.

Harmfulness & the necessity for substitution

Toxic substances such as dioxin and difuran are generated if incinerated.

These substances tend to accumulate in a human body for a long period of time causing environmental hormone problems In particular fluorine, chloride and bromine are known to severe depletion of ozone layer when exposed to the atmosphere, and for this reason regulation is being increasing reinforced with EU leading such regulation trends.

EU and Japan are expected to take the lead in implementing the regulation beginning from 2008, and for this reason the halogen substance used for manufacturing the semiconductor must find a substitute.

JPCA(Japan Electronics Packaging and Circuits Association) JPCA-ES-01-1999 defines Circuits and method for "halogen-free"

Br < 0.09wt%(900ppm), CI < 0.09wt%(900ppm)

IEC(International Electrotechnical Commission) Finalized requirements of IEC 61249-2-21 :

900ppm maximum CI, 900ppm maximum Br

1500 ppm maximum total halogens

IPC - 4101B has adopted the IEC definition of halogen-free

900ppm maximum CI, 900ppm maximum Br

1500ppm maximum total halogens

Note

fluorine, iodine, and astatine (other Group VIIA halogens) are not restricted in the industry definition of "halogen-free."

The mass production plan is intended for a road map for each product, which will be implemented on a full scale when new technology development and preparation for the mass production are completed.

The production of the halogen-free products out of the existing products to be produced in large quantities will be limited to those products requested by customers.
