Names of NT products for transfer have three parts connected by a hyphen as shown below. NT-XXX-ABBCC NT-XXXX-ABCC The first “NT” is an abbreviation for NITRON -T^TM, which is Nitto’s optical semiconductor encapsulating transparent resin. The second part generally consists of 3 or 4 letters, and represents the product group with identical main material and composition. Products with the same letters will show similar major properties. If the last letter is either H or S (NT-300 Series) this shows the molding speed difference. The last part consists of 4 to 5 numbers, and indicates the color code, cut-off wavelength, and content of optical dispersant. See the following chart for descriptions.

Curing time	Adhesion with chips	Adhesion with the frame
		Capable	Good	Excellent
H Series (2 minute curing type)	Good	NT-301H	NT-300H	NT-309H
	Excellent	NT-305H	NT-304H	NT-306H
S Series (45 second curing type)	Good	-	NT-300S	-
	Excellent	NT-307S	NT-308S	-

The official name for the products above have 4 or 5 numbers added (i.e. NT-3XXH-ABBCC). These numbers represent properties such as color phase, cut-off wavelength, and optical dispersant content rate. Products with reduced particles have the letter Q added (i.e. NT-3XXHQ－ABBCC).

Regarding the cleaning of the die for the NT-300, the following conditions are recommended.) Clean and deburr with a cleaning resin.) Then to condition the die, mold the conditioning resin* a few times.

• * Conditioning resin: KNJ-P (Nitto Denko product)
