Clear molding compound for optical semiconductor NITORON T(NT) Series

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.

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)
