Embodiment Construction
[0028] The process implementation of this patent can be divided into two major parts, that is, the metal nickel master plate production process and the replication process of the resin code disc, which are specifically described as follows.
[0029] mastering
[0030] Materials needed for mastering:
[0031] 1) A glass substrate whose surface needs to be optically polished.
[0032] 2) The photoresist uses S1805 photoresist of SHIPLY company, and the photoresist solvent uses EC-SOLVENT of SHIPLY company. The ratio is 1:5.
[0033] 3) The adhesive uses 1% by volume disilane aqueous solution.
[0034] 4) The ratio of the developer solution is: 20 grams of sodium hydroxide and 100 grams of sodium pyrophosphate mixed with 8 liters of water.
[0035] 5) The sputtering process is used for metallization, and the nickel-vanadium target is used, and the ratio of the two is 1:99.
[0036] 6) The electroforming process uses nickel sulfide nickel balls as raw materials.
