我都有條國產無氧單晶銅, 有冇都冇所謂, 有改進就OK.

其實 所謂什麽“單晶銅” “單晶銀”， 廿年前已經有喇！ 不過戈陣時有 patent。 如今 patent 過晒期， 戈啲冒牌小販未出晒嚟囖！{:1_262:}

哈哈. o岩. 就係當佢堅先俾錢.
OCC 既purity已經上到去99.9999%
Oxygen 已經得返0.0001%以下
再落去有意思嗎?
如果你隻耳仔聽得到分別未有思意囉.............{:1_262:}

PCOCC就見過,PCOCC先係單結晶無氧銅
明白, 當純度達99.999...% 已經是OCC。

Actually nothing about purity, OCC or not only base on the crystal size, however, due to the manufacturing process, by needed to make a large crytal size, the copper must reach a minimum purity.
