[#62] 玩DIY師兄們,用邊隻錫線好    
錫礦石是錫石(SnO2),錫礦中的原礦石含約5%的錫,礦石被粉碎和提純後,再在精鍊爐,由碳還原出來。

銲接時產生的煙,源於助銲劑flux所用的松香rosin。

我無銲錫綫好多年,因為全部直接由供應商取樣品來試。

鍚銲鍚問題不大, 但PCB或接綫柱等, 如果係電鍍上貴金屬(如下圖)既話, 就多要用上氰化物了:

#11 "呢 d 老牌錫線靚野黎, 又平又正, 你地點解唔識貨? 只信名牌, Kester 我好多年前買落, $55/lb only。平時用英國 老牌 Multicore, 都係好野,"

Kester flux 331 is a water soluble formula, it contains organic acid. The residue need to be cleaned after soldering.

If you are serious with you job, you should clean it. If you don't mind one day the solder joints are corroded, of course you can just let it be.

If you are lazy, better use No-Clean solder wire.

"你地真專業, 研究到咁深入"

Yes, my profession is supplying soldering material.

Agreed, but DIY'ers should have a right choice with some basic knowledge too.

請問咩工業咁勁?
軍工嗎
我前兩年做過紅M電鑽
歐洲廠既測量儀器講明要無鉛架wo
含咩佢唔會點理(日本仔除外,講明含銀)
可以我果d儀器做俾canxx nikxx用太民用
無你講既特殊要求

Consumer products doesn't mind using Lead-free solder as you probably will buy a new one before it, such as Digital Camera, breakdown itself.

As you mentioned, Military also Avaiation, Automotive, Medical products... are reluctant to change to use Lead-free solder due to these is no solid record for its realiability.

You know why Japanese companys request to use Silver content solder ? It may because it is a Japanese company (Senju) invented Silver content Lead-free solder, every manufacturer needs to pay royalty fee to them when making this kind of solder alloy. Japanese helping Japanese is understandable. Anyway the patent is expired and no more royalty need to pay.

#75 試問又有誰做過科學性測試呢?還有,你認為這麼多不同的品牌,都有自家的焊錫科硏專利/特別工藝調配嗎?都有自家的焊錫工廠嗎?還不是靠OEM工廠生產,自家品牌的一張貼紙,還有廣告....

哈,a good question, solder professionals focus on durability and safety, can't expect* may be too harsh* them to care on sound performance. 針冇两頭利!

人總是有"理性"同"感性"兩個行為的, 當身處工作需要, 理性既"瀉鑊"模式會自動啓動, 當想音質要更上一層樓既話, 加少少野, 賣個天價, 感性的聽覺會話俾自己聽好值得, 自然會樂在其中的!!

I did proivded different Ag content solder wire to a DIYer to make Interconnect cable. He prefered Silver contect 4% > 3% > 2%. Of course it is only his preference. Another DIY perfers Lead wire, the more Lead the better according to his experience.

So there is no absolute "Good sound" solder. My 2 cents.

其實大部份廠(軍工及汽車除外)
都係買牌子貨
唔會好似你地咁check
我以前公司係日本上巿既廠都無咁做
只係用光普儀測有無鉻呀果一d rhos唔可以有既物料
Consumer既野好少好似你地咁
無鉛產品多,你叫佢地用有鉛仲難
