各位好,又是我,愛東搞西搞的那位XD
上次發了一篇改USB Type-C鍵線分離
https://www.ptt.cc/bbs/Key_Mou_Pad/M.1626871263.A.FA5.html
完成後想說這把鍵盤總算是可以正式上線了
結果上線僅僅20分鐘
內心嚴正地告訴我->果然紅軸我不行XD
所以就果斷拆軸了
(拆軸真的累...)

沒拆還不知道原來裡面髒的這麼噁心..

正好最近提前段落軸很流行
我也很想嘗試看看
就在淘寶訂了最便宜的聖熊貓+長彈簧
等到貨的期間
想到萬一手感不是我喜歡的
那不就又要解焊一次軸了嗎..
想想渾身不舒服了起來
經過考慮 雖然覺得工程不小
但還是決定做一張PCB板
畢竟這樣完成度才夠XD
//以下工程開始
FILCO Majestouch 2的Scan Matrix可以在網路上找到

有興趣的話同一頁面你會找到跟FILCO一樣Scan Matrix的鍵盤
追溯源頭會發現他們是出自同一個OEM廠商
網路上的資訊不可盡信 還是要測試自己的實體電路板比對一下是否一致
不然有可能PCB做出來馬上變報廢品XD
對了 補充: 二極體方向為 ColToRow
(因為我已經肉身測試OK了 有需要的人可以直接用)

插拔座的零件我看凱華跟佳達隆都有做
網路上的評價似乎凱華的好一點點
但樣本數不多 不知是否為真
這零件淘寶賣家很少 所以價格低不下來
一顆算起來約2.5台幣 *104顆 -> 貴!
防鬼鍵的二極體1N4148我選玻璃封裝SMT的(LL34)
鍵盤的三顆指示燈選綠色3MM LED (原本紅色LED 本人工程師感到心理不安..)
連USB線的座 為PH2.0 5P
給主控插的排母為2.0間距 18P 高4.2mm
零件大概是這樣
FILCO的PCB零件種類不多,因為主控是分離的
接下來就是苦戰了
量尺寸是我最擔心的地方
鐵板與PCB之間這款鍵盤有5個螺絲
5個螺絲的分布沒有規則 彼此也沒有對齊
只要量測時誤差太大 到時PCB就鎖不上鐵板
PCB板上的線路倒是還好
不複雜,就是很多而已..
另外熱插拔鍵盤被捅爆時有所聞XD
所以我希望能加強插拔座的堅固程度
第一我把pad加大一些(相較於插拔座的原廠建議尺寸)
第二我在每一個pad上額外做了兩個via 希望有"釘子"的功能

在與軸同一面的四個角 都不走線
->讓軸的四個腳跟PCB接處的四個點盡量是同一個平面
成果:

取名為"Swappable"
跟 Convertible 做兄弟這樣XD

PCB與原廠完全同尺寸
該開的孔都有好好開 準準開
這樣一來聲音跟觸感才會與原廠相同
(我看過有些FILCO替換PCB 孔開的大 或是PCB面積縮小 甚至與鐵板固定的螺絲孔沒開)
等待PCB生產的時間軸先到了
就先來小潤一下
軸板是3D列印的

然後我發現這個軸的總行程只有3.1mm
不知道元祖的聖熊貓是不是也是這樣
一般MX軸的行程是4mm
不過這正是我想要的 算是誤打誤撞
總行程 18.08-14.975 = 3.105mm

PCB到了!
紫色!!!!XD
因為PCB最後會包在內部 基本上沒有存在感= =
希望至少在插拔軸的時候 能讓人知道他不是原廠的PCB
所以用了相對少見的紫色~

原廠PCB上的LOGO樣式沿用

與鍵盤下殼接觸的地方有標示

上電測試鍵位觸發OK後才焊零件

裝上下殼

裝上軸(就是為了這個功能!!!)

回歸低調

只有從LED燈色才有可能發現這把鍵盤或許有跟別人不同的地方?!

呼~~ 終於舒服了 XD
感謝收看~
