SST25VF064C要用哪一種SPI socket呢?

文章變形蟲 » 週四 9月 16, 2010 5:55 am

SST25VF064C這顆包裝比較特別一點
請參考圖面(與SST25VF032B比較一下就知道)
圖檔
和正統的SO8W看起來很像
可是實際上頭尾是多出了一些
圖檔
不要小看這多出來的一些些
很多便宜的SPI socket都上不了會卡到
有些板子常喜歡把一些電阻和電容lay在頭尾的不幸的話可能因為這頭尾導致卡件
所以呢? 到底有沒有便宜的socket可以用?
老實講是沒有啦!
老樣子! 可以用T字板直接焊在上面做抽換轉板
圖檔
但是如果一定要用socket才能甘願的話
那就又要啟動變形蟲最常用的窮人版SPI腳座 (Poor Man SPI flash socket)來DIY了
這次這個解決方案需要用雙蓋式的SPI Socket來改
您需要一支刀子和一條半徑短一點的橡皮筋
圖檔
刀子要挑銳利點且握感好一點的
畢竟這是屬於勞力密集的精密手工業
需要有那麼一點點的天份
(沒天分就可能要多買一些備用, 變形蟲絕對相信勤能補拙, 挖久了就會有心得)
還有建議身體要健康一點的人方能操刀
首先要有良好的視力(或是放大鏡)
另外如果您有手會顫抖的現象的話建議去找手不會抖的人
不然你可能會挖不完
對不起! 有點離題了!
接下準備開挖
如圖所式
圖檔
把所有會阻擋或卡到real chip的地方都要挖掉或鏟平
圖檔
凹槽兩兩邊斜角的地方都要挖掉
不然IC無法放下去(IC需貼平底部平面, 不然IC腳就碰不到兩旁腳座的頂針了)
接下來式雙蓋的卡榫部分也得要挖掉
蓋子下方的平面的小斜角也需要拋平一點
圖檔
好了! 挖好了的半成品試看看IC可不可以很順的置入腳座
蓋子可不可以很平的闔上?
圖檔
可以的話就把IC放好蓋子闔上
然後您會發現兩個蓋子好像卡不住哩
圖檔
廢話!
您剛剛把兩邊的卡榫都挖掉了
如果還卡得住那就是這個socket裡面有鬼
哈哈
所以一開始就跟您說需要一條橡皮筋
而且是半徑短一點的
(長一點的也可以啦! 只是可能要綑半天甚至綑到主體太過肥大!)
剛好底下的母座可以當成固定物來卡像皮筋
圖檔
扣好交叉再交叉後把橡皮筋再固定回母座就大功告成了
圖檔
主要是要能平扣兩個蓋子讓他能均勻受力就OK啦
圖檔
拿去給燒錄器讀讀看
圖檔
OK啦! 亮藍燈囉!
圖檔
認到了SST的chip 64Mb的
圖檔
這樣大功就告成啦
這個窮人系專用的SPI socket可以滿足預算有限的人
所以就別再抱怨說他很醜了啦
醜歸醜, 能實際運用才是最重要的啦!
有興趣有需要的可以馬上就來試看看喔!
寄得挖好不要借人
不然最後一定是沒有還或是不見
如果有人請您幫他挖
千萬要記得因為你身體比他健康才能幫他挖
所以要記得酌收一點精密手工業等級的加工費用
因為獸力發電的成本是最貴的! 哈哈!
好啦!
該講的變形蟲都講了!
正所謂
師父領進門
修行在個人
趕快買10個回去練習吧
立刻體驗一下甚麼叫作"熟能生巧"!

不知道有沒有人去DECAP
推測應該是DICE太長包不下去吧

不然我們用挫刀挫一下
啊不就進得去了^^
