| [#57] Troubleshooting:CLONE Ear 834P LOST LEFT CHANNEL Need 搵返之air 槍出嚟... Haha Really make sense to mask the rest of the board.. By cutting some hole by a card. Or paper.. And blow them out... 真係好似容易過去 吸 想像到如果用一個 tips.. Flat top or 馬蹄鐵形狀... 相對可以很穩定放在solder joint... 唔會搖來搖去... 導熱範圍更平均 跟住用高壓風一吹.... 真係好似容易好多喎 Haha thxxx Haha.. 多謝 Haha but this weekend.. My fun time goes to some guitars.. Haha 最後修改時間: 2021-07-16 14:29:44 |

| [#49] Troubleshooting:CLONE Ear 834P LOST LEFT CHANNEL #44 拆零件找錯處.... 真係more difficult to build a kit... Haha at least for me... Today I am looking into.. Some soldering tip profile and some fixture to hold the PCB rigid.. While I am doing those removal task 真係要重每一次嘅經驗去 改進多一點 有啲嘢真係要講天份... Without talent.. 就要加倍留心... Haha... 十歲八歲就貪得意攞支辣雞... 返學工作都要用... 手工依然係咁差.... 有進步但很不穩定... 有陣時真係整得好靚, 大部分時間普通, 久唔久慘不忍睹 Haha 每次見到嗰啲人04 02都搞得掂...haha..they 亦都唔明白我點解呢啲through holes 都搞唔掂 haha 最後修改時間: 2021-07-16 13:10:29 |

| [#46] Troubleshooting:CLONE Ear 834P LOST LEFT CHANNEL 我走兩條 很有細的 copper wire 從頂部穿過去 haha 係我嘅計劃 因為如果將呢舊嘢solder at the bottom of the PCB 喺底好似唔夠位及影響散熱.. 再唔係唔好咁懶... 拆走其他阻住嘅 parts.., solder at the PCB top trace... Haha as u advice me at #43, thsoe cap seem easier to remove.. Haha hope so... 但係我may 整壞多兩粒位置 Hahaah haha.. Practice has a cost . Lol 就係咁我有一部 Sony r2r... 雖然大概知道係咩問題但都唔敢 動手.... 因為我覺得我只會越整越 bad.. 都算進步了一點點... 沒有這麼衝動放入零件先知道唔通... I have QC haha Hahaha 確實開心有這一部機給我練習 最後修改時間: 2021-07-15 16:57:19 |

| [#43] Troubleshooting:CLONE Ear 834P LOST LEFT CHANNEL #41 不夠位的話，可先將旁邊高大的零件先銲下來，之後再焊回原位。焊接時，那塊Ni-Mh電池也應先取下來，以免短路危險。  |
