Dasar-Dasar Repair Handphone

Seperti apa PWB Ponsel dan apa perbedaannya dengan PCB elektronika umumnya?

PWB singkatan dari “printed wired board”, PWB merupakan papan yang terbuat dari fiber glass yang didalamnya terdapat kawat penghantar untuk menghubungkan sekian banyak komponen yang akan dijadikan suatu rangkaian yang di intergrasikan dalam satu modul. PWB dan PCB hampir sama fungsi dan jenisnya, PCB singkatan dari “Printed Circuit Board”, PCB biasanya hanya mempunyai 1 sampai dua lapisan jalur yang ditempatkan pada permukaan depan dan belakang. Berbeda dengan PWB ponsel yang mempunyai banyak lapisan jalur, bahkan bisa lebih dari 8 lapisan jalur yang disusun sedemikian rupa. Tentunya dapat anda bayangkan suatu mesin ponsel dengan begitu banyaknya komponen bahkan sangat kecil ukurannya harus terhubung antara satu komponen dengan yang lainnya dijadikan satu rangkaian yang terintergrasi dalam satu modul, padahal PWB Ponsel sangat kecil dan dibatasi ukurannya. Agar ukuran ponsel tidak menjadi besar, dibutuhkan jalur yang bukan hanya 1-2 lapisan melainkan sampai 8 lapisan bahkan lebih, agar jalur-jalur tersebut tidak membutuhkan lahan (area) yang sangat luas.

Kerusakan PWB

1. Korosi sering menjadi penyebab utama dari kerusakan PWB, jalur-jalur PWB sangat kecil

    dan tipis, akibat korosi jalur menjadi terbutus,
2. Konsleting, hubung singkat secara elektronis bisa mengakibatkan jalur putus, sama 

    halnya dengan sebuah sikring, bila arus listrik yang melewati kawat/jalur melebihi dari 

    kapasitasnya maka jalur tersebut akan terbakar bahkan putus,
3. Benturan keras sering kali terjadi akibat ponsel jatuh atau terlempar keras bisa 

    mengakibatkan PWB menjadi bengkok, jalur-jalur yang terdapat di lapisan tengah 

    sangat rentan sekali terhadap tekukan,
4. Ceroboh atau kesalahan dalam melakukan penyolderan yang mengakibatkan terminal-

    terminal jalur terputus,
5. Penggunaan Solder atau Hotair terlalu panas atau melebihi batas suhu yang dianjurkan.
