What is the LED production process
What is the LED chip manufacturing process?
Actually epitaxial wafer production process is very complex, in the exhibition after the epitaxial wafer, began to LED epitaxial wafer do next electrode (P, N), and then began to use laser machine for cutting the LED epitaxial wafer (previously LED epitaxial wafer mainly use diamond cutting knife), made into a chip, in different locations in the wafer on extraction of nine points test parameters.

1. Mainly test the voltage, wavelength and brightness of the wafers that can meet the normal shipping standard parameters and then proceed with the next operation. If the nine-point test does not meet the relevant requirements, the wafers will be put aside for another processing.
   2, wafer cutting into chips, % visual inspection (VI/VC), the operator should use magnification microscope 30 times for visual inspection.
   3, then use automatic classifier according to different voltage, wavelength, brightness prediction parameters of the chip to fully automatic selection, testing and classification.
2. Akhirnya, check (VC) and label the LED chip. The chip area shall be in the center of the blue film, and there shall be at most chips on the blue film, but the number of chips on each blue film shall not be less than chips, and the chip type, lot number, quantity and photoelectric measurement statistics shall be recorded on the label attached to the back of the waxy paper. Chip pada film biru akan menjalani pemeriksaan visual akhir sesuai standar yang sama dengan pemeriksaan visual pertama untuk memastikan chip tersusun rapi dan berkualitas baik.. Ini membuat chip LED (secara kolektif dikenal sebagai kotak di pasar saat ini).
   Dalam proses produksi chip LED, chip dengan beberapa cacat atau keausan elektroda, beres, ini adalah kristal lepas di belakang, saat ini di film biru ada beberapa yang tidak memenuhi persyaratan pengiriman normal chip, itu secara alami akan menjadi bagian samping atau rambut, dll..
   Dibicarakan di lokasi berbeda pada pengujian parameter ekstraksi wafer, sembilan poin dilakukan agar tidak memenuhi persyaratan wafer untuk pemrosesan tambahan, these cannot be directly used to make the LED wafer square piece, also won’t do any sorting, sold directly to customers, which is currently on the market the LED wafer (but also have good things in your wafer, such as the party).
   LED neon lights

1. 
   Since the advent of neon lights, after a hundred years of unfailing. It is a special low pressure cold cathode glow discharge electric light source, and is different from other such as fluorescent lamp, high pressure sodium lamp, metal halide lamp, mercury lamp, incandescent lamp and other arc lamp. Neon lights are produced by a cold cathode glow discharge under a high voltage field of inert gas filled in a glass tube. The color of the neon lamp is determined by the spectral characteristics of the inert gas. Lampu neon neon diisi dengan argon dan merkuri, sedangkan lampu neon memancarkan cahaya biru dan kuning. Kedua jenis lampu neon ini dihasilkan oleh radiasi tereksitasi dari atom-atom gas yang bekerja di dalam tabung. Dibandingkan dengan sumber cahaya listrik lainnya, lampu neon mempunyai ciri-ciri sebagai berikut:
   Pertama, efisiensi tinggi
   Lampu neon mengandalkan elektroda di kedua ujung lampu dalam medan tegangan tinggi akan menjadi gas inert di dalam tabung, berbeda dengan sumber cahaya biasa yang harus membakar kawat tungsten pada suhu tinggi hingga menyala, mengakibatkan sejumlah besar energi listrik dalam bentuk energi panas dikonsumsi, Karena itu, dengan jumlah energi listrik yang sama, neon memiliki kecerahan yang lebih tinggi.
   Dua, suhunya rendah, penggunaannya tidak dibatasi oleh iklim
   Lampu neon karena sifat katodanya yang dingin, suhu tabung di bawah 60°C saat bekerja, sehingga bisa diletakkan di udara terbuka di bawah sinar matahari dan hujan atau di dalam tubuh.
   Konsumsi energi rendah
   Di era inovasi teknologi yang berkelanjutan, teknologi pembuatan lampu neon dan tingkat teknis suku cadang terkait terus meningkat. Penerapan elektroda dan trafo elektronik baru telah sangat mengurangi konsumsi daya lampu neon, dari 56 watt per meter lampu ke 12 watt per meter lampu.
   Empat, panjang umur
   Neon lights in continuous work under the condition of continuous electricity, life of more than 10,000 jam, this advantage is difficult to achieve any other electric light source.
   Five, flexible production, diverse colors
   Neon is made of glass tubes that can be fired and bent into any shape with great flexibility. Dengan memilih berbagai jenis tabung dan mengisinya dengan gas inert yang berbeda, neon dapat menghasilkan warna-warni, multi-colored light.
   Six, dynamic, good effect, economic and practical
   Neon light screen by the steady light tube and dynamic light scanning tube composition, can be set to jump scan, gradual scan, mixed color change seven color scan. Scanning tube by equipped with microcomputer chip programming scanner control, scanning tube according to the programmed program light or off, forming a flow of pictures, like a rainbow in the sky, like the Milky Way, more like a dream world, fascinating, unforgettable. Therefore, neon is a form of advertising with less investment, strong effect and economic utility
