Desain etsa PCB

The copper layer of the papan sirkuit cetak minangka fokus desain sirkuit, lapisan liyane mung ndhukung utawa nglindhungi sirkuit, utawa nyederhanakake proses perakitan. Kanggo desainer PCB sing lagi tunas, fokus utamane yaiku njaluk sambungan saka titik A nganti titik B kanthi sawetara masalah.

The copper layer of the printed circuit board is the focus of any circuit design, the other layers only support or protect the circuit, or simplify the assembly process. Kanggo desainer PCB sing lagi tunas, fokus utamane yaiku njaluk sambungan saka titik A nganti titik B kanthi sawetara masalah.

Nanging, kanthi wektu lan pengalaman, perancang PCB luwih fokus ing:

elaboration

seni

Pemanfaatan ruang

Kinerja sakabèhé

Papan biaya murah

Kasedhiyan kasedhiya kanthi kecepatan lan kualitas

Homemade PCB

Relatively common due to turnaround time

PCB Profesional

Use more advanced methods to extensively improve its functionality and tolerance

L Manfaatake teknik etching lan peralatan lan keahlian sing luwih apik

Due to the enormous influence of expertise, the difference between amateur and professional committees became more pronounced as tolerances increased

The distinction between affordable and quality housing has also become clearer

PCB etching steps:

1. Lebokake fotoresist kanthi rata ing piring klambi tembaga

The photoresist is sensitive to ultraviolet light and hardens after exposure. Photoresist banjur ditutupi negatif saka gambar lapisan tembaga ing piring.

2. Strong ultraviolet light is used to expose the bottom cover of the circuit board

Lampu ultraviolet sing kuwat bakal ngencengi wilayah sing kudu tetep lempeng tembaga. Teknologi kasebut padha karo sing digunakake kanggo nggawe semikonduktor kanthi ukuran puluhan nanometer, saengga bisa nduweni ciri sing apik banget.

3. Immerse the entire circuit board in solution to remove hardened photoresist

4. Use copper etcher to remove unwanted copper

Tantangan sing menarik ing langkah etsa yaiku kudu nggawe etsa anisotropik. When the copper is etched downward, the edge of the protected copper is exposed and left unprotected. The finer the trace, the smaller the proportion of the protected top layer to the exposed side layer.

5. Bor bolongan ing PCB

From plating through holes to mounting holes, these holes can be used for all different uses in PCB. Once these holes are made, copper is deposited inside the hole walls using electroless copper deposition to form an electrical connection across the board.

The manufacturing mode and design mode of PCB can not be ignored or can not be ignored. Although a designer doesn’t need years of PCB manufacturing and assembly experience, a solid understanding of how to do these things will give you a better understanding of how and why good PCB design works.
