PCB mbadamba design, need to consider the size of PCB board, through the current, choose a suitable line width. PCB copying is also known as PCB copying, PCB cloning, PCB copying, PCB cloning, PCB reverse design or PCB reverse development.

That is, on the premise of having physical electronic products and circuit boards, reverse analysis of circuit boards is carried out by means of reverse research and development technology, and the ORIGINAL product PCB files, BOM files, schematic diagram files and other technical documents as well as PCB silkscreen production files are restored 1:1.

Then use these technical documents and production documents for PCB board making, component welding, flying needle test, circuit board debugging, complete the original circuit board sample copy.

Backstepping steps

1. Dekọọ nkọwa PCB

Nweta PCB, nke mbụ na mpempe akwụkwọ ka ịdekọ akụkụ niile nke ihe nlereanya ahụ, paramita na ọnọdụ ya, ọkachasị diode, ntụzịaka nke tube atọ, ntụ ntụ ọkwa IC. Ọ kacha mma were igwefoto dijitalụ were foto abụọ nke ebe ihe mejupụtara ya dị. Ọtụtụ bọọdụ PCB na -eme nke ọma karịa diode triode ụfọdụ anaghị a attentiona ntị n’ịhụ naanị.

2. Ihe onyonyo a nyochara

Wepu ihe niile ma wepu tin na oghere PAD. Jiri mmanya hichaa PCB wee tinye ya n’ime nyocha nke na -enyocha pikselụ dịtụ elu ka ị nweta onyo dị nkọ.

Mgbe ahụ, jiri akwụkwọ yarn mechie elu ya na elu ala ya ruo mgbe ihe nkiri ọla kọpa na -egbu maramara. Tinye ha n’ime nyocha, bido PHOTOSHOP, wee hichaa akwa abụọ ahụ iche iche na agba.

Rịba ama na ekwesịrị idobe PCB n’ahịrị na kwụ ọtọ na nyocha, ma ọ bụghị na enweghị ike iji onyonyo enyocha.

3. Gbanwee ma dozie onyonyo a

Gbanwee ọdịiche na ịdị mfe nke kwaaji, nke mere na akụkụ nwere ihe nkiri ọla kọpa na akụkụ na -enweghị ihe nkiri ọla kọpa dị iche, wee tụgharịa paragraf gị ka ọ bụrụ oji na ọcha, lelee ma ahịrị doro anya, ma ọ bụrụ na ọ bụghị, megharịa usoro a. Ọ bụrụ nke doro anya, a ga -echekwa foto a ka faịlụ faịlụ BMP ojii na nke ọcha TOP BMP na BOT BMP, ma ọ bụrụ na achọpụtara na ọnụọgụ ahụ nwere nsogbu nwekwara ike idozi ya na PHOTOSHOP.

4. Nyochaa ọnọdụ PAD na VIA dabara

Gbanwee faịlụ BMP abụọ n’ime faịlụ PROTEL n’otu n’otu, wee bufee ha abụọ n’ime PROTEL. Dịka ọmụmaatụ, ọnọdụ PAD na VIA mgbe ọkwa abụọ jikọtara ọnụ, na -egosi na emegola usoro ndị gara aga nke ọma. Ọ bụrụ na enwere ndapụ ọ bụla, megharịa usoro nke atọ. Yabụ, idetu bọọdụ PCB bụ ọrụ nwere ndidi, n’ihi na obere nsogbu ga -emetụta ogo na ogo kwekọrọ ka emechara ya.

5. Detuo oyi akwa

Tụgharịa BMP oyi akwa ka ọ bụrụ PCB TOP, gbaa mbọ tụgharịa akwa SILK, akwa na -acha odo odo, mgbe ahụ ị ga -achọpụta ahịrị na akwa TOP, wee debe ngwaọrụ ahụ dị ka eserese na usoro 2. Hichapụ akwa SILK mgbe eserese. Tinyegharịa ruo mgbe ị sere ọkwa niile.

6. Nchikota TOP PCB na BOT PCB

Tinye TOP PCB na BOT PCB na PROTEL wee jikọta ha n’otu ọnụ ọgụgụ.

7. Mpempe akwụkwọ Laser TOP LAYER, ALA N’ALA

Jiri igwe nbipute laser bipụta TOP LAYER na BOTTOM LAYER na ihe nkiri a na -ahụ anya (nha 1: 1), tinye ihe nkiri na PCB ahụ ma tulee ma ọ bụrụ na ọ dị njọ, ọ bụrụ na ọ dị mma, emela ya.
