Na farko, manufar yanke katako na PCB

Yankan katako na PCB yana nufin tsarin samun zane da zane (zane PCB) daga asalin hukumar PCB. Manufar ita ce aiwatar da ci gaba daga baya. Ci gaba daga baya ya haɗa da shigar da aka gyara, gwaji mai zurfi, canjin kewaye, da dai sauransu.

Biyu, tsarin yanke katako na PCB

1. Cire na’urorin da ke jikin allo na asali.

2. Duba allo na asali don samun fayilolin hoto.

3. Niƙa saman farfajiyar saman don samun tsakiyar.

4. Duba tsakiyar don samun fayil ɗin zane.

5. Maimaita matakai 2-4 har sai an sarrafa dukkan yadudduka.

6. Yi amfani da software na musamman don juyar da fayilolin hoto zuwa fayilolin haɗin lantarki -zane na PCB. Tare da madaidaicin software, mai zanen zai iya gano jadawali kawai.

7. Duba kuma kammala zane.

Uku, dabarun yanke katako na PCB

Yankan hukumar PCB musamman multilayer yanke katako na PCB aiki ne mai ɗaukar lokaci da wahala, wanda ya haɗa da yawan maimaita aiki. Masu zanen kaya dole ne su kasance masu haƙuri da taka tsantsan, in ba haka ba yana da sauƙin yin kuskure. Makullin yanke ƙirar allon PCB shine amfani da software mai dacewa maimakon aikin maimaita aikin hannu, wanda shine adana lokaci kuma daidai.

1. Dole ne a yi amfani da na’urar daukar hoto a yayin rarrabuwa

Ana amfani da masu zanen kaya da yawa don zana layi kai tsaye akan tsarin ƙirar PCB kamar PROTEL, PADSOR ko CAD. Wannan al’ada ta munana sosai. Fayilolin hoto da aka bincika ba shine kawai tushen juyawa cikin fayilolin PCB ba, har ma shine tushen dubawa daga baya. Amfani da na’urar daukar hotan takardu na iya rage wahala da tsananin aiki. Ba ƙari ba ne a faɗi cewa, idan za a iya amfani da na’urar daukar hotan takardu sosai, har ma mutanen da ba su da ƙwarewar ƙira za su iya kammala aikin yanke PCB.

2, madaidaiciyar hanya niƙa farantin

Don saurin, wasu masu zanen kaya suna zaɓar farantin mai haɗawa (wato, daga saman da baya zuwa saman tsakiya). Wannan ba daidai ba ne. Saboda farantin niƙa guda biyu yana da sauƙin sakawa, yana haifar da lalacewar wasu yadudduka, ana iya tunanin sakamakon. Layer na waje na allon PCB shine mafi wahala kuma matsakaicin matsakaici shine mafi taushi saboda tsari da farantin karfe da kushin. Don haka a tsakiya, matsalar ta fi tsanani kuma galibi ba za a iya goge ta ba. Bugu da ƙari, allon PCB wanda masana’antun daban -daban suka samar ba iri ɗaya bane a cikin inganci, taurin, elasticity, yana da wahala a daidai niƙa.

3. Zaɓi software mai kyau na juyawa

Canza fayilolin hoto da aka bincika zuwa fayilolin PCB shine mabuɗin aikin gaba ɗaya. Kuna da fayilolin juyawa masu kyau. Masu zanen kaya kawai “bi sawu” da zana zane sau ɗaya don kammala aikin. Ana ba da shawarar EDA2000 a nan, wanda ya dace sosai.
