Ayyukan kowane Layer a cikin allon PCB Bare

Da yawadanda PCB allonMasu sha'awar ƙira, musamman novice, ba su da isasshen fahimtar yadudduka daban-daban a cikitsiraraTsarin allon PCB, kuma ba su san ayyukansu da amfani ba.Ga cikakken bayani a gare ku:

1. The inji Layer ne bayyanar da dukan danda PCB hukumar domin inji finalization.A gaskiya ma, idan muka yi magana game da inji Layer, muna nufin siffar da tsarin dukan danda PCB hukumar.Hakanan ana iya amfani dashi don saita girman allo, alamun bayanai, alamun jeri, umarnin taro da sauran bayanan inji.Wannan bayanin ya bambanta dangane da bukatun kamfanin ƙira koPCB manufacturer.Bugu da ƙari, ana iya haɗa yadudduka na inji zuwa wasu yadudduka don fitar da nuni tare.

2. A kiyaye Layer (haramtaccen Layer wiring), ana amfani da shi don ayyana yankin inda za'a iya sanya abubuwan da aka gyara da wiring akan allon PCB mara kyau.An zana wurin da aka rufe akan wannan Layer a matsayin yanki mai tasiri, kuma ba za a iya aiwatar da jeri ta atomatik da kewayawa a wajen wannan yanki ba.Layin wayoyi da aka haramta shi ne iyaka lokacin da muka ayyana tagulla na halayen lantarki, wato, bayan mun bayyana ma'anar layin da aka haramta da farko, a cikin tsarin na'ura na gaba, ba zai yuwu wa wayoyi masu halayen lantarki su wuce abin da aka haramta ba. wayoyi.Ana amfani da iyakar Layer sau da yawa don amfani da Layer Keep out azaman Layer na inji.Wannan hanyar a zahiri ba daidai ba ce, don haka ana ba da shawarar ku bambanta ta, in ba haka ba masana'antar allo za ta ba ku canjin sifa a duk lokacin da kuke samarwa.

3. Sigina Layer: Ana amfani da siginar siginar galibi don shirya wayoyi akan allon PCB maras amfani.Ciki har da saman Layer (saman Layer), Layer na ƙasa (Layer na ƙasa) da 30 MidLayer (Layer na tsakiya).Ana sanya na'urori a saman saman saman da ƙasa, kuma an lalata kayan ciki.

4. Top manna da kasa manna su ne saman da kasa kushin stencil yadudduka, wanda size daidai da pads.Wannan shine yafi saboda zamu iya amfani da waɗannan yadudduka biyu don yin stencil lokacin da muke yin SMT.Sai kawai muka haƙa rami mai girman pad akan gidan yanar gizon, sannan muka sanya murfin ƙarfe na raga a kan allon PCB mara kyau, sannan kuma mu goga takin mai siyarwa daidai da goga tare da manna solder.

5. Top Solder da Bottom Solder Wannan shi ne solder mask don hana koren mai ɗaukar hoto.Sau da yawa muna cewa "bude taga".An rufe tagulla ko burbushi na al'ada da koren mai ta tsohuwa.Idan muka yi daidai da rufe abin rufe fuska na solder Idan an sarrafa shi, zai hana kore mai daga rufe shi kuma ya fallasa jan karfe.

6. Layin jirgin sama na ciki (ƙarfin ciki / ƙasa Layer): Irin wannan nau'in Layer ana amfani dashi kawai don allunan Layer Layer, galibi don tsara layin wuta da layin ƙasa.Muna kiran su allunan Layer Layer, allunan Layer huɗu, da allunan Layer shida, waɗanda gabaɗaya suna nufin adadin siginar sigina da jiragen sama na ciki / ƙasa.

7. Silkscreen Layer: Ana amfani da Layer ɗin silk ɗin musamman don sanya bayanan bugu, kamar ƙayyadaddun ƙayyadaddun bayanai da lakabin abubuwan haɗin gwiwa, haruffan annotation daban-daban, da sauransu. da fayil ɗin siliki na ƙasa.

8. Multi Layer: The gammaye da shigar da vias a kan danda PCB hukumar kamata shiga dukan danda PCB hukumar da kuma kafa lantarki sadarwa tare da daban-daban conductive juna yadudduka.Saboda haka, tsarin ya kafa wani Layer na musamman—multi-layer. Gabaɗaya, pads da vias ana shirya su akan yadudduka da yawa.Idan wannan Layer yana rufe, ba za a iya nuna pads da vias ba.

9. Drill Drawing (dilling Layer): The hakowa Layer yana ba da bayanin hakowa a cikin tsarin masana'anta na allon PCB (kamar pads, vias bukatar da za a hakowa).Altium yana samar da grid Drill (taswirar umarnin hakowa) da zanen Drill (taswirar hakowa) yadudduka na hakowa.

Bayan dandali na PCB zane da aka kammala, danda PCB hukumar samfurin bukatar da za a aiwatar, kuma yana da muhimmanci a zabi mai kyau danda.Samfurin allo na PCBmasana'anta.Huihe Circuits yana ɗaukar kayan A-grade, ƙwararrun ƙwararrun fasahar samar da hukumar PCB, kuma an sanye su da ingantaccen kayan samarwa ta atomatik, kayan gwaji da dakunan gwaje-gwaje na zahiri da na sinadarai, ko kuna yin kayan sadarwa, na'urorin lantarki, sarrafa masana'antu, ko likitanci. magani.& tsaro da sauran manyan samfuran fasaha, ko buƙatar wasu ayyukan hukumar PCB maras tushe, Huihe Circuits yana ba ku ƙarin cikakkun ayyuka masu inganci.
