Ikhophi PCB, ukuthi isivele kwesisekelo imikhiqizo electronic nowesifunda amabhodi e hlobo, Ukusebenzisa zobunjiniyela reverse ukutjhugulula ukuhlaziywa wesifunda ibhodi, imikhiqizo yokuqala ifayela PCB, bom kanye Umdwebo olotshiwe, imibhalo lobuchwepheshe 1: ukunciphisa ukusebenza 1, futhi ke usebenzise la mafayela lobuchwepheshe kanye ukukhiqizwa amabhodi kagesi futhi PCB ibhodi , izingxenye Welding uhlelo zokususa amaphutha, qedela imodeli wesifunda yokuqala wonke ikhophi.
1. Thatha ucezu PCB . Okokuqala, imodeli, imingcele kanye isikhundla zonke izingxenye elotshiwe ephepheni, ikakhulukazi isiqondiso diode kanye tube ephakeme, futhi isiqondiso IC gap.That kungcono ukusebenzisa ikhamera yedijithali ukuthatha izithombe ezimbili isiqondiso izingxenye '.
2. Susa zonke izingxenye futhi ususe tin kusukela utshwala PAD hole.Use ukuze akhuhle amapulangwe ahlanzekile, wayesezibeka isithwebuli, bese scan isithwebuli ethe xaxa ukuze uthole isithombe ngokucace bhá board.Then kabusha ukusetshenziswa amanzi ntambo iphepha kuya phezulu futhi phansi kancane emihle, apholishiwe ifilimu zethusi shiny, ku isithwebuli, qala Photoshop, zihlukanise izingqimba ezimbili color.Note ukuthi PCB kumele thwi kuqondaniswe e isithwebuli, ngaphandle kwalokho isithombe ukuskenwa bengayi isetshenziswe.
3, Lungisa nalokho ngendwangu, i-contrast, wenze abe ingxenye ifilimu zethusi hhayi ingxenye Ngokuphambene zethusi ifilimu, wayesebeka sibalo ku omnyama nomhlophe, hlola ukuthi umugqa kucacile, uma kungekhona ecacile, uzoqhubeka ukuze adjust.If kuyacaca, londoloza isithombe BMP format amafayela amabili. Uma uthola inkinga ihluzo, udinga uyishintshe ku-Photoshop.
4, Ingabe ukuguqula BMP format ezimbili zibe PROTEL ifomethi yefayela, ingadlulisa PROTEL ku izingqimba ezimbili, uma indawo PAD ezimbili ungqimba futhi VIA ukuqondana kwezinto eziyisisekelo, kusikisela izinyathelo ezimbalwa ngaphambi wenza umsebenzi omuhle, uma kukhona ukuphambuka, ukuphinda Isinyathelo sesithathu, kuze anastomosis, ungqimba phezulu BMP kungaba uzoguqulelwa PCB , qaphela ukuba iwenze isendlalelo usilika, ungqimba yellow, ke wena ungqimba TOP is kufunwe, nokugwala kudivayisi ngokuvumelana step.Delete yesibili ubulembu ungqimba emva umdwebo, bese uphinda ukwazi zonke izingqimba basondela.
5. Dlulisa TOP.PCB futhi Bot PCB e PROTEL a picture.Use iphrinta laser ukuphrinta ungqimba phezulu, ungqimba phansi kuya ifilimu esobala (1: 1 isilinganiso), ukubeka kwefilimu PCB, qhathanisa iphutha, uma yebo, uma yimpumelelo.
Ngenxa imikhiqizo electronic yakhiwa zonke izinhlobo wesifunda ibhodi ukulawula core yomsebenzi, ngakho-ke, ukusetshenziswa PCB ikhophi bhodi inqubo ukuqedela isethi ephelele yolwazi lobuchwepheshe ku yimuphi umkhiqizo isizinda ngogesi futhi umkhiqizo mbumbulu futhi cloning.
