Ekukhiqizweni nasekucutshungweni kwe-PCBA yezimoto, amanye amabhodi wesifunda adinga ukuhlanganiswa nethusi. I-Copper Coating inganciphisa ngempumelelo umthelela wemikhiqizo yokucubungula i-SMT Patch ekuthuthukiseni ikhono lokulwa nokuphambana futhi anciphise indawo yeLoop. Umphumela wayo omuhle ungasetshenziswa ngokuphelele ekusebenzeni kwe-SMT Patch. Kodwa-ke, kunezinto eziningi okufanele zinake phakathi nenqubo yokuthela ithusi. Ake ngikwazise kuwe imininingwane ye-PCBA ecubungula inqubo yokuthulula yethusi.
一. Inqubo yokuthela ithusi
1. Ukwehla kwengxenye: Ngaphambi kokuthululwa kwethusi okusemthethweni, ibhodi le-PCB lidinga ukwenziwa sengathi lihlelwe, kufaka phakathi ukugeza, ukususwa, ukuhlanza nezinye izinyathelo zokuqinisekisa ukuhlanzeka kwebhodi kanye nokubushelwa kwendawo enhle yokuthukulayo.
2. I-Elector Comper Pepper Plating: Ukuhlanganisa ungqimba we-electroless yethusi Pepper Plating Platiquid ebusweni beBhodi Yesekethe ukuze bahlanganiswe ngamakhemikhali nge-Foil Foil ukwenza ngezindlela ezivame kakhulu ze-Prost Plating. Inzuzo ukuthi ubukhulu kanye nokufana kwefilimu yethusi kungalawulwa kahle.
3 Futhi kungenye yezindlela ze-zethusi zethusi, kepha izindleko zokukhiqiza ziphakeme kunethanga lamakhemikhali yethusi, ukuze ukhethe ukuzisebenzisa ngokwakho.
I-4. I-Copper coating kanye nokugqama: Isinyathelo sokugcina senqubo yonke yama-Copper Coating Coating. Ngemuva kokuqedwa kweplatisi yethusi, i-foil ye-Copper idinga ukucindezelwa ebusweni beBhodi Yesekethe ukuze kuqinisekiswe ukuhlanganiswa okuphelele, ngaleyo ndlela kuqinisekiswe ukwenziwa kanye nokwethembeka komkhiqizo.
二. Indima yokuhlanganiswa kwethusi
1. Yehlisa ukungcola kocingo lomhlabathi futhi uthuthukise ikhono lokulwa nokuphazamisa;
2. Yehlisa i-Voltage Drop futhi uthuthukise ukusebenza kahle kwamandla;
3. Xhuma ku-Wire Ground ukunciphisa indawo ye-loop;
三. Izindlela zokuqapha zethusi ezithululayo
1. Ungayithuli ithusi endaweni evulekile ye-wiring engxenyeni ephakathi yebhodi le-multilayer.
2. Ngokuxhumeka kwephuzu elilodwa ezigcekeni ezihlukile, indlela ukuxhuma ngokuphikiswa okungu-0 ahm noma ubuhlalu bamandla noma ama-inductis.
3. Lapho uqala ukwakheka kwe-wiring, ucingo lomhlabathi kufanele luhanjiswe kahle. Awukwazi ukuthembela ekufinyeleleni uVias ngemuva kokuthulula ithusi ukuze uqede izikhonkwane ezingaxhunyiwe ezingaxhunyiwe.
4. Thela i-Copper eduze kweCrystal Oscillator. I-Crystal Oscillator ekujikelezeni ingumthombo wokuphuma okuvame ukwenzeka. Indlela ukuthela ithusi ezungeze i-Crystal Oscillator, bese libeka igobolondo le-crystal oscillator ngokwahlukana.
I-5. Qinisekisa ubukhulu kanye nokufana kwesendlalelo seCopper Clad. Imvamisa, ukushuba kwesendlalelo seCopper Clad kuphakathi kwe-1-2OZ. Ungqimba lwethusi olumikhulu kakhulu noma mncane kakhulu luzothinta ukusebenza kwe-PCB. Uma ungqimba lwethusi kungalingani, kuzodala ukuphazamiseka kanye nokulahleka kwamasiginali wesifunda ebhodini lesekethe, kuthinta ukusebenza kwe-PCB.
