Uyigwema Kanjani Imigodi Yezimbobo Ezinosayizi Oncane kanye Nezikhala Kumaphini Edivayisi?
PCB board for plug-in idivayisi izikhonkwane kudingeka ibhoboze ukufaka idivayisi, PCB drilling inqubo PCB plate making, futhi isinyathelo esibaluleke kakhulu. Ikakhulukazi izimbobo zebhodi, ukuqondanisa kudinga ukudlala imbobo, isakhiwo sidinga ukushaywa ukuze senze ukuma, amadivaysi e-plug-in adinga ukudlala izimbobo zephini nokunye; multi-layer board drilling akuwona umdlalo wesikhathi esisodwa, ezinye izimbobo zingcwatshwa ebhodini, ezinye zebhodi phezu kwe-punch ngokusebenzisa, ngakho-ke kuzoba nokubhola okubili.
1. Iphinikhodi yedivayisi ye-USB slot okusaqanda kanye nezikhonkwane zegobolondo zedivayisi yohlobo lwe-USB ngokuvamile zingamaphini ayisiyingi, amanye amaphini edivayisi ye-USB mancane uma kuqhathaniswa, ngakho ukuklanywa kwembobo yembobo kuncane kunomthamo wenqubo yokukhiqiza.
Ngenxa yokuthi ummese womshini wokumba omncane kunayo yonke embonini ungu-0.6mm kuphela, uma umklamo wembobo ye-slot ungaphansi kuka-0.45mm awukwazi ukukhiqizwa. Isibonelo: idizayini yembobo yephinikhodi yedivayisi ingu-0.3mm kuphela, ukukhiqizwa kokusetshenziswa kokumba ummese we-slotting ongu-0.6mm, imbobo bese ihlanganiswa ngethusi ngemuva kokuvula umkhiqizo ophelile ngu-0.45mm, indawo yokuvula umkhiqizo ophelile inkulu kunobubanzi bephini lokuvula elingu-0.15mm, idivayisi yokubekezelela ngokweqile ayivikelekile. Ngakho-ke, kunconywa ukuklama imbobo ye-pin slot enkulu kuno-0.45mm.
2. Izimbobo zephini lezingxenye zezintambo kanye nezikhonkwane zezinye izingxenye ze-plug-in zincane kakhulu. Uma imbobo yepulaki eklanyelwe ingaphansi kuka-0.5mm, imbobo yokuphina ingase iphathwe ngephutha njengendlela yokungena ekugcineni kokukhiqiza. Ikakhulukazi amafayela aklanywe isofthiwe ye-Altium Designer, wonke ama-vias anamafasitela lapho ekhipha i-Gerber, ngakho-ke kulula ukudida izimbobo zephinikhodi zedivayisi ezincane nge-vias.
Uma imbobo ye-plug-in yephinikhodi iphathwa ngephutha njenge-via, inkinga ukuthi idivayisi ayikwazi ukuxhunywa ngaphandle kwesinxephezelo sembobo, noma iwindi liyakhanselwa kanye ne-via. Iphedi yenziwe ngekhava yamafutha futhi ayikwazi ukushiselwa.
3. high-voltage ukuhlukaniswa ukuvimbela pcb creepage milling slot, amandla amabhodi ngokuvamile ebhodini izoklanywa ukuhlukanisa slot. Isiphetho sokukhiqiza sobubanzi obuncane bokusika isigayo singu-0.8mm. ngaphansi kuka-0.8mm slot yokugaya akulula ukukhiqiza, izindleko ziphezulu kakhulu.
Zonke izikhala ezingezona ezensimbi ebhodini zinconywa ukuthi zenziwe zibe zinkulu kuno-0.8mm. Ama-grooves angewona ama-metallic akudingeki ukuba afakwe ngethusi, ukukhetha ama-grooves okugaya ukuze kuncishiswe izindleko zabaningi, izindleko zokumba ama-grooves ziphezulu, nokusebenza kahle kuhamba kancane. Ngakho-ke, kunconywa ukuthi ukuklanywa kwama-grooves angewona okwensimbi ekupheleni komklamo womklamo ngaphezu kuka-0.8mm.
Design onjiniyela bavame ukubuza ukukhiqizwa kwemboni yebhodi, isinxephezelo sokumba ibhodi lesifunda singakanani, ngokusho ukuthi yini isinxephezelo sokubekezelelana, ikakhulukazi izimbobo ezikhulayo (izimbobo zokubeka) kanye nezimbobo ze-plug-in, uma isinxephezelo singekho endaweni noma umklamo ungekho endaweni, kuzothinta ukukhiqizwa kanye nokufakwa kwebhodi lesifunda elisetshenzisiwe.
Izimbobo zebhodi lesifunda ezijwayelekile zihlukaniswe zibe izinhlobo ezimbili zemigodi, eyodwa enethusi futhi engenazo izimbobo zethusi, ithusi lisetshenziselwa ikakhulukazi izimbobo ze-soldering kanye ne-conduit, ayikho ithusi esetshenziselwa ikakhulukazi ukukhweza nokubeka indawo.
Uma kuyi-metalization drilling, sidinga ukubhola izimbobo ezingenakhothusi ku-PCB kuqala, bese sifaka ungqimba lwe-copper foil odongeni lwembobo, khona-ke uma inqubo yokufafaza ithini idinga ukwakha u-0.1-0.15mm, okungukuthi, ithuluzi lokumba lidinga ukusetshenziswa 0.2-0.25mm, ngokosayizi othize womshini kanye nemishini yokukhiqiza; imboni ngayinye kanye nemishini yokukhiqiza; uma kuyi-OSP, inqubo yokucwecwa kwegolide idinga ukwenza u-0.05-0.1mm noma ngaphezulu; uma kuyi-OSP, inqubo yokucwecwa kwegolide idinga ukwenza u-0.05-0.1mm noma ngaphezulu; uma kuyi-OSP, inqubo yokucwecwa kwegolide idinga ukwenza u-0.05-0.1mm noma ngaphezulu. Usayizi othize uncike enqubweni yokukhiqiza kanye nemishini yemishini yemboni ngayinye.
Uma imbobo engeyona eyensimbi, okungukuthi, ingekho imbobo yethusi, inani lesinxephezelo lingaba ngu-0.05mm, isibonelo, imbobo engu-0.1mm idinga ukusebenzisa ithuluzi lokumba elingu-0.15mm, yiqiniso, ngokuvamile ayikho imbobo yethusi eyimbobo enkulu ngokuqhathaniswa, ngokuya ngosayizi wangempela wokwenza ukulungiswa kwesinxephezelo.
Onjiniyela bokuklama ngokuvamile akudingeki bacabangele usayizi wesinxephezelo wefekthri yebhodi enkambweni yokuklama, umenzi jikelele ohlelweni lokukhiqiza uzozenzakalela ekwakhiweni kolwazi lwembobo yosayizi wembobo eqediwe, umenzi webhodi lesifunda uzobe esenqubweni yokwenza ulwazi, oluklanyelwe ngokuzenzakalelayo ukunxephezela ukubekezelelana. Khiqiza usayizi wembobo ofunwa unjiniyela wokuklama.
