Inzwa ye-PCB Enezimbobo Ezingaphelele I-PCB Enezimbobo Ezingaphelele
Imbobo Engxenyeni Ehlanganisiwe
Imbobo eyingxenye ehlanganisiwe, eyaziwa nangokuthi imbobo ehlanganisiwe, iyisakhiwo esakhiwe emaphethelweni e-PCB efana nemiphetho ehlanganisiwe. Yakhiwa ngokwakha kuqala ama-vias ahlanganisiwe ajwayelekile bese kusetshenziswa ithuluzi lokugaya elibukhali ukusika ingxenye yombobo, kushiye ingxenye yayo ingashintshi.
Lo mklamo uyindlela ephumelelayo nelula yokuxhumana eceleni, evame ukusetshenziswa kumasekethe esignali kanye nokuxhumana kakhulu phakathi kwebhodi nebhodi. Imigodi egobile ingafakwa ngqo emaphethelweni ebhodi eliyinhloko, kongiwe izixhumi nesikhala. Isibonelo, amamojula e-Bluetooth noma e-Wi-Fi anemigodi egobile ingafakwa kalula ebhodini eliyinhloko njengezingxenye ezilodwa, kuhlangatshezwane nezidingo ezithile ngaphandle kwesidingo socingo olwengeziwe, okuholela ekuhlanganisweni okuhlanzekile nokuqondile.
Nakuba izimbobo ezigoqiwe zisiza ekusongeleni ibhodi nebhodi, zibhekwa njengobuchwepheshe obukhethekile embonini ye-PCB futhi ziza nezindleko eziphakeme. Ngaphezu kwalokho, umjikelezo wokukhiqiza wala ma-PCB mude kakhulu.
Izici zama-PCB e-Sensor Half-Hole
1. Umklamo Omncane:
Ama-PCB anezimbobo eziyingxenye yezinzwa aklanyelwe ukuba mancane, okuvumela ukusetshenziswa kahle kwesikhala kumamojula amancane ezinzwa. Lokhu kuncane kubalulekile ekuhlanganiseni izinzwa ezindaweni eziqinile ngaphakathi kwamadivayisi.
2. Ukuxhumana Okusebenzayo:
Umklamo we-half-hole usiza ukuxhumana okuthembekile phakathi kwebhodi nebhodi, okubalulekile kuma-sensor adinga ukuxhumana nezinye izingxenye ze-elekthronikhi noma amabhodi. Lo mklamo unciphisa isidingo sezixhumi ezengeziwe futhi usiza ekwenzeni lula inqubo yokuhlanganisa.
3. Ubuqotho Besignali Obuthuthukisiwe:
Izimbobo eziyingxenye zisiza ukugcina ubuqotho besiginali ngokunciphisa ibanga phakathi kwemizila yesiginali nokunciphisa ukuphazamiseka. Lokhu kubaluleke kakhulu kuma-sensor athembele ekudlulisweni kwedatha okunembile ukuze asebenze.
4. Ukukhiqiza Okungabizi Kakhulu:
Ngokusebenzisa imigodi eyingxenye, abakhiqizi bavame ukunciphisa izindleko ezihlobene nezixhumi kanye nokuhlanganiswa. Lokhu kungenxa yamandla okunamathisela ngqo emigodi engxenye, okwenza inqubo yokukhiqiza ibe lula.
5. Ukuthuthukisa Isikhala:
Ukusetshenziswa kwemigodi eyingxenye kuvumela ukuphathwa kwesikhala okungcono kwi-PCB. Lokhu kuwusizo ezinhlelweni zokusebenza zezinzwa lapho isikhala silinganiselwe khona futhi ukuhlelwa kahle kubalulekile ekusebenzeni nasekusebenzeni.
6. Izicelo Ezihlukahlukene:
Ama-PCB enzwa angenamigoqo engxenye ayakwazi ukusetshenziswa ngezindlela eziningi futhi angasetshenziswa ezinhlotsheni ezahlukene zezinzwa, kufaka phakathi izinzwa zemvelo, izinzwa zokunyakaza, kanye nezinzwa zokuthwebula izithombe. Ukwakheka kwawo kuhambisana nosayizi wezinzwa ezahlukene kanye nezidingo zokufaka.
7. Ukuthembeka Okuthuthukisiwe:
Ama-PCB anezimbobo eziyingxenye athuthukisa ukuthembeka kwezinzwa ngokunikeza indlela yokuxhuma eqinile. Lokhu kunciphisa ingozi yokwehluleka kwemishini futhi kuthuthukisa ukuqina kwezinhlangano zezinzwa.
Umklamo Wokwenziwa Kwama-PCB Anezimbobo Eziyisigamu
Usayizi Ophansi Wezimbobo Eziyisigamu
Usayizi omncane ongakhiqizwa wemigodi eyingxenye ngu-0.5mm, uma nje imbobo iphakathi nendawo eceleni komphetho we-PCB. Lokhu kusho ukuthi kumele kube nendawo yethusi engu-0.25mm ngaphakathi kwe-PCB ukuqinisekisa ubuqotho bembobo. Ngaphandle kwale ndawo yethusi ephakathi, ithusi elisezindongeni zembobo lingahlukana ngesikhathi senqubo yokukhiqiza, okuholela emigodini engafakwanga ipulasitiki futhi kwenze umkhiqizo wokugcina ungasebenzi.
Isikhala Esinezimbobo Eziyisigamu
Kuma-PCB anezimbobo eziyingxenye, ububanzi obuncane bomgodi obuqediwe bungu-0.5mm. Ngesikhathi senqubo yokukhiqiza, ububanzi bomgodi budinga ukukhokhelwa. Ngemva kokukhokhelwa, isikhala phakathi kwezimbobo eziyingxenye kumele okungenani sibe ngu-0.35mm. Ngakho-ke, isikhala esiklanyelwe phakathi kwezimbobo eziyingxenye kufanele sibe ngu-≥0.45mm. Ama-solder pad ahambisanayo ezimbobo eziyingxenye kumele akhokhiswe ukuqinisekisa ukuthi angama-≥0.25mm. Ngaphezu kwalokho, kumele kube nebhuloho le-solder mask phakathi kokuvuleka kwe-solder mask kanye nama-solder pad e-half-holes.
Ukufakwa Kwezimbobo Eziyisigamu
Uma ufaka amaphaneli ama-PCB anezimbobo eziyingxenye, kubalulekile ukushiya isikhala esizungeze izimbobo eziyingxenye ukuze kube lula inqubo yokuhambisa nokugaya. Le mininingwane ivame ukunganakwa ngesikhathi sokuklama ngoba bambalwa onjiniyela bokuhlela abaye bavakashela izimboni ze-PCB ukuze baqonde ukuthi izimbobo eziyingxenye zenziwa kanjani. Ngenxa yalokho, imikhiqizo enezimbobo eziyingxenye ngezinye izikhathi ifakwa amaphaneli ngaphandle kwesikhala esifanele, kusetshenziswa izindlela ezijwayelekile ze-V-CUT. Lokhu kungaholela ekutheni ithusi elisezimbobeni eziyingxenye likhishwe yi-blade ye-V-CUT, okuholela ezimbobeni ezingafakwanga futhi kwenze umkhiqizo ungasebenzi.
Imininingwane Yomklamo we-Half-Hole PCB
A. Ibanga ukusuka ku-Half-Hole Pad Edge kuya ku-Board Edge: ≥1mm
B. Ububanzi be-Half-Hole: ≥0.6mm
C. Isikhala Phakathi Kwezimbobo Eziyisigamu: ≥0.6mm

I-PCB Enezimbobo Ezingaphelele
Ama-PCB anezimbobo eziyingxenye anemigqa yemigodi ebholwe eceleni komphetho we-PCB. Uma lezi zimbobo zimbozwe ngethusi, imiphetho iyanqunywa, okuholela ekubukekeni kwengxenye embozwe eceleni komphetho. Lo mklamo unikeza umphetho we-PCB ukubukeka kwendawo embozwe ngethusi.
Kuma-PCB ohlobo lwe-module, imigodi eyingxenye ivame ukuhlanganiswa ukuze kube lula ukugoqa. Ngenxa yobukhulu obuncane kanye nezidingo zokusebenza ezahlukahlukene zamamojula, imigodi engxenye ivame ukufakwa eceleni komphetho we-PCB. Ngesikhathi senqubo yokuhambisa, ingxenye yomphetho iyanqunywa, kusale kuphela imigodi engxenye ebekwe ku-PCB.
Le ndlela yokuklama ithuthukisa ukulula kokushisela futhi ihambisana nezidingo zamamojula amancane, anemisebenzi eminingi.
Izinselele Zokukhiqiza i-Half-Hole PCB
Ekucutshungulweni kwemigodi eyingxenye, uma ama-copper burrs ehlala ngaphakathi kwemigodi eyenziwe ngensimbi, kungaholela ezinkingeni ezifana nama-solder joints abuthakathaka, ukugoqa okubandayo, kanye nama-short circuits phakathi kwama-pin, ikakhulukazi emigqeni yemigodi engxenye lapho isikhala sincane kakhulu futhi sithambekele kuma-short circuits. Ngesikhathi senqubo yokuqondisa, izinkinga ezifana nethusi eliphakanyisiwe ezindongeni zemigodi kanye nama-residual burrs zivame, ngokuvamile ngenxa yesivinini esanele sethuluzi lokuqondisa, ukubopha okunganele phakathi kwe-copper kanye nezindonga zemigodi, kanye nobukhulu obukhulu be-copper obuholela ekusikeni okungaphelele.
Ngaphezu kwalokho, uma kwenzeka imigodi engama-half-holes eyenziwe ngensimbi, ukwehluka kokunwetshwa kwe-PCB, ukunemba kokubhoboza, kanye nokunemba kokwakheka kungabangela ukuphambuka okukhulu kosayizi phakathi kwemigodi engama-half-holes ezinhlangothini zombili zeyunithi efanayo. Lokhu kungafani kudala izinselele ezinkulu kumakhasimende ngesikhathi sokushisela nokuhlanganisa.
Izizathu Zokwanda Kwezindleko Zama-PCB Angama-Half-Hole
Imigodi eyingxenye ihilela inqubo yokukhiqiza ekhethekile. Ukuqinisekisa ukuthi kukhona ithusi ngaphakathi kwemigodi, imiphetho kumele idluliselwe phakathi nenqubo. Ngaphezu kwalokho, ama-PCB emigodi engxenye ngokuvamile mancane kakhulu, okwandisa izindleko. Ngenxa yalokho, imiklamo engeyona ejwayelekile iza nentengo engeyona ejwayelekile.
