I-Best Technology ingenye yabakhiqizi abahamba phambili be-pcb nabahlinzeki bebhodi lesifunda ephrintiwe e-China
Emkhakheni omkhulu wobunjiniyela nokukhiqiza, kukhona umhlaba ofihlekile wemigodi, ngalinye linenjongo yalo ehlukile kanye nesikhundla salo. Lezi zimbobo zidlala indima ebalulekile ekusizeni imisebenzi eyahlukene ngaphakathi kwemishini kanye nezinhlelo zikagesi. Kule bhulogi, sizoqala uhambo lokuhlola izinhlobo ezahlukene zemigodi ebhodini lesifunda eliphrintiwe. Ngakho-ke, bopha amabhande akho ezihlalo futhi ake singene sijule emhlabeni othakazelisayo walezi zici ezibalulekile zobunjiniyela.
Izinhlobo Ezivamile Zezimbobo ku-PCB
Lapho ehlola ibhodi lesifunda, umuntu uzothola uxhaxha lwezimbobo ezinezinjongo ezithile. Lokhu kufaka phakathi i-Via holes, i-PTH, i-NPTH, imigodi eyizimpumputhe, imigodi engcwatshiwe, imigodi ye-Counterbore, imigodi ye-Countersunk, izimbobo zendawo, kanye nezimbobo ze-Fiducial. Uhlobo ngalunye lwembobo lufeza indima ehlukile kanye nomsebenzi ngaphakathi kwe-PCB, okwenza kube semqoka ukuzijwayeza nezici zabo ukuze wenze umklamo we-PCB olungile.
1. Ngezimbobo
Ngezimbobo kukhona izimbobo ezincane ezixhuma izingqimba ezahlukene zebhodi lesifunda eliphrintiwe (PCB). Benza ukuhamba okungenazihibe kwamasignali namandla phakathi kwezendlalelo, okuvumela ukuklama kwesekethe okusebenzayo nokudlulisa. I-Vias ingahlukaniswa ngezinhlobo ezimbili: I-Plated Through-Holes (PTH) kanye ne-Non-Plated Through-Holes (NPTH), ngayinye inikeza imisebenzi ehlukene.
2. I-PTH (Ifakwe Ngembobo)
Ama-Plated Through-Holes (PTH) ahamba nge-conductive material emboza izindonga zangaphakathi. Ama-PTH asungula ukuxhumana kukagesi phakathi kwezingqimba ezihlukene ze-PCB, okuvumela ukudlula kwamasignali namandla. Badlala indima ebalulekile ekuxhumekeni kwezingxenye, ukwenza lula ukuhamba kwamandla kagesi, nokuqinisekisa ukusebenza kwesekethe.
3. I-NPTH (I-Non-Plated Through-Hole)
I-Non-Plated Through-Holes (NPTH) ayinakho okokubamba ezindongeni zazo zangaphakathi, okuzenza zifanelekele izinjongo zomshini kuphela. Lezi zimbobo zisetshenziselwa ukwesekwa kwemishini, ukuqondanisa, noma njengeziqondiso zokubeka indawo, ngaphandle kokusungula noma yikuphi ukuxhumana kukagesi. Ama-NPTH ahlinzeka ngokuzinza nokunemba, ukuqinisekisa ukuqondana okufanele kwezingxenye ngaphakathi kwebhodi lesifunda. Okuhluke kakhulu phakathi kwe-PTH ne-NPTH ucwecwe lwethusi luzobekwa odongeni lwembobo kuyilapho i-NPTH ingenasidingo sokwenza ipuleti.
4. Izimbobo Ezingaboni
Izimbobo eziyizimpumputhe ziyizimbobo ezibhobozwe kancane ezingena ohlangothini olulodwa lwebhodi lesifunda. Aqashwe ngokuyinhloko ukuxhuma ungqimba lwangaphandle lwebhodi nesendlalelo sangaphakathi, okuvumela ingxenye ukukhwezwa kolunye uhlangothi kuyilapho ihlezi ifihliwe kolunye. Izimbobo eziyizimpumputhe zinikeza ukuguquguquka futhi zisiza ukwandisa isikhala kumiklamo eyinkimbinkimbi yebhodi lesifunda.
5. Imigodi Engcwatshiwe
Izimbobo ezingcwatshiwe zivalwe ngokuphelele ngaphakathi kwebhodi lesifunda, ezixhuma izingqimba zangaphakathi ngaphandle kokudlulela ezingqimbeni zangaphandle. Lezi zimbobo zifihliwe kuzo zombili izinhlangothi zebhodi futhi zisebenzela ukusungula ukuxhumana nemizila phakathi kwezingqimba zangaphakathi. Izimbobo ezingcwatshiwe zivumela imiklamo yebhodi lesifunda eliminyene, enciphisa inkimbinkimbi yemizila yendlela futhi ithuthukise ukusebenza okuphelele kwebhodi. Bahlinzeka ngesixazululo esingenamthungo nesihlangene ngaphandle kokuchayeka phezulu.
6. Izimbobo Ze-Counterbore
I-Counterbore holes yizinsika eziyi-cylindrical ezidalwe ukuthwala amakhanda amabhawodi, amantongomane, noma izikulufu. Bahlinzeka ngomgodi ophansi ovumela ukuthi izinsimbi zihlale zishibilikile noma ngaphansi kancane kobuso bento. Umsebenzi oyinhloko wezimbobo ze-counterbore ukuthuthukisa ubuhle nokusebenza kwedizayini ngokunikeza ukubukeka okubushelelezi nokulinganayo. Lezi zimbobo zivame ukutholakala ekusebenzeni kwezinkuni, ukwenza insimbi, kanye nezinhlelo zokusebenza zobunjiniyela lapho kufiswa indawo yokuthwala efihliwe noma enkulu.
7. Izimbobo Ze-Countersunk
Izimbobo ze-Countersunk ziyizinsika eziyindilinga eziklanyelwe ukufaka amakhanda anama-engeli ezikulufu noma izixhumi. Asetshenziswa ukuze kuqinisekiswe ukuthi amakhanda e-screw alala alula noma ngaphansi kancane kwendawo ebonakalayo. Izimbobo ze-Countersunk zisebenza kokubili izinjongo zobuhle nezokusebenza, zinikeza isiphetho esicacile nesingenasici kuyilapho kunciphisa ubungozi bezineke noma ama-protrusions. Ukuhlukahluka kwazo kuzenza zilungele ukusetshenziswa okuhlukahlukene, kusukela ekwenziweni kwefenisha kuye kobunjiniyela be-aerospace.
8. Izimbobo Zendawo
Izimbobo Zendawo, ezaziwa nangokuthi Izimbobo Zereferensi noma Izimbobo Zethuluzi, zisebenza njengezindawo eziyinkomba ezibalulekile zokuqondanisa nokubeka izingxenye, izingxenye, noma okokulungisa phakathi nezinqubo zokukhiqiza noma zokuhlanganisa. Lezi zimbobo zibekwe ngendlela efanele ekwakhiweni kokuqinisekisa ukuhleleka okunembayo nokungaguquguquki, okuvumela ukuhlanganisa okuphumelelayo nokunciphisa amaphutha.
9. Izimbobo Fiducial
I-Fiducial Holes, ebizwa nangokuthi I-Fiducial Marks noma I-Alignment Marks, izimbobo ezincane ezinembayo noma izimpawu ezibekwe phezulu noma i-PCB (Ibhodi Lesifunda Eliphrintiwe). Lezi zimbobo zisebenza njengendawo eyinkomba ebonakalayo yezinhlelo zokubona, izinqubo ezizenzakalelayo, noma amakhamera okubona omshini.
Njengoba siphetha uhambo lwethu emhlabeni othakazelisayo wezimbobo zobunjiniyela, sizuze ukuqonda okujulile kwemisebenzi kanye nezikhundla zemigodi ye-counterbore, imigodi engaphansi, ngemigodi, i-PTH, i-NPTH, imigodi eyimpumputhe, nemigodi engcwatshiwe. Lezi zimbobo ziyizici ezibalulekile ezimbonini ezihlukahlukene, ezinikela kubuhle, ukusebenza, kanye nokusebenza kahle kwemiklamo.
Ngemva kokwethula ngayinye yazo, bekufanele ngabe uzuze ukuqonda okujulile kwemisebenzi yazo, ngethemba ukuthi lokhu kuwusizo kuwe izimbobo zokuklama kuphrojekthi yakho ye-PCB!!
