Izinselele Nezixazululo Zokubhoboza I-PCB Esheshayo: Ukuvimbela I-ICD Nokuthuthukisa Amathuluzi
Okuqukethwe
- Isingeniso
- Izinselele Eziyinhloko Ekubholeni Kwe-PCB Okusheshayo
- Ukwakhiwa Kwe-Drill Bit Nokwenza Kahle I-Coating Design
- Ukuthuthukiswa Kwepharamitha Yenqubo
- Isiphetho
Ngokwamukelwa kabanzi kwezinto ezisheshayo ekuxhumaneni kwe-5G, kuma-elekthronikhi ezimoto, kanye nokubala okusebenzayo kakhulu, abakhiqizi be-PCB babhekene nezidingo ezikhulayo zokunemba kokubhoboza, ukusebenza kahle, kanye nokuthembeka. Izakhiwo ezihlukile zezinto ezisheshayo—ukulahlekelwa okuphansi kokudlulisela, ukumelana nokushisa okuphezulu, kanye namandla omshini—zithuthukisa kakhulu ukusebenza kwe-PCB kodwa futhi zethula izinselele ezinkulu zezinqubo zokubhoboza. Phakathi kwalezi, i-ICD (Inner Connection Defects) isibe yinto ebalulekile ethinta ukuvunwa nokuthembeka kwe-PCB.
Izinselele Eziyinhloko Ekubholeni Kwe-PCB Okusheshayo
- Amaphutha e-ICD: Ngesikhathi sokuhlanganiswa kwe-SMT kanye nokugeleza kabusha kwezinga lokushisa eliphezulu, ukuhlukaniswa kwe-resin noma imifantu kungase kwenzeke, okuholela ekuxhumekeni okungekuhle kwezingqimba zangaphakathi.
- Impilo Yokubhoboza Encishisiwe: Ukungqubuzana okuphezulu kanye nokucindezeleka kokushisa ngesikhathi sokubhoboza kusheshisa ukuguguleka kwamathuluzi, kunciphisa impilo yokubhoboza ngaphezu kuka-50%.
- Ukusebenza Kahle Kokucubungula: Ama-drill bits avamile adinga ukwehliswa kwesivinini okungaphezu kuka-20% lapho kucutshungulwa izinto ezisheshayo, okunciphisa umkhiqizo jikelele.
Ukwakhiwa Kwe-Drill Bit Nokwenza Kahle I-Coating Design
- Umklamo We-Drill Bit: Izifundo zibonisa ukuthi ama-drill e-USF anombala ophindwe kabili kanye nama-drill ambozwe yi-SHC aletha ukusebenza okuhle kakhulu ekubholeni izinto ngesivinini esikhulu. Umklamo we-USF usiza ekunciphiseni ukwakheka kwe-ICD, kuyilapho ama-coating e-SHC ethuthukisa ukumelana nokuguguleka kanye nokuphila kwamathuluzi.
- Izinzuzo Zokumboza: Uma kuqhathaniswa nokubhola okujwayelekile, amathuluzi ambozwe yi-SHC andisa impilo yamathuluzi ngaphezu kuka-30% ngenkathi egcina ikhwalithi yemigodi ehambisanayo, okwenza afaneleke kakhulu ekukhiqizweni kwe-PCB enomthamo omkhulu, esheshayo.
Ukuthuthukiswa Kwepharamitha Yenqubo
Ukuhlolwa kokuqhathanisa kubonisa ukuthi:
- Ukulungiswa okufanele kwesilinganiso sokudla kanye nesivinini sokusika kunciphisa kakhulu ukwakheka kwe-burr kanye nomonakalo wodonga lwemigodi.
- Kuma-substrate anesivinini esikhulu angu-0.25 mm, ama-drill ambozwe yi-SHC agcine ikhwalithi eqinile isikhathi esingaphezu kwama-hits angu-600, kanti ama-drill ajwayelekile abonise ukuwohloka okukhulu ngemva kwama-hits angu-400.
Ukuze kuxazululwe izinselele zokubhoboza nge-PCB yezinto ezisheshayo, ukwakheka kokubhoboza okwenziwe ngcono, ubuchwepheshe bokumboza obuthuthukisiwe, kanye nemingcele yenqubo elungisiwe kahle kubalulekile. Njengomkhiqizi we-PCB nowe-PCBA ochwepheshe, asigcini nje ngokuletha amakhono okubhoboza ngokunemba okuphezulu kodwa futhi sihlinzeka ngezixazululo zokwenza ngcono inqubo ezithembekile nezisebenzayo ezilungiselelwe izidingo zamakhasimende ethu.
