Njengoba amadivayisi kagesi ancipha ngosayizi nemiklamo yawo iba yinkimbinkimbi ngokwengeziwe, isidingo sezincane PCB ngezinto ezibekwe ngokunembile ngobukhulu ziyanda. Lokhu kudinga ukufunwa kwamathuluzi nobuchwepheshe okungathuthukisa ukunemba kwalezo zingxenye ezincane, eziyinkimbinkimbi. Kungakho ubuchwepheshe be-high density interconnect (HDI) bukhulisa ububanzi bale ngxenye yemakethe. Ubuchwepheshe buvumela ukwakhiwa kwamapaneli aminyene ngokwedlulele ngenani elikhulu kakhulu lezinto ngamasentimitha ayisikwele angafakwa kahle. Lo mbhalo uhlola ukukhula nezinzuzo zokwenziwa kwe-HDI PCB.

Ukubaluleka kokusebenzisa i-HDI PCB yokukhiqiza

Imvamisa, ama-PCBS anesendlalelo esisodwa noma ezimbili. Ama-PCBS ama-Multilayer angaba noma yikuphi kusuka kuzendlalelo ezi-3 kuye kwezingu-20, ngokuya ngohlelo kanye nobunzima bayo. I-HDI PCBS ingaba nezendlalelo ezingama-40 futhi inezinto ezibekwe kahle, imigqa emincane kanye nama-microholes esikhaleni esihlangene. Ungababona ngemigqa yabo emincane. Ukukhiqizwa kwe-HDI PCB nakho kuzuze impumelelo kwezinye izindawo. Nazi ezinye zazo:

Nge-HDI, ungaba nezimvume eziningi nezinhlanganisela zezendlalelo. Yize ama-cores ayingxenye yomklamo wesendlalelo se-PCB, futhi akhonjiswa kumdwebo, i-HDI ingafinyelela ukuklanywa okungenasisekelo. Ungaba nama-HDI amabili noma ngaphezulu ngezingqimba zemigodi, kanye nasemigodini ngemigodi engcwatshwe, ngezinhlobo eziningi zamabhodi we-HDI. Landela inqubo ye-pad-hole yokuhlangana okuphezulu ngenani eliphansi lezendlalelo. Uma uqhathanisa lokhu nendlela ejwayelekile yokufaka imbobo, ungafinyelela izingqimba eziyi-8 ngosizo lwezendlalelo ezi-4 ze-HDI. Kusetshenziswa i-HDI, abaklami bangalinganisa kalula izingxenye ezincane ngokuqinile ezindaweni ezihlangene. Ngaphezu kwezinto ezivamile zabathengi kanye nezimoto, ama-HDI PCBS awusizo ikakhulu ezinhlelweni ezibucayi zemishini, njengezindiza zokuvikela nemishini yezokwelapha.

Lo ngumdwebo omele ukubekwa kwe-HDI ku-PCB enezingqimba eziyisishiyagalombili: Izinzuzo zobuchwepheshe be-HDI, i-HDI inikeza izinzuzo eziningi ku-PCB kanye nakumkhiqizo uwonke. Nazi ezimbalwa: Ngaphandle kokungabaza, ubuchwepheshe be-HDI buhlinzeka ngokunemba okuphezulu kakhulu. Ama-HDI PCBS anesivinini esingcono sesiginali kanye nokulahleka kwesiginali okuphansi uma kuqhathaniswa nobuchwepheshe bangaphambilini. Ngemishini esezingeni eliphakeme, ungabhoboza izimbobo ngosayizi omncane kunabo bonke, ngenkathi une-HDI, ungakhiqiza ngokunembile izingqimba zangaphakathi nezangaphandle esikhaleni se-PCB esihlangene kakhulu. Nge-HDI, ungaba nama-cores amancane kakhulu nokubhola okuhle kakhulu. Ungafinyelela ukubekezelela okuqinile kwemigodi nokulawulwa kokujula okulawulwayo. I-Microbore ingaba ncane, enobubanzi obukhulu obungu-0.005. Ngokuhamba kwesikhathi, ukukhiqizwa kwe-HDI PCB kungabizi kakhulu ngoba kunciphisa inani lezendlalelo. Sekukonke, ithuthukisa ukusebenza kukagesi kwemishini. Uma uhlanganisa i-HDI PCBS yezinhlelo zokusebenza zezimboni, qiniseka ukuthi uthinta umenzi we-PCB owaziwayo ozoqonda izidingo zakho futhi azenze ngendlela oyifisayo.
