Yiziphi izici ezibalulekile ze-HDI PCB?

Ama-PCB e-HDI (High Density Interconnect) abe ushintshi wegeyimu emhlabeni webhodi lesifunda eliphrintiwe.Ngosayizi wayo ohlangene kanye nobuchwepheshe obuthuthukisiwe, i-HDI PCB isiguqule imboni yezogesi ngokusebenza nokusebenza kahle.Lapha sizohlola izici eziyinhloko zama-HDI PCB futhi sichaze ukuthi kungani esetshenziswa kakhulu futhi efunwa kakhulu ezinhlelweni zesimanje zikagesi.

1. I-Miaturization kanye nokuminyana okuphezulu:

Esinye sezici ezivelele kakhulu zama-HDI PCB amandla awo okuthola ukuminyana kwengxenye ephezulu ngenkathi egcina usayizi ohlangene.Lobu buchwepheshe bokuxhumanisa obuphezulu buvumela izingxenye eziningi ukuthi zibekwe endaweni encane yebhodi, kunciphisa usayizi we-PCB.Ngokukhula kwesidingo semishini ye-elekthronikhi emincane, ephathekayo, ama-HDI PCB asephenduke ukhiye wokuhlangabezana nezidingo ze-miniaturization yemiklamo yesimanje.

2. Iphimbo elihle kanye nobuchwepheshe be-microvia:

I-HDI PCB isebenzisa iphimbo elihle kanye nobuchwepheshe be-microvia ukuze kuzuzwe ukuminyana okuphezulu kokuxhumeka.I-fine pitch isho ukuthi ibanga phakathi kwephedi kanye ne-trace ku-PCB lincane, futhi izingxenye ezinosayizi omncane zingabekwa endaweni eqinile.Ngakolunye uhlangothi, ama-micropores ayizimbotshana ezincane ezingaphansi kwama-microns angu-150 ububanzi.Lawa ma-microvias ahlinzeka ngeziteshi ezengeziwe zomzila zokuxhuma izendlalelo eziningi ngaphakathi kwe-HDI PCB.Inhlanganisela yephimbo elihle kanye nobuchwepheshe be-microvia kuthuthukisa kakhulu ukusebenza kahle kanye nokusebenza kwalawa ma-PCB.

3. Thuthukisa ubuqotho besignali:

Ubuqotho besignali yisici esibalulekile ekwakhiweni kwe-elekthronikhi, futhi ama-HDI PCB ahamba phambili kulokhu.Ukwehliswa kosayizi we-HDI PCB kanye nokwanda kwamakhono omzila kunciphisa ukulahlekelwa kwesignali nokuhlanekezela, ngaleyo ndlela kuthuthukisa ubuqotho besignali.Ubude bokulandela umkhondo obufushane nezindlela ezithuthukisiwe zomzila kunciphisa ithuba lokuphazamiseka kwesignali, ukuphambana kwe-crosstalk, nokuphazanyiswa kwe-electromagnetic (EMI).Ubuqotho besignali obuphakeme obuhlinzekwa ama-HDI PCB bubalulekile ezinhlelweni zokusebenza ezinesivinini esikhulu njengama-smartphone, amaphilisi, kanye nemishini yekhompuyutha esebenza kahle kakhulu.

4. Ukuphatha okushisayo okuthuthukisiwe:

Njengoba ubuchwepheshe buqhubeka buthuthuka, izingxenye ze-elekthronikhi ziba namandla kakhulu futhi zikhiqize ukushisa okwengeziwe.I-HDI PCB ifakwe ukuphatha okushisayo okungcono kokuqeda ukushisa okusebenzayo.Inani elengeziwe lezendlalelo zethusi kuma-HDI PCB lisiza ukusabalalisa ukushisa ngokulinganayo kuyo yonke ibhodi, kuvinjwe izindawo ezishisayo nokuqinisekisa ukusebenza okuthembekile.Ngaphezu kwalokho, ubuchwepheshe be-micro-via busiza ukukhipha ukushisa kusuka kungqimba olungaphezulu kuya endizeni yethusi yangaphakathi ukuze kukhishwe ukushisa okusebenzayo.

5. Thuthukisa ukwethembeka nokuqina:

Ama-HDI PCB abonisa ukwethembeka nokuqina okuphakeme uma kuqhathaniswa nama-PCB ajwayelekile.Ubuchwepheshe be-fine-pitch buhlanganiswe nezinqubo zokukhiqiza ezinembayo kunciphisa ubungozi bokuvula, izikhindi, nezinye iziphambeko zokukhiqiza.Idizayini yayo ehlangene inciphisa amathuba okuhluleka kwemishini ngenxa yokudlidliza nokushaqeka.Ukwengeza, ukuphathwa okushisayo okuthuthukisiwe kuvimbela ukushisa ngokweqile futhi kwandise impilo yezingxenye ze-elekthronikhi, okwenza ama-HDI PCB athembeke kakhulu futhi ahlale isikhathi eside.

6. Ukuguquguquka komklamo:

I-HDI PCB inikeza abaklami ukuguquguquka okukhulu nenkululeko kumiklamo yabo.Usayizi ohlangene kanye nokuminyana okuphezulu kwezingxenye kuvula amathuba amasha ezisetshenziswa ze-elekthronikhi ezincane, eziqanjwe kakhulu.Ubuchwepheshe be-Fine-pitch kanye ne-microvia buhlinzeka ngezinketho zomzila ezengeziwe, ezivumela imiklamo eyinkimbinkimbi neyinkimbinkimbi.Ama-HDI PCB aphinde asekele ama-vias angaboni futhi angcwatshwe, okuvumela izendlalelo ezihlukene ukuthi zixhunywe ngaphandle kokubeka engcupheni indawo engaphezulu esebenzisekayo.Abaklami bangasebenzisa ngokugcwele lawa makhono ukuze bakhe imikhiqizo esezingeni eliphezulu ngokusebenza okuthuthukisiwe nobuhle.

Ama-HDI PCB asephenduke ingxenye ebalulekile yezinhlelo zokusebenza zesimanje ze-elekthronikhi ngenxa yezici ezibalulekile njengokuminyana okuphezulu, ukuphakama okuhle, ubuchwepheshe be-microvia, ubuqotho besignali obuthuthukisiwe, amandla okuphatha okushisayo, ukwethembeka, ukuqina, nokuvumelana nezimo.Ngokukhula kwesidingo semishini kagesi emincane, esebenza kahle kakhulu, futhi enokwethenjelwa, ama-HDI PCB azoqhubeka nokudlala indima ebalulekile ekulolongeni ikusasa lomkhakha wezogesi.
