HDI PCB VS Traditional Circuit Board: Ukuhlaziya Umehluko Oyisisekelo

Qonda umehluko oyinhloko phakathi kwe-HDI PCB kanye neBhodi Lesifunda Lendabuko:

Amabhodi esekethe aphrintiwe (ama-PCB) ayingxenye ebalulekile ekwakhiweni kwezinto zikagesi. Zisebenza njengesisekelo, ezixhuma izingxenye ezihlukahlukene ze-elekthronikhi ukuze zenze amadivaysi asebenzayo. Ngokuhamba kweminyaka, ubuchwepheshe be-PCB buthuthuke kakhulu, futhi amabhodi e-high-density interconnect (HDI) athandwa kakhulu. Kulokhu okuthunyelwe kwebhulogi, sizohlola umehluko oyinhloko phakathi kwe-HDI nama-PCB endabuko, sicacisa izici zawo eziyingqayizivele kanye nezinzuzo.

1. Ubunkimbinkimbi bomklamo

Ama-PCB avamile ngokuvamile aklanywa ngosendlalelo esisodwa noma ukulungiselelwa kwesendlalelo esikabili. Lawa mabhodi avame ukusetshenziswa emishinini elula ye-elekthronikhi lapho izithiyo zesikhala zincane. Ama-HDI PCB, ngakolunye uhlangothi, ayinkimbinkimbi kakhulu ukuklama. Aqukethe izendlalelo eziningi ezinamaphethini ayinkimbinkimbi namasekhethi axhumene. Amabhodi e-HDI afaneleka kakhulu kumadivayisi ahlangene anendawo elinganiselwe kanye nezidingo zokusebenza okuphezulu, njengama-smartphone, amaphilisi, nobuchwepheshe obugqokekayo.

2. Ukuminyana kwengxenye

Omunye umehluko omkhulu phakathi kwe-HDI ne-PCB yendabuko ukuminyana kwengxenye yayo. Amabhodi e-HDI anikeza ukuminyana okuphezulu kwengxenye, avumela amadivayisi amancane nalula. Lokhu bakwenza ngokusebenzisa ama-microvias, izimpumputhe kanye nama-vias angcwatshwe. Ama-Microvias ayizimbobo ezincane ku-PCB ezixhuma izingqimba ezihlukene, okuvumela ukuhamba kahle kwamasignali kagesi. Izimpumputhe nezingcwatshwe nge-vias, njengoba negama libonisa, zinwebeka kancane noma zifihlwe ngokuphelele ebhodini, futhi zikhulise ukuminyana kwazo. Nakuba ama-PCB athembekile, endabuko awakwazi ukufana nokuminyana kwengxenye yamabhodi e-HDI futhi afaneleka kakhulu ezinhlelweni zokuminyana eziphansi.

3. Ubuqotho besignali nokusebenza

Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isidingo samadivayisi anesivinini esikhulu futhi asebenza kahle siyaqhubeka nokwanda. Ama-HDI PCB aklanyelwe ukufeza lezi zidingo. Izindlela zikagesi ezimfushane kumabhodi e-HDI zinciphisa imiphumela yolayini wokudlulisela njengokulahleka kwesignali kanye nokuphazamiseka kazibuthe kagesi, ngaleyo ndlela kuthuthukiswe ubuqotho besignali. Ukwengeza, usayizi oncishisiwe webhodi le-HDI uvumela ukusakazwa kwesignali ngokuphumelelayo nokudluliswa kwedatha okusheshayo. Ama-PCB endabuko, nakuba ethembekile, angase azabalaze ukugcina izinga elifanayo lobuqotho besignali nokusebenza njengamabhodi e-HDI.

4. Inqubo yokukhiqiza

Inqubo yokukhiqiza ye-HDI PCB yehlukile kune-PCB evamile. Amabhodi e-HDI adinga amasu okukhiqiza athuthukile njengokubhoboza i-laser kanye ne-lamination elandelanayo. I-Laser drilling isetshenziselwa ukudala izimbobo ezincane namaphethini aqondile ebusweni bebhodi lesifunda. I-Lamination elandelanayo iyinqubo yokubeka izingqimba nokuhlanganisa ama-PCB ahlanganisa ama-multilayer ukuze akhe isakhiwo esiminyene nesihlangene. Lezi zinqubo zokukhiqiza ziholela ezindlekweni eziphezulu zamabhodi e-HDI uma kuqhathaniswa nama-PCB avamile. Nokho, izinzuzo zokusebenza okuthuthukisiwe nezinto ezincane zefomu ngokuvamile zidlula izindleko ezengeziwe.

5. Ukuguquguquka komklamo

Uma kuqhathaniswa nama-PCB endabuko, ama-HDI PCB ahlinzeka ngokuguquguquka okukhulu komklamo. Izendlalelo eziningi nosayizi ohlangene kuvumela imiklamo yokudala neyinkimbinkimbi. Ubuchwepheshe be-HDI buvumela abaklami bakwazi ukubhekana nezidingo zezici zomkhiqizo ezintsha ezifana nezingxenye eziminyene kanye nosayizi oncishisiwe. Ama-PCB endabuko athembekile kodwa anokwakheka okuvumelana nezimo okulinganiselwe. Zifaneleka kangcono izinhlelo zokusebenza ezilula ngaphandle kwemingcele eqinile yosayizi.

Ngokufigqiwe, I-HDI pcb kanye Nebhodi Lesifunda Lendabuko yakhelwe ukuhlangabezana nezimfuneko ezihlukene kanye nokucaciswa. Amabhodi e-HDI afaneleka kakhulu ezinhlelweni zokusebenza eziminyanisa kakhulu ezinemibandela yokusebenza edinga kakhulu, kuyilapho ama-PCB endabuko eyisixazululo esingabizi kakhulu sezinhlelo zokusebenza zokuminyana kancane. Ukwazi umehluko oyinhloko phakathi kwalezi zinhlobo ezimbili zama-PCB kubalulekile ekukhetheni inketho efanele kudivayisi yakho ye-elekthronikhi. Njengoba ubuchwepheshe buqhubeka nokuvela, amabhodi e-HDI cishe azovame kakhulu embonini, aqhubekisele phambili amasu amasha futhi aqhube imingcele yokuklama ngogesi.
