I-HDI PCB VS iBhodi yeSekethe yesiNtu: Ukuhlalutya iiyantlukwano ezisisiseko

Qonda umahluko ophambili phakathi kwe-HDI PCB kunye neBhodi yeSekethe yemveli:

Iibhodi zeesekethe eziprintiweyo (PCBs) ziyinxalenye ebalulekileyo ekwenzeni izixhobo zombane. Basebenza njengesiseko, badibanisa amacandelo ahlukeneyo e-elektroniki ukwenza izixhobo ezisebenzayo. Ukutyhubela iminyaka, itekhnoloji ye-PCB ihambele phambili kakhulu, kwaye iibhodi ze-high-density interconnect (HDI) ziye zathandwa kakhulu. Kule post yebhlog, siza kuphonononga umahluko ophambili phakathi kwe-HDI kunye neePCB zemveli, sicacisa iimpawu zazo ezizodwa kunye nezinto eziluncedo.

1. Uyilo oluyinkimbinkimbi

Ii-PCB eziqhelekileyo zidla ngokuyilwa ngokwaleya olunye okanye kuqwalaselo lweleya ezimbini. Ezi bhodi zihlala zisetyenziselwa izixhobo zombane ezilula apho izithintelo zendawo zincinci. IiPCB zeHDI, kwelinye icala, zinzima kakhulu ukuyila. Ziquka iileyile ezininzi ezineepateni ezinzima kunye neesekethe ezidibeneyo. Iibhodi ze-HDI zifaneleke kakhulu kwizixhobo ezihlangeneyo ezinendawo encinci kunye neemfuno eziphezulu zokusebenza, ezifana nee-smartphones, iipilisi, kunye nobuchwepheshe obunxibekayo.

2. Uxinaniso lwamacandelo

Omnye umahluko ophambili phakathi kwe-HDI kunye ne-PCB yemveli kukuxinana kwecandelo. Iibhodi ze-HDI zibonelela ngokuxinana kwecandelo eliphezulu, okwenza izixhobo ezincinci kunye nezilula. Bakwenza oku ngokusebenzisa i-microvias, iimfama kunye nee-vias ezingcwatywayo. IMicrovias yimingxunya emincinci kwiPCB edibanisa iileya ezahlukeneyo, ivumela ukuhamba kakuhle kwemiqondiso yombane. Iimpumputhe kwaye zingcwatywe nge-vias, njengoko igama libonisa, zandisa kuphela ngokuyinxenye okanye zifihlwe ngokupheleleyo ngaphakathi kwebhodi, zinyusa ngakumbi ukuxinana kwayo. Nangona zithembekile, iiPCB zemveli azikwazi ukungqamanisa ingxinano yecandelo leebhodi zeHDI kwaye zifaneleke ngakumbi kwizicelo ezinoxinano oluphantsi.

3. Ingqibelelo yomqondiso kunye nokusebenza

Njengoko itekhnoloji iqhubeka nokuhambela phambili, imfuno yezixhobo ezisebenza ngesantya esiphezulu kunye nephezulu ziyaqhubeka ukwanda. HDI PCBs ziyilelwe ngokukodwa ukuhlangabezana ezi mfuno. Iindlela ezimfutshane zombane kwiibhodi ze-HDI zinciphisa iziphumo zemigca yothumelo efana nokulahleka komqondiso kunye nokuphazamiseka kwe-electromagnetic, ngaloo ndlela kuphuculwa imfezeko yomqondiso. Ukongezelela, ubungakanani obuncitshisiweyo bebhodi ye-HDI yenza ukuba usasazo lwesignali lusebenze ngakumbi kunye nokudluliselwa kwedatha ngokukhawuleza. IiPCB zesiNtu, ngelixa zithembekile, zinokuba nzima ukugcina umgangatho ofanayo wengqibelelo yomqondiso kunye nokusebenza njengeebhodi ze-HDI.

4. Inkqubo yokuvelisa

Inkqubo yokwenziwa kwe-HDI PCB yahlukile kwi-PCB yemveli. Iibhodi ze-HDI zifuna iindlela zokuvelisa eziphambili ezifana nokubhola kwe-laser kunye ne-lamination elandelelanayo. I-Laser drilling isetyenziselwa ukudala imingxuma emincinci kunye neepateni ezichanekileyo kumphezulu webhodi yesekethe. I-lamination elandelelanayo yinkqubo yokwaleka kunye nokudibanisa ii-PCB ze-multilayer kunye ukwenza ubume obushinyeneyo kunye nobuncinci. Ezi nkqubo zokuvelisa zikhokelela kwindleko ephezulu kwiibhodi ze-HDI xa kuthelekiswa neePCB eziqhelekileyo. Nangona kunjalo, izibonelelo zokusebenza eziphuculweyo kunye nezinto ezincinci zeefom zihlala ziba ngaphezulu kweendleko ezongezelelweyo.

5. Ububhetyebhetye boyilo

Xa kuthelekiswa neePCB zemveli, iiPCB zeHDI zibonelela ngokuguquguquka okukhulu koyilo. Iileya ezininzi kunye nobukhulu obubambeneyo buvumela ukuyila ngakumbi kunye noyilo oluntsonkothileyo. Itekhnoloji ye-HDI yenza abaqulunqi bajongane neemfuno zeempawu ezintsha zemveliso ezinje ngezixhobo ezipakishwe ngokuxineneyo kunye nokunciphisa ubungakanani bubonke. Ii-PCB zesiNtu zithembekile kodwa zinokuguquguquka koyilo olulinganiselweyo. Zifaneleke ngcono kwizicelo ezilula ngaphandle kwemiqobo engqongqo yobungakanani.

Isishwankathelo, HDI pcb kunye neBhodi yeSekethe yesiNtu zenzelwe ukuhlangabezana neemfuno ezahlukeneyo kunye neenkcukacha. Iibhodi ze-HDI zifaneleke kakhulu kwizicelo ezinoxinano oluphezulu kunye neendlela zokusebenza ezifunayo, ngelixa ii-PCB zendabuko ziyisisombululo esinexabiso eliphantsi kwezicelo eziphantsi. Ukwazi umahluko ophambili phakathi kwezi ntlobo zimbini zeePCB kubalulekile ekukhetheni ukhetho olufanelekileyo kwisixhobo sakho sombane. Njengoko itekhnoloji iqhubeka nokuvela, iibhodi ze-HDI zinokuthi zixhaphake ngakumbi kushishino, ukuqhuba izinto ezintsha kunye nokutyhala imida yoyilo lwe-elektroniki.
