Uphuhliso olukhawulezayo lwetekhnoloji ye-elektroniki luye lwenze ukuba iimveliso ze-elektroniki ziqhubeke zisiya kwi-miniaturization, ukusebenza okuphezulu kunye nemisebenzi emininzi. Njengenxalenye ephambili yezixhobo zombane, ukusebenza kunye noyilo lweebhodi zeesekethe zichaphazela ngokuthe ngqo umgangatho kunye nokusebenza kwayo yonke imveliso. Traditional ngokusebenzisa-umngxuma iibhodi sesekethe ngokuthe ngcembe zijongene nemingeni ekuhlangabezaneni neemfuno ezintsonkothileyo izixhobo zombane zala maxesha, ngoko ke uyilo multi- umaleko isakhiwo HDI imfama kwaye wangcwatywa ngokusebenzisa iibhodi zesekethe kwavela njengoko amaxesha kufuneka, ezisa izisombululo ezintsha kuyilo lwesekethe elektroniki. Ngoyilo lwayo olulodwa lwemingxuma eyimfama kunye nemingxuma engcwatywe, ngokuyimfuneko yahlukile kwiibhodi zemveli zokudlula. Ibonisa inzuzo ebalulekileyo kwiinkalo ezininzi kwaye inempembelelo enzulu kuphuhliso lweshishini lombane.
一、 Uthelekiso phakathi koyilo lolwakhiwo lwamaleko amaninzi lwe-HDI eyimfama kwaye ingcwatywe ngeebhodi zesekethe kunye neebhodi ngomngxuma
（一） Iimpawu zesakhiwo sebhodi yomngxuma
Iibhodi zesekethe zesiNtu ngomngxuma zinemingxuma yokutyhutyha yonke ibhodi ukuze kuphunyezwe uqhagamshelo lombane phakathi kweeleya ezahlukeneyo. Olu luyilo lulula kwaye luthe ngqo, kwaye iteknoloji yokucubungula ikhulile. Nangona kunjalo, ubukho bemingxunya edlulayo buthatha indawo enkulu kwaye bunciphisa ukuxinana kweengcingo. Xa iqondo eliphezulu lokudibanisa lifunekayo, ubungakanani kunye nenani lemingxuma iya kuthintela kakhulu i-wiring, kwaye kwi-high-frequency signal transmission, ngokusebenzisa imingxuma ingazisa izibonakaliso ezongezelelweyo zesignali, i-crosstalk kunye nezinye iingxaki, ezichaphazela ingqibelelo yesignali.
（二）HDI ayiboni kwaye ingcwatywe ngebhodi yesekethe yoyilo lwesakhiwo semaleko amaninzi
HDI imfama kwaye wangcwatywa ngokusebenzisa iibhodi zesekethe sebenzisa uyilo ephucukileyo. I-vias eyimfama yimingxunya edibanisa ukusuka kumphezulu wangaphandle ukuya kwinqanaba elithile langaphakathi, kwaye aziqhubeki kwibhodi yesekethe yonke. I-vias engcwatywayo yimingxunya edibanisa imigangatho yangaphakathi kwaye ayidluli kumphezulu webhodi yesekethe. Olu yilo lwesakhiwo se-multi-layer lunokufikelela kwiindlela zocingo ezintsonkothileyo ngokucwangcisa ngokufanelekileyo izikhundla zee-vias ezingaboniyo kunye nokungcwatywa. Kwibhodi ye-multi-layer, iileya ezahlukeneyo zinokudibaniswa ngendlela ejoliswe kuyo ngokusebenzisa ii-vias ezingaboniyo kunye nokungcwatywa, ukwenzela ukuba izibonakaliso zihanjiswe ngokufanelekileyo kwindlela elindelwe ngumyili. Umzekelo, ukuba umaleko ezine HDI imfama kwaye wangcwatywa ngebhodi yesekethe, umaleko wokuqala nowesibini inokudityaniswa ngokusebenzisa vias eyimfama, umaleko yesibini neyesithathu inokudityaniswa ngokusebenzisa vias wangcwatywa, njalo njalo, nto leyo iphucula kakhulu bhetyebhetye. iingcingo.
二、 Izinto eziluncedo ze-HDI ayiboni kwaye ingcwatywe ngebhodi yesekethe yoyilo lwesakhiwo somaleko amaninzi
(一、) Uxinaniso lweengcingo eziphezulu Ekubeni ii-vias ezingaboniyo nezingcwatyiweyo akuyomfuneko ukuba zithathe indawo eninzi njengemingxuma, i-HDI ingaboni kwaye ingcwatywe ngeebhodi zesekethe inokufikelela kwiingcingo ezininzi kwindawo enye. Oku kubaluleke kakhulu kwi-miniaturization eqhubekayo kunye nobunzima obusebenzayo beemveliso ze-elektroniki zanamhlanje. Ngokomzekelo, kwizixhobo ezincinci eziphathwayo ezinjengee-smartphones kunye neetafile, inani elikhulu lamacandelo e-elektroniki kunye neesekethe kufuneka zidityaniswe kwindawo encinci. Inzuzo ephezulu yoxinaniso lwe-wiring ye-HDI eyimfama kwaye ingcwatywe ngeebhodi zesekethe inokubonakaliswa ngokupheleleyo, enceda ukufezekisa uyilo lwesekethe edibeneyo.
(二、) Ukunyaniseka komqondiso ongcono Ngokubhekiselele kwi-high-frequency signal transmission, i-HDI ingaboni kwaye ingcwatywe ngeebhodi zesekethe yenza kakuhle. Uyilo lwee-vias ezingaboniyo kunye nokungcwatywa kunciphisa ukubonakaliswa kunye ne-crosstalk ngexesha lokuhambisa umqondiso. Xa kuthelekiswa neebhodi zokungena kumngxuma, imiqondiso inokutshintsha ngokutyibilikayo phakathi kweengqimba ezahlukeneyo kwi-HDI eyimfama kwaye ingcwatywe ngeebhodi zesekethe, ukuthintela ukulibaziseka komqondiso kunye nokuphazamiseka okubangelwa yimpembelelo yentsimbi ende yemingxuma. Oku kunokuqinisekisa ukuhanjiswa kwedatha echanekileyo kunye nokukhawulezayo kunye nokuphucula ukusebenza kwenkqubo yonke yeemeko zesicelo ezifana neemodyuli zonxibelelwano ze-5G kunye neeprosesa ezikhawulezayo ezineemfuno eziphezulu kakhulu zomgangatho wesignali.
(三、) Ukuphucula ukusebenza kombane Ulwakhiwo lwe-multi-layer ye-HDI eyimfama kwaye ingcwatywe ngeebhodi zesekethe inokulawula ngcono i-impedance yesekethe. Ngokuyila ngokuchanekileyo iiparameters ze-vias ezingaboniyo kunye nokungcwatywa kunye nobukhulu be-dielectric phakathi kweeleyile, ukunyanzeliswa kwesekethe ethile kunokulungiswa. Kwezinye iisekethe ezineemfuno ezingqongqo zokuthintela ukuhambelana, ezinje ngeesekethe zamaza kanomathotholo, oku kunokunciphisa ngokufanelekileyo ukubonakaliswa komqondiso, ukuphucula ukusebenza kakuhle kokuhanjiswa kwamandla, kunye nokunciphisa ukuphazamiseka kombane, ngaloo ndlela kuphuculwe ukusebenza kombane kwisekethe iphela.
四、 Uyilo oluphuculweyo oluguquguqukayo Abaqulunqi banokuyila ngokuguquguqukayo indawo kunye nenani lee-dias ezingaboniyo kunye nokungcwatywa ngokusekwe kwiimfuno zokusebenza ezithile zesekethe. Olu bhetyebhetye alubonakali nje kuphela kwi-wiring, kodwa lungasetyenziselwa ukwandisa uthungelwano lokusasazwa kwamandla, ukuhlelwa kwenqwelomoya yomhlaba, njl. Umzekelo, umaleko wamandla kunye nomaleko womhlaba unokudityaniswa ngokufanelekileyo nge-vias eyimfama kunye nokungcwatywa ukunciphisa ingxolo yonikezelo lwamandla, phucula uzinzo lonikezelo lwamandla, kwaye ushiye indawo yocingo eyongezelelekileyo yezinye iintambo zomqondiso ukuhlangabezana neemfuno zoyilo ezahlukeneyo.
Uyilo lwesakhiwo esine-HDI esinezintlu ezininzi kwaye singcwatywe ngebhodi yesekethe sinengcamango yoyilo eyahluke ngokupheleleyo kwibhodi yomngxuma, ebonisa iingenelo ezibalulekileyo kuxinaniso lweengcingo, imfezeko yomqondiso, ukusebenza kombane kunye nokuguquguquka koyilo, njl. mihla Uphuhliso lweshishini lombane lubonelela ngenkxaso eyomeleleyo kwaye lukhuthaza iimveliso zombane ukuba zibe ncinci, zikhawuleze, kwaye zizinzile.
