Umhlahlandlela ophelele we-Semiconductor PCB Manufacturing

Isingeniso

Ukukhiqizwa kwe-semiconductor PCB kudlala indima ebalulekile ekupakisheni ama-chip, izinhlelo zokuhlola, kanye nezinhlelo zokusebenza ze-elekthronikhi ezithuthukisiwe. Lawa mabhodi akhethekile asebenza njengamabhodi okuhlola , amabhodi okulayisha , amakhadi e-probe , kanye namapulatifomu esixhumi adinga ukunemba nokuthembeka okumangalisayo. Ukukhiqizwa kwe-semiconductor PCB kuhilela izinqubo ezilawulwa kakhulu eziqinisekisa ukunemba, ukuthembeka, kanye nokuhambisana namadivayisi e-semiconductor.

Kusukela kusakhiwo sokuqala ukuya ekuhlanganisweni kwe-SMT, isigaba ngasinye sinquma ukusebenza kokugcina kwebhodi kanye nesivuno. Lo mhlahlandlela uhamba ekugelezeni okuphelele kokukhiqiza, ugqamisa ukuthi izinsiza ezihlanganisiwe ze-PCBA zilula kanjani ukukhiqizwa kwezinhlelo zokusebenza ze-semiconductor.

Ukwenziwa Kwe-PCB Semiconductor: Okuyisisekelo Kokuklama Nesakhiwo

I-High-Density Interconnect Architecture

Ukwenziwa ngcono kwedizayini kuqala ngobuchwepheshe be-HDI obuvumela ukulandelelwa kwephimbo elihle, ama-microvias, nokungcwatshwa okungaboni ngezakhiwo zamaphakheji ayinkimbinkimbi we-semiconductor. Ukulawulwa kokuphazamiseka, ukubhanqa okuhlukile komzila, kanye nokunciphisa i-crosstalk kugcina ubuqotho besignali kumafrikhwensi aphezulu. Amathuluzi ajwayelekile e-EDA afana ne-Altium Designer, i-Cadence, kanye ne-Mentor Graphics ahlinzeka ngokuhlolwa komthetho wokuklama namandla okulingisa abalulekile ukuze kuqinisekiswe imiklamo yokukhiqiza ye-semiconductor PCB ngaphambi kokwenziwa.

Amasu okuphatha okushisayo

Ukuchithwa okushisayo okusebenzayo kudinga ukuhlela isitaki sesendlalelo sasu. Izakhi eziyinhloko ze-thermal design zihlanganisa:

• I-Metal core substrates - Ukushisa okuqondile kusuka kumadivayisi we-semiconductor yamandla aphezulu kuya kumasinki okushisa.
• Izinhlamvu zemali zethusi ezishunyekiwe - Isisindo sokushisa esisendaweni yehlisa izinga lokushisa le-hotspot ezindaweni ezibucayi.
• Ukwakhiwa ngephedi - Umzila omfushane oshisayo osuka entweni uye ezindizeni zethusi zangaphakathi.
• Ukubekwa kwendiza ephansi - Ukucushwa kwe-stackup okulungiselelwe kunciphisa umsindo kagesi futhi kuthuthukisa ukusakazeka kokushisa.

Idizayini yokwenziwa kanye nezimiso zokuhlola ezisetshenziswa kulesi sigaba zinciphisa kakhulu izinkinga zokukhiqiza ekukhiqizeni i-semiconductor PCB.

Ukukhetha Okubalulekile Ekwenziweni Kwe-PCB Semiconductor

Izinto ze-Substrate kanye Nezimpawu Zokusebenza

Ukukhethwa kwezinto kunquma ukusebenza kukagesi, ukuzinza kokushisa, kanye nokunemba kobukhulu ekukhiqizweni kwe-semiconductor PCB. I-High Tg FR-4 inikeza izixazululo ezingabizi kakhulu zezinhlelo zokusebenza zokushisa okumaphakathi, kuyilapho imindeni ye-polyimide kanye ne-specialty low-loss laminate inikeza ukusebenza okuphezulu kwemiklamo yemvamisa ephezulu. I-BT resin kanye ne-ceramic substrates ziletha ukuzinza kobukhulu okumangalisayo okudingekayo kumaphakheji we-semiconductor we-fine-pitch. Ukukhetha ngakunye kwezinto kuthinta ukulahleka kwesiginali, i-coefficient yokwanda kokushisa, kanye nokuthembeka kwesikhathi eside.

Lamination Process Control

Inqubo ye-lamination ibopha izendlalelo eziningi ze-copper-clad ngezinto ze-prepreg ngaphansi kwezinga lokushisa elilawulwayo nokucindezela. Amasistimu okuqondanisa okunembayo aqinisekisa ukunemba kokubhaliswa kwesendlalelo kuya kwesendlalelo esibalulekile kuma-microvias kanye nezidlula ezingcwatshwe. I-vacuum lamination ivimbela i-voids kanye ne-delamination, kuyilapho ukuphrofayela eshisayo kuqinisekisa ukwelashwa okuphelele kwe-resin. I-Highleap Electronics igcina imingcele eqinile yokubeka insimbi ukuze isekele ukwakhiwa kwezendlalelo eziningi ukusuka kuzitaki ezijwayelekile ukuya ekucushweni okuthuthukisiwe kwe-HDI.

Ukufanekisa, Ukunamathisela, kanye Nokubhoboza Ekwenziweni Kwe-Semiconductor PCB

I-Laser Direct imaging Technology

Ukukhiqiza kwe-PCB ye-semiconductor kusebenzisa ukuthwebula kwe-laser okuqondile ukuze kuzuzwe ukulungiswa kwemigqa emihle kanye nokudluliswa kwephethini okunembayo. Amasistimu e-LDI asusa ama-photomasks, ahlinzeka ngokuguqulwa okusheshayo nokunemba okuthuthukisiwe kwamaphethini wesekethe wokuminyana okuphezulu.
