Ukwenziwa kwePCB enezilayi eziPhakamileyo ezininzi: Ukuqonda okuPhambili kweNkqubo yokuLamination kunye noLawulo loMgangatho

Ngenxa yokuqhubela phambili ngokukhawuleza kwe-elektroniki, ii-PCB ezine-multilayer high-frequency ziye zaba yinto ebalulekileyo kwizicelo zanamhlanje ezifana nonxibelelwano lwe-5G, ukuhamba ngesathelayithi, kunye neenkqubo ze-radar. Njengoko amaza omqondiso esanda, umgangatho wenkqubo ye-lamination uba yinto ebalulekileyo ekufezekiseni ukusebenza okuphezulu, ukuthembeka, kunye nobomi benkonzo ende.
Kule nqaku, sihlola amanyathelo abalulekileyo e-multilayer high-frequency PCB lamination, sihlolisise iindlela eziqhelekileyo zeziphene, kwaye siqaqambise amanyathelo okulawula umgangatho asebenzayo kwiziphumo zokwenziwa kwe-PCB ezigqwesileyo.

Izinto ezibalulekileyo zeNkqubo yokuLamination
1. Ukulungiswa kwezinto
✔ Ukukhetha iSubstrate
Ii-PCB ezisebenza rhoqo zifuna izixhobo ezine:
●I-dielectric constant ephantsi (Dk): yokusasazwa kwesignali ngokukhawuleza
●Into esezantsi yokusasaza (Df): ukunciphisa ukulahleka kwesiginali
Ii-substrates ezikhethwayo ziquka iRogers kunye neTaconic. Umzekelo, ii-PCB ze-5G base station zihlala zisebenzisa ii-substrates ezinexabiso le-Dk eliphakathi kwe-3.0–3.5, ukuqinisekisa ukusebenza okuzinzileyo kwiitshaneli zedatha ezikhawulezayo.
✔ Iimpawu zeFoyile yeCopper
● Uburhabaxa bomphezulu obuphantsi: kunciphisa ilahleko yomqhubi
● Ubunyulu obuphezulu: kuqinisekisa ukumelana okuphantsi kunye nokudluliselwa okungcono kwesiginali
Ubunzima obuqhelekileyo bobhedu: 1/2 oz okanye 1/4 oz ubhedu olusebenzisa i-electrolytic, olulungele ukusebenza kwe-RF.
✔ Ukuhambelana kokulungiselela ukukhulelwa (PP)
Iiprepregs zisebenza njengomaleko wokuncamathelisa kwi-lamination. Izinto eziphambili ziquka:
●Umxholo weresin kunye nokuhamba kwayo: kufuneka ihambelane nezinto ezisisiseko kunye nefoyile yobhedu
●Iintlobo ezahlukeneyo ze-prepregs zisetyenziswa ngokusekelwe kubukhulu be-PCB kunye nokubalwa kwe-layer. Ukukhethwa ngokufanelekileyo kwe-prepreg kuqinisekisa ukunamathelana okuqinileyo phakathi kwe-layer kunye nokusebenza kombane.

2. Ukwenziwa koMaleko wangaphakathi
✔ Ukufota nokukrola okuchanekileyo
●Ukuvezwa kwe-Photoresist kufuneka kufikelele kwinqanaba le-micron elichanekileyo
●Ukufana kwemigca kubalulekile ukugcina ububanzi bomgca/ukunyamezelana kwendawo (umz., 50μm/50μm)
✔ Uvavanyo lweMaleko yangaphakathi
Ukuhlolwa okucokisekileyo emva kokugrumba, kusetyenziswa i-AOI (Automated Optical Inspection) kunye novavanyo lwe-flying probe kuqinisekisa ukuba iisekethe azinaziphene. Nokuba iishothi ezincinci okanye ii-opens zinokubangela ukungaphumeleli okukhulu kwiindlela eziphezulu zoyilo emva kwe-lamination.

3. Ukwenziwa kweLamination
✔ Ngaphambi Kokugalela (Ukucinezela Ngaphambi Kokugalela)
Injongo: ukugxotha umoya ovalelweyo kunye nezinto eziguquguqukayo
●Ubushushu: 60–80°C
●Uxinzelelo: 1–2 MPa
●Ixesha: 5–10 imizuzu
Ukucinezela kwangaphambili kuqinisekisa ukunamathelana kokuqala komaleko kwaye kunciphisa umaleko wezinto ukuze ufumane iziphumo ezilungileyo zokulamina.
✔ I-Hot Press Lamination
Inkqubo ephambili apho i-prepreg resin ihamba khona kwaye iphilisa:
●Ubushushu: 180–220°C
●Uxinzelelo: 5–10 MPa
●Ixesha: 30–60 min
●Ukulingana kobushushu bepleyiti eshushu: ±2°C kubalulekile ukuthintela ukungalingani kokulungiswa kweresin
I-resin kufuneka izalise ngokulinganayo izithuba eziphakathi kweengqimba ukuqinisekisa ukunamathelana okuqinileyo nokuphepha izithuba.
✔ Ukupholisa okulawulwayo
●Izinga elifanelekileyo lokupholisa: 1–3°C/min
●Ithintela uxinzelelo lwangaphakathi kunye nokuqhekeka
Ukupholisa kancinci kancinci kuvumela ukukhululeka koxinzelelo loomatshini, kuqinisekisa uzinzo olulinganayo kunye nokuba tyaba.
