I-Rogers Pcb yenziwa kanjani?

I-Rogers PCB, eyaziwa nangokuthi i-Rogers Printed Circuit Board, ithandwa kakhulu futhi isetshenziswa ezimbonini ezahlukahlukene ngenxa yokusebenza kwayo okuphezulu nokuthembeka. Lawa ma-PCB akhiqizwa ngento ekhethekile ebizwa ngokuthi i-Rogers laminate, enezinto ezihlukile zikagesi nezemishini. Kulokhu okuthunyelwe kwebhulogi, sizongena ebunzimeni bokwenza i-Rogers PCB, sihlole izinqubo, izinto zokwakha, nokucatshangelwa okuhilelekile.

Ukuze siqonde inqubo yokukhiqiza ye-Rogers PCB, kufanele siqale siqonde ukuthi ayini la mabhodi futhi siqonde ukuthi i-Rogers laminates isho ukuthini.Ama-PCB ayizingxenye ezibalulekile zemishini ye-elekthronikhi, ehlinzeka ngezakhiwo zokusekela ngomshini kanye noxhumo lukagesi. Ama-PCB akwa-Rogers afunwa kakhulu ezinhlelweni ezidinga ukudluliswa kwesignali yemvamisa ephezulu, ukulahlekelwa okuphansi nokuzinza. Asetshenziswa kakhulu ezimbonini ezifana nezokuxhumana, i-aerospace, medical and automotive.

I-Rogers Corporation, umhlinzeki owaziwayo wezixazululo zezinto zokwakha, yakha ama-laminates akwaRogers ikakhulukazi ukuze asetshenziswe ekwenzeni amabhodi esekethe asebenza kahle kakhulu. I-Rogers laminate iyinhlanganisela yezinto ehlanganisa indwangu ye-ceramic elukiwe ye-fiberglass enohlelo lwe-hydrocarbon thermoset resin. Le ngxube ibonisa izinto ezinhle kakhulu zikagesi njengokulahleka kwe-dielectric ephansi, ukuqhutshwa kwe-thermal okuphezulu kanye nokuzinza okuhle kakhulu kwe-dimensional.

Manje, ake sihlole inqubo yokukhiqiza ye-Rogers PCB:

1. Isakhiwo sedizayini:

Isinyathelo sokuqala sokwenza noma iyiphi i-PCB, okuhlanganisa nama-Rogers PCB, sihlanganisa ukuklama isakhiwo sesifunda. Onjiniyela basebenzisa isoftware ekhethekile ukwenza ama-schematics amabhodi esekethe, ukubeka nokuxhuma izingxenye ngendlela efanele. Lesi sigaba sokuqala sokuklama sibalulekile ekunqumeni ukusebenza, ukusebenza, nokuthembeka komkhiqizo wokugcina.

2. Ukukhetha okubalulekile:

Uma umklamo usuqediwe, ukukhetha kwempahla kuba okubalulekile. I-Rogers PCB idinga ukukhetha okubalulekile kwe-laminate, kucatshangelwa izici ezifana ne-dielectric constant edingekayo, i-dissipation factor, i-thermal conductivity, kanye nezakhiwo zemishini. Rogers laminates ayatholakala ezihlukahlukene amamaki ukuhlangabezana nezidingo ezahlukene isicelo.

3. Sika i-laminate:

Ngokuklama nokukhethwa kwezinto ezibonakalayo kuqediwe, isinyathelo esilandelayo ukusika i-laminate ye-Rogers ngosayizi. Lokhu kungafezwa kusetshenziswa amathuluzi okusika akhethekile njengemishini ye-CNC, ukuqinisekisa ubukhulu obunembile futhi kugwenywe noma yikuphi ukulimala kwezinto.

4. Ukumba nokuthela ithusi:

Kulesi sigaba, izimbobo zimbozwa ku-laminate ngokusho komklamo wesifunda. Lezi zimbobo, ezibizwa nge-vias, zihlinzeka ngoxhumano lukagesi phakathi kwezingqimba ezihlukene ze-PCB. Izimbobo ezimboziwe zibe sezifakwa ithusi ukuze kusungulwe ukuqhutshwa komsebenzi futhi kuthuthukiswe ubuqotho besakhiwo se-vias.

5. Isithombe sesifunda:

Ngemva kokumba, ungqimba lwethusi lusetshenziswa ku-laminate ukuze kwakhiwe izindlela zokuqhuba ezidingekayo ekusebenzeni kwe-PCB. Ibhodi eligqoke ithusi limbozwe ngento ezwela ukukhanya ebizwa nge-photoresist. Umklamo wesifunda ube usudluliselwa ku-photoresist kusetshenziswa amasu akhethekile afana ne-photolithography noma imaging eqondile.

6. Ukufaka:

Ngemuva kokuthi umklamo wesifunda uphrintiwe ku-photoresist, i-chemical etchant isetshenziselwa ukususa ithusi eliningi. I-etchant incibilikisa ithusi elingafunwa, ishiya ngemuva iphethini yesekethe efunekayo. Le nqubo ibalulekile ekudaleni imikhondo ye-conductive edingekayo ekuxhumekeni kukagesi kwe-PCB.

7. Ukuqondanisa ungqimba kanye ne-lamination:

Kuma-PCB e-Rogers anezingqimba eziningi, izendlalelo ngazinye ziqondaniswe ngokunembile kusetshenziswa okokusebenza okukhethekile. Lezi zingqimba zinqwabelene futhi zihlanganiswe ndawonye ukuze zakhe isakhiwo esihlangene. Ukushisa nokucindezela kusetshenziswa ekubopheni ngokomzimba nangokogesi izingqimba, ukuqinisekisa ukuqhutshwa phakathi kwazo.

8. I-Electroplating kanye nokwelashwa kwendawo:

Ukuvikela ukujikeleza kanye nokuqinisekisa ukwethembeka kwesikhathi eside, i-PCB ingena kunqubo yokucwenga kanye nokwelashwa kwendawo. Ungqimba oluncane lwensimbi (ngokuvamile igolide noma ithini) lunameka endaweni yethusi eveziwe. Lokhu kunamathela kuvimbela ukugqwala futhi inikeza indawo evumayo for soldering izingxenye.

9. Imaski ye-Solder nesicelo sesikrini sikasilika:

Indawo ye-PCB imbozwe nge-solder mask (imvamisa eluhlaza), ishiya kuphela izindawo ezidingekayo zokuxhuma izingxenye. Lesi singqimba esivikelayo sivikela iminonjana yethusi ezicini zemvelo ezinjengomswakama, uthuli, nokuthintana ngengozi. Ngaphezu kwalokho, izendlalelo zesikrini sikasilika zingangezwa ukumaka ukwakheka kwengxenye, abaklami bereferensi nolunye ulwazi olufanele endaweni ye-PCB.

10. Ukuhlola Nokulawula Ikhwalithi:

Uma inqubo yokukhiqiza isiqediwe, ukuhlolwa okuphelele kanye nohlelo lokuhlola luyenziwa ukuze kuqinisekiswe ukuthi i-PCB iyasebenza futhi ihlangabezana nezicaciso zedizayini. Ukuhlolwa okuhlukahlukene njengokuhlola ukuqhubeka, ukuhlolwa kwamandla kagesi aphezulu kanye nokuhlolwa kwe-impedance kuqinisekisa ubuqotho nokusebenza kwama-Rogers PCB.

Ngokufigqiwe

Ukwenziwa kwama-PCB akwa-Rogers kuhilela inqubo ecophelelayo ehlanganisa ukuklama nokuhleleka, ukukhethwa kwezinto ezibonakalayo, ukusika ama-laminates, ukubhoboza nokuthululwa kwethusi, ukuthwebula isithombe sesekethe, ukuqoshwa, ukuqondanisa ungqimba kanye ne-lamination, i-plating, ukulungiswa kwendawo, imaski ye-solder kanye nezicelo zokuphrinta isikrini kanye nokucophelela. ukuhlola nokulawula ikhwalithi. Ukuqonda izinto eziyinkimbinkimbi zokwenziwa kwe-Rogers PCB kugqamisa ukunakekelwa, ukunemba, kanye nobuchwepheshe obuhilelekile ekukhiqizeni lawa mabhodi asebenza kahle kakhulu.
