Ngaba ndingasebenzisa ii-PCB eziguquguqukayo ezingqongqo kwiindawo zokungcangcazela okuphezulu?

Kwiminyaka yakutshanje, ii-PCB eziguquguqukayo eziguquguqukayo ziye zafumana ukuthandwa ngenxa yoyilo lwazo olulodwa kunye nokukwazi ukujongana nemiceli mngeni ethile ebangelwe ziimeko-bume zokungcangcazela okuphezulu.Kule posi yebhlog, siza kuphonononga iingenelo zokusebenzisa ii-PCB eziguquguqukayo kwiindawo ezinjalo kwaye sixoxe ngendlela abanokuphucula ngayo ukuthembeka nokusebenza kwezixhobo zombane.

Kwihlabathi lanamhlanje, apho izixhobo zombane zisetyenziswa kuluhlu olubanzi lwezicelo, ukuqinisekisa ukuthembeka kunye nokuqina kwezi zixhobo sele kubaluleke kakhulu. Enye yezona zinto zibalulekileyo ekufuneka ziqwalaselwe kukusebenza kweebhodi zeesekethe eziprintiweyo (PCBs) kwiindawo ezishukumayo eziphezulu. Ngokukodwa kumashishini afana ne-aerospace, i-automotive kunye nezonyango, izixhobo zihlala ziphantsi kwentshukumo kunye nokungcangcazela, ngoko ke kubalulekile ukusebenzisa ii-PCB ezinokumelana neemeko ezinjalo.

1. Intshayelelo kwibhodi engqongqo-flex

I-Rigid-flex PCB yi-hybrid ye-PCB yemveli engqongqo kunye nebhodi yesekethe eguquguqukayo. Ziquka amacandelo aqinileyo kwaye aguquguqukayo adityaniswe ngokugqithwa kwimingxunya, evumela ukuyila kwe-3-dimensional (3D). Olu lwakhiwo lukhethekileyo lubonelela ngeenzuzo ezininzi, kubandakanywa ukusetyenziswa kwendawo ephuculweyo, ubunzima obuncitshisiweyo, ukuqina okuphuculweyo, kunye nokuguquguquka ngexesha lofakelo.

2. Ukuphucula ukuzinza koomatshini

Enye yeenzuzo eziphambili zeePCB eziguquguqukayo eziqinileyo kukuzinza kwazo okuphuculweyo koomatshini. Ukudityaniswa kwezinto eziqinileyo kunye neziguquguqukayo zivumela ukuba zimelane namanqanaba aphezulu okungcangcazela kunye nokutshitshiswa ngaphandle kokuchaphazela ingqibelelo yabo yesakhiwo. Oku kubaluleke ngakumbi kwiindawo zokungcangcazela okuphezulu apho ii-PCB zemveli ezingqongqo okanye iibhodi zesekethe eziguquguqukayo zinokusilela ngenxa yokusikelwa umda kwazo.

3. Nciphisa ukusilela koqhagamshelwano

Kwiindawo ezishukumayo eziphezulu, ukungaphumeleli konxibelelwano kungumba obalulekileyo kuba kunokukhokelela kwimiba yemfezeko yomqondiso okanye ukusilela kwesixhobo sonke. I-Rigid-flex PCBs isombulula le ngxaki ngokubonelela ngoqhagamshelwano oluqinileyo phakathi kweendawo eziqinileyo kunye neziguquguqukayo. Ukusetyenziswa kweplate ngemingxuma akuphuculi nje ukuthembeka komatshini, kodwa kuqinisekisa uxhulumaniso oluthembekileyo lombane kunye nokunciphisa umngcipheko wokungaphumeleli kwe-interconnect.

4. Ukuphucula ukuguquguquka koyilo

Ubunakho bokuyila be-3D yeePCB eziguquguqukayo eziguquguqukayo zibonelela ngokuguquguquka koyilo olungenakuthelekiswa nanto, okuvumela iinjineli ukuba ziphucule uyilo lwamacandelo e-elektroniki. Oku kubaluleke kakhulu kwiindawo zokungcangcazela okuphezulu njengoko kuvumela ukuba amacandelo abekwe kwiindawo ezithile, ukuphucula ukusebenza ngokubanzi kunye nokuthembeka kwezixhobo. Ukongeza, ukuphelisa izihlanganisi ezinkulu kunye neentambo zenza lula uyilo lulonke, okukhokelela ekongeni kweendleko kunye nokusetyenziswa okungcono kwendawo.

5. Ukuhlanganiswa koxinzelelo oluphezulu

Ngokuqhubekayo kwe-miniaturization yezixhobo zombane, kuye kwaba yinto engenakuphepheka ukufezekisa ukudibanisa okuphezulu. I-Rigid-flex PCBs iyagqwesa kulo mba kuba ivumela amacandelo ukuba ahlanganiswe kumacala omabini ebhodi, ngaloo ndlela kwandisa ukusetyenziswa kwendawo. Ukukwazi ukupakisha iileya ezininzi zezinto eziqinileyo kunye neziguquguqukayo kwandisa amandla okudibanisa, okwenza kube lula ukwamkela iisekethe eziyinkimbinkimbi kwiindawo zokungcangcazela okuphezulu.

6. Ukukhethwa kwezinto eziphezulu zokungcangcazela

Xa usebenzisa ii-PCB eziguquguqukayo eziqinileyo kwiindawo ezishukumayo eziphezulu, ukukhetha izinto ezifanelekileyo kubaluleka. Ukukhethwa kwezinto eziphathekayo kufuneka kuthathelwe ingqalelo izinto ezifana namandla omatshini, ukuzinza kwe-thermal kunye nokuchasana nokudinwa kwe-vibration. Umzekelo, ukusebenzisa iifilimu ze-polyimide ezinamaqondo obushushu eglasi aphezulu kunokomeleza ukuqina kwePCB kunye nokusebenza phantsi kweemeko ezinzima.

Isishwankathelo

Ukusebenzisa ii-PCB eziguquguqukayo eziqinileyo kwiindawo ezishukumayo eziphezulu zibonelela ngeenzuzo ezibalulekileyo malunga nokuzinza komatshini, ukunciphisa ukungaphumeleli kwe-interconnect, ukwandisa ukuguquguquka koyilo, kunye nokudibanisa okuphezulu. Ezi zibonelelo zibenza bafaneleke kumashishini apho izixhobo zihlala zihamba kwaye zingcangcazela. Nangona kunjalo, kubalulekile ukukhetha ngononophelo izinto ezifanelekileyo kunye neengqwalasela zoyilo ukuze kuqinisekiswe ukusebenza kakuhle kunye nokuthembeka. Ngokusebenzisa ubuchule obukhethekileyo bee-PCB eziguquguqukayo, iinjineli zinokuyila izixhobo zombane ezinokumelana nemiceli mngeni yokungcangcazela okuphezulu kunye nokuhambisa ukusebenza okuphezulu.
