Manje kunamaselula namakhompyutha aphathekayo amaningi ukwedlula bonke abantu emhlabeni. Ngemva kokusebenzisa kahle le mishini ephathwayo, abacwaningi bawabhanqa ngempumelelo emzimbeni wokugcina ongagaywa kabusha, okuholele emishinini evumelana nemvelo embonini yokukhiqiza izinto zikagesi. Ngokufanayo, ngokufika kwe-PCBS encibilikayo, umphakathi wezokwelapha nawo wenze okusha ngokushesha. Ucwaningo lwezokwelapha luqale lwahlongoza umqondo wezinto zikagesi ezihlakazekayo: uma sezihlakaziwe, ziyanyamalala. Ngaphezu kwalokho, umqondo we-PCBA oncibilikayo onekhono uhola isidingo sezokwelapha sobuchwepheshe obuhlukile obufana neziqaphi zobuchopho, izikhuthazi zikagesi ezisheshisa ukuthuthukiswa kwamathambo, nezinhlelo zokulethwa kwezidakamizwa eziwafaka emzimbeni.
Kusukela kumaphampu e-insulin kuya kuma-pacemakers, izifakelo zikagesi zingamathuluzi omshwalense wezempilo anamandla, anezinsizakusebenza ezinhle. Kodwa-ke, banohlu lwezingozi eziphakeme mayelana nezinkinga zokuhlinzwa kanye nempilo. Ubuchwepheshe be-Soluble PCBA buvela nalezi zidingo ezibalulekile embonini yezokunakekelwa kwempilo. Ngokuthuthuka okusha kwemboni yokukhiqiza ama-elekthronikhi, ingcebo yayo yanda kancane kancane yafinyelela ku-electronics abathengi, ubuchwepheshe bokubuyisela kabusha, imboni yasolwandle kanye neminye imikhakha ebalulekile.
Ubuchwepheshe obusha be-PCBA busekela ukusungulwa kwezokwelapha, futhi ngaphezu kokusekela ukunakekelwa kwezempilo okuqinile nokuthuthukisiwe emkhakheni wemitholampilo nezibhedlela, kungase futhi kusebenze ezindaweni ezihlukahlukene zezinhlungu ezinekhono eliphezulu lokuqapha isiguli. I-Soluble PCB prototypes yenze izinto eziningi ezintsha ezitholakele emkhakheni wezogesi zezokwelapha, zonga isikhathi ngokugwema ukuhlinzwa okwengeziwe, ukunciphisa inkimbinkimbi yezokwelapha, nokuhlinzeka iziguli ukwelashwa okuthembekile nokungebuhlungu kangako. Njengendawo entsha embonini yezokwelapha, ezempilo kanye nezimboni zamazinyo, imvamisa ephezulu yamanje kanye nezitayela zemisebenzi eminingi ziyathuthuka, okubonisa ukwanda okuphawulekayo kokuqanjwa kabusha kwe-elekthronikhi kumabhodi wesifunda aphrintiwe.
PCB encibilikayo ngaphakathi
I-flux encibilikayo emanzini ingenye yezingxube ezihlukahlukene ekuhlanganiseni kwe-PCB okushiya inqubo yokunamathisela i-solder phezulu emoyeni futhi isebenza njengendawo yokuqeda izinhlayiya ze-solder. Yakhiwe ngama-asidi e-organic ebolayo futhi asebenzayo. Ezingxenyeni ezijwayelekile ze-PCB ezincibilikayo, kubalulekile ukushiya bese usetha izinga elibalulekile lensalela ye-corrosion flux ebhodini lesekethe eliphrintiwe. Ngokusekelwe ku-geometry yebhodi, ukwakheka kwezinto, kanye nohlobo nevolumu yokuguquguquka, ukukhishwa kwe-flux sekuphenduke indawo eshisayo yokwenziwa ngempumelelo kwe-PCBS encibilikayo. Lokhu kungenxa yokuthi uma noma yikuphi ukugeleza kusala ebhodini, kungase kwandise amathuba okuthi i-ECM ibangele ukwehluleka okukhulu. Ngemuva kokuthi inqubo ye-reflow soldering isiqediwe nge-flux kanye nokunamathisela okuncibilika emanzini ku-PCB, insalela ye-flux iyasuswa.
I-PCB encibilikayo
Manje, i-PCBA encibilikayo ingahlangabezana nezidingo eziqondile zohlaka oluyinkimbinkimbi kanye nokuqapha kwengqondo okubalulekile. Lawa ma-chips amancane, angafakwa ebuchosheni, angasiza odokotela baqaphe abantu abahlinzwa ubuchopho noma abahlukumezekile ekhanda. Izingxenye ze-PCB ezincibilikayo nazo ziyigxathu eliya phambili ekulungisweni kwemishini ye-neurodiagnostic, enenqubekela phambili ekuchazeni umzimba nengqondo ehlobene nezifo ze-neurodeergenerative, izifo ezingamahlalakhona kanye nekhwalithi yokulala yeziguli.
Inqubekelaphambili eqhubekayo kanye nokuqanjwa okusha kwesayensi kungasiza abantu abaningi. Njengabantu bemboni ye-PCB, umzimba ngokwemvelo nawo uthwala umthwalo wokusungula izinto ezintsha, ngithemba ukuthi mina nawe sizoqhubeka nokusebenza kanzima ukuze siye phambili.
