PCB Soldering Izinqubo | I-HDI PCB Soldering | Ibhodi eliguquguqukayo kanye ne-Rigid-flex Board Soldering

Yethula:

Ekwenziweni kwe-electronics, i-soldering idlala indima ebalulekile ekuqinisekiseni ukwethembeka nokusebenza kwamabhodi esekethe aphrintiwe (ama-PCB). U-Capel uneminyaka engu-15 yesipiliyoni sembonini futhi ungumnikezeli oholayo wezixazululo ezithuthukisiwe ze-PCB.Kulo mhlahlandlela obanzi, sizohlola izinqubo namasu ahlukahlukene wokudambisa asetshenziswa ekwenziweni kwe-PCB, sigqamisa ubuchwepheshe be-Capel kanye nobuchwepheshe bezinqubo ezithuthukisiwe.

1. Ukuqonda i-PCB soldering: Uhlolojikelele

I-PCB soldering iyinqubo yokujoyina izingxenye ze-electronic ku-PCB usebenzisa i-solder, ingxube yensimbi encibilika emazingeni okushisa aphansi ukuze yakhe isibopho. Le nqubo ibalulekile ekwenziweni kwe-PCB njengoba iqinisekisa ukuqhutshwa kukagesi, ukuzinza kwemishini kanye nokuphathwa kwezinga lokushisa. Ngaphandle kokusoda ngendlela efanele, i-PCB ingase ingasebenzi noma isebenze kabi.

Kunezinhlobo eziningi zamasu okunamathisela asetshenziswa ekukhiqizeni i-PCB, ngayinye inezinhlelo zayo zokusebenza ngokusekelwe ezidingweni ezithile ze-PCB. Lobu buchwepheshe buhlanganisa ubuchwepheshe be-surface mount technology (SMT), ngokusebenzisa ubuchwepheshe be-hole (THT) kanye nobuchwepheshe be-hybrid. I-SMT ijwayele ukusetshenziselwa izingxenye ezincane, kuyilapho i-THT ikhethwa ezintweni ezinkulu neziqine kakhulu.

2. PCB welding ubuchwepheshe

A. Ubuchwepheshe bokushisela bendabuko

Ukushisela okukodwa futhi okukabili
I-soldering ehlangothini olulodwa kanye ne-double side amasu asetshenziswa kakhulu ekwenziweni kwe-PCB. I-soldering ehlangothini olulodwa ivumela izingxenye ukuthi zithengiswe ohlangothini olulodwa kuphela lwe-PCB, kuyilapho i-solder ezinhlangothini ezimbili ivumela izingxenye ukuthi zithengiswe nhlangothi zombili.

Inqubo ye-solder ehlangothini olulodwa ihilela ukusebenzisa i-solder paste ku-PCB, ukubeka izingxenye ezingaphezulu, bese ugeleza kabusha i-solder ukuze udale isibopho esiqinile. Lobu buchwepheshe buziboleka kumiklamo elula ye-PCB futhi bunikeza izinzuzo ezifana nokusebenza kahle kwezindleko kanye nokuhlanganisa kalula.

I-solder ezinhlangothini ezimbili,ngakolunye uhlangothi, kuhlanganisa ukusebenzisa izingxenye zembobo ezidayiselwe izinhlangothi zombili ze-PCB. Lobu buchwepheshe bukhulisa ukuzinza kwemishini futhi buvumela ukuhlanganiswa kwezingxenye eziningi.

I-Capel igxile kakhulu ekusebenziseni izindlela zokushisela ezinokwethenjelwa ezinohlangothi olulodwa nezikabili,ukuqinisekisa izinga eliphezulu nokunemba enqubweni yokushisela.

I-Multilayer PCB soldering
Ama-PCB angama-Multilayer akhiwe ngezingqimba eziningi zeminonjana yethusi nezinto zokuvalela, ezidinga amasu okunamathisela akhethekile. I-Capel inolwazi olunzulu lokuphatha amaphrojekthi we-welding we-multi-layer, eqinisekisa ukuxhumana okuthembekile phakathi kwezingqimba.

Inqubo yokuhlanganisa ye-PCB enezingqimba eziningi ibandakanya izimbobo zokubhoboza ungqimba ngalunye lwe-PCB bese umboza izimbobo ngezinto eziqhutshwayo. Lokhu kuvumela izingxenye ukuthi zithengiswe ezingqimbeni zangaphandle ngenkathi kugcinwa ukuxhumana phakathi kwezingqimba zangaphakathi.

B. Ubuchwepheshe be-welding obuthuthukisiwe

HDI PCB soldering
Ama-PCB e-High-density interconnect (HDI) aya ngokuya aduma ngenxa yekhono lawo lokufaka izingxenye eziningi kumafomu amancane. Ubuchwepheshe bokuthengisa be-HDI PCB buvumela ukuthengiswa okunembile kwezingxenye ezincane kuzakhiwo eziminyanisa kakhulu.

Ama-HDI PCB abhekana nezinselele ezihlukile ezifana nesikhala esiqinile sezingxenye, izingxenye zephimbo elihle, kanye nesidingo sobuchwepheshe be-microvia. Ubuchwepheshe benqubo obuthuthukisiwe be-Capel buvumela ukudayiswa kwe-HDI PCB okunembile, okuqinisekisa ikhwalithi ephezulu kakhulu nokwethembeka kwale miklamo eyinkimbinkimbi ye-PCB.

Ibhodi eliguquguqukayo kanye nokushisela ibhodi eliqinile
Amabhodi wesekethe aphrintiwe aguquguqukayo futhi aqinile anikeza ukuguquguquka nokuguquguquka ekwakhiweni, awenze alungele izinhlelo zokusebenza ezidinga ukugobeka noma izici zefomu elihlangene. I-soldering lezi zinhlobo zamabhodi wesifunda kudinga amakhono akhethekile ukuze kuqinisekiswe ukuqina nokuthembeka.

Ubungcweti buka-Capel ekuthengiseni ama-PCB aguquguqukayo naqinileiqinisekisa ukuthi lawa mabhodi angakwazi ukumelana nokugoba okuphindaphindiwe futhi agcine ukusebenza kwawo. Ngobuchwepheshe bezinqubo ezithuthukisiwe, i-Capel ifinyelela amalunga athembekile e-solder ngisho nasezindaweni eziguquguqukayo ezidinga ukuguquguquka.

3. Ubuchwepheshe benqubo ye-Capel ethuthukisiwe

U-Capel uzibophezele ngokuhlala ehamba phambili embonini ngokutshala imali emishinini yesimanje nezindlela ezintsha. Ubuchwepheshe benqubo yabo ethuthukisiwe bubenza bakwazi ukuhlinzeka ngezixazululo ezisezingeni eliphezulu zezidingo eziyinkimbinkimbi zokushisela.

Ngokuhlanganisa imishini yokudambisa ethuthukisiwe njengemishini yokubeka ezenzakalelayo kanye namahhavini agelezayo anezingcweti ezinekhono nonjiniyela, i-Capel ihlale iletha imiphumela yokudayiswa kwekhwalithi ephezulu. Ukuzibophezela kwabo ekunembeni nasekusunguleni izinto kubenza bahluke embonini.

Ngokufigqiwe

Lo mhlahlandlela ophelele unikeza ukuqonda okujulile kwezinqubo nezindlela zokuhlanganisa ze-PCB. Ukusuka ekuthengiseni okujwayelekile kohlangothi olulodwa nohlangothi olukabili kuya kubuchwepheshe obuthuthukile obufana ne-HDI PCB soldering ne-flexible PCB soldering, ubuchwepheshe be-Capel buyakhanya.

Ngesipiliyoni seminyaka engu-15 nokuzibophezela kubuchwepheshe bezinqubo ezithuthukisiwe, u-Capel unguzakwethu othembekile wazo zonke izidingo zokudayiswa kwe-PCB. Xhumana no-Capel namuhla ukuze uthole izixazululo ezithembekile, ezisezingeni eliphezulu ze-PCB, ezisekelwa ubuciko babo nobuchwepheshe obufakazelwe.
