Umkhiqizi we-Wave soldering u-Chengyuan uzokwethula ukuthi i-wave soldering ikhona amashumi eminyaka, futhi njengendlela eyinhloko yokuhlanganisa izingxenye, ibambe iqhaza elibalulekile ekukhuleni kokusetshenziswa kwe-PCB.
Kunomfutho omkhulu wokwenza izinto zikagesi zibe zincane futhi zisebenze kakhulu, futhi i-PCB (inhliziyo yalezi zisetshenziswa) yenza lokhu kwenzeke.Lo mkhuba uphinde waveza izinqubo ezintsha zokuhlanganisa njengenye indlela yokuhlanganisa amaza.
Ngaphambi kwe-Wave Soldering: Umlando Womhlangano we-PCB
Ukudayiswa njengenqubo yokuhlanganisa izingxenye zensimbi kucatshangwa ukuthi kwavela ngemva nje kokutholwa kwethini, okuseyisici esivelele kuma-solder namuhla.Ngakolunye uhlangothi, i-PCB yokuqala yavela ekhulwini lama-20.Umsunguli waseJalimane u-Albert Hansen waqhamuka nombono wendiza enezigaba eziningi;ehlanganisa izingqimba ezivikelayo kanye nama-conductor we-foil.Ubuye wachaza nokusetshenziswa kwezimbobo emishinini, okuyindlela efanayo esetshenziswa namuhla ekufakweni kwengxenye yembobo.
Phakathi neMpi Yezwe II, ukuthuthukiswa kwezinto zikagesi neze-elekthronikhi kwaqala njengoba amazwe ayefuna ukuthuthukisa ezokuxhumana nokunemba noma ukunemba.Umsunguli we-PCB yesimanje, u-Paul Eisler, wasungula inqubo ngo-1936 yokuhlanganisa ucwecwe lwethusi endaweni engaphansi yengilazi yokuvikela.Kamuva wabonisa indlela yokuhlanganisa umsakazo ocingweni lwakhe.Nakuba amabhodi akhe asebenzisa izintambo ukuxhuma izingxenye, inqubo ehamba kancane, ukukhiqizwa kwe-PCB ngobuningi kwakungadingeki ngaleso sikhathi.
Wave Welding to Rescue
Ngo-1947, i-transistor yasungulwa nguWilliam Shockley, uJohn Bardeen, noWalter Brattain eBell Laboratories eMurray Hill, eNew Jersey.Lokhu kuholele ekuncipheni kobukhulu bezingxenye ze-elekthronikhi, futhi intuthuko eyalandela yokunamathisela kanye ne-lamination yavula indlela yamasu okudambisa izinga lokukhiqiza.
Njengoba izakhi ze-elekthronikhi zisezimbotsheni, kulula kakhulu ukuhlinzeka nge-solder kulo lonke ibhodi ngesikhathi esisodwa, kunokuba uzithengise ngazodwana nge-soldering iron.Ngakho-ke, i-wave soldering yazalwa ngokugijima ibhodi lonke phezu "kwamagagasi" e-solder.
Namuhla, i-wave soldering yenziwa ngomshini we-wave soldering.Inqubo ihlanganisa lezi zinyathelo ezilandelayo:
1. Ukuncibilika - I-solder ishisisa cishe ku-200 ° C ngakho igeleza kalula.
2. Ukuhlanza - Hlanza ingxenye ukuze uqiniseke ukuthi azikho izithiyo ezivimbela i-solder ekunamatheleni.
3. Ukubekwa - Beka i-PCB kahle ukuze uqinisekise ukuthi i-solder ifinyelela kuzo zonke izingxenye zebhodi.
4. Isicelo - I-Solder isetshenziswa ebhodini futhi ivunyelwe ukugeleza kuzo zonke izindawo.
Ikusasa Le-Wave Soldering
I-Wave soldering yake yaba yindlela evame ukusetshenziswa kakhulu yokuhlanganisa.Lokhu kungenxa yokuthi ijubane layo lingcono kune-soldering manual, ngaleyo ndlela ibona ukuzenzekelayo komhlangano we-PCB.Le nqubo inhle kakhulu ekuhlanganiseni izinto ngokushesha okukhulu, ezihlukaniswe kahle ngembobo.Njengoba isidingo sama-PCB amancane siholela ekusetshenzisweni kwamabhodi anezingqimba eziningi kanye namadivayisi okufakwa endaweni ephezulu (ama-SMD), amasu okunamathisela anembe kakhudlwana adinga ukuthuthukiswa.
Lokhu kuholela endleleni ekhethiwe yokuhlanganisa lapho okuxhunywayo kudayiswa khona ngakunye, njengasekuhlanganisweni kwesandla.Intuthuko kumarobhothi ashesha futhi anembe ngaphezu kokushisela ngesandla kwenze kwaba nokwenzeka ukuzenzela kwendlela.
I-Wave soldering isalokhu iyindlela esetshenziswe kahle ngenxa yejubane layo nokuvumelana nezimo ezintsha zezidingo ze-PCB design ezivuna ukusetshenziswa kwe-SMD.I-selective wave soldering ivele, esebenzisa i-jetting, evumela ukusetshenziswa kwe-solder ukuthi ilawulwe futhi iqondiswe kuphela ezindaweni ezikhethiwe.Izingxenye zembobo zisasetshenziswa, futhi i-wave soldering iyindlela eshesha kakhulu yokuhlanganisa ngokushesha izinombolo ezinkulu zezingxenye, futhi kungase kube indlela engcono kakhulu, kuye ngomklamo wakho.
Nakuba ukusetshenziswa kwezinye izindlela zokunamathisela, njengokukhetha okukhethiwe, kukhula kancane kancane, i-wave soldering isenazo izinzuzo ezikwenza kube inketho esebenzayo yokuhlanganisa i-PCB.
