Moetsi oa Wave soldering Chengyuan o tla u tsebisa hore wave soldering e bile teng ka lilemo tse mashome, 'me e le mokhoa o ka sehloohong oa lisebelisoa tsa soldering, e phethile karolo ea bohlokoa kholong ea ts'ebeliso ea PCB.
Ho na le ts'ebetso e kholo ea ho etsa hore lisebelisoa tsa elektronike li fokotsehe 'me li sebetse haholoanyane,' me PCB (pelo ea lisebelisoa tsena) e etsa hore sena se khonehe.Mokhoa ona o boetse o hlahisitse lits'ebetso tse ncha tsa solder e le mokhoa o mong ho fapana le wave soldering.
Pele ho Soldering ea Wave: Nalane ea Kopano ea PCB
Ho nahanoa hore ho solder e le mokhoa oa ho kopanya likarolo tsa tšepe ho hlahile nakoana ka mor'a hore ho sibolloe thini, e ntseng e le eona ntho e ka sehloohong ho li-solders kajeno.Ka lehlakoreng le leng, PCB ea pele e hlahile lekholong la bo20 la lilemo.Motlhami wa Mojeremane e bong Albert Hansen o ne a tla ka kgopolo ya gore go nne le sefofane se se nang le dikarolo tse dintsi;e nang le li-insulating layers le li-conductors tsa foil.O boetse a hlalosa ts'ebeliso ea masoba ka har'a lisebelisoa, e leng mokhoa o ts'oanang le o sebelisoang kajeno bakeng sa ho kenya likarolo tsa likoti.
Nakong ea Ntoa ea II ea Lefatše, nts'etsopele ea lisebelisoa tsa motlakase le tsa elektroniki e ile ea qala ha lichaba li batla ho ntlafatsa puisano le ho nepahala kapa ho nepahala.Moqapi oa PCB ea sejoale-joale, Paul Eisler, o ile a qapa mokhoa oa 1936 oa ho kopanya foil ea koporo le khalase e sireletsang substrate.Hamorao o ile a bontša kamoo a ka kopanyang seea-le-moea ka mochine oa hae.Le hoja mapolanka a hae a ne a sebelisa wiring ho hokahanya likarolo, ts'ebetso e liehang, tlhahiso ea boima ba PCB e ne e sa hlokehe ka nako eo.
Leqhubu la Welding ho Pholosa
Ka 1947, transistor e ile ea qaptjoa ke William Shockley, John Bardeen, le Walter Brattain ho Bell Laboratories e Murray Hill, New Jersey.Sena se ile sa etsa hore ho be le phokotso ea boholo ba likarolo tsa elektronike, 'me tsoelo-pele e ileng ea latela ea etching le lamination e ile ea bula tsela bakeng sa mekhoa ea lihlahisoa tsa lihlahisoa.
Kaha lisebelisoa tsa elektronike li ntse li le ka masoba, ho bonolo ho fana ka solder ho boto kaofela hang-hang, ho e-na le ho li kopanya ka bomong ka tšepe ea soldering.Kahoo, wave soldering e hlahile ka ho tsamaisa boto eohle holim'a "maqhubu" a solder.
Kajeno, wave soldering e etsoa ke mochini oa wave soldering.Ts'ebetso e kenyelletsa mehato e latelang:
1. Ho qhibiliha - Solder e futhumetse hoo e ka bang 200 ° C kahoo e phalla habonolo.
2. Ho hloekisa - Hloekisa karolo ho netefatsa hore ha ho na litšitiso tse thibelang solder ho khomarela.
3. Ho beha - Beha PCB hantle ho netefatsa hore solder e fihla likarolong tsohle tsa boto.
4. Kopo - Solder e sebelisoa ho boto mme e lumelloa ho phalla libakeng tsohle.
Bokamoso ba Leqhubu la Soldering
Wave soldering e kile ea e-ba mokhoa o sebelisoang ka ho fetisisa.Sena ke hobane lebelo la eona le molemo ho feta ho solder ka letsoho, ka hona ho hlokomela boiketsetso ba kopano ea PCB.Ts'ebetso e ntle haholo ho solder ka potlako haholo, likarolo tse arohaneng hantle ka har'a lesoba.Kaha tlhoko ea li-PCB tse nyane e lebisa ts'ebelisong ea liboto tsa multilayer le lisebelisoa tsa holim'a metsi (SMDs), mekhoa e nepahetseng ea solder e hloka ho ntlafatsoa.
Sena se lebisa ho mokhoa o ikhethileng oa ho kopanya moo likhokahano li rekisoang ka bonngoe, joalo ka ha ho soasoa ka letsoho.Tsoelo-pele ea liroboto tse potlakileng le tse nepahetseng ho feta li-welding tse entsoeng ka letsoho li entse hore mokhoa ona o khonehe.
Wave soldering e ntse e le mokhoa o sebelisoang hantle ka lebaka la lebelo le ho ikamahanya le maemo ho litlhoko tse ncha tsa moralo oa PCB tse ratang tšebeliso ea SMD.Ho se ho hlahile soldering e khethehileng ea maqhubu, e sebelisang jetting, e lumellang hore ho sebelisoa ha solder ho laoloe le ho lebisoa feela libakeng tse khethiloeng.Likarolo tsa ka har'a lesoba li ntse li sebelisoa, 'me wave soldering ke mokhoa o potlakileng ka ho fetesisa oa ho kopanya likarolo tse ngata ka potlako,' me e kanna ea ba mokhoa o motle ho latela moralo oa hau.
Le hoja ts'ebeliso ea mekhoa e meng ea ho kopanya, e kang ho khetha, e ntse e eketseha butle-butle, wave soldering e ntse e na le melemo e etsang hore e be khetho e sebetsang bakeng sa kopano ea PCB.
