Nhoroondo ye wave soldering

Wave soldering mugadziri Chengyuan achakuzivisa kwauri kuti wave soldering yavepo kwemakumi emakore, uye senzira huru yekugadzira zvinhu, yakaita basa rakakosha mukukura kwePCB kushandiswa.

Pane kusundidzira kukuru kuita kuti zvemagetsi zvidiki uye zvishande, uye PCB (moyo wemidziyo iyi) inoita kuti izvi zvigoneke.Aya maitiro akaburitsawo maitiro matsva ekutengesa seimwe nzira yekuve wave soldering.

Pamberi peWave Soldering: PCB Gungano Nhoroondo

Soldering senzira yekubatanidza nhengo dzesimbi inofungidzirwa kuti yakatanga nguva pfupi mushure mekuwanikwa kwetin, iyo ichiri chinhu chikuru mumasoja nhasi.Kune rumwe rutivi, PCB yokutanga yakaonekwa muzana remakore rechi20.Muumbi weGermany Albert Hansen akauya nepfungwa yendege ine multilayer;inosanganisira insulating layers uye foil conductors.Akatsanangurawo mashandisirwo emakomba mumidziyo, inova ndiyo nzira imwe chete inoshandiswa nhasi pakuisa-paburi rechikamu.

Munguva yeHondo Yenyika II, kugadzirwa kwemidziyo yemagetsi neyemagetsi kwakatanga sezvo nyika dzaitsvaga kuvandudza kufambiswa kwemashoko uye huchokwadi kana huchokwadi.Muvambi wePCB yemazuva ano, Paul Eisler, akagadzira nzira muna 1936 yekubatanidza foil yemhangura kune girazi rinodzivirira substrate.Akazoratidza nzira yekubatanidza radio pamudziyo wake.Kunyange zvazvo mapuranga ake akashandisa wiring kubatanidza zvikamu, zvishoma nezvishoma, kugadzirwa kwePCBs kwaisadiwa panguva iyoyo.

Wave Welding kune Rescue

Muna 1947, transistor yakagadzirwa naWilliam Shockley, John Bardeen, naWalter Brattain kuBell Laboratories muMurray Hill, New Jersey.Izvi zvakakonzera kudzikiswa kwehukuru hwezvinhu zvemagetsi, uye kuvandudzwa kwakatevera mukushongedza uye lamination kwakagadzira nzira yekugadzira-giredhi solder tekinoroji.
Sezvo zvigadzirwa zvemagetsi zvichiri kuburikidza nemakomba, zviri nyore kupa solder kubhodhi rose panguva imwe chete, pane kuzvitengesa mumwe nomumwe nesimbi inotengeswa.Saka, wave soldering yakazvarwa nekumhanyisa bhodhi rose pamusoro pe "mafungu" e solder.

Nhasi, wave soldering inoitwa newave soldering muchina.Iyo nzira inosanganisira matanho anotevera:

1. Kunyunguduka - Solder inopisa kusvika ku200 ° C saka inoyerera nyore nyore.

2. Kuchenesa - Chenesa chikamu kuti uone kuti hapana zvipingamupinyi zvinodzivisa solder kunamatira.

3. Kuiswa - Isa PCB zvakanaka kuti uone kuti solder inosvika kumativi ose ebhodhi.

4. Kushandisa - Solder inoshandiswa kubhodhi uye inobvumirwa kuyerera kunzvimbo dzose.

Ramangwana reWave Soldering

Wave soldering yaimbove yainyanya kushandiswa solder tekinoroji.Izvi zvinodaro nekuti kumhanya kwayo kurinani pane manyore solder, nekudaro kuona otomatiki yePCB gungano.Maitiro acho akanyanya kunaka pakusodha nekukurumidza, yakanyatso kupatsanurwa kuburikidza ne-gomba zvikamu.Sezvo kudiwa kwemaPCB madiki kuchitungamira mukushandiswa kweakawanda mabhodhi uye epamusoro Mount midziyo (SMDs), mamwe chaiwo ekutengesa matekiniki anofanirwa kugadzirwa.

Izvi zvinotungamira kune yakasarudzika solder nzira iyo iyo majoini anotengeswa ega, sekunge mukugadzira ruoko.Kufambira mberi mumarobhoti ari kukurumidza uye akanyatsojeka kupfuura manual welding akaita kuti zvikwanisike otomatiki yenzira.

Wave soldering inoramba iri nzira yakanyatso shandiswa nekuda kwekumhanya kwayo uye kuchinjika kune nyowani PCB dhizaini zvinodiwa izvo zvinofarira kushandiswa kweSMD.Selective wave soldering yakabuda, iyo inoshandisa jetting, iyo inobvumira kushandiswa kwe solder kudzorwa uye kutungamirirwa chete kunzvimbo dzakasarudzwa.Kuburikidza ne-gomba zvikamu zvichiri kushandiswa, uye wave soldering ndiyo nzira inokurumidza kukurumidza kushambadzira huwandu hukuru hwezvikamu, uye inogona kunge iri nzira yakanakisa, zvichienderana nemagadzirirwo ako.

Kunyangwe kushandiswa kwedzimwe nzira dzekutengesa, dzakadai sekusarudza solder, kuri kuwedzera zvishoma nezvishoma, wave soldering ichine zvakanakira zvinoita kuti ive sarudzo inoshanda yePCB kusangana.
