Sosaiti yanhasi iri kugadzira matekinoroji matsva mazuva ese, uye kufambira mberi uku kunogona kuoneka mukugadzirwa kwemabhodhi edunhu akadhindwa (PCBs).Chikamu chekugadzira chePCB chine matanho akati wandei, uye pakati peaya matanho mazhinji, solder inoita basa rakakosha pakuona kunaka kwebhodhi rakagadzirwa.Soldering inovimbisa kuti dunhu rinoramba rakagadziriswa pabhodhi, uye dai pasina kuvandudzwa kwehunyanzvi hwekutengesa, mabhodhi edunhu akadhindwa angadai asina kusimba sezvaari nhasi.Parizvino, kune akawanda marudzi ematekiniki ekutengesa anoshandiswa mumaindasitiri akasiyana.Iwo maviri anonyanya kunetseka ekutengesa matekiniki mumunda wePCB dhizaini uye kugadzira wave solder uye reflow soldering.Pane misiyano yakawanda pakati pemaitiro maviri aya ekutengesa.Hameno kuti kusiyana kupi ikoko?
Ndeupi musiyano uripo pakati pereflow soldering uye wave soldering?
Wave soldering uye reflow soldering maitiro maviri akasiyana zvachose ekutengesa.Misiyano mikuru ndeyotevera:
| wave soldering | reflow soldering |
| Mune wave soldering, zvikamu zvinotengeswa nerubatsiro rwewave crests, iyo inoumbwa neyakanyungudutswa solder. | Reflow soldering ndiyo solder yezvikamu nerubatsiro rwekuyerera, iyo inoumbwa nemhepo inopisa. |
| Kuenzaniswa nereflow soldering, wave soldering tekinoroji yakanyanya kuoma. | Reflow soldering inzira iri nyore. |
| Iyo solder process inoda kunyatsotarisisa nyaya dzakadai sekudziya kwebhodhi uye kuti yave yakareba sei mu solder.Kana iyo wave soldering nharaunda isina kuchengetedzwa zvakanaka, inogona kutungamira kune isina kukanganisa bhodhi dhizaini. | Izvo hazvidi yakananga inodzorwa nharaunda, nekudaro ichibvumira kuchinjika kukuru pakugadzira kana kugadzira akadhindwa edunhu mabhodhi. |
| Iyo wave soldering nzira inotora nguva shoma kutengesa PCB uye zvakare isingadhure kana ichienzaniswa nemamwe matekiniki. | Iyi solder nzira inononoka uye inodhura kupfuura wave soldering. |
| Iwe unofanirwa kufunga zvakasiyana zvinhu zvinosanganisira padhi chimiro, saizi, marongerwo, kupisa kupisa uye kupi kunotengeswa zvinobudirira. | Mune reflow soldering, zvinhu zvakaita seboard orientation, pad chimiro, saizi uye shading hazvifanirwe kutariswa. |
| Iyi nzira inonyanya kushandiswa munyaya yekugadzirwa kwepamusoro-soro, uye inobatsira kugadzira nhamba yakawanda yemapuranga edunhu akadhindwa munguva pfupi. | Kusiyana newave soldering, reflow soldering inokodzera diki batch kugadzirwa. |
| Kana kuburikidza-gomba zvikamu zvichizotengeswa, saka wave soldering ndiyo yakanyatsokodzera nzira yesarudzo. | Reflow soldering yakanakira solder pamusoro pekuisa zvigadziriso pamabhodhi akadhindwa edunhu. |
Ndeipi iri nani kune wave soldering uye reflow soldering?
Mhando imwe neimwe yekushongedza ine zvayakanakira nezvayakaipira, uye kusarudza nzira yakakodzera yekutengesa kunoenderana nekugadzirwa kweiyo yakadhindwa redunhu bhodhi uye zvinodiwa zvinotsanangurwa nekambani.Kana uine mibvunzo pamusoro peizvi, tapota taura nesu kuti tikurukure.
