Nekuvandudzwa kwe miniaturization uye kunyatsojeka kwezvigadzirwa zvemagetsi, iyoPCB gungano kugadzirauye density yegungano inoshandiswa nemagetsi ekugadzira michina iri kuramba ichikwira uye ichikwira, majoini ekutengesa mumabhodhi ematunhu ari kuita madiki uye madiki, uye michina, yemagetsi uye thermodynamic mitoro yavanotakura iri kuramba ichikwira nekukwira.Zviri kuwedzera kurema uye zvinodiwa kuti kugadzikana zviri kuwedzerawo.Zvisinei, dambudziko rePCB gungano solder joint kukundikana richasanganawo mune chaiyo yekugadzirisa maitiro.Izvo zvinodiwa kuti uongorore uye uwane chikonzero chekudzivisa iyo solder joint kutadza kuitika zvakare.
Saka nhasi, isu tichakuzivisai zvikonzero zvikuru zvekutadza kwePCB gungano kugadzirisa masodha majoini.
Zvikonzero zvikuru zvekutadza kwePCB musangano kugadzirisa solder majoini:
1. Murombo chikamu mapini: plating, kusvibiswa, oxidation, coplanarity.
2. Yakashata PCB pads: plating, kusvibiswa, oxidation, warpage.
3.Solder quality defects: kuumbwa, kusvibiswa kusina kukwana, oxidation.
4. Flux quality defects: low flux, high corrosion, low SIR.
5. Process parameter control defects: kugadzira, kutonga, midziyo.
6. Zvimwe zvinhu zvekubatsira zvinokanganisa: zvinonamatira, mumiririri wekuchenesa.
Nzira dzekuwedzera kugadzikana kwePCB musangano solder majoini:
Kuedza kwekugadzikana kwePCB musangano solder joints kunosanganisira kugadzikana kuedza uye kuongorora.
Kune rumwe rutivi, chinangwa chayo ndechekuongorora uye kuona kugadzikana kwehutano hwePCB musangano wakabatanidzwa wedunhu zvishandiso, uye nekupa zvigadziro zvekugadzikana kwekugadzirwa kwemuchina wose.
Ukuwo, mukuita kwePCB musanganokugadzirisa, zvakakosha kuvandudza kugadzikana kwemajoini ekutengesa.Izvi zvinoda kuongororwa kwechigadzirwa chakakundikana, kutsvaga nzira yekutadza, uye kuongorora chikonzero chekutadza.Chinangwa ndechekudzokorora nekuvandudza maitiro ekugadzira, zvimiro zvemaparamita, welding process, uye kugadzirisa goho rePCB musangano kugadzirisa.Iyo yekutadza maitiro ePCB gungano solder majoini ndiyo hwaro hwekufanotaura hupenyu hwayo kutenderera uye nekumisikidza yayo yemasvomhu modhi.
Mune izwi, Tinofanira kuvandudza kugadzikana kwemajoini ekutengesa uye kuvandudza goho rezvigadzirwa.
