Shamwari zhinji dzewave soldering dzine tin-yakabatana mamiriro kana uchishandisa wave soldering, zvinonetsa zvakanyanya.Zvikonzero zvikuru zvechiitiko ichi ndezvizvi zvinotevera:
Flux chiitiko haina kukwana.
Flux haina kunyorova zvakakwana.
Huwandu hwekuyerera hwakaiswa hudiki.
Uneven flux application.
Nzvimbo yebhodhi redunhu haigoni kuvharwa nekuyerera.
Hapana tin panzvimbo yedare redunhu.
Mamwe mapedhi kana solder tsoka dzakanyanya oxidized.
Circuit board wiring haina musoro (kugovera kusinganzwisisike kwezvikamu).
Nzira yekufamba nayo yakaipa.
Marata emukati haana kukwana, kana mhangura inodarika mwero;[kusvibiswa kwakanyanyisa kunokonzera kunyunguduka (mvura) yerata remvura kuti risimuke] chubhu inopupuma inovharika, uye kupupa hakuna kuenzana, zvichikonzera kupfekedzwa kusingaenzaniswi kwekuyerera pabhodhi redunhu.
Iyo mhepo banga yekumisikidza haina musoro (flux haina kuvhuvhuta zvakaenzana).
Iyo bhodhi kumhanya uye preheating haina kunyatsoenderana.
Nzira yekushanda isina kunaka kana uchinyika tini nemaoko.
Kurerekera kwecheni hakuna musoro.
Iyo crest haina kuenzana.
Sezvo kubatanidza tini kuchaita kuti pfupike redunhu pcb, inofanira kugadziriswa isati yagona kuramba kushandiswa.Iyo nzira yekugadzirisa ndeyekunongedza diki flux (kureva, rosin mafuta solvent), uye wozoshandisa yakakwira-tembiricha ferrochrome kupisa nzvimbo yetani yekubatanidza kuti inyungudutse, uye chinzvimbo chetani yekubatanidza Pasi pekuita kwekushushikana kwepasi. , ichadzokera shure uye haisisiri pfupi pfupi.
Solutions
1. Iyo inoyerera haina kukwana kana isina yunifomu yakakwana, wedzera kuyerera.
2. Lianxi inomhanyisa kumhanya uye inowedzera track angle.
3. Usashandise 1 wave, shandisa 2 mafungu ega ega, kureba kwetini hakufaniri kuva 1/2, zvakakwana kungobata pasi pebhodhi.Kana uine tireyi, divi rerata rinofanira kunge riri nechepamusoro-soro retiyi hollow.
4. Bhodhi rakaremara here?
5. Kana iyo 2-wave single shot isina kunaka, shandisa 1 wave kurova, uye 2-wave inorova pasi zvekuti inobata pini, kuitira kuti chimiro chejoint solder chigadziriswe, uye zvichave zvakanaka kana. inobuda.
Nezvikonzero zviri pamusoro, iwe unogona zvakare kutarisa kana wave solder muchina une anotevera matambudziko:
1. Peak urefu kureba.
2. Kana kumhanya kweketani kwakakodzera.
3. Tembiricha.
4. Kana huwandu hwemarata muchoto cherata hwakakwana.
5. Ko masaisai abuda mugaba here?
