Muchirongwa chekugadzirwa kweSMT, zvinowanzodikanwa kushandisa SMD adhesive, solder paste, stencil uye zvimwe zvinhu zvekubatsira, izvi zvekubatsira zvinhu muSMT rese rekugadzira gungano rekugadzira, kunaka kwechigadzirwa, kugona kwekugadzira kunoita basa rakakosha.
1. Nguva yekuchengeta (Sherufu Hupenyu)
Pasi pemamiriro akatsanangurwa, zvinhu kana chigadzirwa chinogona kuramba chichisangana nezvinodiwa zvehunyanzvi uye kuchengetedza kushanda kwakakodzera kwenguva yekuchengetedza.
2. Nguva yekuisa (Nguva yekushanda)
Chip adhesive, solder paste iri kushandiswa isati yaonekwa kune yakatsanangurwa nharaunda inogona kuramba ichichengetedza yakatsanangurwa kemikari uye yemuviri zvimiro zvenguva refu kwazvo.
3. Viscosity (Viscosity)
Chip adhesive, solder paste mune yakasikwa drip yeadhesive zvimiro zvekudonha kunonoka.
4 Thixotropy (Thixotropy Ratio)
Chip adhesive uye solder paste ine hunhu hwemvura kana yakawedzera pasi pekumanikidzwa, uye nekukasira kuita purasitiki yakasimba mushure meextrusion kana kumisa kumanikidza.Hunhu uhu hunonzi thixotropy.
5. Kudonha (kudonha)
Mushure mekudhindwa kwestencil printernekuda kwegiravhiti uye kushushikana kwepamusoro uye kukwira kwekushisa kana nguva yekupaka yakareba uye zvimwe zvikonzero zvinokonzerwa nekuderedzwa kwehurefu, nzvimbo yepasi kupfuura muganhu wakatarwa wechiitiko chekudonha.
6. Kupararira
Iyo chinhambwe icho chinonamira chinopararira pakamuri tembiricha mushure mekuparadzira.
7. Kunamatira (Tack)
Ukuru hwekunamatira kwe solder paste kune zvikamu uye kuchinja kwekunamatira kwayo nekuchinja kwekuchengetedza nguva mushure mekudhinda kwe solder paste.
8. Kunyorova (Wetting)
Iyo yakanyungudutswa solder munzvimbo yemhangura kuti iite yunifomu, yakatsetseka uye isina kuputika mamiriro eiyo solder yakaonda layer.
9. No-clean Solder Paste (No-clean Solder Paste)
Solder paste inongori chidimbu chezvisingakuvadzi zvakasara mushure mekutengesa pasina kuchenesa PCB.
10. Low Temperature Solder Paste (Low Temperature Paste)
Solder paste ine tembiricha yekunyunguduka yakaderera pane 163 ℃.
