Iyo reflow solder inogadzira Chengyuan yakawanikwa mukugadzirwa kwenguva refu uye kugadzira izvo zvikonzero zvikuru zve reflow solder bead ndezvinotevera:
1. Hunhu hwekutengesa zvakanyanya hunoenderana neiyo solder paste
Iyo simbi yemukati mune solder paste, dhigirii yeoxidation yehupfu hwesimbi, uye saizi yehupfu yesimbi zvese zvinogona kukanganisa chizvarwa che solder mabhora.
2. Mesh yesimbi ine simba guru
a.Stencil kuvhura
Mafekitari mazhinji anovhura stencil zvichienderana nehukuru hwepadhi, kuitira kuti zvive nyore kudhinda iyo solder paste kune solder mask layer uye kugadzira mabheji ematani, saka zviri nani kuve nekuvhurwa kweiyo stencil idiki pane saizi chaiyo. .
b.Ukobvu hwesimbi mesh
Iyo stencil Baidu inowanzova pakati pe 0.12 ~ 0.17mm, yakanyanyisa kukonzeresa "kudonha" kwesolder paste, zvichikonzera marata.
3. Kuiswa kwekumanikidzwa kwemuchina wekuisa
Kukwira ndiko kuti kana kumanikidzwa kwakanyanya, solder paste ichasvinwa kune solder resist layer, saka iyo inokwira yekumanikidza haifanire kunge yakakura.
