Ke tlas'a maemo afe moo u behang lithempereichara tse fapaneng bakeng sa likarolo tse futhumatsang tsa TOP le Bottom tsa ontong ea reflow?

Maemong a mangata, li-setpoints tsa mocheso oa ontong ea reflow li tšoana bakeng sa likarolo tse futhumatsang tse kaholimo le tse tlase sebakeng se le seng.Empa ho na le maemo a khethehileng moo ho hlokahalang ho sebelisa maemo a fapaneng a mocheso ho likarolo tsa TOP le BOTTOM.Moenjiniere oa ts'ebetso ea SMT o lokela ho hlahloba litlhoko tse khethehileng tsa boto ho fumana litlhophiso tse nepahetseng.Ka kakaretso, mona ke tse ling tsa litataiso tsa ho beha mocheso oa lintho tse futhumatsang:

1. Haeba ho na le likarolo tsa lesoba (TH) holim'a boto, 'me u batla ho li khutlisetsa ka likarolo tsa SMT hammoho, u ka' na ua batla ho nahana ka ho eketsa mocheso oa karolo e ka tlaase hobane likarolo tsa TH li tla thibela ho potoloha ha moea o chesang ka lehlakoreng le ka holimo, ho thibela lipampiri tlas'a likarolo tsa TH ho tloha ho fumana mocheso o lekaneng ho etsa motsoako o motle oa ho kopanya.
2. Boholo ba lihokelo tsa TH li entsoe ka polasetiki e tla qhibiliha hang ha mocheso o phahama haholo.Moenjiniere oa ts'ebetso o tlameha ho etsa tlhahlobo pele ebe o hlahloba sephetho.
3. Haeba ho na le likarolo tse kholo tsa SMT tse kang li-inductors le aluminium capacitor ka sekepeng, u tla boela u nahane ka ho beha mocheso o fapaneng ka lebaka le tšoanang le li-connectors tsa TH.Moenjiniere o hloka ho bokella lintlha tsa mocheso oa sesebelisoa se itseng sa boto le ho lokisa boemo ba mocheso ka makhetlo a 'maloa e le hore a tsebe ho fumana mocheso o nepahetseng.
4. Haeba ho na le likarolo mahlakoreng ka bobeli a boto, hoa khoneha ho beha mocheso o fapaneng hape.

Qetellong, moenjiniere oa ts'ebetso o tlameha ho hlahloba le ho ntlafatsa boemo ba mocheso bakeng sa boto e 'ngoe le e 'ngoe.Baenjiniere ba boleng le bona ba lokela ho kenya letsoho molemong oa ho hlahloba motsoako oa solder.Mochini oa tlhahlobo ea x-ray o ka sebelisoa bakeng sa tlhahlobo e eketsehileng.
