PCBA oa potoloho boto tjheseletsa diseke ee bothata ba batho ba batsho ke ho feta atileng oa potoloho boto bobe ketsahalo, ho fella ka PCBA tjheseletsa diseke ee ba batsho ka mabaka a mangata, empa hangata e bakoa ke mabaka a latelang:
1, pad oxidation: Haeba pad ea PCBA e pepesehetse mongobo ka nako e telele, e tla etsa hore bokaholimo ba pad bo oxidize, bo etse filimi ea oxide holim'a pad, e bakang botsho, ka hona, ha u boloka PCBA, tlhokomelo e lokela ho lefshoa ho boloka tikoloho e omme, 'me ka nako e ts'oanang, PCBA e lokela ho tlosoa ka nako ho qoba ho pepeseha ha eona nako e telele moeeng!
2, mathata a ts'ebetso ea welding: ho reflow welding kapa wave soldering, haeba mocheso oa welding o phahame haholo kapa nako ea welding e le telele haholo, e tla lebisa ho oxidation ea "welding pad black phenomenon", karabelo ena hangata e bakoa ke ho chesoa. mocheso feta kgothaletswa mocheso mefuta e fapaneng ya solder, ho fella ka ho potlakisa oxidation tshebetso, kahoo ka tshebetso tjheseletsa e lokela ho ba ho ya ka dipehelo tsa tshebetso bakeng sa tjheseletsa!
3, solder bothata: solder ka kakaretso e bua ka solder peista, thini, solder boleng e ntle kapa e mpe, haeba tshebediso ya boleng bo tlaase solder, tla boela etsa hore solder ka lintho tse kotsi le litšila lokolloa, ho fellang ka letlapa le batsho, kahoo, khethong ea solder, re tlameha ho qoba ho sebelisa solder ea boleng bo tlaase!
4, mathata a ho hloekisa: Ka kakaretso, tabeng ea tšebeliso ea flux e hlokahalang ho hloekisa boto, e le ho tlosa masala a phallo holim'a pad, 'me haeba masala a phallang a sa tlosoe ka ho feletseng, joale mefuta ena e setseng e ka senyeha. kapa carbonize ka mocheso o phahameng, e le hore pad e hlahe e ntšo. Ka hona, ho hloekisa ka nako e nepahetseng ka mor'a ho cheselletsa ho hlokahala haholo!
5, mathata a likarolo: haeba boleng ba likarolo tsa elektronike bo se botle, kapa thepa ea pini ea karolo e fosahetse, e ka boela ea lebisa ketsahalong ea "black welding disc", kahoo, ha re khetha likarolo tsa elektronike, re tlameha ho khetha boleng bo botle. likarolo ho etsa bonnete ba hore boleng ba ho roala le lisebelisoa tsa pin tsa likarolo li tšoaneleha.
Ka holimo ke lebaka le ka sehloohong bakeng sa PCBA tjheseletsa terei e ntšo, 'me ho ea ka mabaka a fapaneng, re ka boela khetha mehato e tsamaisanang ntlafatso, e le hore ka katleho fokotsa bothata ba PCBA tjheseletsa terei e ntšo, ho ntlafatsa boleng ba lihlahisoa!
