I roto i te tirotiro SMT, he maha nga wa e whakamahia ana te tirotiro tirohanga me te tirotiro taputapu.Ko etahi tikanga he tirohanga tirohanga anake, ko etahi he tikanga whakauru.Ka taea e raua tokorua te tirotiro i te 100% o te hua, engari ki te whakamahia te tikanga tirohanga tirohanga, ka ngenge tonu nga tangata, na reira kaore e taea te whakarite kia 100% te tirotiro tupato nga kaimahi.Na reira, ka whakatauhia e matou he rautaki taurite mo te tirotiro me te aro turuki ma te whakarite i nga waahanga whakahaere kounga.
Hei whakarite i te mahi noa o nga taputapu SMT, whakakaha te tirotiro i te kounga o te taputapu mahi miihini i ia mahi, kia aro turukihia tona ahua rere, me te whakarite i nga tohu whakahaere kounga i muri i etahi mahinga matua.
Ko enei waahi whakahaere kei te nuinga o nga waahi kei nga waahi e whai ake nei:
1. Te tirotiro PCB
(1) Karekau he rerekeetanga o te papa kua taia;
(2) Ahakoa te oxidized te papa fehokotaki'anga;
(3) Karekau he rakuraku i te mata o te papa kua taia;
Tikanga tirotiro: Te tirotiro tirohanga kia rite ki te paerewa tirotiro.
2. Te kitenga mata mata
(1) Mehemea kua oti te tuhi;
(2) Mehemea he piriti;
(3) Ahakoa he rite te matotoru;
(4) Karekau he mata tiango;
(5) Karekau he rereke i roto i te whakaputanga;
Tikanga tirotiro: te tirohanga tirohanga, te tirotiro karaihe whakanui ranei i runga i te paerewa tirotiro.
3. Whakamatau papaki
(1) Ko te waahi whakauru o nga waahanga;
(2) Ahakoa he maturuturu;
(3) Kaore he waahanga he;
Tikanga tirotiro: te tirohanga tirohanga, te tirotiro karaihe whakanui ranei i runga i te paerewa tirotiro.
4. Rerenga umurapunga
(1) Ko te ahuatanga o te whakapiringa o nga waahanga, ahakoa he piriti, he poupou, he dislocation, he poi hikoi, he hononga mariko me etahi atu ahuatanga o te hononga kino.
(2) Te ahuatanga o te hononga solder.
Tikanga tirotiro: te tirohanga tirohanga, te tirotiro karaihe whakanui ranei i runga i te paerewa tirotiro.
