SMT ninyungu zayo mubibaho byumuzunguruko

SMT ni iki? Kuki SMT yemerwa muri rusange, kumenyekana no kuzamurwa ninganda za elegitoronike imaze gusohoka? Uyu munsi Capel azayifungura kubwawe umwe umwe.

Ikoranabuhanga rya Surface:

Nugushiraho mbere-gushiraho ifu isa nifu ya poro (kugurisha ibicuruzwa bigufi) kuri padi zose kugirango zihurizwe kuri PCB mugucapisha, gutwikira ahantu, cyangwa gutera, hanyuma ibice byubuso (SMC / SMD)) kuri umwanya ugaragara hejuru yubuso bwa PCB, hanyuma urangize gusana no guhuza paste yuwagurishije kumurongo wose wagurishijwe ugurisha mumatanura yihariye kugirango urangize inzira yose yo guhuza PCBA. Ikusanyirizo ryikoranabuhanga ryitwa tekinoroji yubuso, izina ryicyongereza ni “Surface Mount Technology, SMT muri make.

Kuberako ibicuruzwa bya elegitoronike byakusanyirijwe hamwe na SMT bifite urukurikirane rwibyiza byuzuye nkubunini buto, ubuziranenge bwiza, ubwizerwe buhanitse, uburyo bwo gukora bwikora, umusaruro mwinshi, ibicuruzwa bihoraho, nibikorwa byiza bihenze, byamenyekanye cyane kandi bitoneshwa na electronics inganda. None, nyuma yuko ibicuruzwa byemeje SMT, ni izihe nyungu ibicuruzwa bishobora kunguka?

Ibyiza byo gukoresha SMT kubicuruzwa:

1. Ubwinshi bw'iteraniro ryinshi: Muri rusange, ugereranije na THT inzira, gukoresha SMT birashobora kugabanya ingano y'ibicuruzwa bya elegitoronike 60% kandi bikagabanya ibiro 75%;

2. Kwizerwa kwinshi: Byombi igipimo cyambere cyo guhuza ibicuruzwa byagurishijwe mugukora ibicuruzwa nigihe cyo hagati yo kunanirwa (MTBF) byibicuruzwa byatejwe imbere cyane;

3. Ibyiza biranga imirongo myinshi: Kubera ko SMC / SMD mubusanzwe idafite icyerekezo cyangwa inzira ngufi, ingaruka za parasitike inductance na capacitance ziragabanuka, ibintu byinshi biranga umuzunguruko biratera imbere, kandi igihe cyo kohereza ibimenyetso kigufi;

4. Igiciro gito: Agace ka PCB gakoreshwa kuri SMT ni 1/12 gusa cyubuso bwa THT hamwe numurimo umwe. SMT ikoresha PCB kugirango igabanye gucukura cyane, igabanya ibiciro byo gukora PCB; kugabanya ingano nubuziranenge bizigama cyane ikiguzi cyo gupakira ibicuruzwa no gutwara; igiciro rusange cyibicuruzwa cyaragabanutse cyane, kandi irushanwa ryuzuye ryibicuruzwa ku isoko ryongerewe. imbaraga;

5. Korohereza umusaruro wikora: Mubikorwa rusange, birashobora kuba byikora byuzuye, hamwe nibisohoka byinshi, ubushobozi bunini, ubuziranenge buhamye, kwizerwa cyane, hamwe nigiciro gito cyibicuruzwa.

Shenzhen Capel Technology Co., Ltd. yashinze uruganda rukora ibicuruzwa byumuzunguruko kuva 2009 kandi rutanga serivisi zo guteranya SMT PCB. Mu myaka 15 ishize, yakusanyije uburambe bukomeye, itsinda ryumwuga, imashini nibikoresho bigezweho, hamwe nubushobozi buhanitse bwo gukora. Yakemuye ibibazo bitandukanye kubibazo byumushinga wabakiriya.
