uhlamvu lwemali pusher uhlu lokuhlola izinga: uma uthenga imishini yokuphusha uhlamvu lwemali e-China, ungaqageli-ukuhlola. Lo mhlahlandlela osebenzayo wefekthri{2}}wokucwaninga ubeka izinyathelo eziyisikhombisa ezibalulekile zamathimba okuthenga: ubuqotho bokupakisha, ukuhlolwa kwe-PCB, ukuhlola impilo yemoto, ukuhlola indlela ye-hopper kanye{3}}nohlamvu lwemali, izilawuli ze-firmware, imibhalo kanye nezingxenye ezisele, kanye{4}}nokushiswa{4}}ekuqinisekisweni. Ekugcineni ungadawuniloda isipredishithi esilungele-ukusisebenzisa{7}}ukuhlola ukuze siqalise phakathi nokuhlolwa kwesampula.
Kungani kufanele kwenziwe ukuhlolwa kwefekthri? (Yini inhloso?)
Ukuhlolwa kwefekthri nokuhlolwa kwesampula kuvimbela ukubuyisela eqolo, ubuhlungu bekhanda lewaranti, kanye nezikhalazo zamakhasimende. Ukuze uthole uhlamvu lwemali oluphusha amaphutha, amaphutha amancane (injini ebuthakathaka, ukusoda kwe-PCB edodayo, noma ukuvikeleka kabi kwekhreyithi) kuhumushela emidlalweni elahlekile nesikhathi sokuphumula phansi. Sebenzisa lokhui-factory audit coin pusheruhlu lokuhlola ukuze kuvikelwe umkhawulo nesithunzi.
1. Ukupakishwa nokuhlola ikhreyithi - okufanele uhlole (Ukwenza kanjani)
Qinisekisa amandla ekhreyithi angaphandle, izivikeli zamakhona, umgoqo womswakamo, kanye nezimpawu zokuthumela ezifanele.
Vula ikhreyithi yesampula: hlola i-cushioning yangaphakathi (igwebu/i-ply), izihlukanisi, nokunganyakazi. Ukupakisha okungalungile kuholela emonakalweni wezokuthutha{1}}idokhumenti enezithombe.
2. I-PCB nokuhlolwa nge-elekthronikhi - amasiginali okhiye okufanele abukwe
Hlola amajoyinti e-solder, ukubekwa kwengxenye, kanye ne-conformal coating. Amalunga abandayo e-solder, izinsalela ze-flux, noma izingxenye ezingekho amafulegi abomvu.
Qinisekisa izingxenye zemikhiqizo zezingxenye ezibalulekile (izilawuli zamandla kagesi, ama-MOSFET) futhi ucele umbiko wokuhlola obonakalayo we-IPC.
3. Ukuhlola impilo yezimoto negiya - ukuthi kungani kubalulekile
Qalisa imijikelezo yempilo yezimoto kumayunithi esampula (enconyiwe imijikelezo engu-1,000–10,000 kuye ngokucaciswa) futhi ulinganise ukutonyulwa kwamanje. Amandla amaningi noma umsindo ubikezela ukwehluleka kwangaphambi kwesikhathi.
Cela idatha yomkhiqizi we-MTBF namasampula ologi okuhlola. Ukwehluleka "kwempilo yemoto" kuyimbangela ehamba phambili yokungasebenzi kwenkundla.
4. I-Hopper, indlela yemali kanye namasheke okuqinisekisa
Hlola ukugeleza kohlamvu lwemali ngamahlelo okuhlosiwe namathokheni; qinisekisa ukuthi izinzwa zibhalisa ngokunembile futhi izindlela ze-hopper azihlanganisi.
Qinisekisa abamukeli bezikweletu noma iziqinisekisi uma zifakiwe; hlola ukulinganisa kanye namazinga okunqatshwa kokukhwabanisa.
5. I-Firmware, isilawuli senguqulo nokumisa
Qinisekisa ukuthi inguqulo ye-firmware ifana ne-spec futhi ifakwe ilebula. Cela inqubo yezibuyekezo ze-firmware ephephile futhi ubuze ukuthi izingidi ze-bootloader ziyasetshenziswa yini.
Qinisekisa izilungiselelo zamaphesenti enkokhelo kanye nokukhishwa kwethikithi kufinyeleleka kuphela ngemodi yesevisi eqinisekisiwe.
6. Amadokhumenti,{1}}izingxenye ezisele kanye nokulebula
Idinga-uhlu lwezingxenye ezisele (amarabha, amamotho, amafuse, ama-bulb) kanye nokulebula kwezixhumi ze-PCB. Ikhithi eyisipele efakiwe{2}}yehlisa i-MTTR.
Thola imanyuwali yomsebenzisi, imidwebo yezintambo, nemibiko ye-QC ngesiNgisi.
7. Shisa{1}}ukuhlola nokusebenza (isango lokugcina)
Yenza ukushisa kwamahora angu-8–24{2}ugijima ukuze uveze amaphutha akhona ngezikhathi ezithile. Ngesikhathi sokusha{4}, bheka ukuhluleka kweswishi/izinzwa, amaphutha omsindo/i-LED, nokuziphatha kwe-firmware okungazinzile.
Imiphumela yokungena futhi wamukele kuphela amaqoqo adlula ama-threshold achaziwe.
Amathiphu asebenzayo wokuthenga
- Oda amasampuli ngaphambi kwenqwaba:1–2 amayunithi esampula, yenza ukuhlola okugcwele futhi ushise-phakathi.
- Xoxisana ngamathuluzi & MOQ:lindela ukwehla kwentengo kumayunithi ayi-10–50; cela izingcaphuno ze-FOB ngokumelene ne-CIF kanye nesici sempahla nomsebenzi.
- I-QC yenkampani yangaphandle-sebenzisa ukuhlola okuzimele (isb, i-SGS, i-Bureau Veritas) ukuhlola{2}}ngaphambi kokuthunyelwa.
- I-SLA nezingxenye ezisele:chaza imigomo ye-RMA, izikhathi zokuhola zezinsimbi ezibalulekile (amamotho, ama-PCB) kanye nezindleko zokumiselela kunkontileka.
Imininingwane yokutholwa kwe-China
Sebenzisa imininingwane yolimi lwendawo futhi ugcizelele ekubhalweni kwesiNgisi. Ezingxenyeni ze-PCB, qinisekisa umsuka wengxenye kanye nokuthobelana kwe-RoHS/REACH uma udayisela i-EU. Ngempilo yemoto, cela amalogi okuhlola anamazinga okushisa alinganisiwe amanje nama-ambient. Ukupakishwa kufanele kuhlangabezane namazinga ekhreyithi yokuthekelisa ukuze kuvikelwe izimpahla ngesikhathi sohambo olude lwasolwandle.
