uluhlu lokujonga umgangatho we-coin pusher: ukuba uthenga i-coin pusher machines e-China, sukuqikelela-ukuhlola. Esi sikhokelo sophicotho-zincwadi esisebenzayo{2} sibonisa amanyathelo asixhenxe ayimfuneko kumaqela okuthenga: intembeko yokupakisha, ukuhlolwa kwe-PCB, uvavanyo lobomi bemoto, ihopper kunye nenkozo{3}}yokuhlolwa kwendlela, ulawulo lwe-firmware, uxwebhu kunye neendawo ezisecaleni, kunye nokutshisa{4} ekuqinisekiseni. Ekugqibeleni ungakhuphela i--ukusebenzisa{7}}ispreadsheet sokuhlola ukuze usebenze ngexesha lokujonga isampulu.
Kutheni kuqhutywa uphicotho lwefektri? (Yintoni injongo?)
Uphicotho lwefektri kunye nokuhlolwa kwesampulu kuthintela ukubuyiswa kweendleko, iintloko zewaranti, kunye nezikhalazo zabathengi. Ukufumana i-coin pusher, iimpazamo ezincinci (imoto ebuthathaka, i-dodgy PCB soldering, okanye ukhuseleko olubi lwekhreyithi) iguqulela kumdlalo olahlekileyo kunye nexesha lokuphumla emgangathweni wakho. Sebenzisa okuuphicotho lwemali yasefektriuluhlu lokutshekisha ukukhusela umda kunye nesidima.
1. Ukupakishwa kunye nokuhlolwa kwekhreyithi - kufuneka kujongwe ntoni (Yenziwa njani)
Qinisekisa amandla ekhreyithi yangaphandle, izikhuseli zekona, umqobo wokufuma, kunye namanqaku achanekileyo okuthumela ngenqanawa.
Vula ikhreyithi yesampulu: jonga i-cushioning yangaphakathi (ugwebu/i-ply), izahluli, kunye nokungashukumi. Ukupakisha okulambathayo kukhokelela kumonakalo wendlela{1}}uxwebhu oluneefoto.
2. I-PCB kunye nokuhlolwa kwe-elektroniki - iimpawu eziphambili zokubukela
Vavanya amalungu e-solder, ukubekwa kwecandelo, kunye ne-conformal coating. Amalungu abandayo e-solder, intsalela ye-flux, okanye izinto ezingekhoyo ziiflegi ezibomvu.
Qinisekisa iimpawu zecandelo kumacandelo abalulekileyo (i-voltage regulators, i-MOSFETs) kwaye ucele ingxelo yokuhlola ebonakalayo ye-IPC.
3. Uvavanyo lweMoto & nezixhobo zobomi - kutheni kubalulekile
Baleka imijikelo yobomi beemoto kwiiyunithi zesampulu (ecetyiswayo kwi-1,000–10,000 yemijikelo ngokuxhomekeke kwinkcazo) kwaye ulinganise umzobo wangoku. Ukugqithiswa kwangoku okanye ingxolo iqikelela ukusilela kwangethuba.
Cela umenzi wedatha ye-MTBF kunye neelog zovavanyo lwesampulu. Ukusilela "kobomi bemoto" ngoyena nobangela uphambili wokwehla kwexesha ebaleni.
4. I-Hopper, indlela yenkozo & iitshekhi zokuqinisekisa
Uvavanyo lwemali yenkozo kunye neemvaba ekujoliswe kuzo kunye neempawu; qinisekisa ukuba abenzi boluvo babhalisa ngokuchanekileyo kwaye izixhobo ze-hopper azijongi.
Qinisekisa abamkeli beebhili okanye iziqinisekisi ukuba zibandakanyiwe; jonga ulungelelwaniso kunye namazinga okulahlwa kobuqhophololo.
5. I-Firmware, ulawulo loguqulelo kunye noqwalaselo
Qinisekisa ukuba inguqulelo ye-firmware ihambelana ncakasana kwaye ibhaliwe. Cela inkqubo yohlaziyo lwe-firmware ekhuselekileyo kwaye ubuze ukuba isitshixo se-bootloader siyasetyenziswa na.
Qinisekisa iisetingi zeepesenteji zentlawulo kunye nokukhutshwa kwetikiti kufumaneka kuphela ngemowudi yenkonzo eqinisekisiweyo.
6. Uxwebhu, iindawo ezisecaleni kunye nokuleyibheli
Ifuna uluhlu lwamacandelo asecaleni ({0}}iirubha, iimotor, iifuse, iiglowubhu) kunye nokuleyibhelishwa kweziqhagamshelo zePCB. Ikhithi equkiweyo-yehlisa iMTTR.
Fumana iimanyuwali zomsebenzisi, imizobo yocingo, kunye neengxelo ze-QC ngesiNgesi.
7. Tshisa{1}}ngaphakathi & novavanyo olusebenzayo (isango lokugqibela)
Yenza iiyure ezi-8–24 zokutshisa{2}ubaleko ukuveza iziphene. Ngexesha lokutshisa -ngaphakathi, jonga iswitshi/ ukusilela kwesivamvo, iimpazamo zeaudio/zeLED, kunye nokuziphatha kwefirmware engazinzanga.
Loga iziphumo kwaye wamkele kuphela iibhetshi ezidlula imida echaziweyo.
Iingcebiso ezisebenzayo zokuthenga
- Odola iisampuli phambi kobuninzi:1–2 iiyunithi zeesampulu, qhuba uhlolo olupheleleyo kwaye utshise-ngaphakathi.
- Thetha ngezixhobo kunye ne-MOQ:lindela ukuhla kwexabiso kwiiyunithi ze-10-50; cela FOB vs. CIF ucaphulo kunye factor in imithwalo & duty.
- Iqela lesithathu - le-QC:sebenzisa uhlolo oluzimeleyo (umzekelo, iSGS, iBureau Veritas) ukulungiselela -itshekhi zangaphambili.
- I-SLA kunye neendawo ezisecaleni:chaza imimiselo ye-RMA, amaxesha okukhokela kwii-spares ezibalulekileyo (iimoto, ii-PCB) kunye neendleko zokutshintsha kwikhontrakthi.
Iimveliso zaseTshayina
Sebenzisa imilinganiselo yolwimi lwasekuhlaleni kwaye unyanzelise kumaxwebhu esiNgesi. Kumalungu e-PCB, qinisekisa imvelaphi yecandelo kunye nokuthotyelwa kwe-RoHS/REACH ukuba uthengisela i-EU. Kubomi bemoto, cela iilog zovavanyo ezinomlinganiselo wangoku kunye nobushushu be-ambient. Ukupakishwa kufuneka kuhambelane nemigangatho yekhreyithi yokuthumela ngaphandle ukukhusela iimpahla ngexesha lohambo olude lolwandle.
