Kungani amabhokisi okuthumela izinto zikagesi angenakunyakaziswa edingeka kakhulu
Uchungechunge lokuhlinzekwa kwezingxenye ze-semiconductor kanye neze-elekthronikhi emhlabeni wonke lusebenza ngaphansi kwengcindezi enkulu ukuze lugcine amazinga angenaphutha ngenkathi lulawula izindleko zokuthutha ezikhulayo. Njengoba ama-node e-semiconductor encipha futhi izinhlangano zebhodi lesifunda eziphrintiwe (ama-PCBA) ziba nzima kakhulu, ukuzwela kwalezi zingxenye ekukhishweni kwe-electrostatic (ESD) kanye nokushaqeka ngokomzimba kuyanda. Ngenxa yalokho, amaqembu okuthenga kanye nabaqondisi bezokuthutha bashintsha ngokushesha ekupakisheni okusetshenziswa kanye baye emabhokisini okuthumela e-elekthronikhi asebenza kanzima, angasetshenziswa kabusha aklanyelwe ngqo ukuthuthwa ngobuningi. Izitsha ezinkulu ezigoqekayo ezingaguquki (ama-FLC) kanye namaphakethe emikhono kuvele njengesisekelo sezokuthutha ze-elekthronikhi zesimanje, okunikeza inhlanganisela ekhethekile yobuqotho besakhiwo kanye nokuvikelwa kwe-elekthronikhi.
Isidingo salezi zibhokisi zokuthumela ze-elekthronikhi ezikhethekile sisheshiswa kakhulu yi-regionalization eqhubekayo yokukhiqiza i-semiconductor. Njengoba izimboni ezinkulu zokukhiqiza (izindwangu) zanda kulo lonke elaseNyakatho Melika, eYurophu, naseNingizimu-mpumalanga ye-Asia, inani lokuthuthwa kwezikhungo ezahlukene—ukuthutha ama-wafer angavuthiwe, ama-substrate, nama-microchip aqediwe phakathi kwezindwangu, izindawo zokuhlola, nezindawo zokuhlanganisa—likhuphuke kakhulu. Lezi zintambo zokuhlinzeka ezivaliwe zidinga ukupakishwa okungasinda iminyaka yemijikelezo yezokuthutha ngenkathi kugcinwa ngokuqinile amapharamitha e-ESD. Izitsha ezigoqekayo ezilwa ne-static zibhekana nalesi sidingo ngokunikeza isivikelo esiqinile ngesikhathi sokuthunyelwa okuphumayo futhi ziwa zibe yingxenyana yevolumu yazo ehlanganisiwe ukuze kulungiswe izinto ezibuyela emuva ezingabizi kakhulu.
Ngaphezu kwalokho, imiyalelo yezemvelo, ezenhlalo, kanye nokuphatha (i-ESG) iqhuba abathengi abathengisa ngobuningi ukuba basuse izinto ezibolile ezisetshenziswa kanye kumanethiwekhi abo. Ukupakisha okungabizi akugcini nje ngokukhiqiza imfucuza enkulu kodwa futhi kungenisa amazinga angamukeleki okungcola kwezinhlayiya ezindaweni ezihlanzekile. Izitsha zepulasitiki ezigoqekayo ezingaguquki zinikeza enye indlela eqhubekayo, ehlanzekile, nelawulwa kakhulu. Ngokunciphisa izindleko zokuqala zemali eminyakeni engamakhulu yemijikelezo yokunikezela, abasabalalisi bebhizinisi kanye nabakhiqizi bemishini yokuqala (ama-OEM) bathola ukwehla okukhulu kwezindleko zobunikazi (i-TCO) ngenkathi beqinisekisa ubuqotho bemithwalo yempahla kagesi enenani eliphezulu.
Izidingo ezibalulekile ze-ESD kanye nokuphathwa kahle
Ku-semiconductor logistics, ukupakisha kumele kuvimbele ngenkuthalo ukukhiqizwa kukagesi ongashintshi (i-tribocharging) futhi kususe ngokuphephile noma yiziphi izindleko ezenzekayo. Amabhokisi okuthumela ama-elekthronikhi kumele alandele amazinga aqinile omhlaba wonke, ikakhulukazi I-ANSI/ESD S20.20 kanye ne-IEC 61340-5-1. Lezi zindinganiso zithi izinto zokupakisha kumele zibe semazingeni athile okumelana nomphezulu kuye ngokuthi zisetshenziswa kanjani. Ngokuvamile, izinto ezihlakazekayo—ezisukela ku-$10^5$ kuya ku-$10^{11}$ ohms—zithandwa kakhulu ezitsheni ezinkulu, njengoba zinciphisa ukukhishwa kukagesi ongashintshi, zivimbela ama-arcs angazelelwe, abhubhisa ama-microprocessor abucayi. Izinto ezihambisa umoya kakhulu (ezingaphansi kuka-$10^4$ ohms) zingasetshenziswa ekuvikeleni kwangaphakathi okuthile kodwa zibeka ingozi yokukhishwa ngokushesha okukhulu uma idivayisi eshajiwe ithintana ngqo.
Ngaphandle kokulawulwa kwe-ESD, ukuphathwa okuhlanzekile kuyisidingo esingaxoxiswana ngaso samaketanga okuhlinzeka nge-semiconductor. Ukupakisha okungena emagumbini okuhlanza e-ISO Class 5 kuya ku-ISO Class 7 akukwazi ukukhipha izinhlayiya, ukukhipha ama-organic compounds aguquguqukayo (ama-VOC), noma ukugcina ukungcola kwezinto eziphilayo. Amabhokisi endabuko ahlanganisiwe, noma ngabe aphathwa ngezingubo ezilwa nokungaguquguquki, akhiqiza uthuli lwephepha ngokungqubuzana nokuwohloka. Izitsha ezigoqekayo ze-polyethylene ephezulu (i-HDPE) noma i-polypropylene (PP), ezihlanganiswe nama-polymers ahlala njalo anganyakazi noma i-carbon black, zisusa ukuchithwa kwezinhlayiya. Ngaphezu kwalokho, lezi zitsha zepulasitiki zingahlanzwa ngokuphindaphindiwe kusetshenziswa izindlela ezikhethekile zokusula ikamelo lokuhlanza ngaphandle kokubeka engcupheni izakhiwo zazo zesakhiwo noma ze-electrostatic, ukuqinisekisa ukuthi zihlangabezana nemingcele yokuhlanzeka eqinile edingwa yizinkampani ze-semiconductor zesigaba sokuqala.
Izimo ze-semiconductor kanye ne-electronics ezifanelana kahle kakhulu

Isimo esiyinhloko ukuthuthwa kwama-wafer e-semiconductor phakathi kwezitshalo zokukhiqiza ezingaphambili kanye nezindawo zokuhlanganisa nokuhlola ze-semiconductor ezingaphandle ezisebenzisa i-back-end. Kulezi zindlela, ama-pallet ajwayelekile ama-wafer pod asindayo, abuthakathaka adinga ukuvikelwa okuqinile komjikelezo kanye nonyawo olujwayelekile lwesitsha esikhulu esiphephile se-ESD. Uhlobo lokugoqeka luvumela izitsha ezingenalutho ukuthi zibuyiselwe ku-fab ngesilinganiso sokuhlanganiswa esingu-3:1 noma esingu-4:1, okunciphisa kakhulu izindleko zokubuyisela impahla.
Esinye isimo esingcono kakhulu sokusetshenziswa ukuthunyelwa ngobuningi kwamayunithi okulawula kagesi ezimoto (ama-ECU) kanye nezinhlelo zokuphatha amabhethri (ama-BMS) emigqeni yokuhlanganisa izimoto. Ukukhiqizwa kwezimoto kusebenza ngezimiso eziqinile ze-Just-In-Time (JIT), ezidinga ukupakishwa okujwayelekile okuhlangana kalula nezimoto eziqondiswa ngokuzenzakalelayo (ama-AGV) kanye nezinhlelo zokulayisha amarobhothi. Amabhokisi amakhulu okuthumela kagesi agoqekayo afakwe i-dunnage ye-thermoformed evikelekile ye-ESD ethwala ngokuphephile izinkulungwane zama-ECU ngephalethi ngalinye. Umthamo womthwalo osindayo walezi zitsha usekela isisindo esinzima sama-electronic ezimoto, kuyilapho iminyango eseceleni ivumela opharetha abaseceleni komugqa ukufinyelela okuqondile ezingxenyeni ngaphandle kokususa isitsha endaweni yokubeka impahla.
Imininingwane yobuchwepheshe okufanele iqhathaniswe
Uma kuhlolwa ukuthengwa kwamabhokisi okuthumela ngobuningi kwama-elekthronikhi, imininingwane yobuchwepheshe inquma kokubili ukusebenza kahle kwempahla kanye nokuphepha komthwalo we-elekthronikhi. Amaqembu okuthenga awakwazi ukuthembela kudatha ejwayelekile yobukhulu; kumele ahlole ubunjiniyela besitsha. Ukwakheka kwesakhiwo sezitsha ezinkulu ezigoqekayo kunquma ukuthi zizomelana kahle kangakanani namandla ashukumisayo empahla yamazwe ngamazwe, ukuphathwa kwe-forklift, kanye nokufakwa kwempahla yokugcina impahla, konke lokhu ngenkathi kugcinwa isivikelo se-electrostatic esiqhubekayo esizungeze okuqukethwe.
Isici esibalulekile sokuqhathanisa imininingwane ukuqonda umehluko phakathi kokwelashwa okulwa nokungaguquguquki kwezinto ezisetshenziswa endaweni ethile kanye nezinto ezihambisa umthamo. Izitsha ezishibhile zingasebenzisa ama-surfactant asetshenziswa endaweni ethile adonsela umswakama emoyeni ukuze adale ungqimba olungaphezulu oluchithayo. Kodwa-ke, lezi zingubo ziyaguga ngokuhamba kwesikhathi, zigezwe ngesikhathi sokuhlanza, futhi zihluleke ngokuphelele ezindaweni ezinomswakama ophansi (njengezindawo zokugcina izimpahla ezilawulwa yisimo sezulu noma amakamelo okuhlanza omile). Amabhokisi okuthumela kagesi asezingeni lezimboni athembele kuma-polymer ahlala njalo, achithayo ngokwemvelo noma amapulasitiki agcwele ikhabhoni lapho izakhiwo ze-ESD zibunjwa khona zibe yisakhiwo sama-molecule sezinto, okuqinisekisa ukusebenza kahle kwempilo yonke kungakhathaliseki ukuthi kunomswakama ongakanani.
Ngaphezu kwalokho, abathengi kumele bahlole ubunjiniyela bemishini yezindlela zokugoqa. Ama-hinge, ama-latches, kanye ne-sidewall interlocks yizona zinto ezivame kakhulu ukwehluleka ekupakishweni okusetshenziswa kabusha. Izitsha ezisezingeni eliphezulu zisebenzisa ama-hinge ahlanganisiwe, izimbambo eziqinisiwe, kanye nezigijimi ezingashintshwa. Ukuqhathanisa lezi zincazelo zobuchwepheshe kuqinisekisa ukuthi imikhumbi ekhethiwe yezitsha izosinda umjikelezo wokuphila weminyaka emihlanu kuya kweyisikhombisa ohlosiwe ngaphandle kokunqotshwa ukwehluleka kwemishini ngaphambi kwesikhathi noma ukuwohloka kwe-ESD, ngaleyo ndlela kuvikelwe ukutshalwa kwezimali okuphelele.

Ngaphezu kwalokho, abathengi kumele bahlole amandla okukhiqiza kanye nobunikazi bamathuluzi. Ama-FLC amakhulu adinga imishini yokubumba eningi, enamathani amaningi. Abahlinzeki kumele babonise amandla okuhlangabezana nezidingo zevolumu ephezulu futhi baphathe inani elincane le-oda (ama-MOQ) elihambisana nesu lokukhishwa komthengi. Kubalulekile futhi ukuqinisekisa ukuthi umhlinzeki ungumnikazi wemikhiqizo yokubumba noma yokukhipha imikhiqizo yangaphandle, njengoba ukusebenzisana ngqo nomkhiqizi kuqinisekisa ukulawulwa okungcono kokuhlanganiswa kwe-resin ngokwezifiso, izikhathi zokuhola, kanye nokusekelwa kwewaranti yangemva kokuthengisa kwezingxenye ezishintshwayo njengezihinge kanye neminyango yokuwasha.
Indlela yokuqinisekisa ukusebenza kwe-ESD kanye nokuhambisana nezinto ezibonakalayo
Ukuqinisekisa ukusebenza kwe-ESD kudinga izindlela zokuhlola ezijwayelekile. Amaqembu okuthenga kufanele agunyaze ukuthi abahlinzeki bahlole izinto ngokuvumelana ne-ANSI/ESD STM11.11 ukuze bathole ukumelana nobuso kanye ne-ANSI/ESD STM11.31 ukuze bathole ukusebenza kokuvikela. Ithuluzi eliyinhloko lokuqinisekisa yi-megohmmeter (evame ukubizwa ngokuthi imitha yokumelana nobuso) ehlonyiswe ngama-probe endandatho angamakhilogremu amahlanu. Lapho ethola i-prototype noma i-batch entsha, amaqembu e-QA kumele ahlole amaphuzu amaningi esitsheni—kufaka phakathi isisekelo, izindonga eziseceleni, kanye nama-hinge—ukuqinisekisa ukuthi ukumelana okufanayo kuphakathi kuka-$10^5$ no-$10^{11}$ ohms, okuqinisekisa ukuthi azikho “izindawo ezifile” ezivikelayo.
Ukuthobela izinto ezibonakalayo kudlulela ngale kokulawulwa okungaguquki. Abathengi kumele badinge amadokhumenti afakazela ukuthi izingxube ze-polymer azinazo izinsimbi ezisindayo nama-phthalates anqunyelwe ukuze zihambisane ne-RoHS kanye ne-REACH.
- Isitifiketi Sokuhambisana (i-CoC): Kumelwe kuhambisane nakho konke ukuthunyelwa, kuchazwe ngokucacile isithasiselo se-ESD esisetshenzisiwe (isb., i-carbon black noma i-IDP).
- Ukuhlolwa Kokubola Okungaguquki: Ukuqinisekiswa kokuthi izinto zingasusa ishaja engu-1,000-volt ibe ngaphansi kwama-volts angu-100 ngaphansi kwemizuzwana engu-2.0 (ngokwe-MIL-PRF-81705D noma amazinga afanayo).
- Ukuhlolwa Kokugeza: Ukuze kuqinisekiswe izakhiwo ze-ESD ezihlala njalo, abathengi kufanele bacele ukuthi isitsha sesampula sigezwe ngezinsipho zezimboni noma i-isopropyl alcohol bese siphinde sihlolwe ukuqinisekisa ukuthi ukumelana nomphezulu akuwonakali, okungaveza ungqimba oluyinkohliso lwendwangu.
Ukuqaliswa kwabasabalalisi namaqembu okuthenga
Ukuthola amabhokisi okuthumela e-elekthronikhi afanele kuyisigaba sokuqala nje; ukuqaliswa okuphumelelayo kusho imbuyiselo yokugcina ekutshalweni kwezimali. Kwabasabalalisi namaqembu okuthenga, ukuhlanganisa imikhumbi emisha yeziqukathi ezingagoqeki ezingaguquki kudinga ukuhlanganiswa okusebenzayo phakathi kwempahla, imisebenzi yokugcina impahla, kanye nokulawulwa kwekhwalithi. Ukushintsha kusuka ekupakisheni okusetshenziswayo kuya echibini lempahla elingasetshenziswa kabusha kudinga ushintsho endleleni yokusebenza. Lezi ziqukathi azisezona izinto ezisetshenziswayo ezilahlwayo; ziyimpahla eyinhloko elandelwayo okumele iphathwe, inakekelwe, futhi ibuyiselwe ngendlela efanele.
Ingxenye ebalulekile yokusetshenziswa ukulandelela impahla. Ngenxa yokuthi izitsha ze-ESD ezigoqekayo ezisezingeni eliphezulu zimelela ukutshalwa kwezimali okukhulu, ukulahlekelwa (ukuncipha) ngaphakathi kweketanga lokuhlinzeka kungabhubhisa ngokushesha i-ROI ebikezelwe. Amaqembu okuthenga kufanele acacise ukufakwa kwamathegi e-RFID noma amabhakhodi e-1D/2D ahluke kakhulu ngesikhathi senqubo yokukhiqiza. Ngokuhlanganisa lezi zihlonzi zokulandelela ne-Warehouse Management System (WMS) yenkampani noma isofthiwe ye-Enterprise Resource Planning (ERP), abaphathi bezokuthutha bangaqapha izindawo zezitsha, balandelele ukubalwa kwemijikelezo, futhi baphoqelele izivumelwano zokubuyisa nabalingani abangaphansi noma izikhungo ze-OSAT.
Ukuhlolwa kwendiza kuyibhuloho elibalulekile phakathi kokuthengwa kanye nokuqaliswa okugcwele. Ngaphambi koku-oda imikhumbi yamayunithi ayi-10,000, abasabalalisi kufanele basebenzise uhlelo lokuhlola lwendawo oluneziqukathi eziyi-100 kuya kwezingama-500. Lesi sigaba sokuhlola sivumela ithimba lokusebenza ukuqinisekisa ukusebenza kweziqukathi ezimweni zangempela—ukuhlola ukuthi zingena kanjani emalorini ezokuthutha esifunda, ukuthi zixhumana kanjani kahle nemishini ezenzakalelayo eseceleni komugqa, nokuthi izakhiwo ze-ESD ziyakwazi yini ukuhambisana nezimo zangempela zokuhamba. Idatha eqoqwe ngesikhathi sokuhlola iqinisekisa ukuthi noma yikuphi ukulungiswa okudingekayo ezinqubweni zokugcinwa kwempahla zangaphakathi noma zokuphatha kwenziwa ngaphambi kokuba kuqedwe ukuzibophezela okukhulu kwezimali.
Izinyathelo zokuphatha ukupakisha nokugcina impahla ngendlela eqhubekayo
Ukulinganisa izinqubo zokupakisha nokuphatha kubalulekile ukuvimbela umonakalo ongokoqobo ezitsheni nokuqinisekisa ukuphepha okuqhubekayo kwe-ESD.
Izinto Ezibalulekile Okufanele Uzicabangele
- Imiphumela yokuthengwa kwempahla ngobuningi kanye nochungechunge lokuhlinzekwa kwempahla kumabhokisi okuthumela e-elekthronikhi
- Imininingwane, ukuthobela imithetho, kanye nemigomo yezentengiselwano abathengi okufanele bayiqinisekise
- Izincomo ezisebenzayo zabasabalalisi namaqembu okuthenga
imibuzo ejwayelekile ukubuzwa
Kungani kufanele usebenzise izitsha ezigoqekayo ezingashukumi ukuze kusetshenziswe izinto ze-semiconductor logistics?
Zihlanganisa ukuvikelwa kwe-ESD, ukumelana nokushaqeka, kanye nomthamo wobuningi obungasetshenziswa kabusha. Imiklamo egoqekayo iphinde yehlise ivolumu yokubuyisa engenalutho, isiza ama-fabs nama-OEM ukunciphisa imfucuza yempahla kanye neyokupakisha.
Yiluphi uhla lwe-ESD oluvame ukufanela amabhokisi okuthumela izinto zikagesi?
Ngokuthuthwa kwe-bulk semiconductor, izinto zokuhlakaza ezicishe zibe yi-10^5 kuya ku-10^11 ohms zivame ukuthandwa ngoba zilawula ukushaja ngokuphephile ngaphandle kokukhishwa ngokuzumayo.
Ingabe izitsha zepulasitiki ezigoqekayo zingcono kunezibhokisi ezigoqekile ezindlini ezihlanzekile?
Yebo. Izitsha ze-HDPE noma ze-PP ezilwa nokungaguquguquki zikhipha izinhlayiya ezimbalwa, zingahlanzwa ngokuphindaphindiwe, futhi zilungele kangcono ukuphathwa kwe-ISO Class 5 kuya ku-7 kuneziphakeji ezihlanganisiwe.
Yiziphi izinhlelo zokusebenza ze-elekthronikhi ezifanela kangcono izitsha ezinkulu ze-ESD ezigoqekayo?
Zilungele ukudluliselwa kwe-wafer pod, ukunyakaza kwe-PCBA, kanye nokuthunyelwa ngobuningi kwama-ECU noma amayunithi e-BMS kumaketanga okuphakelwa avaliwe ane-logistics ebuya njalo.
Yiziphi izici okufanele abathengi baziqhathanise emabhokisini amakhulu okuthumela izinto zikagesi?
Hlola ukuhambisana kwe-ESD, ukuhambisana kwegumbi lokuhlanza, umthamo womthwalo, isilinganiso sokugoqa, ukulinganisa kwezinyawo, izinketho zokuhlobisa ngokwezifiso, kanye nezici zokufinyelela ezifana neminyango yokuphonsa yokukhetha ohlangothini lomugqa.
