Tuzashyiramo amakuru nyayo aturuka ku murongo wacu w'ibikorwa—nk'uko Igice cy'icyuma cya PCB 301-5.0—kugira ngo dugaragaze ibitagenda neza n'ibitagenda neza. Reka dutangire n'ishingiro: kugenzura ibintu.
1. Icyemezo cy'ibikoresho: Uretse ikarita y'umuhondo ya UL
Amakipe ashinzwe gutanga amasoko ntiyemera ikarita y'umuhondo ya UL ku giciro cyayo. Basaba raporo z'ibizamini by'ibikoresho byihariye (MTRs) kuri buri gice cya resin gikoreshwa mu nzu y'ibikoresho bya terminal block. Ku mazu yacu ya PA66, bivuze kugenzura amanota ya UL 94 V-0 yo gutwika hamwe n'amakuru nyayo y'ibizamini byo gutwika: igihe cyo gutwika nyuma y'umuriro kigomba kuba munsi y'amasegonda 10 kuri buri ngero, kandi nta matonyanga yo gutwika ashobora gutwika ikimenyetso cy'ipamba. Twabonye abagenzuzi banze itsinda kuko MTR yagaragaje matonganya 12 ku ngero imwe—nubwo impuzandengo yari amasegonda 8. Igipimo ngenderwaho ni kuri buri ngero, ntabwo ari impuzandengo.
Uretse gutwika, bagenzura ingano y'ibirahuri muri PA66. Ibipimo bisanzwe ni 30% ± 2% by'ibirahuri byuzuye kugira ngo bigerweho neza. Abagenzuzi bakoresha isesengura rya thermogravimetric (TGA) kugira ngo bemeze ibi. Iyo ingano y'ibirahuri igabanutse ikagera kuri 27%, igice gishobora kugorama mu gihe cyo gusodera, bigatuma pin ihinduka. Dufite ubushobozi bwo kugenzura buri gice mbere yo kohereza. Ku byuma bya terminal, amatsinda ashinzwe gutanga amasoko asaba isesengura rya spectrographic kugira ngo yemeze imiterere y'umuringa (ubusanzwe C36000 cyangwa C37700) ufite umuringa uri hejuru ya 57% n'ingano y'umuringa iri hagati ya 1.5% na 3.5% kugira ngo ibyuma bikoreshwe neza. Dutanga aya makuru muri twe. inyandiko z'ibicuruzwa kuri buri gutumiza ibintu byinshi.
Laboratwari zo hanze nka Serivisi zo gupima ibikoresho bya UL bikunze gukoreshwa mu kugenzura ibikoresho by’abandi. Amatsinda ashinzwe gutanga amasoko ashobora kandi gusaba raporo y’ibizamini byemewe na ISO 17025 muri laboratwari y’umutanga serivisi. Muri J-GUANG, dufite icyemezo cya ISO 9001:2015 kandi tubika inyandiko zo gupima ibikoresho byose byo gupima, abagenzuzi basuzuma mu gihe cyo gusuzuma uruganda.
2. Iyubahirizwa ry'ibipimo munsi ya mikorosikopi: Itegeko rya 0.1mm
Igenzura ry’ibipimo niho igenzura ry’ibipimo byinshi ribera ingano imwe. Amatsinda ashinzwe gutanga amasoko akoresha imashini zipima (CMM) cyangwa optique compparators kugira ngo barebe ingano y’ingenzi ku gipimo cy’ibice 125 kuri buri gice (kuri IEC 60512-1). Ku gice cy’inyuma cya 5.0mm, ingano y’ingenzi ni: intera y’aho inyura (5.0mm ± 0.2mm), umurambararo w’aho inyura (1.0mm ± 0.05mm), uburebure rusange (10.0mm ± 0.3mm), n’aho inyura hagati y’umwobo (≤0.1mm). Twabonye abagenzuzi banze itsinda kuko umurambararo w’aho inyura ku bipimo 3 kuri 125 wapimaga 0.94mm - 0.01mm munsi y’umupaka wo hasi w’ibipimo. Ubushobozi bwo kwihanganira ibintu ni ntagereranywa.
Ariko isuzuma nyaryo rireba aho umurongo uhurira: ubujyakuzimu bw'umugozi w'icyuma n'umwobo w'icyuma. Kuri moderi yacu ya 301-5.0, umugozi wa M2.5 ugomba kugira ubujyakuzimu bwa mm 4.0 ± 0.1, kandi umwobo w'icyuma ugomba kuba mm 2.5 ± 0.15. Abagenzuzi bakoresha ibipimo byo kugenzura. Niba ubujyakuzimu bw'umugozi ari buto cyane, umugozi ntuzatanga imbaraga zihagije zo gufunga insinga za AWG 14; niba ari buto cyane, umugozi ushobora kuva hasi no gukuraho. Twakusanyije imbonerahamwe yo kugereranya mu nyandiko zacu z'igenzura igaragaza igipimo gisanzwe cyo gutsinda/gutsindwa:
| Ingano | Umupaka w'Ibisobanuro | Igipimo cyo gutsinda (Umusaruro wacu) | Igipimo cyo kwangwa kw'inganda |
|---|---|---|---|
| Intera iri hagati y'aho bashyira ibibuga | 5.0mm ± 0.2mm | 99.8% | 2-5% |
| Umurambararo wa pini | 1.0mm ± 0.05mm | 99.5% | 3-7% |
| Ubujyakuzimu bw'umugozi wa screw | 4.0mm ± 0.1mm | 99.2% | 4-8% |
| Ifungura ry'insinga | 2.5mm ± 0.15mm | 99.6% | 2-6% |
| Umwobo wo hagati | ≤0.1mm | 98.9% | 5-10% |
Dufite sisitemu yo kugenzura imikorere y'ibarurishamibare (SPC) ikurikirana ibi bipimo mu gihe nyacyo mu gihe cyo gushushanya no gusiga kashe. Abagenzuzi bakunda kubona imbonerahamwe za SPC—bigaragaza ko turi abantu bashinzwe gukora, ntabwo ari abantu bashinzwe gukora. Kugira ngo umenye byinshi ku bijyanye n'uburyo bwacu bwo gukora ubuziranenge, reba incamake y'umurongo w'ibicuruzwa.
3. Isuzuma ry'amashanyarazi riri munsi y'umutwaro: Kurwanya Dielectric no Kurwanya Guhuza
Amakipe ashinzwe gutanga amasoko ntabwo agerageza gusa ibyuma bya terminal ku bushyuhe bw'icyumba. Apima ku bushyuhe buri hejuru (85°C mu masaha 1000 kuri IEC 60998-2-1) na nyuma yo guhumeka (95% RH mu masaha 48). Ibipimo bibiri by'ingenzi by'amashanyarazi ni voltage yihanganira dielectric na resistance yo gufata. Ku gice cya terminal gifite 300V, ikizamini cya dielectric ni 1500V AC mu gihe cy'umunota 1 nta gucika cyangwa umuvuduko w'amazi urenze 5mA. Twabonye abagenzuzi bakoresha 1800V mu masegonda 5 nk'ikizamini cy'ibanga - iyo binaniranye, igice cyose gishyirwa mu kato.
Ubudahangarwa bwo gukoraho bupimwa hakoreshejwe uburyo bwa Kelvin bufite insinga enye. Ubusanzwe, ingano yabyo ni ≤5 miliyohm, na ≤10 miliyohm nyuma y'amasaha 50 yo gushyiramo/gukuramo. Ariko dore ikibazo: amakipe ashinzwe gutanga amasoko akunze gupima akoresheje insinga nyayo (14 AWG stranded copper) aho gukoresha agapira ko gupima, kuko igikoresho cyo gupima insinga kuva kuri terminal ari cyo cy'ingenzi mu murima. Iyo imbaraga zo gufunga screw zidahagije, kudahangarwa no gukoraho bishobora kwiyongera kugeza kuri miliyohm 20 nyuma yo gushyuha. Dusuzuma buri gice mbere y'igihe dukoresheje amashanyarazi ya 10A mu masaha 1000 kugira ngo tumenye neza ko ibintu bihamye. Laboratwari zo hanze nka Serivisi za TÜV Rheinland tanga igenzura ryigenga ku baguzi babikeneye.
Igenzura rimwe twakoze umwaka ushize ryakozwe n'itsinda rishinzwe gutanga amasoko riturutse ku ruganda rukora inverter y'izuba. Bazanye ibikoresho byabo byo gupima maze bakora ikizamini cya dielectric cya 2000V ku bipimo 50. Byose byaratsinze, ariko basanze intera yo gucika ku gipimo cyacu cya 301-5.0 yari 6.2mm—iri hejuru ya 5.5mm nibura kuri dogere ya 2 ya 300V y'ihumana. Iyo nyongera y'amafaranga yaduhaye urwego rwo hejuru rw'abatanga serivisi. Gupima amashanyarazi si ugutsinda cyangwa gutsindwa gusa; ni ukugaragaza imbaraga z'igishushanyo.
4. Ubuziranenge bwo gutwikira no kurwanya ingese: Impatwe y'umunyu
Ibikoresho bya terminal block ubusanzwe biba ari umuringa ukozwe muri nikeli, bifite ubugari bwa mikoroni 2-5. Amatsinda ashinzwe gutanga amasoko arabigenzura akoresheje X-ray fluorescence (XRF) analyzers. Niba urwego rwa nikeli ruri munsi ya mikoroni 2, terminal ishobora kwangirika mu bidukikije bifite ubushuhe bwinshi, bigatuma habaho kwiyongera k'ubudahangarwa. Twabonye abagenzuzi banze itsinda aho ubugari bwa nikeli bwari mikoroni 1.8—nubwo spec yavuze mikoroni 2-5. Umupaka wo hasi ni ntagereranywa.
Ariko ikizamini nyacyo ni spray y'umunyu kuri ASTM B117. Ku bice by'inganda, amasaha 48 yo gusukura umunyu nta ngese itukura ku buso bw'aho terminal iherereye ni ibisanzwe. Ibipimo bimwe na bimwe by'urwego rw'imodoka bisaba amasaha 96. Dukora ibizamini byo gusukura umunyu kuri buri gice cy'umusaruro kandi dutanga raporo. Mu igenzura rimwe, itsinda rishinzwe gutanga amasoko ryo mu kigo cy'ibikoresho by'amashanyarazi cyo mu mazi ryasabye spray y'umunyu amasaha 120 - twatsinze nta ngese, ariko gusa kubera ko inzira yacu yo gusukura irimo nickel underlayer ya mikoro 3 nibura mbere yuko nickel irangira burundu. Ubwo bunini bw'inyongera budutwara hafi $0.002 kuri buri gice, ariko birakwiye ko byemezwa.
Abagenzuzi bagenzura kandi niba hari agace gafatana n'icyuma gikoresha kaseti (ASTM D3359). Iyo hari uduce dufatana tw'icyuma, icyuma kirakwanga. Twanogeje uburyo bwacu bwo gushushanya kugira ngo dushyiremo agace gafatana, kandi twandika imiterere y'ubwogero n'ubushyuhe kuri buri gihindutse. Kugira ngo umenye byinshi ku buryo bwo gushushanya, reba ibisobanuro bya tekiniki kuri urupapuro rw'ibicuruzwa.
5. Kwemeza ipaki: Si agasanduku gusa
Amabwiriza menshi y’ibice 50.000 bya terminal agomba gupakira kugira ngo birinde kwangirika mu gihe cyo kohereza no kubika. Amatsinda ashinzwe gutanga amasoko agenzura ibintu bitatu: kurinda static, imbogamizi z’ubushuhe, no gupfunyika mu buryo bwa mekanike. Ibice bya terminal bifite imiyoboro ya PA66 birahuzwa neza—iyo bishyizwemo >60% bya RH mu gihe kirenga amasaha 48, bishobora kwinjiza ubushuhe no gutera inenge zo gupfunyika (popcorning) mu gihe cyo gupfunyika mu mazi. Abagenzuzi bagenzura ko mu ipaki harimo agafuka gakingira ubushuhe gafite desiccant n’ikarita igaragaza ubushuhe. Iyo ikarita igaragaza umutuku (bigaragaza >60% bya RH), igice cyose kiranze.
Imiterere y'imitako yemezwa hakoreshejwe ibizamini byo gutonyanga: agasanduku k'ibice bya terminal kamanuka kuva kuri metero 1.2 kakajya hasi kuri sima. Iyo ibice birenga 1% byerekana imiturire yacitse cyangwa imisumari igoramye, imiterere y'ibipfunyika irananirwa. Dukoresha ifuro ryihariye rifite utubuto kuri buri murongo w'ibice bya terminal, kandi twatsinze buri kizamini cyo gutonyanga mu myaka itatu ishize. Amatsinda ashinzwe gutanga amasoko areba kandi niba ibipfunyika bya terminal bikoreshwa mu bikoresho by'ikoranabuhanga bigezweho. Dutanga imifuka ya ESD iyo tubisabye.
Gushyira ibirango ni ikindi kintu cyo kugenzura: buri gasanduku kagomba kuba gafite ikirango kirimo nimero y'igice, ingano, kode y'itariki, na nimero y'ibibanza. Barcode zigomba kuba zujuje ibisabwa na GS1-128 kuri sisitemu zo kubikamo ibintu zikora. Twabonye abagenzuzi banze kohereza ibicuruzwa kubera ko barcode yari yangiritse kandi idashobora gupimwa. Ni akantu gato, ariko ni ingenzi mu bijyanye n'ibikoresho byinshi.
6. Inyandiko Kurohama mu buryo bwimbitse: Gukurikirana kuva kuri Resin kugeza ku byoherejwe
Amakipe ashinzwe gutanga amasoko arashaka gukurikirana buri gice cy’ububiko kugeza ku giciro cyacyo cy’ibikoresho fatizo. Ibyo bivuze ko igenzura rikubiyemo isuzuma ry’uruhererekane rw’inyandiko zose: icyemezo cy’isesengura ry’umutanga resin (CoA), ibipimo by’imashini zibumba (ubushyuhe, umuvuduko, igihe cy’urugendo), inyandiko zo kubungabunga ibyuma, ibiti byo koga, na raporo za nyuma z’igenzura. Dufite sisitemu yo gukurikirana ikoranabuhanga aho buri nomero y’ububiko ihuzwa n’izi nyandiko zose. Abagenzuzi bahitamo ku buryo butunguranye nomero y’ububiko maze bakadusaba gukuramo inyandiko mu minota 15. Ntitwigeze dutsindwa muri iki kizamini.
Kimwe mu byagaragaye mu igenzura ni ukubura inyandiko zo gupima amashanyarazi zakoreshejwe mu gushyiraho imbaraga zo gufunga ibyuma. Iyo amashanyarazi adapimwe mu mezi 12 ashize, umusaruro wose urakekwa. Dupima buri mashini buri mezi 6 kandi tugakomeza kwemeza. Mu buryo nk'ubwo, CMM ikoreshwa mu igenzura ry'ibipimo igomba kuba ifite icyemezo cyo gupima amashanyarazi gisanzwe gishobora gukurikiranwa na NIST cyangwa ikindi kigereranyo. Dutanga kopi mu gihe cy'igenzura.
Amatsinda ashinzwe gutanga amasoko anasuzuma raporo zacu z’ibyakozwe ku buryo bunyuranyije n’amategeko (NCRs) mu mwaka ushize. Barashaka kureba ko twamenya impamvu nyamukuru no gushyira mu bikorwa ingamba zo gukosora. Urugero, twagize NCR umwaka ushize aho umurambararo w’agapira wazamutse ukagera kuri 0.96mm bitewe no kwangirika kw’agapira. Twanditse impamvu nyamukuru (agapira kambara nyuma y’amasaha 500.000), igikorwa cyo gukosora (agapira kasimbuwe n’igenzura ryinyongera kuri buri masaha 10.000), n’igenzura (ibice 10.000 bikurikira byose biri mu bipimo). Urwo rwego rw’ibisobanuro rwubaka icyizere. Amasoko yo hanze nka Sisitemu zo gucunga ubuziranenge za ISO 9001:2015 tanga urwego rw'iyi nyandiko.
7. Ubushobozi bwo gukora mu nyubako: Incamake y'uruganda
Intambwe ya nyuma y'igenzura ni isuzuma ry'imiterere y'urwego rw'umusaruro. Amatsinda ashinzwe gutanga amasoko areba ibintu bitanu: isuku, kubungabunga ibikoresho, amahugurwa y'abakora, gutunganya akazi, n'umutekano. Ahantu handuye ho gushushanya hamwe n'amavuta yamenetse hasi ni ikimenyetso cy'umutekano - bigaragaza ko hari uburyo budakora neza. Dufite sisitemu ya 5S (Gutondeka, Gushyiraho gahunda, Kurabagirana, Gutunganya, Gukomeza) kandi abagenzuzi bakunze gufata amafoto kugira ngo bagereranye n'uburyo bwacu bwanditse.
Inyandiko z'ibikorwa byo gusana ibikoresho zirasuzumwa: ese imashini zibumba zifite gahunda yo kuzisana mbere yo kuzikoresha? Ese imashini zishyiraho sitampu zirasuzumwa nyuma ya buri nshuro 100.000? Tubereka inyandiko zacu zo gusana, zirimo kugenzura amavuta ya buri munsi n'ibipimo bya buri cyumweru byo kwambara. Inyandiko z'amahugurwa y'abakoresha nazo zirasuzumwa—buri mukoresha agomba kuba afite icyemezo cy'ubuhanga ku bwoko bw'imashini ye. Dutanga amahugurwa buri mwaka kandi tugakomeza gukoresha imbonerahamwe y'ubumenyi.
Imikorere y'akazi ni ingenzi: ibikoresho fatizo bigomba kuba bifite ikirango gisobanutse kandi bitandukanyijwe n'ibicuruzwa byarangiye. Dukoresha ibisanduku bifite ibara: icyatsi kibisi iyo bigenzuwe kandi byemejwe, umuhondo iyo bishyizwe mu kato, umutuku iyo byanze. Abagenzuzi bagenzura ko ahantu ho gufungirwa hafunzwe kandi ko abakozi bemewe ari bo bonyine bafite uburenganzira bwo kwinjira. Umutekano ntushobora kuganirwaho: guhagarara byihutirwa ku mashini zose, kuzimya umuriro bifite ibirango byo kugenzura buri kwezi, hamwe no kubahiriza amategeko agenga umutekano. Twatsinze buri igenzura ry'umutekano kuko tubifata nk'agaciro k'ingenzi, ntabwo ari agasanduku k'igenzura.
Itsinda rimwe rishinzwe gutanga amasoko ryo mu kigo cy’i Burayi gishinzwe ikoranabuhanga ryamaze umunsi wose ku igorofa ryacu, rigena buri ntambwe y’ibikorwa kandi riyigereranya n’igihe cy’izunguruka ryanditse. Basanze igihe nyacyo cyo gushushanya inzu ya 301-5.0 cyari amasegonda 28, ugereranyije n’amasegonda 30 yanditse. Icyo kigereranyo cy’amasegonda 2 cyabahaye icyizere mu bushobozi bwacu bwo kuzuza ibyo batumije by’amayuniti 100.000 mu byumweru 4. Inzira si iyo gushaka ibibazo gusa—ni iyo kugenzura ko umutanga serivisi ashobora gusohoza ibyo yasezeranye.
