Kubadwa ndi kukula kwa mphamvu yotsimikiziridwa yadzidzidzi

Mu 2003, ndi kukhazikitsidwa kovomerezeka kwa Phenix Lighting, tinayambitsa R&D ya ballast yoyamba yadzidzidzi yadzidzidzi padziko lonse lapansi monga momwe kasitomala wakunja amafunira mphamvu yamphepo.Ndi kuzama mosalekeza kwa kafukufuku ndi chitukuko, pamodzi ndi kugonjetsa mavuto luso, ife kwambiri anamva m'munda wa kuunikira mwadzidzidzi, makamaka makasitomala apamwamba mu msika North America, kokha akatswiri kwambiri kafukufuku ndi chitukuko luso ndi zokwanira odalirika mankhwala. ntchito ikhoza kupambana kupulumuka pamsika uno.Zomwe zimafunikira pamsika zimagwirizananso ndi lingaliro lathu lachitukuko la "kupanga zinthu zabwino kwambiri".

Kuyambira pamenepo, timadzipereka mwalamulo pakupanga ndi kupanga zinthu zowunikira mwadzidzidzi.Kupyolera mu zaka 20 za kufufuza kosalekeza ndi kuyesa, mpaka pano, takhala ndi mphamvu zowonjezera mphamvu zamagetsi zadzidzidzi kuphatikizapo.Woyendetsa mwadzidzidzi wa LEDndiMini inverter mwadzidzidzi.

Munthawi yayitali iyi yazaka 20, mndandanda watsopano uliwonse unayambika, zobisika kuseri kwa chochitika chosaiwalika.

Kuzungulira kwachitukuko chamagetsi adzidzidzi ndiatali kwambiri, osati chifukwa chakuti mapangidwe amagetsi amagetsi ndi ovuta, amaganiziranso kuti pamafunika nthawi yaitali kuti atsimikizire kuthekera kwa chiwembucho, kuyesa kudalirika kwa zigawo ndi kuyesa kulimba monga kutsika ndi kutsika. kutentha kwachakudya-kutulutsa kuzungulira.

Mugawo la Design Verification Process (DVP), tidzaphatikizana ndi zofunikira za DFMEA (Design Failure Mode and Effects Analysis), ndikuyang'ana mwatsatanetsatane zoopsa zosiyanasiyana zomwe zingakhalepo panthawi ya mapangidwe.Zitsanzo zoyamba za DVP ziyenera kudutsa mazana azinthu zoyesa.Kupyolera mu kusanthula mozama kwa zotsatira za mayesero aliwonse, ntchito ya mankhwala imatsimikiziridwa.Ngati chimodzi mwa zizindikiro zaumisiri chikulephera kukwaniritsa zofunikira, zinthu zonse zoyesedwa ziyenera kuyambiranso mutatha kukonza.Kupyolera mu dongosolo lokhwima loterolo, kuopsa kwa mankhwala atsopano kumathetsedwa chimodzi ndi chimodzi.

Pambuyo pomaliza kuyesa kwa zitsanzo za DVP ndi kuyesa kuvomereza, kuyesa kwa DVP (Design Verification Process) kumafunika.Magawo a SMTs ndi mapulagi-ins amachitika mumisonkhano yopitilira 100,000 yopanda fumbi.Mitundu yonse ya jigs ndi zokonza ziyenera kukhalapo, ndipo kutentha kwa ng'anjo kuyenera kuyeza bwino kuti gawo lililonse la bolodi la dera likutenthedwa mofanana ndipo mgwirizano uliwonse wa solder ndi wolimba popanda kuwononga zigawo zikuluzikulu.PCBA ikatha, bolodi lililonse lidzadutsa mayeso a parameter yamagetsi, ndipo zizindikiro zosiyanasiyana zikakwaniritsidwa, msonkhano ndi ukalamba udzachitika.Asanayambe kuyezetsa ukalamba, nthawi 20 zoyeserera zozimitsa zidzachitika.Ndiyeno 5 ma voltages a kulipiritsa ndi kutulutsa mkombero mayeso adzachitidwa kwa sabata kuti aone kulolerana kwa mankhwala ndi zigawo zikuluzikulu potsiriza.Pambuyo pake, zoyeserera za DVP zidzayesedwa kwambiri komanso kutsika kwa kutentha mu labotale ya R&D, yomwe ipitilira pafupifupi miyezi isanu ndi umodzi.

Pambuyo pakuyesa bwino kwa DVP, kuyesa koyamba kwa PVP (Production Verification Process) kudalowetsedwa mwalamulo.Mosamalitsa malinga ndi PFMEA (Process Failure Mode Effects Analysis) pambuyo pa kuchuluka kwa kusanthula kwachiwopsezo, tchulani njira ya DVP ndiyofanana ndendende, mpaka kumapeto kwa mayeso a 5 voltage charge-discharge cycle test.Ndikofunikira kuyang'ana kulondola komanso kusasinthika kwa zida zomwe zikubwera, komanso ngati zinthu zonse monga munthu, makina, zinthu, njira ndi chilengedwe ndizolondola popanga.Pambuyo pakuchita bwino kwa PVP Trial Production, kupanga madongosolo ambiri kumatha kuvomerezedwa.

Dongosolo lililonse la batch limayesedwa 100% yamagetsi asanaperekedwe ndipo amayesedwa kukalamba kwamagetsi asanu pambuyo pa msonkhano.Kupyolera mu kutsimikizira kokwanira ndi kuyesa, onetsetsani kuti chinthu chilichonse choperekedwa kwa makasitomala ndi chapamwamba kwambiri.
