Kubhala: Michael Macpherson Ukulola Kwezityhili Ngokusebenza
Ngokusho, ukudibana ngaphandle lokuthi uqondile ngenjalo njengoba yindawo yakho yokugcina okanye yesithombe siyazi ngayo? Ukufakwa kuyenza ngokubona ngamandla emnintini kunye nezicathulo ezifakelwe ngokuphucwayo. Ukufakwa kwenza into engumthi wendlela esingazange lento yicala lokuba amandla angasemva kwindawo yakheyo. Ngaphezulu, ukufakwa kukho imininingwane eyayiphiwe ngazo lapho abantu bafuna ukusebenzisa amandla apha ukubulawa kwezi zinto eziphakeme, kodwa zihlala zikhona umoya omncedisiyo nokukhetha isenzo sokuqalaba. Ukungena ndawonye - uphinde ubuyekeziswa ukuba alenze into leyo ngendlela enkulu, kodwa kusetyenziswa ngokubanzi kwaye nokuhlola lokulandelwa.
Ukufakamalaza kokuthiwa ngokwesiqhina sokuqala lokugcina iVacuum reflow ngokuba iyenza imibuzo yezilondolozi ezidingekayo. Ukudla kwesikhathi esisodwa kwaye akusetyenziswa ngephandle flame noma uphawu oluhlupheka njengezinto zokusetyenziswa ezintsha, iVacuum reflow usebenzisa isikhatsi esihlatyweyo ukuthola amabuzo amadingekayo. Lolu hlobo lwe technology lingazipha ukuthi amaxwebhu angaphumelele kakhulu kunye nokuthi aziphathe umoya weminyaka, okungafanele ukufakelwa nokuthi kuhluke izinyathelo.
Kwaye lokhu ngaphandle ifakazano elinye kwe vacuum reflow - ukuba ungenziwe ngokupheleleyo isolda paste. Ngokugxuma kwevacuum, isolda esingasetyenziswa sihlatywa ngesikhathi esifaneleyo kunye nokungafunekayo umoya wokuhlala ngaphandle komoya omphumeleyo! Lokho kuhlela ukusukela imali kunye nokubhekisisa amandla amanyathelo aqondileyo ngokuthi akukho uphawu lwesiqephu esetshenziswa. Ngaphandle kwencane, ngoba isolda ingeyintlawo yezinto ezinikezeliyo, kuhlanganisa ukuba angakho umoya womphumeleyo okanye umoya wemibuzo wesintsha kunye nokuhlola kakhulu.
Ngokusho kwesintloko sokuqaleni, izeyisi zokusebenzisa kwevacuum zethuva ndawonye. Iziphiwo ezincane zisetyenziswa ngamandla amaxwebhu kunye neentsha yokuxhasa ukuba bheke izindlela zomthimbu ngemvula wesikhatsi, kunye nokufinyelela kakhulu kule nto yokusebenza. Lokho kuhlela ukuba zonke ijoint ezisoldwe zibe ngqo kunye nokulandelana, ngokubanzi nokulandelana nesiqhina sokuchaza kweendaweni yokusebenza.
Ngokubanzi, ukulayisha esikhakhweni kusetyenziswa ngemibuzo yamandla okuvela eminingi ngeemateriali ezidingeki lokhu phakathi kwemetalu engenayo nokwezimaxwebhu ozisenzelwayo. Ukwenzeka kwesintshabaliso sokunyusa kunye neengenhlamvane lelo msebenzi wamandla kunye neeziqalathisi zokuhlela izigadhi zokugcino eliphephileyo.
Kwiminyaka yasekhombisa, ukuhlanganiswa lwendawo oluhluwe ngokusemthethweni kukusetshenziswa ngokusebenzela amaxhobo angaphandle kwezinto eziphumeleyo noma iiphleti zokuhlola, uteknoloji yokuholwa esikhakhweni yabelana nazo zintlizyo ezincedwayo kunye nemisebenzi ebuhle. Ukuphuma isiqephu sesiholwa esikhakhweni sithola ukuthi akukho umgabheni wesicatshulo noma ukuthi akukho umdlalo wesintsha. Lento lingancamulela ukuba akukho imigomo yenkxaso kunye nokuba yilungu elula lokho lenziwe ngemisebenzi efanelekayo.
Umsebenzi omphumeleyo lwe technology yevacuum reflow ngu kwiindawo zokusetyenziswa kwiindawo zokusebenza, ngoba ukuthi iquality yesolder joint kunomthetho okanye nokuhlola kufanele kuzihlinzelela ukuba amadevise ezilandelayo azisebenzise ngakwesobukhulu. Kungatholakaliyo kakhulu futhi kwiindawo zokusebenza zakwesikhathi, zomedi kalula nezinkozo zemilithari. Ukusetshenziswa kwesivakum reflow kuneene umsebenzi omphumeleyo lokunye ngeprojekti abaningi esizodityengetywa usebenzela imibhalo angaphakathi okanye amathetha ahlala ancedisiweyo yokuba kufanele ukuqinisekiswe nokuthi kube ngendlela efanelekayo nokuthi sishona.
Ukusetshenziswa kwesivakum reflow phambi kokuthi kufanele ukuncedisiwe njengombhalisi wemakhi wesi-vacuum reflow, okungabangako kwiindaweni eziningi ezincedisiweyo. Umsebenzisi uzokusondwa intemperatsha nevacuum ngenxa yamatyala ayiqinisekiseyo akhe eziphumayo kwiispezifikeshoni ze-CVD. Ngokushesha bafakanga amachip ne-circuits asetshenziswa njenge-board enezinye zisolder paste, phambi kokuba babuyele ku-machine.
Grandseed ngumntu omkhulu wokufundiswa kwezinto eziqeshayo, ngenxa yokuba yaziqondiso izinyathelo ezinjalo zezinhlanga lokusebenza. Ukusenzisa kwemisebenzi kunikeza i-96percent. Isimo sokuqala se-Grandseed: uzoba ufikile nokuthi uqinisekile ngendlela elithethwa, uzobe ushale ngaphandle kwezikhathi, zizihlabeleka 24 izandla emizuzwana. Inani lesikhashana kufuneka libe lendlululo kulandelini ne-96%. Kufuneka uvumele ukuba umsebenzi wakho wayehlukile ngokuphelele ukubonisa inani lemfundo. Ngomoya wethu sithi sasenza isikhatsi esidingeni ukuvumela umbhokisi wethu wesikhashana ukuba asibuyele kuwo amagqwaba akhe ahlukileyo kunye nezinduna ezimbili.
Ukuphuntha kwiqhama, ukungapheli okuthile ngokulula, umthetho, kunye nokwezimaxwebhu eziloweni zikhulu ukuyibona izicwangciso ezidinga ezininzi 12 iinyanga zokugcina amandla ngezero, akukho imali ye-36 iinyanga, uphawu lwesizatu seliphawuliwe kuwo lapho akukho imali, uphawu oluhle lwesizatu seliphawuliwe ngu-4 iinyanga, kunye nokusetyenziswa kokubhedelela oluhle yamaxesha eneenkweni yezinto ezithathelwayo kunye nokusetshenziswa kwezinto eziphuthumayo ezinethemba lokusebenza. Isigaba sasendaweni sokusebenza kwalokusebenza lokuhlola lokulandelana lezimali lalayisela ukuhlolwa kwezinhlobo eziningi kunesikhashana, ibheka isenzo sezimali zesikhashana esingezantsi kunesikhashana, kunye nezi-reyipoti zokuhlola kwezimali ezifanekiso kunesikhashana.
Grandseed ngumncedisi weziqhutywa ezinani lokulandelayo. Le ziphrodyekti zethu zizifunyanwe emithathu ne-60 izikhethe kunye nokuba zikhona kwindawo yokugcina olungileyo olungaphantsi kweSaseyophi. Indawo yethe thina icala phambili ukuba ingxenyelwe njengemilando weSaseyophi endaweni yokusebenza yokuhlola lokungcono. Ziphrodyekti zethu zitholakala i-CE kunye ne-ROHS izicwangciso ezithethwe ngu-Europhu.
Grandseed, isikolo somtheleli wesistekhi, uhlangana nokuthengisa, ukusebenza nokugcina. Izinkomo zakhe ezikhulu ziyizinhlobo zokuthenga zesiDIP, imibhalo echaphazekileyo eziPCB, izincinci zokuthengiswa ezintathu, amagama amafune amabini nokuthiwa nokuthengiswa nokuthengiswa nokuthengiswa nokuthengiswa nokuthengiswa nokuthengiswa nokuthengiswa nokuthengiswa nokuthengiswa nokuthengiswa.
