1. Yintoni iphakheji ethambileyo yeCOB
Abasebenzisi be-intanethi abanononophelo banokufumanisa ukuba kukho into emnyama kwezinye iibhodi zesekethe, yintoni le nto?Kutheni ikwibhodi yesekethe?Uyintoni umphumo?Enyanisweni, olu luhlobo lwephakheji.Sihlala siyibiza ngokuba "iphakheji ethambileyo".Kuthiwa ipakethe ethambileyo eneneni "inzima", kwaye izinto zayo ziyi-epoxy resin., Ngokuqhelekileyo sibona ukuba indawo yokufumana intloko efunyenweyo nayo yile nto, kwaye i-chip IC ingaphakathi kuyo.Le nkqubo ibizwa ngokuba "yi-bonding", kwaye ngokuqhelekileyo siyibiza ngokuthi "ukubopha".
Le yinkqubo yokudibanisa ucingo kwinkqubo yokuvelisa i-chip.Igama layo lesiNgesi yiCOB (Chip On Board), oko kukuthi, i-chip kwi-packaging board.Le yenye yetekhnoloji yokufakwa kwetshiphu engenanto.I-chip ifakwe kwi-epoxy resin.Ifakwe kwibhodi yesekethe eprintiweyo yePCB, kutheni ke ezinye iibhodi zesekethe zingenalo olu hlobo lwephakheji, kwaye zithini iimpawu zolu hlobo lwephakheji?
2. Iimpawu zephakheji ethambileyo ye-COB
Olu hlobo lwetekhnoloji yokupakisha ethambileyo idla ngokuba yindleko.Njengoko ukufakwa kwe-chip elula kakhulu, ukwenzela ukukhusela i-IC yangaphakathi emonakalweni, olu hlobo lokupakisha ngokubanzi lufuna ukubunjwa kwexesha elilodwa, elibekwe ngokubanzi kumphezulu wobhedu webhodi yesekethe.Ingqukuva kwaye umbala umnyama.Le teknoloji yokupakisha ineenzuzo zeendleko eziphantsi, ukonga indawo, ukukhanya kunye nokuncinci, isiphumo esihle sokutshatyalaliswa kobushushu, kunye nendlela yokupakisha elula.Iisekethe ezininzi ezidibeneyo, ngokukodwa iisekethe eziphantsi kwexabiso eliphantsi, zifuna ukudibanisa kuphela kule ndlela.I-chip yesekethe iholwa ngaphandle ngeengcingo zetsimbi ezininzi, kwaye emva koko inikezelwe kumenzi ukuba abeke i-chip kwibhodi yesekethe, ithengise ngomatshini, kwaye emva koko isebenzise iglu ukuze iqiniswe kwaye iqine.
3. Izihlandlo zokufaka izicelo
Ngenxa yokuba olu hlobo lwepakethe luneempawu zalo ezikhethekileyo, lukwasetyenziswa kwezinye iisekethe zesekethe zombane, ezinje ngabadlali beMP3, amalungu ombane, iikhamera zedijithali, iikhonsoli zomdlalo, njl.njl., ekusukeleni iisekethe ezixabisa kancinci.
Ngapha koko, ukupakishwa okuthambileyo kwe-COB akupheleli kwiitshiphusi kuphela, kukwasetyenziswa ngokubanzi kwii-LED, ezinje ngomthombo wokukhanya we-COB, obubuchwephesha obudityanisiweyo bomthombo wokukhanya obudityaniswe ngokuthe ngqo kwisibuko sesinyithi esisezantsi kwi-chip ye-LED.
