Ukwakhiwa kwe-BOSA:
Ingxenye ekhipha ukukhanya ibizwa nge-TOSA;
Ingxenye eyamukela ukukhanya ibizwa nge-ROSA;
Lapho ababili behlangene, babizwa ngokuthi BOSA.
Ugesi ukuya ku-Optical TOSA:
I-LD (Laser Diode) i-semiconductor laser, esetshenziselwa ukuguqula amasignali kagesi abe amasignali optical ukuze asetshenziswe kumatheminali optical emission
I-Optical to Electric ROSA:
I-PD Photo Dioder photodiode, esetshenziselwa ukuguqula amasignali okukhanya abe okwamanje, abese eguqulwa abe isignali kagesi nge-mutual impedance amplifier (TIA).
I-TOSA ne-ROSA ingasetshenziswa ngokuhlukana njenge-LC optical module kanye ne-SC optical module. Uma i-BOSA isetshenziswa, imvamisa isetshenziswa njenge-SC optical module
Ukukhethwa kosayizi kusekelwe kusayizi wangempela wamanje futhi kunolwazi olulandelayo:
Imbobo engu-10mil ene-PAD engu-20mil ihambisana ne-current engu-0.5A yentambo engu-20mil, kanti imbobo engu-40mil ene-PAD engu-40mil ihambisana ne-current ye-1A yentambo engu-40mil. Lapho isidingo samanje siphezulu, ama-vias amaningi angabekwa ezindaweni eziseduze ukuze kwandiswe umthamo wokuthwala. Izindleko zokumba ngokuvamile zibalelwa ku-30% kuya ku-40% wezindleko zokukhiqiza ze-PCB.
Uma ucabangela kokubili izindleko kanye nekhwalithi yesignali, kungcono ukukhetha i-10/20mil (i-drilling/soldering pad) yamabhodi angu-6-10. Kuma-PCB anobukhulu obukhulu kanye namancane, ukubhola okungu-8mil kungazanywa. Usayizi omncane wokumba wenza kube nzima ukufeza inqubo, i-drill bit kulula ukuphuka, futhi izindleko ziyanda. Ngokuvamile, izimboni zamabhodi zidinga ukuthi kukhokhiswe imali yokumba ngokumba ngaphansi kuka-11.81mil.
Ngokombono wokuklama, imbobo edlulayo ihlanganisa imbobo yokumba emaphakathi kanye nephedi ye-solder ezungezile, enquma usayizi wembobo yokubhoboza. Njengoba ubukhulu bembobo edlulayo buncane, amandla e-parasitic mancane, asiza kakhulu ekuzinzeni kwamasignali esivinini esikhulu.
Ngesikhathi esifanayo, ubukhulu bomgodi wokubhoboza bunqunyelwe inqubo yokumba kanye nenqubo ye-electroplating; Imbobo encane, kuthatha isikhathi eside, futhi kulula ukuchezuka endaweni ephakathi. Uma ukujula kokumba (ngokujula kwembobo okungaba ngu-50mil) kudlula izikhathi eziyisi-6 endaweni yokumboza, akunakwenzeka ukuqinisekisa ukucwecwa kwethusi okufanayo odongeni lwembobo. Ngakho-ke, ubuncane be-diameter bokubhola abangahlinzekwa ngabakhiqizi be-PCB ngu-8mil.
Okungenhla ukubuka okufushane kokuthi "Isingeniso Kumapharamitha Abalulekile we-BOSA - ngosayizi (I)", okungasebenza njengereferensi yawo wonke umuntu. Inkampani yethu ineqembu eliqinile lezobuchwepheshe futhi ingahlinzeka ngezinsizakalo zobuchwepheshe kumakhasimende. Njengamanje, inkampani yethu inemikhiqizo ehlukahlukene: ehlakaniphilewena, imojuli ye-optical yokuxhumana, i-optical fibre module, i-sfp optical module,oltimishini, Ethernetshintshanezinye izinto zenethiwekhi. Uma udinga, ungafunda okwengeziwe ngabo.
