Kupanga kwa BOSA:
Mbali yotulutsa kuwala imatchedwa TOSA;
Gawo lolandira kuwala limatchedwa ROSA;
Awiri akabwera palimodzi, amatchedwa BOSA.
Magetsi kupita ku Optical TOSA:
LD (Laser Diode) semiconductor laser, yomwe imagwiritsidwa ntchito kutembenuza ma siginecha amagetsi kukhala ma siginecha owoneka kuti agwiritsidwe ntchito m'malo opangira magetsi.
Optical to Electric ROSA:
PD Photo Dioder photodiode, yomwe imagwiritsidwa ntchito potembenuza ma siginecha owunikira kukhala apano, omwe amasinthidwa kukhala siginecha yamagetsi kudzera pamutual impedance amplifier (TIA).
TOSA ndi ROSA zitha kugwiritsidwa ntchito padera ngati LC Optical module ndi SC Optical module. BOSA ikagwiritsidwa ntchito, imagwiritsidwa ntchito ngati SC Optical module
Kusankhidwa kwa kukula kumatengera kukula komwe kulipo ndipo kumakhala ndi izi:
Bowo la 10mil lomwe lili ndi PAD 20mil limafanana ndi 0.5A pa waya wa 20mil, ndipo dzenje la 40mil lokhala ndi 40mil PAD limagwirizana ndi 1A pa waya wa 40mil. Pamene kufunika panopa ndi mkulu, vias angapo akhoza kuikidwa malo moyandikana kuonjezera kubala mphamvu. Mtengo wobowola nthawi zambiri umatengera 30% mpaka 40% ya mtengo wopangira PCB.
Poganizira za mtengo ndi khalidwe la chizindikiro, ndi bwino kusankha 10/20mil (bowola / soldering pad) kwa matabwa 6-10 osanjikiza. Kwa ma PCB olemera kwambiri komanso ang'onoang'ono, kubowola kwa 8mil kungayesedwe. Kukumba kwakung'ono kumapangitsa kuti zikhale zovuta kukwaniritsa ntchitoyi, kubowola kumakhala kosavuta kuthyoka, ndipo mtengo wake ukuwonjezeka. Nthawi zambiri, mafakitole a board amafuna kuti azilipiridwa pobowola zosakwana 11.81mil.
Kuchokera pamawonekedwe apangidwe, dzenje lapakati limaphatikizapo dzenje lobowola pakati ndi zozungulira zozungulira solder, zomwe zimatsimikizira kukula kwa dzenje lobowola. Monga kukula kwa dzenje laling'ono, mphamvu ya parasitic ndi yaying'ono, yomwe imathandizira kukhazikika kwa zizindikiro zothamanga kwambiri.
Panthawi imodzimodziyo, kukula kwa dzenje kumachepetsedwa ndi njira yobowola ndi electroplating; Bowo laling'ono, limatenga nthawi yayitali, ndipo zimakhala zosavuta kuti apatukane ndi malo apakati. Pamene kubowola kuya (kupyolera mu dzenje kuya pafupifupi 50mil) kupitirira nthawi 6 pobowola, n'zosatheka kuonetsetsa kuti yunifolomu plating mkuwa pa khoma dzenje. Choncho, pobowola awiri awiri kuti opanga PCB angapereke ndi 8mil.
Zomwe zili pamwambazi ndizofotokozera mwachidule za "Introduction to Key Parameters of BOSA - kudzera mu kukula (I)", zomwe zingakhale ngati zofotokozera kwa aliyense. Kampani yathu ili ndi gulu lolimba laukadaulo ndipo imatha kupereka chithandizo chaukadaulo kwa makasitomala. Pakadali pano, kampani yathu ili ndi mitundu yosiyanasiyana: yanzeruinu, gawo lolumikizana la kuwala, gawo la kuwala kwa fiber, sfp optical module,oltzida, Efanetikusinthandi zida zina zamaneti. Ngati mukufuna, mutha kuphunzira zambiri za iwo.
