Thawj kauj ruam nyob rau hauv tus txheej txheem ntawm kev txais ib nti tej zaum yuav lub thaj;ib qho TO suav nrog ib thaj chaw uas ua kom sov rau lub qhov (socket) TO, ib lub nti uas LDs rau lub dab dej kub, thiab lub teeb rov qab PD;
Cov txheej txheem mounting tshwj xeeb yuav txawv heev: cov khoom uas yuav tsum tau txuas yog feem ntau yog LD / PD nti, los yog TIA, resistor / capacitor;qhov kev tso kawm tuaj yeem ua rau ntawm txhuas nitride cua sov dab dej lossis ncaj qha rau ntawm PCB;Kev tso kawm Eutectic welding lossis conductive nplaum tuaj yeem siv tau;lub thaj tsuas tuaj yeem xav tau kaum lossis ntau pua microns ntawm qhov raug, xws li TIA, resistors, thiab sub-micron raug, xws li passive flip-chip vuam.
Tom qab hais tag nrho cov no, qhov tseeb yog dab tsi?Yeej tsis zoo li yuav muaj kev txhais lus.Txawm li cas los xij, nws tuaj yeem pom los ntawm cov piv txwv saum toj no uas lawv muaj ib qho zoo sib xws: cov cuab yeej siv los tso thiab kho qhov chaw tso rau ntawm tus cab kuj nrog qhov tseeb kom ua tiav ib qho haujlwm tshwj xeeb.(Vim li cas siv cov cuab yeej siv? carrier, tsau txoj kev, raug.Thiab cov neeg nqa khoom siv dab tsi, cov khoom siv twg yog xaiv, thiab qhov yuav tsum tau muaj qhov tseeb yog dab tsi, nws nyob ntawm qhov ua haujlwm ntawm qhov khoom yuav tsum tau ua tiav.
Nov yog saib ntawm ntau yam muaj peev xwm muaj nyob rau hauv plaub lub ntsiab lus ntawm thaj:
Feem ntau ntawm cov mounts yog LD thiab PD chips.
TIA / Tsav Tsheb / Resistor / Capacitors, xws li cov chaw tso chaw uas tsis tas yuav tsum muaj qhov tseeb, tuaj yeem hloov tau manually es tsis txhob ntim loj.
Cov neeg nqa khoom tshaj plaws yog AIN lub dab dej kub;Nrog rau kev txhim kho ntawm cov chips sib xyaw, PLC chips thiab silicon optical chips kuj tau dhau los ua lub cev sib txuas, xws li silicon teeb grating coupling chips, uas yuav tsum tau LaMP rau mounted ntawm silicon optical chips;PCB yog cov neeg nqa khoom muaj nyob hauv cov pob COB, xws li cov ntaub ntawv sib txuas lus 100G-SR4 modules, PD / VSCEL tau ncaj qha rau ntawm PCB.
Au80Sn20 alloy yog ib hom LD-mount eutectic solder.Conductive nplaum feem ntau yog siv los mount PD.UV kua nplaum taag lens yog tsim nyog.
Qhov tseeb nyob ntawm daim ntawv thov tshwj xeeb;
Qhov twg yuav tsum tau optical txoj kev coupling, qhov tseeb yuav tsum tau kuj siab.
Passive alignment yuav tsum muaj qhov tseeb siab dua li kev sib txuas ua ke.
Qhov kev tso kawm LD xav tau qhov tseeb dua li qhov kev tso kawm PD,
TIA / resistor / capacitor tsis xav tau qhov tseeb, tsuas yog lo nws.
Txoj kev tso chaw dav dav
Kub-tin eutectic solder thaj
Conductive paste thaj
Qhov twg qhov tseeb tsis siab, koj tsuas yog yuav tsum tau saib ntawm CCD txhawm rau ntes cov duab ntawm cov nti thiab cov substrate tib lub sijhawm, thiab siv cov cim sib dhos lossis cov npoo nti los ua kom zoo.
Rau daim ntawv thov flip-chip, ntau CCDs kuj yuav tsum tau, saib ob qho tib si hauv qab ntawm lub nti thiab qhov chaw ntawm lub substrate.High-precision daim ntaub ntawv kuj yuav tsum tau tshwj xeeb alignment marks.
