Thaum ntim cov diode laser, xaiv qhov tsim nyog cam preform rau txheej txheem tuag-ua ke yog qhov tseem ceeb thawj kauj ruam rau kev ntseeg tau ntev lub sijhawm, txij li cov sib koom tes ua lub hauv paus ua lub hauv paus ua haujlwm thermal conductor rau cua sov dissipation. Raws li ib tug tshwm sim, cov mos mos solders xws li InSn yog feem ntau nyiam vim hais tias cov flexibly ntawm cov tshuaj lo yuav pab tau mitigate txoj kev nyuaj siab tshwm sim los ntawm lub mismatch ntawm coefficient ntawm thermal expansion (CTE) ntawm cov nti thiab lub submount. Ib qho txiaj ntsig ntxiv ntawm kev siv InSn solder yog qhov qis tsis ntab (157oC) uas txo cov thermal load ntawm lub diode thaum lub sijhawm sib koom ua ke. Thaum muag cov khoom lag luam tuaj yeem cuam tshuam los ntawm ntau dua cov thermal-nkees thiab nkag siab dua li cov muag khoom nyuaj xws li AuSn, qhov kev pheej hmoo ntawm cov kab nrib pleb hauv qhov tuag lossis cuam tshuam ntawm kev tuag thaum lub sijhawm thermal cycling vim tias CTE mismatch feem ntau tawm-txoj kev muaj txiaj ntsig ntawm AuSn.
Tom qab kev tuag-daim ntawv cog lus, cov kauj ruam tseem ceeb tshaj plaws nyob rau hauv cov txheej txheem ntim cov diode yog cov xaim txuas Nyob rau hauv txoj kev no, cov xaim nyias nyias txuas nrog sab qaum ntawm qhov tuag thiab qhov xa tawm kom tso tawm tam sim no kom dhau ntawm qhov diode. Rau cov tsoos hluav taws xob tam sim no xaim sib txuas sib xyaw alloyed hom electrodes raug siv, tab sis thaum siv ntawm laser diodes lawv nyiam ntxias cov teeb meem loj hauv cov qauv diode vim yog hlau diffusion rau hauv diode. Yog li ntawd, ua kom cov hauv lub neej ntawm ib tug laser diode, koj yog zoo npaum li cas tawm siv khiav ib tug ntau dua tus naj npawb ntawm cov tseem kub hlau bonds uas muaj peev xwm nqa tib tam sim no load tab sis muaj ntau sib xws nrog lub tuag ho kom txhob muaj cov yuav qhov muaj tseeb ntawm cov hlau diffusion. Yog hais tias muaj yog tsis muaj lwm yam xaiv dua mus siv hlau electrodes, ces nws yog ib qhov zoo tshaj plaws los mus siv Schottky-hom electrodes uas muaj kub thiab yog li ntawd, yuav ua rau tsawg dua tej tsis xws luag dua tsoos alloys.
