Solder Materials for Laser Diode Bars: Mahimman Gada Tsakanin Ayyuka da Dogara

A cikin ƙira da masana'anta na laser semiconductor masu ƙarfi, sandunan diode laser suna aiki azaman ginshiƙan raka'a masu fitar da haske. Ayyukansu ba wai kawai ingancin ingantattun kwakwalwan Laser ba amma har ma akan tsarin marufi. Daga cikin nau'o'i daban-daban da ke cikin marufi, kayan solder suna taka muhimmiyar rawa a matsayin yanayin zafi da wutar lantarki tsakanin guntu da ma'aunin zafi.

1. Matsayin Solder a Laser Diode Bars

Sandunan diode na Laser yawanci suna haɗa abubuwan fitarwa da yawa, yana haifar da yawan ƙarfin ƙarfi da tsauraran buƙatun sarrafa zafi. Don cimma ingantacciyar watsawar zafi da kwanciyar hankali, kayan solder dole ne su cika ka'idodi masu zuwa:

① High thermal conductivity:

Yana tabbatar da ingantaccen canja wurin zafi daga guntu na Laser.

② Kyakkyawan ruwa mai kyau:

Yana ba da haɗin kai mai tsauri tsakanin guntu da ƙasa.

③ Madaidaicin wurin narkewa:

Yana hana sake kwarara ko lalacewa yayin sarrafawa ko aiki na gaba.

④ Madaidaicin ƙimar haɓakar thermal (CTE):

Yana rage danniya mai zafi akan guntu.

⑤ Kyakkyawan juriya ga gajiya:

Yana tsawaita rayuwar sabis na na'urar.

2. Nau'in Solder gama gari don Marufi Bar Laser

Wadannan su ne manyan nau'ikan kayan solder guda uku da aka saba amfani da su a cikin marufi na sandunan diode na Laser:

①Gwal-Tin Alloy (AuSn)

Kaddarori:

Eutectic abun da ke ciki na 80Au/20Sn tare da wurin narkewa na 280°C; high thermal watsin da kuma inji ƙarfi.

Amfani:

Kyakkyawan kwanciyar hankali mai zafi, tsawon rayuwar gajiya mai zafi, ba tare da gurɓatawar kwayoyin halitta ba, babban abin dogaro

Aikace-aikace:

Sojoji, sararin samaniya, da kuma babban tsarin Laser masana'antu.

②Indium mai tsafta (A)

Kaddarori:

Matsayin narkewa na 157 ° C; taushi kuma mai saurin lalacewa.

Amfani:

Babban aikin hawan keke na thermal, ƙarancin danniya akan guntu, manufa don kare sifofi masu rauni, dacewa da buƙatun haɗin kai mai ƙarancin zafi

Iyakoki:

Mai yiwuwa ga oxidation; yana buƙatar inert yanayi yayin aiki, ƙananan ƙarfin injiniya; bai dace da aikace-aikace masu girma ba

③Haɗin Solder Systems (misali, AuSn + In)

Tsarin:

Yawanci, AuSn ana amfani da shi a ƙarƙashin guntu don ƙaƙƙarfan haɗe-haɗe, yayin da In kuma ake amfani da shi a saman don ingantaccen buffering thermal.

Amfani:

Haɗa babban abin dogaro tare da taimako na danniya, yana haɓaka ƙarfin marufi gabaɗaya, ya dace da yanayin aiki iri-iri

3. Tasirin ingancin Solder akan Ayyukan Na'ura

Zaɓin zaɓin kayan solder da sarrafa tsari yana tasiri sosai ga aikin lantarki-na gani da kwanciyar hankali na na'urorin Laser na dogon lokaci:

Karkashin ci gaba da aiki mai ƙarfi, ko da ƙananan lahani a cikin saida na iya haifar da haɓakar zafi, yana haifar da lalacewa ko gazawar na'urar. Saboda haka, zabar high quality-solder da aiwatar da daidai soldering matakai ne muhimmi ga cimma high-aminci Laser marufi.

4. Yanayin Gaba da Ci gaba

Kamar yadda fasahar Laser ke ci gaba da shiga cikin sarrafa masana'antu, aikin tiyata na likita, LiDAR, da sauran fannoni, kayan solder don fakitin Laser suna ci gaba a cikin waɗannan kwatance:

①Siyar da ƙarancin zafin jiki:

Don haɗin kai tare da kayan zafi mai zafi

②Mai siyarwa mara gubar:

Don saduwa da RoHS da sauran ƙa'idodin muhalli

③Maɗaukakiyar Ƙaƙwalwar Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararru (TIM):

Don ƙara rage juriya na thermal

④Fasahar siyar da ƙananan yara:

Don tallafawa miniaturization da babban haɗin kai

5. Kammalawa

Ko da yake ƙananan ƙararrawa, kayan solder sune masu haɗin kai masu mahimmanci waɗanda ke tabbatar da aiki da amincin na'urorin laser masu ƙarfi. A cikin marufi na Laser diode sanduna, zabar dama solder da inganta bonding tsari ne da muhimmanci ga cimma dogon lokacin da barga aiki.

6. Game da Mu

Lumispot ya himmatu wajen samar wa abokan ciniki ƙwararru kuma abin dogaro da kayan aikin Laser da mafita na marufi. Tare da ƙwarewa mai yawa a cikin zaɓin kayan siyar, ƙirar sarrafa zafin jiki, da ƙimar dogaro, mun yi imanin cewa kowane gyare-gyare daki-daki yana ba da hanya zuwa ga inganci. Don ƙarin bayani kan fasahar marufi na Laser mai ƙarfi, jin daɗin tuntuɓar mu.
