3. Bond bond da Hawaye: A wuri na biyu, da tsinke sake sauka, samar da a na biyu amfani da ka'idodi guda na karfi da Ultrasonic makamashi. Kai tsaye bayan wannan na biyu an kafa shi, a kilamfi yana riƙe da waya a wurin yayin da kayan aiki yana motsawa sama, hatsarin waya a diddigin takardar alƙawari. Wannan ya bar bawa Shirya don fara na gaba waya takardar alƙawari sake zagayowar. Wannan duka Tsarin haɗin waya don guda ɗaya takardar alƙawari yana faruwa a milliseckonds.

Me yasa bawan waya waya yake da mahimmanci ga mai kyau?

Da Bonding waya ba wai kawai shugaba bane; kayan haɗin injiniya ne mai mahimmanci waɗanda kaddarorinsu ke tasiri kan inganci da abin dogaro na takardar alƙawari. Mafi gama abu tsinke bawa ne goron ruwa waya, sau da yawa riged tare da karamin adadin silicon (1% si) don ba shi ƙarfi da wuya da takardar alƙawari halaye. Taimakon al m waya yana da kyau saboda yana samar da karfi da aminci ultrasonic walda a \ da zazzabi daki. Hakanan yana da ƙarancin yiwuwa don ƙirƙirar mahaɗan tsinkaye lokacin da aka danganta shi goron ruwa pads a kan sassaƙe, babban dogon lokaci abin dogaro damuwa.

Jan ƙarfe waya Hakanan yana samun shahararrun mutane tsinke bawa Saboda mafifita na lantarki da rashin ƙarfi yin aiki. Koyaya, jan ƙarfe yana da wahala fiye da goron ruwa kuma yana buƙatar daban takardar alƙawari sigogi da kuma wani lokacin an sarrafa shi, inert halin zaman jama'a don hana hadewa A lokacin takardar alƙawari tsari. Zabi tsakanin Taimakon al m da Chu ya dogara da bukatun aikin aikace-aikacen game da hadadden hadadden a cikin masana'antu tsari. Da waya dole ne ya kasance da daidaito diamita da kayan dukiya Don tabbatar da maimaitawa takardar alƙawari.

Mene ne mahimmancin aiki na kayan aiki a cikin wannan tsari?

Da tsinke kanta shine zuciyar Ubangiji tsinke takardar alƙawari tsari. Yana da kayan aiki wannan yana watsa karfi da Ultrasonic makamashi daga bawa ga waya. Ingancin wannan karamin, daidaitaccen injiniyan kayan wucin gadi yana da ma'ana don cimma mai kyau takardar alƙawari. A talauci sanya tsinke na iya haifar da babban matsaloli, daga saba takardar alƙawari samarwa don lalata m Bond Pad a kan sassaƙe.

A Dongxin, muna kwarewa a masana'antun wadannan mahimman kayan aiki. Mai inganci tsinke Dole ne ya kasance:

• Madaidaitan mutane: Sifar da tsinke Tip, gami da girma, kusurwa, da rami don waya, dole ne cikakke ga yadda yakamata ƙazanta da waya kuma samar da karfi takardar alƙawari.
• Mafi girma abu: Yawanci ana yin su ne daga Cargten Carbide don tsananin ƙarfi da kuma sanya juriya, tabbatar da rayuwa mai tsawo takardar alƙawari tsari.
• M farfajiya: The farfajiya na tsinke cewa lambobin waya Dole ne ya zama mai dacewa mai santsi don hana m kuma tabbatar da tsabta takardar alƙawari da hawaye.

Injiniya kamar Marcus ya san cewa jimlar ikon mallakar don a tsinke ba farashin siyan sa bane, amma abin dogaro kuma samar da shi yana ba da damar. Mai inganci tsinke shine karamin hannun jari wanda ke kare mafi girma. Wannan shine dalilin da yasa al'ada wedding kayan aiki galibi ana buƙatar musamman don aikace-aikace na musamman.

Ta yaya sarrafa zazzabi zai shafi ingancin haɗin waya?

Ƙarfin zafi mai mahimmanci ne misali a waya bawa, da adadin zafi amfani da ma'anar nau'in bawa.

1. Ultrasonic Bonding: Wannan kyakkyawar amfani ce ta tsinke takardar alƙawari. Wannan m za a iya yi a zazzabi daki, amfani kawai na inji karfi da babban-mita ɓata. Wannan ya dace da na'urorin da ake kulawa da yawan zafin jiki inda amfani zafi na iya lalata kayan.
2. Haɗin kai: Wannan tsohuwar m Reces On zafi (Yawanci 150 ° C - 350 ° C) da ƙarfi shi kaɗai don ƙirƙirar takardar alƙawari ta hanyar m-jihar yaduwa. Ba amfani Ultrasonic makamashi.
3. Bonderonic Bonding: Wannan hanyar da aka fi amfani da ita ƙwallo bawa. Ya haɗu da duk abubuwan guda uku: zafi, karfi, da Ultrasonic makamashi. Kara rashin ƙarfi Makamashi mai laushi da kayan, bada izinin sauri kuma mafi ƙarfin hali takardar alƙawari A ƙananan ƙarfi da matakan iko.

Don \ domin tsinke bawa, samun ikon takardar alƙawari babu zafi yana ba da cikakkiyar sassauƙa. Koyaya, ga wasu kayan kamar jan ƙarfe waya, ƙara adadin matsakaici na zafi na iya inganta takardar alƙawari inganci. Na daidai ƙarfin zafi kula da saboda haka wani babban al'amari na inganta waya takardar alƙawari don kowane aikace-aikacen da aka bayar.

Wadanne aikace-aikace ne mai haɗarin da aka fi son dabarar da aka fi so?

Lokacin da ƙwallo bawa wani ma'aikaci ne mai son kai, akwai wuraren da yawa masu yawa inda halaye na musamman na tsinke takardar alƙawari Sanya shi mafifita, ko ma kawai, zabi. Tsaki Bonding ya fi so A cikin waɗannan yanayin:

• RF da na'urorin microwave: A babban mita, siffar da tsawon waya na iya yin aiki a matsayin hadarin, yana shafar aikin da'ira. Low, lebur madauki da madaidaici masu daraja na a tsinke takardar alƙawari sun fi mai sarrafawa sosai kuma ana iya faɗi, yana da mahimmanci don Rf Acs.
• Kayan Wutar Lantarki: Na'urorin kamar Igbts da Mosfets suna ɗaukar manyan kudade kuma dole ne su disse zafi. Nauyi-diamita goron ruwa tsinke takardar alƙawari yana ba da kyakkyawan aiki na yanzu da abin dogaro a \ da Tsarin zafi, inda zinari ƙwallo takardar alƙawari zai iya zama da labiri.
• Docarfin babban aikace-aikacen: Kamar yadda kwakwalwan kwakwalwan kwamfuta suka zama cike da densely packed, sarari tsakanin takardar alƙawari pads yana raguwa. Ba kamar Ball Bonding ba, inda zagaye ƙwallo Yana bayyana mafi karancin karami (fili), kunkuntar, a-line dutsen da tsinke takardar alƙawari yana ba da damar yin lamba mai yawa.
• Yawan zafin jiki-mai mahimmanci: Don na'urori masu kyau ko kayan aikin da ba za su iya jure wa zafi da ake buƙata don hermosonic ƙwallo takardar alƙawari, ikon yin babban-ingancin ultrasonic tsinke takardar alƙawari a \ da zazzabi daki wata fa'ida ce mai mahimmanci. Da tsinke takardar alƙawari shima ya zama ruwan dare gama gari Injula na Igbt.

Menene mahimman sigogi don sarrafawa don cikakken haɗin?

Cimma maimaitawa, yawan amfanin ƙasa tsinke takardar alƙawari na bukatar madaidaici kula da Sama da mabuɗin bawa sigogi. Wadannan sigogi guda hudu suna samar da "girke-girke" don mai kyau takardar alƙawari:

1. Ƙarfi: Yawan karfin matsa amfani da tsinke ga waya. Karancin karfi da sakamako a cikin rauni takardar alƙawari; da yawa zai iya lalata Bond Pad ko kuma na mutu a ƙasa.
2. Ƙarfin Ultrasonic: Tsanani na ultrasonic goge aiki. Ana buƙatar wannan makamashi don karya hanci fari yadudduka da ƙirƙirar walda, amma ƙarfi mai yawa na iya haifar da takardar alƙawari ya zama mai kauri da rauni.
3. Lokaci: Tsawon lokacin da aka yi amfani da ƙarfin ikon ultrasonic. Wannan yana buƙatar kasancewa da tsawo don samar da cikakken takardar alƙawari amma gajere isa ya kara fitowar fitarwa.
4. Ƙarfin zafi: Yayinda ake yin sau da yawa a zazzabi daki, saboda wasu aikace-aikace, gab da substrate ƙarfin zafi na iya rage sauran sigogi da ake buƙata da inganta takardar alƙawari.

Neman ingantaccen tsari taga don waɗannan sigogi suna da babban aiki don a waya bawa m. Yana buƙatar gwaji da zurfin fahimta game da kayan da kayan aiki, kamar mu Mai kauri mai kauri a hankali.

Shin wedged hadari ya kasa kuma menene abubuwan da ke haifar?

Ee, kamar kowane masana'antu tsari, a tsinke takardar alƙawari iya kasawa. Fahimtar hanyoyin da aka samu yana da mahimmanci don matsala da ci gaba. Kasancewa gama gari sun hada da:

• Bond: The takardar alƙawari Cikakke kota daga Bond Pad. Wannan galibi ana haifar dashi ta hanyar ƙazanta a kan farfajiya ko ba daidai ba takardar alƙawari sigogi (misali, kasa da isasshen ikon ultrasonic ko karfi).
• Diddige: Crack siffofin a cikin waya a "diddige" na takardar alƙawari, inda waya ya fice da takardar alƙawari. Wannan magana ce mai danniya kuma ana iya haifar da shi ta hanyar kaifi tsinke kayan aiki ko wuce kima na inji Rashin daidaituwa yayin takardar alƙawari.
• Lalacewar Pad: Karfi da ultrasonic makamashi crack ko crater da Bond Pad ko kuma silicon yadudduka ƙarƙashinsa. Wannan lalacewa ce mai wahala sau da yawa ana haifar dashi ta hanyar wuce kima bawa karfi.
• Haɗin gwiwa: Girma da siffar takardar alƙawari bambanta daga daya takardar alƙawari zuwa na gaba. Wannan na iya zama saboda sawa tsinke, saba waya inganci, ko matsala tare da bawa kanta.

Hana wadannan kasawa na bukatar tsari tsari kula da, ingantattun abubuwa masu inganci kamar tsinke da waya, da kuma kula da yau da kullun na bawa kayan aiki. Da ƙarfi na takardar alƙawari shine babban burin.

Ta yaya injiniyoyin tallafi na Dongxin a cikin Master Pedan Haɗin Seji?

Mastering The tsinke takardar alƙawari Tafiya ce ta ci gaba, kuma mun ga kanmu a matsayin abokan tarayya a wannan tafiya. Don m Kamar Marcus, Tallafi daga mai siye ya wuce nesa da jigilar kayayyaki kawai. Muna ba da ƙwarewar fasaha don taimakawa warware matsala bawa kalubale.

Bayananmu sun hada da:
