Nke a abụrụla teknụzụ bụ isi maka idozi ntụpọ nke ịgbado ọkụ ọdịnala.

Isi Ngwa ndapụta nke Ultrasonic Soldering Irons na Vacuum Glass Processing

N'ime usoro nhazi nke oghere oghere, usoro ịgbado ọkụ na-elekwasị anya na usoro atọ dị mkpa: tupu - mkpuchi nke oyi akwa metallization, akara ihu, na ndozi kọlụm nkwado. Ultrasonic soldering ígwè, na ha kọmpat Ọdịdị na kpomkwem controllable okpomọkụ na vibration parameters, nwere ike flexibly imeghari ma akwụkwọ ntuziaka ọrụ na akpaghị aka mmepụta ahịrị, na-egwu ihe irreplaceable ọrụ na nke ọ bụla ogbo.

(I) Tupu - mkpuchi nke ihe na-ere ihe maka iko metallisation Layer

Enweghị ike ijikọ elu nke enyo agụụ na-enweghị ntụkwasị obi na igwe na-ere. A ga-ebu ụzọ kpuchie oyi akwa metallization (dịka Ag metal tapawa, Cu - Ag alloy paste, wdg) na ebe a ga-agbado (na-abụkarị akụkụ anọ). Solder tupu - mkpuchi mkpuchi bụ ihe dị mkpa iji hụ na mma akara na-esote. Usoro mkpuchi mkpuchi ọdịnala na-enwekarị nsogbu dị ka nha nha nha na-adịghị mma yana njikọ na-adịghị ike na oyi akwa metallization, na-eduga na welds ezughị ezu ma ọ bụ na-efunahụ welds n'oge akara na-esote.

Ultrasonic soldering ígwè nwere ike kpomkwem napụta solder waya site a waya nri ngwaọrụ, na, na njikọ na ihe adsorption ngagharị n'elu ikpo okwu idozi iko mkpụrụ, ụgbọala na soldering ígwè n'ọnụ ịkwaga evenly site a atọ- akụkụ ngagharị akụrụngwa, nweta kpọmkwem tupu - mkpuchi nke solder. N'oge tupu - mkpuchi usoro, okpomọkụ nwere ike ịchịkwa n'etiti 150 ℃ na 400 ℃, na solder oyi akwa ọkpụrụkpụ nwere ike kpomkwem na-achịkwa n'etiti 0.1mm na 3mm, izute chọrọ maka obosara na ọkpụrụkpụ nke agụụ iko onu akara akara. Ọkụ dị elu - ugboro ugboro na-eme ka o doo anya na ihe na-ere ahịa na oyi akwa metallization ejikọtala nke ọma, na-akpụ akwa akwa tupu - welded oyi akwa. Akara na-esote na-achọ ikpo ọkụ iji gbazee oyi akwa nke welded, na-eme ngwa ngwa n'usoro mkpuchi kwụsiri ike ma na-ebelata ọnụ ahịa nsị. N'ime ọnọdụ ngwa a, enwere ike ịchịkwa okpomọkụ nke ọkọlọtọ na mmepụta oscillation nke ultrasonic soldering iron site na netwọk mpaghara, na-eme ka nkwụsi ike na nkwụsi ike nke tupu - mkpuchi.

(II) Vacuum Glass Edge Sealing Welding

Ede akara bụ usoro kachasị mkpa na nhazi iko oghere. Ogo njichi ya na-ekpebi ozugbo ike oyi akwa oghere iji nọgide na-enwe agụụ, si otú a na-emetụta ihe mkpuchi ọkụ nke ngwaahịa, ịrụ ọrụ mkpuchi ụda, yana ndụ ọrụ. Akara n'ọnụ ọdịnala na-ejikarị obere - agbaze - akara uzuzu ntụ ntụ ma ọ bụ brazing nkịtị. Nke mbụ na-adịkarị mfe ịchichi akwa oyi akwa, ebe nke ikpeazụ chọrọ mgbanwe, na-eduga na mmetọ oyi akwa, na nkwonkwo solder na-adịkarị mfe ikuku ikuku, na-emezughị ogologo oge chọrọ ikuku ikuku.

Ultrasonic soldering ígwè nwere ike nweta fluxless brazing akàrà na nsọtụ nke agụụ iko, karịsịa adabara ịgbado ọkụ na ala - okpomọkụ metal solder. N'oge ịgbado ọkụ, ndị soldering ígwè n'ọnụ na-akpali na a mgbe nile ọsọ n'akụkụ iko, na a wụrụ awụ solder, n'okpuru ịma jijiji, evenly ekpuchi metallized oyi akwa, na-akpụ a na-aga n'ihu na ok akara weld. Ike ịma jijiji na-ewepụ ikuku ikuku n'ime ihe na-ere ahịa, na-egbochi oghere na oyi akwa mkpuchi. N'otu oge, obere - ịgbado ọkụ ọkụ na-egbochi iko ahụ ịgbawa n'ihi oke nrụgide okpomọkụ, na-echebe ịdị larịị na iguzosi ike n'ezi ihe nke elu iko. Maka nnukwu iko oghere oghere, igwe ultrasonic soldering irons nwere ike itinye n'ime ahịrị mmepụta ịgbado ọkụ na-akpaghị aka. Ejikọtara ya na nguzozi nke ikpo okwu mgbasa ozi mgbasa ozi, enwere ike nweta ịgbado ọkụ nke ọma na nke edo, na-emeziwanye nrụpụta mmepụta na nkwụsi ike nke ngwaahịa, yana dozie nsogbu nke àgwà na-ekwekọghị ekwekọ na ịgbado ọkụ ọdịnala.

(III) Nkwado kọlụm idozi ịgbado ọkụ

Ọ dị mkpa ka etinye ogidi nkwado ahaziri nke ọma n'ime oghere oghere nke iko oghere iji guzogide nrụgide ikuku dị na mpụga ma gbochie nrụrụ iko. Njikọ dị n'etiti ogidi nkwado na oyi akwa metallized iko ga-enwe ike zuru oke ma ọ naghị emebi akara oghere. Ndozi kọlụm nkwado ọdịnala na-ejikarị njikọ nrapado ma ọ bụ ịgbado ọkụ nkịtị. Njikọ nrapado na-adịkarị mfe ịka nká na ikewapụ, ebe ịgbado ọkụ nkịtị nwere ike imebi iko ma ọ bụ mepụta afụ, na-emetụta nkwụsi ike nke oyi akwa.

Ultrasonic soldering ígwè, na ha kọmpat imewe na kpọmkwem ike akara, nwere ike nweta ezubere iche ịgbado ọkụ nke support ogidi: nkwado kọlụm etinye na a preset ọnọdụ na iko metallization oyi akwa, na soldering n'ọnụ na-kpọmkwem kwekọọ na ala nke nkwado kọlụm. Site na ikpo ọkụ mpaghara na elu-mmụgharị ugboro ugboro, a na-etolite njikọ weld siri ike ngwa ngwa n'etiti kọlụm nkwado na oyi akwa metallization. A na-etinye ebe a na-agbado ọkụ, na-enwe obere mgbasa ọkụ ọkụ, na-egbochi mmebi nke kọlụm nkwado na iko iko. N'otu oge ahụ, nkwonkwo weld dị oke na enweghị oghere, na-eme ka nrụzi siri ike nke kọlụm nkwado na-enweghị emetụta ikuku na iguzosi ike n'ezi ihe nke oyi akwa. Usoro ịgbado ọkụ a na-agbanwe agbanwe iji kwado ogidi nke nha na ihe dị iche iche, na-enye mgbanwe siri ike, ọ dịkwa mma maka idozi ogidi nkwado maka obere iko oghere eji eme ihe n'ụzọ ziri ezi na elu - ngwa ụlọ dị elu.
