Ihe mejupụtara PCB ceramic bụ ihe mejupụtara seramiiki, oyi akwa njikọ na oyi akwa sekit. N'adịghị ka MCPCB, seramiiki PCB enweghị oyi akwa mkpuchi, na imepụta oyi akwa sekit na mkpụrụ seramiiki siri ike. Kedu otu esi arụ PCB ceramic? Ebe ọ bụ na a na-eji ihe seramiiki mee ihe dị ka ihe ndị na-emepụta PCB, a na-emepụta ụzọ ole na ole iji rụpụta oyi akwa sekit na seramiiki. Ụzọ ndị a bụ HTCC, DBC, ihe nkiri siri ike, LTCC, thin-film, na DPC.

HTCC

Uru: ike nhazi dị elu; elu thermal conductivity; ezigbo nkwụsi ike nke kemịkal; ịdị elu wiring; RoHS kwadoro

Cons: adịghị mma sekit conductivity; elu sintering okpomọkụ; ọnụ ahịa dị oke ọnụ

HTCC bụ mbiri nke seramiiki na-ekpo ọkụ na-ekpo ọkụ. Ọ bụ usoro nrụpụta PCB seramiiki izizi. Ihe seramiiki maka HTCC bụ alumina, mullite, ma ọ bụ aluminom nitride.

Usoro mmepụta ya bụ:

Na 1300-1600 ℃, seramiiki ntụ ntụ (na-enweghị iko agbakwunyere) bụ sintered na akpọnwụwo ka sie ike. Ọ bụrụ na imewe na-achọ site na oghere, oghere na-gbapuru na substrate osisi.

N'otu okpomọkụ ahụ dị elu, a na-agbaze ígwè dị elu na-agbaze dị ka ihe mgbochi ígwè. Igwe a nwere ike ịbụ tungsten, molybdenum, molybdenum, manganese, na ndị ọzọ. Ngwongwo nwere ike ịbụ tungsten, molybdenum, molybdenum, na manganese. A na-ebipụta tapawa ígwè dị ka nhazi ahụ si dị iji mepụta oyi akwa sekit na mkpụrụ sekit.

Na-esote, 4%-8% enyemaka sintering na-agbakwunyere.

Ọ bụrụ na PCB bụ multilayer, n'ígwé na-laminated.

Mgbe ahụ na 1500-1600 ℃, dum Nchikota na-sintered na-etolite seramiiki mbadamba.

N'ikpeazụ, a na-agbakwunye ihe mkpuchi na-ere ahịa iji chebe oyi akwa sekit.

Ihe nkiri seramiiki PCB nrụpụta

Uru: ala nrụpụta okpomọkụ; sekit dị mma; ezigbo elu flatness

ọghọm: akụrụngwa nrụpụta dị oke ọnụ; enweghị ike ịmepụta sekit akụkụ atọ

Igwe ọla kọpa na seramiiki ihe nkiri dị gịrịgịrị PCB nwere ọkpụrụkpụ na-erughị 1mm. Ihe ndị bụ isi seramiiki maka PCB seramiiki dị mkpa bụ alumina na aluminom nitride. Usoro mmepụta ya bụ:

A na-ebu ụzọ hichaa mkpụrụ seramiiki.

N'ọnọdụ enweghị ohere, mmiri dị na mkpụrụ seramiki na-ekpochapụ ọkụ.

Na-esote, a na-emepụta oyi akwa ọla kọpa n'elu ala nke seramiiki site na sputter magnetron.

A na-emepụta ihe oyiyi sekit na oyi akwa ọla kọpa site na teknụzụ fotoresist na-acha odo odo.

Mgbe ahụ, a na-ewepụ ọla kọpa buru ibu site na etching.

N'ikpeazụ, a na-agbakwunye ihe mkpuchi na-ere ahịa iji chebe sekit.

Nchịkọta: emechara ihe nkiri seramiiki PCB dị gịrịgịrị na ọnọdụ agụụ. Teknụzụ lithography na-acha odo odo na-enye ohere nkenke nkenke na sekit. Agbanyeghị, imepụta ihe nkiri dị mkpa nwere oke na ọkpụrụkpụ ọla kọpa. PCB seramiiki dị obere dabara adaba maka nkwakọ ngwaahịa dị elu yana ngwaọrụ dị obere.

DPC

Uru: enweghị oke na ụdị seramiiki na ọkpụrụkpụ; sekit dị mma; obere okpomọkụ nrụpụta; ezigbo elu flatness

ọghọm: akụrụngwa nrụpụta dị oke ọnụ

DPC bụ mbiri nke ọla kọpa kwụ ọtọ. Ọ na-etolite site na usoro mmepụta seramiiki dị mkpa ma na-emeziwanye site n'ịgbakwụnye ọla kọpa site na ịkwanye. Usoro mmepụta ya bụ:

Otu usoro mmepụta ihe nke mmepụta ihe nkiri dị mkpa ruo mgbe a na-ebipụta ihe oyiyi sekit na ihe nkiri ọla kọpa.

A na-agbakwunye ọkpụrụkpụ ọla kọpa sekit site na ịkwanye.

A na-ewepụ ihe nkiri ọla kọpa.

N'ikpeazụ, a na-agbakwunye ihe mkpuchi na-ere ahịa iji chebe sekit.
