China Multilayer PCB Fabrication

Kuchokera kumitundu yosinthika kupita kumitundu yodabwitsa,Ma PCBzakhala zosiyanasiyana m'dziko lamakono lamagetsi.Makamaka otchuka, komabe, alima PCB ambiri.Kuchokera pamalingaliro aukadaulo, ma PCB ambiri ali ndi maubwino angapo potengera kapangidwe kake.Ubwino wa ma PCB amitundu yambiri ndi awa:

Kukula Kwakung'ono: Chimodzi mwazinthu zodziwika bwino komanso zoyamikiridwa kwambiri zogwiritsa ntchito ma PCB ambiri ndi kukula kwawo.Chifukwa cha kapangidwe kake, ma PCB ambiri ndi ang'onoang'ono kuposa ma PCB ena omwe ali ndi magwiridwe antchito ofanana.Izi zimabweretsa phindu lalikulu pazamagetsi zamakono chifukwa momwe zinthu zilili pano zikulowera ku zida zazing'ono, zophatikizika koma zamphamvu kwambiri monga mafoni am'manja, laputopu, mapiritsi ndi zovala.

Kumanga kopepuka: Ndi ma PCB ang'onoang'ono, kulemera kwake kumakhala kotsika, makamaka popeza zolumikizira zingapo zomwe zimafunikira kuti zilumikize ma PCB osanjikiza amodzi ndi awiri osanjikiza amachotsedwa, mokomera mapangidwe amitundu yambiri.Apanso, izi ndi zabwino kwa zamagetsi zamakono, zomwe zimatsamira kwambiri pakuyenda.

Ubwino Wapamwamba: Chifukwa cha kuchuluka kwa ntchito ndi mapulani omwe amayenera kuchitidwa popanga ma PCB amitundu yambiri, ma PCB amtunduwu amakonda kugwira ntchito bwino kuposa ma PCB osanjikiza amodzi komanso osanjikiza awiri.Choncho, iwonso ndi odalirika kwambiri.

Kukhazikika Kwabwino: Ma PCB a Multilayer amakhala olimba mwachilengedwe chawo.Sikuti ma PCB a multilayer awa ayenera kukhala ndi kulemera kwawo, komanso amayenera kuthana ndi kutentha ndi kukakamizidwa komwe kumagwiritsiridwa ntchito kuwalumikiza pamodzi.Kuphatikiza pazifukwa izi, ma PCB amitundu yambiri amagwiritsa ntchito zigawo zingapo za kutchinjiriza pakati pa zigawo zozungulira, kuzilumikiza pamodzi ndi zomatira za prepreg ndi zida zoteteza.

Kusinthasintha kowonjezereka: Ngakhale izi sizikugwira ntchito pamisonkhano yonse ya multilayer PCB, ena amagwiritsa ntchito njira zomangira zosinthika, zomwe zimapangitsa ma PCB osinthika ambiri.Izi zitha kukhala zofunika kwambiri pamachitidwe omwe mapindikira pang'ono ndi mapindika amatha kuchitika pafupipafupi.Apanso, izi sizikugwira ntchito ku ma PCB onse amitundu yambiri, ndipo zigawo zambiri zomwe mumawonjezera ku PCB yosinthika, PCB idzakhala yosasinthika.

Zamphamvu kwambiri: Multilayer PCBs ndi zigawo zolimba kwambiri zomwe zimaphatikiza magawo angapo kukhala PCB imodzi.Mipata yapafupi imeneyi imapangitsa matabwa kukhala ogwirizana kwambiri, ndipo mphamvu zawo zamagetsi zomwe zimapangidwira zimawathandiza kuti akwaniritse mphamvu zambiri komanso kuthamanga, ngakhale kuti ndi ochepa.

Single Connection Point: A Multilayer PCB adapangidwa kuti azigwira ntchito ngati gawo limodzi, osati motsatizana ndi zigawo zina za PCB.Chifukwa chake, ali ndi malo amodzi olumikizira m'malo molumikizana ndi ma PCB angapo osanjikiza.Izi zimatsimikiziranso zopindulitsa muzopanga zamagetsi zamagetsi, chifukwa zimangofunika kuphatikizira malo amodzi olumikizirana pazomaliza.Izi ndizothandiza makamaka pamagetsi ang'onoang'ono ndi zida zomwe zimapangidwira kuchepetsa kukula ndi kulemera kwake.

Ubwinowu umapangitsa ma PCB ambiri kukhala othandiza pamagwiritsidwe osiyanasiyana, makamaka zida zam'manja ndi zamagetsi zogwira ntchito kwambiri.Komanso, ma PCB amitundu yambiri akupeza malo awo pakuchulukirachulukira kwa ntchito zenizeni zamakampani pomwe mafakitale ambiri amatembenukira ku mayankho amafoni.
