Cholumikizira cha PCB champhamvu kwambiri kuti chithandize zipangizo zanzeru kukhala ndi mphamvu zambiri

Bolodi la PCB (Printedcircuitboard) ndi gulu lothandizira zigawo zamagetsi komanso lothandizira kulumikizana pakati pa zigawo zamagetsi ndi zigawo zamagetsi. Ndi pafupifupi zomangamanga za zipangizo zonse zanzeru. Kuwonjezera pa ntchito zoyambira zokonza zigawo zazing'ono zamagetsi, ntchito yofunika kwambiri ndikupereka kulumikizana kwa zigawo zamagetsi zomwe zili pamwambapa.

Kodi zigawo za bolodi la PCB ndi ziti?

Bolodi la PCB limapangidwa makamaka ndi cholumikizira cholumikizira, dzenje lodutsa, dzenje loyikira, waya, zigawo, zolumikizira, zodzaza, malire amagetsi ndi zina zotero.

(1) Pad: dzenje lachitsulo lomwe limagwiritsidwa ntchito polumikiza mapini a zigawo.

(2) Kudutsa m'mabowo: pali chitsulo kudzera m'mabowo ndi chosakhala chitsulo kudzera m'mabowo, momwe chitsulo kudzera m'mabowo chimagwiritsidwa ntchito kulumikiza mapini a zigawo pakati pa gawo lililonse.

(3) Bowo loyikira: limagwiritsidwa ntchito kukonza bolodi la dera.

(4) Kondakitala: filimu ya mkuwa ya netiweki yamagetsi yomwe imagwiritsidwa ntchito kulumikiza mapini a zigawo.

(5) Zolumikizira: zigawo zomwe zimagwiritsidwa ntchito polumikiza mabwalo amagetsi.

(6) Kudzaza: kugwiritsa ntchito mkuwa pa netiweki ya waya pansi kungachepetse bwino kupondereza kwa waya.

(7) Malire amagetsi: amagwiritsidwa ntchito kudziwa kukula kwa bolodi la dera, zigawo za bolodi sizingapitirire malire.

Bolodi ya PCB malinga ndi kapangidwe kake ingagawidwe m'magulu awiri a PCB, gulu la PCB lawiri, bolodi la PCB lambiri; bolodi lambiri lambiri ndi lachinayi, bolodi la magawo asanu ndi limodzi, bolodi lovuta la PCB lambiri limatha kufikira zigawo zoposa khumi.

Ma PCB board ambiri akamakula, mphamvu zamagetsi zimakhala zokhazikika komanso zodalirika, ndipo mtengo wake umakwera. Kusiyana kwa mtengo wa ma board amodzi ndi awiri sikokulirapo. Ngati palibe chofunikira chapadera, mafakitale onse amasankha ma board awiri. Kupatula apo, magwiridwe antchito ndi kukhazikika kwa ma board awiri ndikwabwino kuposa a board imodzi.

Mu PCB multilayer board, tsopano makampaniwa ndi omwe amagwiritsidwa ntchito kwambiri kapena anayi, asanu ndi limodzi, makampani amagetsi ogwiritsa ntchito omwe ali ndi PCB board yapamwamba ndi ambiri. Ngakhale kuti ma multilayer panels ali ndi ubwino wambiri kuposa ma dual panels pakugwira ntchito, kukhazikika, phokoso ndi zina, mabizinesi ambiri ndi mainjiniya amakondabe ma dual panels kuti aganizire za mtengo wake.

Pamene zipangizo zanzeru zikuchulukirachulukira, zowonjezera zambiri zimafunika, zomwe zimapangitsa kuti ma circuit ndi zowonjezera zikhale zochepa kwambiri pa PCB. Nthawi yomweyo, zofunikira paubwino wa zolumikizira za PCB board zapamwamba zimawongoleredwanso. Bolodi laling'ono la PCB silingochepetsa mtengo wokha, komanso lingathandize kupanga PCB board mosavuta, kotero kuti kutayika kwa chizindikiro cha transmission circuit kukhale kochepa.

Cholumikizira cha PCB champhamvu kwambiri ndi kukula kwa chigongono chokha, ndipo cholumikiziracho chimakutidwa ndi siliva ndi mkuwa wofiira, zomwe zimapangitsa kuti cholumikiziracho chigwire bwino ntchito. Ngakhale chaching'ono chingakhale ndi mphamvu zambiri zonyamulira, kuonetsetsa kuti dera likuyenda bwino, komanso njira zosiyanasiyana zoyikira zimatha kukwaniritsa zosowa za makasitomala osiyanasiyana a PCB board.

Amass ili ndi kutalika kosiyanasiyana kwa zolumikizira za ma PCB circuit board okhala ndi makulidwe osiyanasiyana, zomwe zimagwirizana ndi muyezo wamakampani wa makulidwe a panel owonekera a 1.0-1.6mm kuti zitsimikizire kuti zida zikugwiritsidwa ntchito mwachizolowezi!
