Za Via-In-Pad PCB

The Via-In-Pad PCBs zambiri mabowo akhungu, amene makamaka ntchito kulumikiza wosanjikiza wamkati kapena yachiwiri wosanjikiza kunja kwa HDI PCB ndi wosanjikiza kunja, kuti patsogolo magetsi ntchito ndi kudalirika kwa zinthu zamagetsi, kufupikitsa chizindikiro. mawaya otumizira, amachepetsa kuyanika kwa inductive ndi capacitive reactance ya chingwe chotumizira, komanso kusokoneza kwamkati ndi kunja kwa electromagnetic.

Amagwiritsidwa ntchito kukonzekera.Vuto lalikulu la mabowo a pulagi mumakampani a PCB ndikutuluka kwamafuta kuchokera kumabowo a pulagi, omwe anganene kuti ndi matenda osatha pamsika.Zimakhudza kwambiri khalidwe la kupanga, nthawi yobweretsera komanso mphamvu ya PCB.Pakalipano, ma PCB ambiri apamwamba kwambiri ali ndi mapangidwe amtunduwu.Choncho, makampani PCB ayenera mwamsanga kuthetsa vuto la kutayikira mafuta ku mabowo pulagi

Zambiri Zakutulutsa Mafuta Kuchokera Kudzera Mu Pad Plug Hole

Kutalikirana pakati pa dzenje la pulagi ndi pad: mu njira yeniyeni yopangira ma PCB odana ndi kuwotcherera, kupatula dzenje la mbale ndikosavuta kuthawa.Ena pulagi dzenje ndi zenera katayanitsidwe ndi zosakwana 0.1mm 4mil) ndi pulagi dzenje ndi odana ndi soldering zenera tangential, mphambano mbale ndi zosavuta kukhalapo pambuyo kuchiritsa kutayikira mafuta;

makulidwe a PCB ndi kabowo: makulidwe a mbale ndi kabowo amalumikizana bwino ndi digiri ndi kuchuluka kwa mafuta;

Kapangidwe ka filimu yofananira: pamene Via-In-Pad PCB kapena kabowo kakang'ono kadumphadumpha, filimu yofananirayo nthawi zambiri imapanga malo oyatsira kuwala pawindo (kuti iwonetse inki mu dzenje) "kupewa inkiyo. dzenje lomwe limalowa mu pad panthawi yachitukuko, koma mawonekedwe owunikira ndi ochepa kwambiri kuti akwaniritse zotsatira za kuwonetseredwa, ndipo malo otumizira kuwala ndi aakulu kwambiri kuti athetse mosavuta.Amapanga mafuta obiriwira pa PAD.

Kuchiritsa zinthu: chifukwa mapangidwe translucent mfundo ya Via-In-Pad PCB kwa filimu ayenera kukhala ang'onoang'ono kuposa dzenje, mbali ya inki dzenje ndi wamkulu kuposa translucent mfundo pamene poyera si poyera kuwala.Inki si photosensitive machiritso, chitukuko pambuyo kufunika ambiri kusintha kukhudzana kapena UV kamodzi, kuti kuchiza inki pano.A wosanjikiza kuchiritsa filimu aumbike pamwamba pa dzenje kuteteza matenthedwe kukula kwa inki mu dzenje pambuyo kuchiritsa.Pambuyo pochiritsa, nthawi yayitali ya gawo lotsika la kutentha, ndi kutsika kwa kutentha kwa gawo lochepa la kutentha, ndi kuchepa kwa gawo ndi mlingo wa kutuluka kwa mafuta;

Inki yotsekera: opanga osiyanasiyana a inki fomula yamtundu wosiyanasiyana nawonso adzakhala ndi kusiyana kwina.
