Kodi mungasiyanitse bwanji pakati pa njira yodutsa pa dzenje, njira yobisika ndi njira yobisika mu PCB?
Mu kapangidwe ndi kupanga ma PCB, nthawi zambiri timagwiritsa ntchito njira yodutsa m'bowo, yobisika/yobisika kuti tikwaniritse zosowa za kapangidwe ndi zofunikira pakugwira ntchito. Ndiye kusiyana kwake ndi kotani?
1. Kudzera pa dzenje
Bowo lodutsa ndi mtundu wosavuta komanso wofala wa mabowo mu PCB. Limapangidwa pobowola bowo mu PCB (layer kuchokera pamwamba mpaka pansi) ndikudzaza ndi zinthu zoyendetsera magetsi (monga mkuwa). Nthawi zambiri amagwiritsidwa ntchito kulumikiza ma circuits m'magawo osiyanasiyana kuti apereke kulumikizana kwamagetsi ndi chithandizo chamakina.
Mtengo wa through hole ndi wotsika mtengo, koma pakupanga circuit board ya HDI yokhala ndi anthu ambiri, popeza malo a circuit board ndi amtengo wapatali kwambiri, kapangidwe ka through hole ndi kowononga ndalama zambiri.
2. Kudzera mwa osawona
Blind via ndi yofanana ndi bowo lodutsa, koma blind via imadutsa pang'ono mu PCB. Imatsogolera gawo lapamwamba kupita mkati popanda kulowa mu PCB. Nthawi zambiri imagwiritsidwa ntchito kulumikiza ma circuits pakati pa zigawo za pamwamba ndi zamkati, yoyenera kwambiri PCB yokhala ndi zigawo zambiri yokhala ndi malo ochepa. Njira yopangira blind via ndi yovuta kwambiri. Kulephera kulabadira kuya kwa kubowola kungayambitse zovuta pakubowola ma electroplating m'mabowo. Chifukwa chake, zigawo za dera zomwe ziyenera kulumikizidwa zimatha kubowoledwa kaye ngati zili zigawo zosiyana za dera, kenako zonse zimalumikizidwa. Komabe, kugwiritsa ntchito njira iyi kumafuna zida zolondola zoyikira ndi kulinganiza. Chifukwa chake, blind via ndi yokwera mtengo kuposa bowo lodutsa.
3. Anaikidwa m'manda kudzera
Ma vias okwiriridwa amabisika mkati mwa gawo lililonse la PCB ndipo amalumikiza zigawo ziwiri kapena zingapo zamkati mwa PCB. Sawoneka pamwamba ndi pansi. Nthawi zambiri amakhala oyenera ma circuit board a HDI okwera kwambiri kuti awonjezere malo ogwiritsidwa ntchito a zigawo zina za circuit. Pakupanga ma vias okwiriridwa, ntchito zobowola zitha kuchitika kokha pa zigawo za circuit payokha. Gawo lamkati poyamba limalumikizidwa pang'ono kenako limayikidwa ndi electroplated, kenako zonse zimalumikizidwa. Chifukwa njira yogwirira ntchito ndi yovuta kwambiri kuposa yoyamba kudzera pa dzenje ndi blind via, mtengo wake ndi wokwera mtengo.
Malangizo:
Mtengo: Kudzera pa dzenje Kugwiritsa ntchito malo: kudzera pa dzenje Kuvuta kwa ntchito: kudzera pa dzenje Richpcba imapatsa makasitomala ntchito za PCB + SMT zomwe zimayikidwa pa malo amodzi "mtengo wabwino kwambiri, khalidwe lapamwamba, komanso kutumiza mwachangu", kupereka zitsanzo zambiri + kupanga zinthu zambiri, ndikuthetsa zosowa za makasitomala za PCBA zomwe zimayikidwa pa malo amodzi. Zogulitsazi zimagwiritsidwa ntchito kwambiri mu luntha lochita kupanga, zida, zida zolumikizirana, kusungira mphamvu ya photovoltaic, zamagetsi zamagalimoto ndi zina.
