Njira yopanga ma board a multilayer nthawi zambiri imachitidwa ndi zojambula zamkati zamkati poyamba, kenako ndikusindikiza ndi kusindikiza njira yopangira gawo limodzi kapena mbali ziwiri, ndikulowa mugawo losankhidwa pakati, kenako ndikutenthetsa, kukanikiza ndi kumangiriza, pobowola wotsatira ndi chimodzimodzi ngati mbali ziwiri plating kudzera-dzenje njira.
1. Choyamba, bolodi la dera la FR4 liyenera kupangidwa poyamba.Pambuyo poyala mkuwa wopangidwa ndi perforated mu gawo lapansi, mabowowo amadzazidwa ndi utomoni ndipo mizere ya pamwamba imapangidwa ndi subtractive etching.Sitepe iyi ndi yofanana ndi gulu lonse la FR4 kupatula kudzaza ma perforations ndi utomoni.
2. Photopolymer epoxy resin imagwiritsidwa ntchito ngati gawo loyamba la kusungunula FV1, ndipo itatha kuyanika, photomask imagwiritsidwa ntchito pa sitepe yowonekera, ndipo pambuyo powonekera, zosungunulira zimagwiritsidwa ntchito popanga dzenje lapansi la dzenje la msomali.Kuumitsa kwa utomoni kumachitika pambuyo potsegula dzenje.
3. Epoxy utomoni pamwamba ndi roughened ndi permanganic acid etching, ndipo pambuyo kukokera, wosanjikiza mkuwa amapangidwa pamwamba ndi electroless mkuwa plating sitepe wotsatira mkuwa plating.Pambuyo plating, wosanjikiza kondakitala mkuwa amapangidwa ndi wosanjikiza m'munsi amapangidwa ndi subtractive etching.
4. Wokutidwa ndi gawo lachiwiri la kutchinjiriza, pogwiritsa ntchito njira zomwezo zachitukuko kuti apange dzenje la bawuti pansi pa dzenje.
5. Ngati kufunika perforation, mungagwiritse ntchito pobowola mabowo kupanga perforations pambuyo mapangidwe mkuwa electroplating etching kupanga waya.
mu wosanjikiza wakunja wa bolodi dera yokutidwa ndi odana malata utoto, ndi ntchito kukhudzana chitukuko njira kuwulula kukhudzana gawo.
6. Ngati chiwerengero cha zigawo chikuwonjezeka, makamaka bwerezani masitepe omwe ali pamwambawa.Ngati pali zigawo zina kumbali zonse ziwiri, choyikapo chotchinga chiyenera kuphimbidwa mbali zonse za maziko, koma plating ikhoza kuchitidwa mbali zonse nthawi imodzi.
