Kupyolera mu dzenje: Plating Through Hole amatchedwa PTH
Uwu ndiye mtundu wodziwika kwambiri wa via hole.Muyenera kungotenga PCB ndikuyang'ana kuwala, dzenje lomwe limatha kuwona kuwala kowala ndi "kupyolera mu dzenje".Uwu ndi mtundu wosavuta kwambiri wa dzenje, chifukwa popanga, mumangofunika kugwiritsa ntchito kubowola kapena laser kuti mubowole mwachindunji bolodi ladera, ndipo mtengo wake ndi wotsika mtengo.Koma kumbali ina, zigawo zina zozungulira sizifunikira kulumikiza izi kudzera m'mabowo.Mwachitsanzo, tili ndi nyumba yansanjika zisanu ndi imodzi.Chimbalangondo chogwira ntchito chili ndi ndalama zambiri.Ndinagula zipinda zake zachitatu ndi zachinayi.Kenako, chimbalangondo chogwira ntchitoyo chili pansanjika yachitatu.Masitepe amapangidwa pakati pa chipinda chachinayi kuti azilankhulana wina ndi mzake, ndipo chimbalangondo chogwira ntchito sichiyenera kugwirizanitsa ndi pansi zina.Panthawiyi, ngati masitepe ena apangidwa kuti adutse pansi pa chipinda chilichonse kuchokera pabwalo loyamba mpaka lachisanu ndi chimodzi, adzawonongeka.Ndi bolodi yamakono Inchi golide sayenera kuloledwa.Chifukwa chake ngakhale kudzera m'mabowo ndi otsika mtengo, nthawi zina amagwiritsa ntchito malo ambiri a PCB.
Bowo Lakhungu: Blind Via Hole (BVH) Dera lakunja la PCB limalumikizidwa ndi wosanjikiza wamkati woyandikana ndi dzenje, koma silikudutsa, chifukwa mbali inayo silingawonekere, chifukwa chake imatchedwa "bowo lakhungu".Kuti muwonjezere kugwiritsiridwa ntchito kwa malo a PCB dera lozungulira, njira ya "khungu kudzera" yatulukira.Njira yopangira iyi imafunikira chidwi chapadera pakuya kwa kubowola (Z olamulira) kuti ikhale yolondola, koma njira iyi nthawi zambiri imayambitsa zovuta za electroplating mu dzenje, kotero pafupifupi palibe wopanga adatengera. N'zothekanso kubowola mabowo kwa zigawo zigawo kuti ayenera kugwirizana mu zigawo payekha dera pasadakhale, ndiyeno kumata pamodzi.Bolodi la 2 + 4 layatsidwa, koma izi zimafuna kachipangizo kolondola komanso koyenera. Tengani chitsanzo pamwambapa pogula nyumba.Nyumba ya nsanjika zisanu ndi imodzi ili ndi masitepe okha olumikiza chipinda choyamba ndi chachiwiri, kapena masitepe olumikiza chipinda chachisanu ndi chachisanu ndi chimodzi, chomwe chimatchedwa mabowo akhungu. "Mabowo akhungu" ndi mabowo omwe amatha kuwonedwa kuchokera mbali imodzi ya mawonekedwe a bolodi, koma osati mbali ina ya bolodi.
Kuikidwa m'manda: Kukwiriridwa kudzera pa Hole (BVH) Wosanjikiza aliyense wozungulira mkati mwa PCB amalumikizidwa koma osalumikizidwa ndi gawo lakunja.Izi sizingakwaniritsidwe pobowola pambuyo polumikizana.Iyenera kubowoleredwa pamagawo ang'onoang'ono.Pambuyo wosanjikiza wamkati womangidwa pang'ono, uyenera kupangidwa ndi electroplated musanamangirire kwathunthu.Poyerekeza ndi choyambirira "kupyolera mu dzenje" Ndipo "mabowo akhungu" ndi ovuta kwambiri, choncho mtengo wake ndi wokwera mtengo kwambiri.Njirayi nthawi zambiri imagwiritsidwa ntchito pama board amtundu wa high-density (HDI) kuti awonjezere malo ogwiritsidwa ntchito a zigawo zina zadera.Tengani chitsanzo cha kugula nyumba pamwamba.Nyumba ya nsanjika zisanu ndi imodzi yokha ili ndi masitepe olumikiza chipinda chachitatu ndi chachinayi, chomwe chimatchedwa mabowo okwiriridwa. "Bowo lokwiriridwa" limatanthawuza kuti dzenje silingawonekere kuchokera ku maonekedwe a bolodi, koma dzenje lenilenilo limakwiriridwa mkati mwa gulu la dera.
