Awiri-mbali mbali dera gulu makamaka kuthetsa dera zovuta kapangidwe ndi malire dera, mbali zonse za gulu anaika zigawo zikuluzikulu, awiri wosanjikiza kapena Mipikisano wosanjikiza wiring.Double-mbalima PCBs nthawi zambiri ntchito makina vending, mafoni, UPS machitidwe. , ma amplifiers, makina owunikira, ndi ma dashboard amagalimoto.Ma PCB okhala ndi mbali ziwiri ndi abwino kwambiri paukadaulo wapamwamba kwambiri, ma compact electronic circuits, ndi ma circuit ovuta.Ntchito yake ndi yotakata kwambiri ndipo mtengo wake ndi wotsika.

2-wosanjikiza PCB ndi mkuwa yokutidwa mbali zonse ndi insulating wosanjikiza pakati.Ili ndi zigawo mbali zonse za bolodi, ndichifukwa chake imatchedwanso PCB yokhala ndi mbali ziwiri.Amapangidwa pophatikiza zigawo ziwiri zamkuwa pamodzi, ndi zida za dielectric pakati.
Mutha kuyerekeza kuti kusiyana komwe kuli pakati pa zigawo ziwiri za PCB ndi zigawo 4 za PCB malinga ndi mayina awo.2 zigawo PCB ali kuda m'mbali ziwiri ndi wosanjikiza pamwamba ndi pansi, pamene 4 zigawo PCB ali 4 zigawo.Ngati mumamvetsetsa bwino mitundu iwiri ya matabwa a PCB, mudzapeza kuti pali kusiyana kwakukulu momwe amamangidwira komanso momwe angagwiritsire ntchito.
Zotsatira za PCB za mbali imodzi zimapezeka mbali imodzi yokha, pomwe ma PCB a mbali ziwiri ali ndi zotsata mbali zonse ndi zigawo zapamwamba ndi zapansi.Zomwe zili ndi mkuwa wochititsa chidwi zimayikidwa mbali zonse za PCB ya mbali ziwiri, ndipo izi zimatsogolera ku mphambano kapena kuphatikizika kwa njirayo.
Inde, ingotitumizirani fayilo yanu ya gerber.

The2 gawo PCB(PCB yokhala ndi mbali ziwiri) ndi bolodi losindikizidwa lokhala ndi mkuwa wokutidwa mbali zonse, pamwamba ndi pansi.Pali insulating wosanjikiza pakati, amene ambiri ntchito kusindikizidwa dera bolodi.Mbali zonse ziwiri zikhoza kukhala masanjidwe ndi soldered, zomwe zimachepetsa kwambiri zovuta za masanjidwe, choncho amagwiritsidwa ntchito kwambiri.
Kuti mugwiritse ntchito mabwalo kumbali zonse ziwiri, payenera kukhala kugwirizana koyenera kwa dera pakati pa mbali ziwirizo."Milatho" pakati pa madera oterewa amatchedwa vias.A kudzera ndi dzenje laling'ono pa bolodi PCB wodzazidwa kapena wokutidwa ndi zitsulo, amene akhoza chikugwirizana ndi mabwalo mbali zonse.Chifukwa chakuti malo a bolodi lokhala ndi mbali ziwiri ndi lalikulu kawiri kuposa la bolodi lokhala ndi mbali imodzi, bolodi lokhala ndi mbali ziwiri limathetsa vuto la bolodi lokhala ndi mbali imodzi chifukwa cha mapangidwe osakanikirana (akhoza kugwirizanitsidwa ndi mbali inayo). kudzera m'mabowo), ndipo ndi yabwino kwa mabwalo ovuta kwambiri kuposa bolodi lambali imodzi.
Timafunikira zinthu zamagetsi zomwe zimakhala ndi ntchito zambiri, kukula kochepa, ndi ntchito zambiri, zomwe zimalimbikitsa chitukuko cha makina osindikizira ozungulira kuti akhale opepuka, ochepa, ochepa komanso ochepa.Pokhala ndi malo ochepa, ntchito zambiri zimatha kukwaniritsidwa, kachulukidwe kamangidwe kakula, ndipo m'mimba mwake mwake ndi wocheperako.The osachepera dzenje awiri mphamvu makina kubowola watsika kuchokera 0.4mm kuti 0.2mm kapena ngakhale ang'onoang'ono.Dyenje la dzenje la PTH likucheperachepera.Ubwino wa PTH (Plated Through Hole) umene kugwirizanitsa kwa wosanjikiza ndi wosanjikiza kumadalira mwachindunji ndi kudalirika kwa bolodi losindikizidwa.
