Kuchokera pa bolodi lamitundu yambiri mpaka kapangidwe ka phiri la mbali ziwiri, cholinga chathu ndikukupatsani chinthu chabwino chomwe chimakwaniritsa zomwe mukufuna ndipo ndichotsika mtengo kwambiri kupanga.
Zomwe takumana nazo pamiyezo ya IPC Class III, zofunikira zaukhondo kwambiri, kulolerana kwa mkuwa wolemera ndi kupanga zimatipatsa mwayi wopatsa makasitomala athu zomwe amafunikira pazogulitsa zawo.
Zaukadaulo wapamwamba:
Ndege zakumbuyo, ma board a HDI, ma board okwera kwambiri, ma TG board apamwamba, ma board opanda halogen, ma board osinthika komanso osasunthika, ma hybrids ndi ma board aliwonse okhala ndi zida zapamwamba kwambiri.
20-wosanjikiza PCB, 2 mil mzere m'lifupi katalikirana:
Kupanga kwathu kwazaka 10, zida zolondola kwambiri komanso zida zoyesera zimathandizira VIT kupanga ma board olimba osanjikiza 20 ndi ma frequency okhazikika mpaka magawo 12.
Makulidwe a ndege yakumbuyo mpaka .276 (7mm), magawo mpaka 20:1, 2/2 mzere/malo ndi mapangidwe oyendetsedwa ndi impedance amapangidwa tsiku lililonse.
Zogulitsa ndi ukadaulo kugwiritsa ntchito:
Lemberani pazolumikizana, zakuthambo, chitetezo, IT, zida zamankhwala, zida zoyesera zolondola komanso makampani owongolera mafakitale
Miyezo yokhazikika pakukonza ma PCB:kuyendera ndi kuyesa kudzakhazikitsidwa pa IPC-A-600 ndi IPC-6012, kalasi 2 pokhapokha ngati zafotokozedwa pazithunzi zamakasitomala kapena mawonekedwe.
PCB Design Service:VIT imathanso kupereka ntchito yopangira PCB kwa makasitomala athu
Nthawi zina, makasitomala athu amangotipatsa fayilo ya 2D kapena lingaliro chabe, ndiye tidzapanga PCB, masanjidwe ndikupanga fayilo ya Gerber kwa iwo.
