Ma multilayer circuit board ali ndi mitundu yambiri yogwirira ntchito, monga: chitetezo, silika screen layer, sign layer, internal layer, etc. Kodi mumadziwa bwanji za zigawozi?Ntchito za gawo lililonse ndizosiyana, tiyeni tiwone zomwe ntchito za gawo lililonse zikuyenera kuchita!

Kuteteza wosanjikiza: ntchito kuonetsetsa kuti malo pa bolodi dera kuti safuna malata plating si malata, ndipo PCB dera bolodi wapangidwa kuonetsetsa kudalirika kwa ntchito gulu dera.Pakati pawo, Paste Pamwamba ndi Pansi Pansi ndi gawo lapamwamba lachigoba cha solder ndi chigoba cham'munsi cha solder, motsatana.Top Solder ndi Pansi Solder ndi gawo la chitetezo cha solder phala ndi pansi pa solder phala chitetezo wosanjikiza, motero.

Chidziwitso chatsatanetsatane cha bolodi yozungulira ya PCB yamitundu yambiri komanso tanthauzo la gawo lililonse
Chophimba cha silika - chomwe chimagwiritsidwa ntchito kusindikiza nambala ya serial, nambala yopangira, dzina la kampani, chitsanzo cha logo, ndi zina za zigawo zomwe zili pa bolodi la dera.

Chingwe cha chizindikiro - chomwe chimagwiritsidwa ntchito poyika zigawo kapena mawaya.Protel DXP nthawi zambiri imakhala ndi zigawo zapakati za 30, zomwe ndi Mid Layer1 ~ Mid Layer30, gawo lapakati limagwiritsidwa ntchito pokonza mizere yazizindikiro, ndipo zigawo zapamwamba ndi zapansi zimagwiritsidwa ntchito kuyika zigawo kapena mkuwa.

Wosanjikiza wamkati - wogwiritsidwa ntchito ngati njira yolowera chizindikiro, Protel DXP ili ndi zigawo 16 zamkati.

Zida zonse za PCB za akatswiri opanga PCB ziyenera kuwunikiridwa mosamala ndikuvomerezedwa ndi dipatimenti yaumisiri isanadulidwe ndikupanga.Mlingo wodutsa pa bolodi lililonse ndi wokwera mpaka 98.6%, ndipo zinthu zonse zadutsa chiphaso cha chilengedwe cha RROHS ndi United States UL ndi ziphaso zina zofananira.
