Kodi pali kusiyana kotani pakati pa bolodi lozungulira ndi bolodi?M’yoyo, anthu ambiri amasokoneza matabwa a dera ndi matabwa.Ndipotu kusiyana pakati pa awiriwa ndi kwakukulu.Nthawi zambiri, matabwa ozungulira amatanthawuza ma PCB opanda kanthu, ndiye kuti, matabwa osindikizidwa opanda zigawo zilizonse zoyikidwapo.Bungwe la dera limatanthawuza bolodi losindikizidwa lomwe layikidwa ndi zipangizo zamagetsi ndipo limatha kuzindikira ntchito zabwino.Atha kumvekanso ngati kusiyana pakati pa gawo lapansi ndi bolodi yomalizidwa!
Gulu lozungulira nthawi zambiri limatchedwa PCB, ndipo dzina lake lonse mu Chingerezi ndi:Bungwe la Circuit Board losindikizidwa.Malinga ndi mawonekedwe ake, imatha kugawidwa m'mitundu itatu: bolodi losanjikiza limodzi, bolodi lamitundu iwiri ndi bolodi lamitundu yambiri.Bolodi limodzi lokha limatanthawuza bolodi lozungulira ndi mawaya omwe ali kumbali imodzi, ndipo gulu la mbali ziwiri limatanthawuza bolodi lozungulira ndi mawaya omwe amagawidwa mbali zonse.Mipikisano wosanjikiza limodzi imatanthawuza bolodi la dera lomwe lili ndi mbali zoposa ziwiri;
Ma board ozungulira atha kugawidwa m'magulu atatu akuluakulu malinga ndi mawonekedwe awo: matabwa osinthika, matabwa olimba, ndi matabwa okhazikika.Pakati pawo, matabwa osinthika amatchedwa FPCs, omwe amapangidwa makamaka ndi zinthu zosinthika monga mafilimu a polyester.Ili ndi mawonekedwe a kachulukidwe wamkulu, wopepuka komanso woonda, ndipo amatha kupindika.Ma board olimba nthawi zambiri amatchedwa PCBs.Amapangidwa ndi zinthu zolimba za gawo lapansi monga ma laminates ovala zamkuwa.Pakali pano ndi omwe amagwiritsidwa ntchito kwambiri.Ma board olimba-flex amatchedwanso FPCBs.Amapangidwa ndi bolodi yofewa ndi bolodi yolimba kudzera mu lamination ndi njira zina, ndipo ali ndi makhalidwe a PCB ndi FPC.
Gulu loyang'anira dera nthawi zambiri limatanthawuza gulu lozungulira lomwe lili ndi SMT patch mounting kapena DIP plug-in plug-in zamagetsi zamagetsi, zomwe zimatha kuzindikira ntchito zanthawi zonse.Imatchedwanso PCBA, ndipo dzina lonse la Chingerezi ndi Printed Circuit Board Assembly.Nthawi zambiri pali njira ziwiri zopangira, imodzi ndi ya SMT chip msonkhano, ina ndi DIP plug-in msonkhano, ndipo njira ziwiri zopangira zitha kugwiritsidwanso ntchito kuphatikiza.Chabwino, zomwe tafotokozazi ndizo zonse zomwe zimasiyana pakati pa bolodi la dera ndi bolodi.
