6 Layer ENIG FR4 Boima ba Koporo PCB
Crack bothata ba ka hare teteaneng brazing pad
Tlhokahalo ea PCB e boima ea koporo e ntse e eketseha, 'me liphahlo tse ka hare li ntse li fokotseha.Bothata ba ho petsoha ha pad hangata bo etsahala nakong ea ho phunya PCB (haholo-holo bakeng sa likoti tse kholo tse ka holimo ho 2.5mm).
Ho na le sebaka se fokolang sa ntlafatso karolong ea thepa ea mofuta ona oa bothata.Mokhoa oa setso oa ntlafatso ke ho eketsa pad, ho eketsa matla a ho ebola a thepa, le ho fokotsa sekhahla sa ho phunya, joalo-joalo.
Ho ipapisitsoe le tlhahlobo ea moralo oa ts'ebetso ea PCB le thekenoloji, moralo oa ntlafatso o behiloe pele: kalafo ea ho seha koporo (ha ho ekoa lera le ka hare la solder pad, li-circles tse nyane ho feta sekoti li entsoe) li etsoa ho fokotsa matla a ho hula. ea koporo nakong ea ho chekoa.
Ho phunya lesoba le lenyenyane ka 1.0mm ho feta lesoba le hlokehang, ebe o phunya sekoti se tloaelehileng (ho phunya ha bobeli) ho rarolla bothata ba ho phunya botenya ba ka hare.
Lisebelisoa tsa PCB ea koporo e boima
PCB e boima ea koporo e sebelisetsoa merero e fapaneng, mohlala, ho li-transformer tse bataletseng, phetiso ea mocheso, ho hasana ha matla a phahameng, li-converter tsa taolo, joalo-joalo Ho PC, likoloi, sesole le taolo ea mechine.Ho boetse ho sebelisoa palo e kholo ea li-PCB tsa koporo:
Phepelo ea matla le converter ea taolo
