Hal joogsi oo elektaroonig ah soo saaraha guddiga PCBA LED
Alaabooyinka Muhiimka ah
MPCB, PCB-ga biraha ku salaysan, waxa uu ka kooban yahay substrate bir ah (ie Aluminum, Copper ama Stainless Steel ect.,), dielectric kala diri kulaylka iyo wareegga naxaasta.Diidmada kulaylkeeda sare awgeed, MPCB-yada waxaa loo isticmaalaa codsiyo kala duwan.Waxaad ka heli kartaa sahay koronto, nalalka LED-ka ama meel kasta oo kulaylku yahay qodobka ugu weyn.
Tilmaamaha qaab dhismeedka PCB
1.Circuit and design (Qaabka): Wareegga waxaa loo isticmaalaa sidii qalab lagu sameeyo inta u dhaxaysa qaybaha.Naqshadaynta, dusha sare ee naxaasta ah ayaa loo qaabayn doonaa sida lakabka dhulka iyo korontada.Sadar iyo sawiro isku mar ayaa la sameeyaa.
2.Dielectric Layer (Dielectric): Waxaa loo isticmaalaa in lagu ilaaliyo dahaarka u dhexeeya xariiqyada iyo lakabyada, oo badanaa loo yaqaan substrate.
3.Silkscreen (Halyeeyad/Calaamadeynta/Sharashadda Xariir): Tani waa qayb aan muhiim ahayn.Shaqadeeda ugu weyn waa inay calaamadiso magaca iyo booska booska qayb kasta oo ka mid ah guddiga wareegga, kaas oo ku habboon dayactirka iyo aqoonsiga ka dib marka la isku daro.
