1. Kutheni i-BGA ibekwe kumngxuma wemaski we-solder?Uthini umgangatho wokwamkela?Re: Okokuqala, i solder imaski iplagi umngxuma kukukhusela ubomi benkonzo ye via, kuba umngxuma efunekayo kwisithuba BGA jikelele encinane, phakathi 0.2 kunye 0.35mm.Enye isiraphu akulula ukuba yomiswe okanye ibe ngumphunga, kwaye kulula ukushiya iintsalela.Ukuba imaski yesolder ayiplagi umngxuma okanye iplagi...

Kukho iibhodi zeesekethe ezinecala elinye, elinamacala amabini kunye ne-multi-layer.Inani leebhodi ze-multi-layer alikhawulelwanga.Ngoku kukho ngaphezu kwe-100-layer PCBs.IiPCBs eziqhelekileyo ezinomaleko obuninzi zine umaleko kunye neebhodi ezintandathu.Ke kutheni abantu benombuzo othi "Kutheni iibhodi zePCB ezininzi zingamanani alinganayo? Xa sithetha ngokuthelekisekayo, iiPCB ezinamanani alinganayo zineePCB ezingaphaya kwamanani angaqhelekanga, ...

Kutheni ibhodi yesekethe eprintiweyo idinga ulawulo lwe-impedance?Kumgca wesiginali yothumelo yesixhobo sombane, ukuxhathisa okufunyenweyo xa isiginali ye-frequency ephezulu okanye i-electromagnetic wave propagate ibizwa ngokuba yi-impedance.Kutheni le nto iibhodi zePCB kufuneka zingasebenzi ngexesha lenkqubo yokwenziwa komzi-mveliso webhodi yesekethe?Makhe sihlalutye kwezi zizathu zine zilandelayo: 1. Ibhodi yesekethe yePCB ye ...
