4 Layer ENIG Impedance Half Hole PCB

The enieni metallized theka dzenje adzakhala kukonzedwa motere: onse metallized theka dzenje PCB mabowo adzakhala mokhomerera pobowola pobowola pambuyo kujambula plating ndi pamaso etching, dzenje limodzi adzakhala mokhomerera pa mphambano mfundo kumapeto onse a theka la dzenje.

1) Pangani njira ya MI molingana ndiukadaulo,

2) chitsulo theka dzenje ndi kubowola (kapena gong kunja), chithunzi pambuyo plating, pamaso etching awiri kubowola theka dzenje, ayenera kuganizira mawonekedwe a gong poyambira sangavumbulutse mkuwa, kubowola theka dzenje kusuntha unit,

3) Bowo lakumanja (bowola theka)

A. Boworani choyamba, ndiyeno mutembenuzire mbale (kapena galasi lolunjika);Boolani kumanzere

B. Cholinga ndikuchepetsa kukokera kwa mpeni wobowola pa mkuwa womwe uli mkati mwa dzenjelo, zomwe zimapangitsa kuti mkuwa uwonongeke.

4) Malinga ndi katalikirana kwa mzere wa contour, kukula kwa bowo la bowo la dzenje kumatsimikiziridwa.

5) Jambulani kukana kuwotcherera filimu, ndi gongs ntchito monga kutsekereza mfundo kutsegula zenera ndi kukulitsa zenera ndi 4mil.
