4 Igice cya ENIG igice cyumwobo PCB 12026

Icyuma cya kimwe cya kabiri PCB nyuma yo gukora urukuta rw'umwobo umuringa wirabura, burr ibisigara, gutandukana byabaye ikibazo kitoroshye muburyo bwo kubumba uruganda rwa PCB. Cyane cyane umurongo wose wibice bibiri bisa nkibyobo bya kashe, aperture igera kuri mm 0,6, intera yurukuta rwumwobo ni 0,45 mm, intera yinyuma ni mm 2, kubera ko intera ari nto cyane, biroroshye gutera inzira ngufi kuko y'uruhu rw'umuringa.

Uburyo rusange bwa metallised half-hole PCB uburyo bwo gukora ni imashini ya CNC yo gusya, imashini ikubita imashini, gukata V-CUT nibindi, ubu buryo bwo gutunganya mugukuraho ibikenewe igice cyumwobo kugirango ukore umuringa, ntibishobora kuganisha kuri igice gisigaye cyumwobo wa PTH cyurugero rwumuringa usigaye, burr, umwobo ukomeye urukuta rwumuringa uruhu rwumuringa, gukuramo ibintu. kurundi ruhande, iyo hashyizweho umwobo wa kimwe cya kabiri, bitewe ningaruka zo kwaguka kwa PCB no kugabanuka, aho umwobo uhagaze neza kandi ugakora neza, ubunini bwatandukanijwe nigice cyasigaye igice cyibumoso gisigaye kuruhande rwibumoso niburyo bwigice kimwe ni kinini , bizana ibibazo bikomeye munteko yo gusudira.
