4 Txheej ENIG ib nrab qhov PCB 12026

Hlau ib nrab-qhov PCB tom qab tsim lub qhov phab ntsa tooj liab dub, burr seem, qhov sib txawv tau ua teeb meem nyuaj hauv txheej txheem txheej txheem ntawm PCB Hoobkas. Tshwj xeeb tshaj yog tag nrho cov kab ntawm ib nrab qhov zoo ib yam li lub thwj qhov, lub qhov taub yog li 0.6 hli, qhov phab ntsa qhov sib nrug yog 0.45 hli, cov duab sab nraub qaum yog 2 hli, vim tias qhov sib nrug me me, nws yooj yim ua rau luv Circuit Court vim tias ntawm daim tawv nqaij tooj liab

Kev siv dav hlau ib nrab-qhov PCB txoj hauv kev yog CNC milling tshuab gongs, tshuab xuas nrig ntaus tshuab xuas nrig ntaus, V-CUT txiav thiab lwm yam, cov txheej txheem ua hauv kev tshem tawm qhov xav tau ib feem ntawm lub qhov ua tooj liab, tsis tuaj yeem ua rau tshuav ib feem ntawm PTH qhov seem ntawm cov tooj liab uas seem, burr, qhov loj ntawm phab ntsa tooj liab daim tawv nqaij warp, tev tshwm sim. ntawm qhov tod tes, thaum cov hlau ib nrab qhov raug tsim, vim muaj kev cuam tshuam ntawm PCB nthuav dav thiab ntsws, qhov chaw raug thiab ua kom raug, qhov sib txawv me me ntawm qhov ib nrab qhov nyob ntawm sab laug thiab sab xis ntawm tib chav loj , uas coj teeb meem loj rau kev sib dhos vuam.
