2 Txheej HASL FR4 Ib Nrab Qhov PCB

Hlau ib nrab qhov (groove) yog lub qhov tom qab lub qhov tom qab qhov thib ob drilling, txheej txheem, thiab thaum kawg khaws cov hlau qhov (groove) ib nrab, tsuas yog hais tias phaj ntug metallized qhov txiav ib nrab, phaj ntug semi-metallic qhov txheej txheem yog ib txoj kev paub tab heev.

Yuav tswj cov khoom zoo li cas tom qab tsim lub semi-metallic qhov ntawm ntug ntawm lub phaj.Xws li lub qhov phab ntsa tooj liab prickle, residual tau ib tug txheej txheem nyuaj.Ib kab tag nrho ntawm ib nrab-metallized qhov nyob rau ntawm ntug ntawm cov phiaj PCB, uas yog ib qho me me aperture, feem ntau yog siv rau ntawm lub rooj tsavxwm, raws li ib tug subplate ntawm ib tug tswv phaj, los ntawm uas lub semi-metallized qhov yog welded rau lub pins ntawm lub master phaj thiab cov khoom.

Yog hais tias muaj tooj liab spines nyob rau hauv lub semi-metallized qhov, thaum lub chaw tsim tshuaj paus welding, nws yuav ua rau lub vuam ko taw tsis ruaj khov, virtual vuam, loj yuav ua rau choj ntawm ob pins luv luv Circuit Court.Ob qho tib si drilling thiab milling, cov kev taw qhia ntawm kev sib hloov ntawm SPINDLE yog clockwise, tiv thaiv qhov txuas ntxiv ntawm txheej metallization thaum ua thiab kev sib cais ntawm txheej metallization los ntawm lub qhov phab ntsa, thiab xyuas kom meej tias tooj liab spines thiab residues yuav tsis raug tsim tom qab ua tiav. .Yuav kom loj dua qhov chaw khoob khoob khoob.
