10 Txheej ENIG Multilayer FR4 PCB

PCB tau tsim los ntawm ib sab mus rau ob sab thiab multilayer, thiab kev faib ua feem ntawm multilayer PCB yog nce txhua xyoo.Kev ua haujlwm ntawm multilayer PCB yog tsim los rau siab precision, ntom thiab zoo.Lamination yog txheej txheem tseem ceeb hauv multilayer PCB manufacturing.Kev tswj ntawm lamination zoo tau dhau los ua qhov tseem ceeb.Yog li ntawd, txhawm rau kom ntseeg tau tias qhov zoo ntawm multilayer laminate, peb yuav tsum muaj kev nkag siab zoo ntawm cov txheej txheem multilayer laminate.Yuav ua li cas los txhim kho qhov zoo ntawm multilayer laminate?

1. Lub thickness ntawm cov tub ntxhais phaj yuav tsum tau xaiv raws li tag nrho cov thickness ntawm multilayer PCB.Lub thickness ntawm cov tub ntxhais phaj yuav tsum zoo ib yam, qhov sib txawv me me, thiab cov kev taw qhia txiav yog zoo ib yam, thiaj li tiv thaiv tsis tsim nyog phaj dabtsi yog khoov.

2. Yuav tsum muaj qee qhov kev ncua deb ntawm qhov loj ntawm lub phaj tub ntxhais thiab chav tsev zoo, uas yog, qhov kev ncua deb ntawm chav tsev zoo thiab lub phaj ntug yuav tsum loj npaum li qhov ua tau yam tsis muaj nkim khoom.

3. Yuav kom txo tau qhov sib txawv ntawm cov khaubncaws sab nraud povtseg, kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tsim ntawm qhov chaw nyob.Txawm li cas los xij, qhov ntau dua ntawm qhov tsim qhov chaw, qhov rivet thiab lub qhov cuab yeej yog, qhov ntau ntawm cov tsim qhov yog, thiab txoj hauj lwm yuav tsum nyob ze rau sab li sai tau.Lub hom phiaj tseem ceeb yog kom txo qis qhov sib txawv ntawm qhov sib txawv ntawm cov khaubncaws sab nraud povtseg thiab tawm ntau qhov chaw rau kev tsim khoom.

4. Lub hauv paus tseem ceeb ntawm lub rooj tsavxwm yuav tsum tsis txhob qhib, luv luv, qhib Circuit Court, oxidation, huv board nto thiab residual zaj duab xis.
