Yuav ua li cas thiaj tsim tau qhov kev nyab xeeb ntawm PCB?
Hluav taws xob cuam tshuam txog kev nyab xeeb
1. Qhov sib txawv ntawm Circuit Court.
Rau lub peev xwm ua, qhov tsawg kawg nkaus qhov sib nrug ntawm cov xov hlau yuav tsum tsis pub tsawg tshaj 4mil. Mini kab sib nrug yog qhov kev ncua deb ntawm kab mus rau kab thiab kab mus rau ncoo. Rau kev tsim khoom, nws loj dua thiab zoo dua, feem ntau nws yog 10mil.
2.Pad lub qhov taub thiab dav
Txoj kab uas hla ntawm lub ncoo yuav tsum tsis pub tsawg tshaj 0.2 hli yog tias lub qhov yog mechanically drilled, thiab tsis tsawg tshaj li 4mil yog hais tias lub qhov yog laser drilled. Thiab lub qhov taub qhov siab ntev yog qhov sib txawv me ntsis raws li lub phaj, feem ntau tuaj yeem tswj tau hauv 0.05mm, qhov tsawg kawg nkaus ntawm lub ncoo yuav tsum tsis pub tsawg dua 0.2mm.
3.Qhov sib nrug ntawm Pads
Qhov sib nrug yuav tsum tsis pub tsawg tshaj 0.2 hli los ntawm lub ncoo rau hauv ncoo.
4.Qhov sib nrug ntawm tooj liab thiab ntug ntawm lub rooj tsavxwm
Qhov kev ncua deb ntawm tooj liab thiab PCB ntug yuav tsum tsis pub tsawg tshaj 0.3 hli. Teem txoj cai sib nrug ntawm cov khoom nyob rau hauv nplooj ntawv Tsim-Cov Cai-Board daim duab
Yog tias cov tooj liab tau muab tso rau ntawm thaj chaw loj, yuav tsum muaj qhov kev ncua deb ntawm lub rooj tsavxwm thiab ntug, uas feem ntau yog teem rau 20mil.In PCB tsim thiab kev lag luam kev lag luam, feem ntau, rau lub hom phiaj ntawm txhua yam ntawm cov khoom siv. ua tiav Circuit Board, los yog kom tsis txhob muaj qhov tshwm sim ntawm coiling los yog hluav taws xob luv luv Circuit Court vim tooj liab ntawm daim tawv nqaij raug rau ntawm ntug ntawm lub rooj tsavxwm, engineers feem ntau txo cov tooj liab thaiv nrog ib tug loj cheeb tsam los ntawm 20mil txheeb ze rau ntawm ntug ntawm lub rooj tsavxwm, es tsis txhob. nteg cov tawv tawv tag nrho rau ntawm ntug ntawm lub rooj tsavxwm.
Muaj ntau txoj hauv kev los ua qhov no, xws li kos cov txheej txheem khaws cia ntawm ntug ntawm lub rooj tsavxwm thiab teeb tsa qhov kev ncua deb. Ib txoj hauv kev yooj yim tau qhia ntawm no, uas yog, qhov sib txawv ntawm kev nyab xeeb yog teem rau cov khoom siv tooj liab. Piv txwv li, yog tias qhov kev nyab xeeb ntawm tag nrho cov phaj yog teem rau 10mil, thiab cov tooj liab tso rau 20mil, cov nyhuv ntawm shrinking 20mil hauv lub phaj ntug tuaj yeem ua tiav, thiab cov tooj liab tuag uas yuav tshwm sim hauv lub cuab yeej kuj tuaj yeem ua tau. tshem tawm.
