Kev Nyab Xeeb Hluav Taws Xob
1. Sib txuam ntawm cov xov hlau
Raws li kev tsim khoom ntawm pcb cov tuam ntxhab, qhov deb ntawm cov kab thiab cov kab yuav tsum tsis pub tsawg tshaj 4 lab. Qhov tsawg kawg ntawm kab kab yog tseem yog kab-rau-kab thiab kab-rau-ncoo spacting. Zoo, los ntawm peb cov khoom ntau lawm ntawm kev pom, ntawm chav kawm, qhov loj dua nyob hauv cov xwm txheej. Qhov dav dav 10 lab muaj ntau dua.
2. Ncoo aperture thiab ncoo dav:
Raws li PCB cov chaw tsim tshuaj paus, qhov tsawg kawg ntawm txoj kab uas hla ntawm lub ncoo tsis pub tsawg dua 0.2 mm yog tias nws yog qhov tsis tshua muaj neeg kho tshuab drilling, thiab nws tsis yog tsawg tshaj 4 lab yog tias nws yog laser dreded. Lub apertate kam muaj dua me ntsis sib txawv nyob ntawm lub phaj. Feem ntau nws tuaj yeem tswj tsis pub dhau 0.05 hli. Qhov tsawg kawg ntawm lub ncoo yuav tsum tsis pub tsawg tshaj 0.2 hli.
3. Qhov kev ncua deb ntawm cov ntaub qhwv thiab ntaub qhwv:
Raws li cov peev txheej ntawm PCB cov tuam txhab, qhov kev ncua deb ntawm cov ntaub qhwv thiab cov ntaub qhwv yuav tsum tsis txhob tsawg dua 0.2 hli.
4. Qhov kev ncua deb ntawm cov tawv nqaij tooj liab thiab ntug ntawm lub rooj tsavxwm:
Qhov kev ncua deb ntawm cov tawv nqaij tooj liab thiab ntug ntawm PCB Board yog qhov dua tsis tsawg tshaj li 0.3 hli. Yog tias tooj tooj tooj liab nyob rau thaj chaw loj, feem ntau nws yog feem ntau yuav tsum muaj qhov txaus ntshai los ntawm ntug ntawm lub rooj tsavxwm, uas feem ntau tau teem rau 20 lab. Feem ntau, vim kev txiav txim siab kho tshuab ntawm cov kab ke Circuit Court, lossis kom tsis txhob muaj tooj liab sawb ntawm ntug kev lossis hluav taws xob luv nqi tooj liab los ntawm 20 lab txheeb ze rau ntawm ntug ntawm lub rooj tsavxwm. Cov tawv nqaij tooj liab tsis yog ib txwm kis mus rau ntug ntawm lub rooj tsavxwm. Muaj ntau txoj hauv kev los daws qhov no tooj liab shrinkage. Piv txwv li, kos cov txheej kom ua kom pom ntawm ntug ntawm lub rooj tsavxwm, thiab tom qab ntawd teeb qhov kev ncua deb ntawm tooj liab thiab kom ua kom ruaj.
Tsis-Hluav Taws Xob Kev Nyab Xeeb
1. Tus cwj pwm dav thiab qhov siab thiab txuas:
Hais txog cov cim ntawm cov vijtsam lo lo ntxhuav
2. Qhov kev ncua deb los ntawm cov kab mob silk hauv ncoo:
Tshuaj ntsuam luam ntawv tsis pub cov ntaub qhwv. Yog hais tias lub vijtsam lo lo ntxhuav yog npog nrog cov ntaub qhwv, cov tin yuav tsis tanned thaum soldering, uas yuav cuam tshuam rau kev tso chaw ntawm cov khoom siv. Cov tuam txhab tuam txhab tswj hwm dav dav yuav tsum muaj 8 mil uas yuav tsum tau tshwj tseg. Yog tias nws yog vim thaj tsam ntawm qee lub pcb cov laug cam yog qhov sib ze heev, qhov kev sib tw ntawm 4mil yog NW nyuam qhuav siv tau. Tom qab ntawd, yog hais tias lub vijtsam lo lo ntxhuav tau npog lub ncoo thaum lub chaw tsim khoom lag luam yuav txiav tawm cov kab ntawv lo lo ntxhuav sab laug thaum tsim khoom kom ntseeg tau tias cov phuam. Yog li peb yuav tsum tau them sai sai.
3. 3D qhov siab thiab kab rov tav txuas ntawm cov qauv khoom siv:
Thaum mounting cov khoom siv ntawm PCB, nws yog qhov tsim nyog los txiav txim siab seb cov kab rov tav thiab qhov chaw kab rov tav yuav tsis sib haum nrog lwm cov neeg kho tshuab. Yog li ntawd, thaum tsim qauv, nws yog ib qho tsim nyog los xav txog kev yoog raws li cov khoom siv PCB thiab cov khoom lag luam muag khoom, thiab tsuas yog nyob deb deb rau txhua lub hom phiaj.
