PCB engineers feem ntau ntsib ntau yam teeb meem kev nyab xeeb thaum ua PCB tsim. Feem ntau cov kev sib txawv no tau muab faib ua ob pawg, ib qho yog hluav taws xob kev nyab xeeb kev nyab xeeb, thiab lwm qhov yog kev nyab xeeb tsis muaj hluav taws xob. Yog li, dab tsi yog qhov yuav tsum tau sib nrug ntawm kev tsim PCB Circuit Board?

1. Kev nyab xeeb ntawm hluav taws xob

1. Qhov sib nrug ntawm cov xov hlau: qhov tsawg kawg ntawm kab sib nrug kuj yog kab-rau-kab, thiab kab-rau-pad qhov sib nrug yuav tsum tsis pub tsawg dua 4MIL. Los ntawm qhov kev xav ntau lawm, tau kawg, qhov loj dua qhov zoo dua yog tias ua tau. Cov pa 10MIL ntau dua.

2. Pad aperture thiab ncoo dav: Raws li PCB chaw tsim tshuaj paus, yog hais tias lub ncoo aperture yog mechanically drilled, qhov tsawg kawg nkaus yuav tsum tsis txhob tsawg tshaj li 0.2 hli; yog siv laser drilling, qhov tsawg kawg nkaus yuav tsum tsis pub tsawg tshaj 4mil. Lub aperture kam rau ua yog txawv me ntsis nyob ntawm lub phaj, feem ntau tuaj yeem tswj tau hauv 0.05mm; qhov tsawg kawg nkaus qhov dav ntawm thaj av yuav tsum tsis pub tsawg tshaj 0.2 hli.

3. Qhov kev ncua deb ntawm lub ncoo thiab lub ncoo: Raws li kev ua haujlwm ntawm PCB cov chaw tsim khoom, qhov kev ncua deb yuav tsum tsis pub tsawg dua 0.2MM.

4. Qhov kev ncua deb ntawm daim ntawv tooj liab thiab lub board ntug: nyiam dua tsis pub tsawg dua 0.3mm. Yog tias nws yog thaj chaw loj ntawm tooj liab, feem ntau yog qhov kev ncua deb ntawm ntug ntawm lub rooj tsavxwm, feem ntau teem rau 20mil.

2. Tsis muaj hluav taws xob kev nyab xeeb nyob deb

1. Qhov dav, qhov siab thiab qhov sib txawv ntawm cov cim: Cov cim ntawm silk screen feem ntau siv cov txiaj ntsig zoo xws li 5/30, 6/36 MIL, thiab lwm yam. Vim tias thaum cov ntawv nyeem me dhau, cov txheej txheem luam ntawv yuav plooj.

2. Qhov kev ncua deb ntawm lub vijtsam txhob lo lo ntxhuav mus rau lub ncoo: lub tshuab luam ntawv txhob lo lo ntxhuav tsis pub rau ntawm lub ncoo. Vim hais tias yog cov tshuaj ntsuam txhob lo lo ntxhuav yog npog nrog lub ncoo, lub ntsej muag txhob lo lo ntxhuav yuav tsis tinned thaum nws yog tinned, uas yuav cuam tshuam rau qhov kev tso kawm. Nws yog feem ntau yuav tsum tau tseg 8mil nrug. Yog tias thaj tsam ntawm qee qhov PCB boards ze heev, 4MIL qhov sib txawv kuj tau txais. Yog tias lub vijtsam txhob lo lo ntxhuav npog lub ncoo thaum tsim, ib feem ntawm lub vijtsam txhob lo lo ntxhuav sab laug ntawm lub ncoo yuav raug tshem tawm thaum lub sijhawm tsim khoom los xyuas kom meej tias lub ncoo yog tinned.

3. 3D qhov siab thiab kab rov tav qhov sib txawv ntawm cov qauv siv tshuab: Thaum mounting Cheebtsam ntawm PCB, xav txog seb qhov kev taw qhia kab rov tav thiab qhov chaw siab yuav cuam tshuam nrog lwm cov qauv siv tshuab. Yog li ntawd, thaum tsim, nws yog tsim nyog los xav txog tag nrho cov adaptability ntawm qhov chaw qauv ntawm lub Cheebtsam, thiab nruab nrab ntawm lub tiav lawm PCB thiab cov khoom plhaub, thiab tseg ib tug zoo nyob deb ntawm txhua lub hom phiaj.

Cov saum toj no yog qee qhov kev ncua deb uas yuav tsum tau ua kom tau raws li thaum tsim PCB Circuit Board. Koj puas paub txhua yam?
