PCB circuit boards yog dav siv nyob rau hauv ntau yam khoom siv hluav taws xob nyob rau hauv niaj hnub industrially tsim ntiaj teb no.Raws li kev lag luam sib txawv, cov xim, cov duab, qhov loj me, txheej, thiab cov khoom siv ntawm PCB Circuit Board yog txawv.Yog li ntawd, cov ntaub ntawv meej yog xav tau hauv kev tsim ntawm PCB Circuit Board, txwv tsis pub kev nkag siab yuam kev yuav tshwm sim.Kab lus no qhia txog kaum qhov tsis xws luag raws li cov teeb meem hauv cov txheej txheem tsim ntawm PCB Circuit Boards.
1. Lub ntsiab lus ntawm kev ua theem tsis meej
Lub rooj tsav xwm ib leeg yog tsim los ntawm TOP txheej.Yog tias tsis muaj kev qhia ua rau pem hauv ntej thiab nraub qaum, nws yuav nyuaj rau solder lub rooj tsavxwm nrog cov khoom siv ntawm nws.
2. Qhov kev ncua deb ntawm thaj tsam loj ntawm cov ntawv ci tooj liab thiab cov thav duab sab nrauv yog ze heev
Qhov kev ncua deb ntawm thaj tsam loj ntawm cov ntawv ci tooj liab thiab cov thav duab sab nrauv yuav tsum yog tsawg kawg 0.2 hli, vim hais tias thaum milling cov duab, yog tias nws yog milled rau ntawm cov ntawv ci tooj liab, nws yooj yim ua rau cov ntawv ci tooj liab ua rau muaj kev kub ntxhov thiab ua rau cov hlau tsis kam. kom poob.
3. Siv cov ntaub thaiv npog los kos cov ntaub qhwv
Kev kos cov ntaub qhwv nrog cov blocks tuaj yeem dhau DRC kev tshuaj xyuas thaum tsim cov circuits, tab sis tsis yog rau kev ua haujlwm.Yog li ntawd, cov ntaub qhwv no tsis tuaj yeem tsim cov ntaub ntawv npog ntsej muag ncaj qha.Thaum solder tiv thaiv yog thov, thaj tsam ntawm qhov muab tub lim yuav raug them los ntawm solder resist, ua rau cov cuab yeej vuam nyuaj.
4. Cov txheej hauv av hluav taws xob yog lub paj paj thiab kev sib txuas
Vim hais tias nws yog tsim los ua ib lub hwj chim mov nyob rau hauv daim ntawv ntawm pads, lub hauv av txheej yog opposite rau cov duab ntawm lub board luam ntawv tiag tiag, thiab tag nrho cov kev sib txuas yog cais kab.Ceev faj thaum kos ob peb lub zog hluav taws xob lossis ntau cov kab hauv av cais tawm, thiab tsis txhob tawm qhov khoob kom ua rau ob pawg Ib qho luv luv ntawm cov khoom siv hluav taws xob tsis tuaj yeem ua rau thaj chaw sib txuas.
5. Cov cim tsis raug
SMD pads ntawm cov cim npog cov ntaub qhwv ua rau tsis yooj yim rau qhov kev xeem ntawm cov ntawv luam tawm thiab cov khoom siv vuam.Yog tias tus cwj pwm tsim me dhau lawm, nws yuav ua rau kev tshuaj ntsuam luam ntawv nyuaj, thiab yog tias nws loj dhau, cov cim yuav sib tshooj, ua rau nws nyuaj rau qhov txawv.
6.surface mount device pads luv dhau
Qhov no yog rau kev sim tawm.Rau cov khoom siv ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom cov khoom siv, qhov kev ncua deb ntawm ob tus pins yog qhov me me, thiab cov ntaub qhwv kuj tseem nyias heev.Thaum txhim kho cov pins xeem, lawv yuav tsum tau staggered nce thiab nqis.Yog hais tias lub ncoo tsim luv luv, txawm hais tias nws tsis yog Nws yuav cuam tshuam rau kev teeb tsa ntawm lub cuab yeej, tab sis nws yuav ua rau cov pins xeem tsis sib cais.
7. Ib leeg-sab ncoo aperture teeb
Ib leeg-sided pads feem ntau tsis drilled.Yog hais tias lub qhov drilled yuav tsum tau cim, lub aperture yuav tsum tau tsim raws li xoom.Yog tias tus nqi tsim, ces thaum cov ntaub ntawv drilling yog tsim, lub qhov sib koom tes yuav tshwm sim ntawm txoj haujlwm no, thiab teeb meem yuav tshwm sim.Ib leeg-sided pads xws li drilled qhov yuav tsum tau cim tshwj xeeb.
8. Pauv sib tshooj
Thaum lub sij hawm drilling txheej txheem, lub laum me ntsis yuav tawg vim muaj ntau yam drilling nyob rau hauv ib qho chaw, ua rau lub qhov puas.Ob lub qhov nyob rau hauv cov txheej txheem ntau txheej sib tshooj, thiab tom qab qhov tsis zoo yog kos, nws yuav tshwm sim raws li cov phaj cais, ua rau cov khoom seem.
9. Muaj ntau qhov txhaws hauv cov qauv tsim lossis cov khoom ntim puv puv nrog cov kab nyias nyias
Cov ntaub ntawv photoplotting ploj, thiab cov ntaub ntawv photoplotting tsis tiav.Vim hais tias lub filling block yog kos ib los ntawm ib tug nyob rau hauv lub teeb teeb duab cov ntaub ntawv ua, yog li tus nqi ntawm lub teeb duab cov ntaub ntawv generated yog heev loj, uas ua rau kom cov ntaub ntawv nyuaj ua.
10. Kev tsim txom txheej txheej
Qee qhov kev sib txuas tsis muaj txiaj ntsig tau ua rau qee cov txheej txheem duab.Nws yog Ameslikas plaub-txheej board tab sis ntau tshaj tsib txheej ntawm circuits tau tsim, uas ua rau muaj kev nkag siab yuam kev.Ua txhaum ntawm cov qauv tsim.Cov txheej txheem duab yuav tsum khaws cia kom zoo thiab meej thaum tsim.
