Tsim cov neeg hlau nrog txhav PCB pawg thawj coj saib yam tsis xav txog kev tiv thaiv PCB los ntawm kev ua tsis tiav tshwm sim los ntawm kev siv tshuab sib nqus. Cov kev ua tsis tiav no tuaj yeem ua rau muaj teeb meem loj xws li cov insulators tawg thiab cov khoom siv hluav taws xob, cov khoom sib txuas tsis sib xws, PCB thaiv qhov txuas txuas tsis sib xws, cov kab laug sab tawg, PCB txheej txheej txheej, hluav taws xob luv luv thiab tshem tawm cov plating chim rau lub ncoo. Txhawm rau tshem tawm cov kev ua tsis tiav, yuav tsum tau hloov pauv cov khoom siv hluav taws xob sib dhos kom yooj yim.

Dab tsi yog txhav yooj ywm PCB?

A printed circuit board in which rigid and flexible circuit plates are laminated together to weld parts on rigid parts and bend parts instead of wired connections. Ib qho txhav tuaj yeem zoo li ib txwm PCB txhav, qhov uas cov khoom tuaj yeem txuas tau ntawm ob sab ntawm lub rooj tsavxwm thiab ntau txheej txheej sib txuas tuaj yeem ua tau, thaum qhov hloov pauv tau tuaj yeem txuas nrog ntau txheej, tab sis cov khoom tuaj yeem txuas rau ntawm nws vim tias qhov hloov pauv tau siv los txuas tsuas yog ntawm ntu ntu ntu nruj.

Tshem tawm cov khoom sib txuas los ntawm kev tsim qhia cov khoom hauv qab no rau hauv Circuit: Kev xa cov teeb liab los ntawm ib feem mus rau lwm yam yam tsis poob lossis tsis zoo (suab nrov) Tshem tawm cov teeb meem kev sib txuas xws li mob khaub thuas.Pub dawb qhov chaw thiab txo qhov hnyav. Ua rau kev tiv thaiv kev tiv thaiv Circuit Court thiab tuaj yeem teeb tsa hauv cov ntawv thov nrog cov khoom txav.

Tsim nruj PCB yooj ywm:

Muaj ntau yam software muaj rau tsim kom nruj ua tau yooj yim PCBS, tab sis Altium muab qhov pom tau zoo tshaj plaws 3D pom ntawm txhav yooj ywm PCBS thiab tau pom zoo. Thaum tsim cov ntu nruj thiab hloov pauv tau, nws yog qhov tseem ceeb tshaj plaws los xaiv qhov tooj liab taug qab dav raws li daim ntawv thov.

Qhov no qhia tias tib yam tam sim no yuav tsum tau siv hauv qhov txhav thiab nkhaus nrog cov kab sib txawv sib txawv vim qhov tuab, thaj tsam thiab kev tso cai ntawm cov khoom. Rayming PCB thiab Cov kws ua haujlwm sib dhos ib txwm muaj los tham txog qhov dav thaiv qhov raug thiab cov khoom siv zoo rau koj li kev siv zaus thiab daim ntawv thov.

Simulation ntawm PCB yooj ywm:

Daim ntawv menyuam roj hmab tsab ntawv tseem ceeb heev hauv kev tsim cov khoom hloov pauv tau yooj yim. Qhov kev coj ua yooj yim no tuaj yeem pab cov tsim qauv tiv thaiv ntau qhov yuam kev los ntawm kev qhia teeb meem cuam tshuam nrog khoov thaum ntxov, thiab tuaj yeem txuag sijhawm thiab nyiaj txiag. Qhov no pab tus tsim qauv kwv yees qhov khoov lub vojvoog thiab xaiv txoj hauv kev rau txoj kab tooj liab txhawm rau tiv thaiv kom los kua muag lossis tsis sib xws.

Tsim tooj liab kab nrog kev tsis ncaj ncees:

Ua kom muaj tooj liab ntxiv hauv kev tsim ua kom muaj kev ruaj ntseg ntawm qhov hloov pauv tau yooj yim. Rau ib leeg-txheej thiab ob tog ua qauv tsim tau yooj yim, ua rau ib puag ncig cov tooj liab yog qhov kev coj ua zoo. Kev ntxiv lossis tshem tawm cov tooj liab ntxiv tsuas yog nyob ntawm daim ntawv thov, tab sis yog tias tus tsim qauv muaj tooj liab ntxiv nrog kev tsis ncaj ncees, cov cim nrog kev tsis ncaj ncees yuav tsum yog siv rau kev ruaj ntseg zoo. Ib qho ntxiv, ua li ntawd tuaj yeem txo tus nqi tooj liab, uas yog tus phooj ywg ib puag ncig hais txog kev siv tshuaj lom neeg.

Txhim kho tus qauv hauv ntau txheej yooj:

Staggered tsim ntev feem ntau yog siv los pab tsim cov txheej txheem hloov pauv tau yooj yim. Hauv cov txheej txheem no, tus tsim qauv nce me ntsis qhov ntev ntawm txhua txheej hloov pauv tom ntej, uas feem ntau yog 1.5 npaug ntawm cov tuab ntawm tus kheej txheej. Qhov no tiv thaiv qhov chaw khoov ntawm txheej txheej nkhaus hauv ntau txheej txheej hloov pauv tau nrog txheej cais. Los ntawm txoj hauv kev yooj yim no, lub zog tensor thiab i-beam cov txiaj ntsig tau tsim los ntawm txheej txheej txheej hlau tuaj yeem raug tshem tawm, uas tej zaum yuav yog qhov teeb meem tseem ceeb hauv kev thov hloov pauv.

Taug qab txoj hlua thaiv:

Qee qhov teeb meem cuam tshuam nrog kev txuas xov hlau hauv kev hloov pauv yooj yim suav nrog khaws tus lej hla mus rau qhov tsawg kawg yog li cov txheej txheem tuaj yeem txo kom txuag tau nyiaj, thiab qhov thib ob yog khoov lub kaum sab xis ntawm cov kab hauv kev hloov pauv tau yooj yim. Cov kab yuav tsum tau khoov thiab khoov ib ncig ntawm cov ces kaum, vim cov ces kaum ntse tuaj yeem cuab kev daws thaum lub sij hawm etching thiab tej zaum yuav dhau mus thiab yuav nyuaj rau ntxuav tom qab kho tas. Thaum muaj cov cim tooj liab ntawm ob sab ntawm kev hloov pauv tau yooj yim, tus tsim qauv yuav tsum tsim qhov chaw ntawm 2-2.5 npaug ntawm kab dav kom tsis txhob muaj hluav taws xob luv luv thiab tsim nyog kos. Xav txog cov lus txib no tuaj yeem txhim kho teeb liab nthuav tawm thiab txo kev xav thaum lub sijhawm tig.

Rigid dabtsi yog khoov hloov ntu:

Qhov tsawg kawg nkaus nrug ntawm qhov nruj mus rau thaj tsam hloov pauv hloov mus rau ntug ntawm qhov kev tshem tawm thiab qhov plated los ntawm qhov yuav tsum tsis pub tsawg dua 0.0748 ntiv tes. Thaum tsim qhov kev ncua deb ntawm qhov tsis plated los ntawm lub qhov thiab sab hauv thiab sab ntug ntawm qhov txiav, cov khoom siv zaum kawg yuav tsum tsis pub tsawg dua 0.0197 ntiv tes.

Rigid – yooj ywm interface txheej los ntawm lub qhov:

Qhov kev pom zoo tsawg kawg ntawm qhov hla ntu ntu thiab plated los ntawm qhov ntawm cov tawv tawv hloov pauv tau yooj yim dua 0.125 nyob rau hauv. Kev ua txhaum txoj cai no yuav cuam tshuam rau kev ntseeg tau ntawm plating los ntawm lub qhov.
