PCB pawg thawj coj saib kev tsim cov ntsiab lus:

Ua kom tiav kev sib txuas sib txuas hluav taws xob cov qauv luam tawm Circuit Board lossis PCB. Nws muaj ib qho thiab ntau yam kev ua haujlwm zoo. Cov phiajcim no ua tau raws li qhov xav tau ntawm cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob. Lub Rooj Tswjhwm Saib PCB muaj cov khoom siv rwb thaiv tsev uas txheej txheej txheej ntawm cov khoom siv tau teeb tsa. Cov khoom siv hluav taws xob tshwj xeeb tau muab tso rau ntawm cov khoom siv hluav taws xob (substrate) ntawm PCB thiab txuas nrog kev sib txuas hauv Circuit Court los ntawm kev sov thiab nplaum. Lawv kuj tseem tuaj yeem siv ua raws cov hloov pauv tau.

Cov neeg tsim khoom yuav tsum nthuav tawm ib qho tsis raug qhov tsis raug hauv txoj kev npaj. Txawm li cas los xij, qhov kev hloov pauv tau nce zuj zus raws li ntau lub koom haum outsource lawv cov PCB kev thov rau cov kws muab khoom txawv teb chaws.

PCB tsim kev poob rau hauv peb yam tseem ceeb:

Ib leeg ib leeg: Cov PCBS no muaj cov txheej txheej ua kom sov thiab txheej txheej tooj liab laminated rwb thaiv tsev cov lus. Cov khoom siv hluav taws xob tau txuas nrog ib sab ntawm lub substrate.

Ob tog ob tog: Hauv PCB no, cov khoom siv ntau dua yuav raug teeb tsa ntawm cov txheej txheem dua li ntawm ib sab PCB.

Multilayer: Cheebtsam ntawm lub substrate txuas nrog los ntawm kev nqes mus rau hauv cov qhov hluav taws xob hauv cov txheej txheem tsim nyog. Tus naj npawb ntawm ntau lub PCBS teeb tsa tshaj ib leeg-sab thiab ob tog PCBS. Nws ua rau tus qauv ntawm Circuit Court yooj yim dua.

Kuj tseem muaj ob hom: kev sib xyaw ua ke (tseem hu ua ics lossis microchips) thiab kev sib txuas sib txuas. IC txoj hauv kev zoo ib yam li lwm hom, tab sis muaj ntau lub voj voos txuas rau saum npoo ntawm cov pob zeb me me silicon. Tsuas yog qhov sib txawv hauv cov hluav taws xob sib txuas yog tias cov khoom siv tau cog rau ntawm qhov chaw ntau dua li tso nrog nplaum.

cheebtsam:

Ntawm PCB pawg thawj coj, cov khoom siv hluav taws xob tau teeb tsa saum npoo. Kuj tseem muaj ntau yam txheej txheem, xws li:

Los ntawm kev siv tshuab:

Tau ntau xyoo, thev naus laus zis dhau los tau siv los tsim yuav luag txhua daim ntawv luam tawm Circuit Board (PCBS). Qhov dhau los ntawm qhov tau teeb tsa los ntawm ob txoj hauv kev ua haujlwm. Txog cov khoom siv dag zog, cov hlau lead tau khoov ntawm 90 degree Lub kaum ntse ntse thiab muag hauv qhov rov qab. Kev hla-qhov kev txhim kho yog qhov ntseeg tau zoo vim nws muab kev sib txuas zoo nrog cov neeg kho tshuab; Txawm li cas los xij, qhov kev khawb av ntxiv ua rau cov laug cam kim dua los tsim.

Kev siv tshuab nto:

SMT tsawg dua nws qhov sib koom ua ke. Qhov no yog vim tias SMT qhov tseem ceeb muaj cov coj me lossis tsis muaj tus coj txhua. Nws yog ib lub hlis twg rau ib feem peb dhau los ntawm qhov. PCBS nrog cov cuab yeej siv sab saum toj (SMD) tsis xav tau ntau qhov kev khawb, thiab cov yam tseem ceeb no yog qhov nqaim heev, tso cai rau kom muaj hluav taws xob ntau dua ntawm cov laug cam.

Los ntawm qhov ua tau zoo ntawm kev siv tshuab, cov nqi zog raug txo thiab tsim khoom tau zoo dua qub.

tsim:

Cov tuam txhab tsim khoom lag luam PCB siv lub khoos phis tawj pab daws teeb meem (CAD) los tsim cov qauv kev sib tw ntawm lub rooj tsavxwm. Cov haujlwm tshwj xeeb tau muab rau cov khoom tshwj xeeb. Pawg thawj coj yuav tsum ua tiav txoj haujlwm, uas nws tau xaiv. Qhov chaw nruab nrab ntawm txoj kab hluav taws xob thiab txoj kev coj ua yog nqaim. Feem ntau nws yog 0.04 ntiv tes (1.0 hli) lossis tsawg dua.

Nws tseem yuav tso tawm cov khoom txhuas lossis kov qhov ze ze ntawm lub qhov, thiab cov ntaub ntawv no yuav hloov pauv mus rau hauv cov lus qhia rau CNC drilling lub laptop lossis kev siv tshuab siv hauv kev siv lub tshuab tsis siv neeg txuas.

Luam daim duab lossis daim npog ntsej muag kom raug rau qhov loj me ntawm daim ntawv yas huv, piv txwv li tam sim ntawd tom qab pom cov qauv hauv Circuit Court. Yog tias daim duab tsis zoo, thaj chaw uas tsis tuaj yeem yog ib qho piv txwv ntawm cov khoom siv hluav taws xob yuav raug tsim ua xim dub thiab cov qauv hauv Circuit Court yuav raug kuaj kom pom tseeb.
