SMT || Cov lus qhia kom zoo kawg nkaus architecting PCB tshwj xeeb Cheebtsam

Nyob rau ntawm lub rooj tsavxwm PCB, peb feem ntau siv cov khoom tseem ceeb uas nquag siv, cov khoom tseem ceeb hauv Circuit Court, yooj yim cuam tshuam cov Cheebtsam, high voltage Cheebtsam, siab calorific nqi Cheebtsam thiab ib co heterosexual Cheebtsam hu ua tshwj xeeb Cheebtsam. Kev mus ntsib layout ntawm cov khoom tshwj xeeb no yuav tsum tau ua tib zoo tshuaj xyuas. Vim tias qhov chaw tsis raug ntawm cov khoom tshwj xeeb no tuaj yeem ua rau kev sib raug zoo hauv Circuit Court tsis raug thiab teeb liab tsis ncaj ncees lawm, ua rau tag nrho PCB Circuit Board tsis tuaj yeem ua haujlwm.

Thaum tsim yuav ua li cas tso qhov tshwj xeeb, ua ntej xav txog qhov loj ntawm PCB. Thaum lub PCB loj dhau lawm, cov kab luam ntawv ntev dhau lawm, qhov impedance yog nce, qhov qhuav kuj raug txo, thiab tus nqi nce ntxiv. Yog tias nws tsawg dhau, qhov cua sov dissipation tsis zoo, thiab cov kab uas nyob ib sab tuaj yeem raug cuam tshuam.

Tom qab txiav txim siab PCB loj, txiav txim siab txoj haujlwm square ntawm cov khoom tshwj xeeb. Thaum kawg, tag nrho cov khoom ntawm lub Circuit Court yog teem raws li lub functional unit. Txoj hauj lwm ntawm qhov tshwj xeeb feem ntau yuav tsum ua raws li cov hauv qab no thaum npaj:

Qhov tshwj xeeb layout txoj cai

1. Txo qhov kev sib txuas ntawm cov khoom siv hluav taws xob ntau kom ntau li ntau tau kom txo tau lawv cov kev faib tawm thiab kev cuam tshuam hluav taws xob ntawm ib leeg. Cov khoom raug cuam tshuam yuav tsum tsis txhob sib ze heev, thiab cov khoom siv thiab cov khoom tawm yuav tsum sib nrug deb li qhov ua tau.

(2) Qee cov khoom siv lossis cov xov hlau yuav muaj qhov sib txawv siab, yog li qhov kev ncua deb ntawm lawv yuav tsum tau nce ntxiv kom tsis txhob muaj kev sib tsoo luv luv los ntawm kev tso tawm. Cov khoom siv hluav taws xob siab yuav tsum tau muab tso kom deb li deb li deb tau ntawm tes.

3. Cov khoom uas hnyav tshaj 15g tuaj yeem kho nrog lub bracket thiab ces welded. Cov khoom hnyav thiab kub no yuav tsum tsis txhob muab tso rau ntawm lub rooj tsav xwm hauv Circuit Court, tab sis yuav tsum tau muab tso rau hauv lub thawv loj hauv qab phaj, thiab yuav tsum xav txog qhov kub dissipation. Khaws cov khoom kub kom deb ntawm qhov kub.

4. Rau qhov layout ntawm adjustable Cheebtsam xws li potentiometers, adjustable inductors, kuj tsis paub meej capacitors thiab microswitches, cov txheej txheem ntawm tag nrho cov board yuav tsum tau xav txog. Yog tias tus qauv tso cai, qee qhov kev siv cov keyboards feem ntau yuav tsum tau muab tso rau hauv ib txoj hauj lwm yooj yim rau tes. Lub layout ntawm cov khoom yuav tsum sib npaug, ntom, thiab tsis hnyav tshaj qhov saum toj.

Kev vam meej ntawm ib yam khoom, ib qho yog ua tib zoo mloog rau sab hauv zoo. Tab sis xav txog tag nrho cov kev zoo nkauj, ob qho tib si yog cov zoo meej PCB boards thiaj li yuav ua tau zoo cov khoom.
