Cov raj xa hluav taws xob yog cov kauj ruam tseem ceeb hauv kev txhim kho cov khoom siv hluav taws xob. Hauv ntau qhov chaw lawv dhau los ua qhov qub dhau los hauv kev sib piv rau qhov pheej yig dua, me dua thiab muaj txiaj ntsig zoo dua hauv xeev cov thev naus laus zis. Nrog kev zam ntawm lub suab - ob qho kev luam tawm thiab nyob. Cov kab hluav taws xob hauv raj tau yooj yim thiab feem ntau cov khoom siv ua haujlwm tau txuas nrog ua lub raj tshuab raj lawv yog qhov zoo tshaj plaws rau kev tsim tus kheej - DIY. Lawv muaj tseeb txuas nrog qhov hluav taws xob siab thiab yog li tuaj yeem ua rau muaj kev phom sij, tab sis yog tias qee qhov kev qhia yooj yim tau ua raws, feem ntau ntawm qhov txaus ntshai tuaj yeem zam tau.

Thawj txoj hauv kev rau lub tsev tsim hluav taws xob tau hu ua point-to point, qhov twg cov khoom siv tau ncaj qha kho rau lub qhov (socket), lub lauj kaub, lub tsho.. nrog kev pab los ntawm ntau lub dav hlau. Txhawm rau pab txhawb kev tsim khoom ntau ces cov tuam txhab tau pib tso cov ntsiab lus ntawm cov laug cam sib txawv (qee txoj hauv kev tseem ua rau lub ntsiab lus-rau taw tes, txawm hais tias tsis yog qhov zoo li ntawd). Tam sim no feem ntau ntawm cov khoom siv hluav taws xob tau tsim los ua PCBs - luam tawm cov laug cam. Txawm tias feem ntau ntawm cov qauv tsim cov raj tsim los ntawm PCBs niaj hnub no. Tab sis PCBs muaj qee qhov tsis zoo rau lub ntiaj teb raj: - cov raj tsim hluav taws xob ntau thaum nyob, yog li txawm tias ua haujlwm tau zoo lawv pheej txo qis kev ua neej nyob ntawm PCB- feem ntau cov raj siv hluav taws xob tau yooj yim thiab ncaj, thiab siv (siab qhov hluav taws xob) cov ntsiab lus loj heev uas nws tsis nkag siab los tsim cov raj xa hluav taws xob ntawm tag nrho cov laug cam - yuav muaj feem ntau qhov chaw khoob thiab ob peb kab me me nrog qee cov pawm - tiag tiag pov tseg ntawm FR4 cov khoom - ntau qhov sib xyaw ntawm cov raj raj hnyav heev lossis hnyav heev yuav tsum tau teeb tsa ncaj qha mus rau PCB (hloov pauv, txhaws), lwm tus tsis tsim nyog rau PCB vim yog kev ua haujlwm nyuaj (lub raj uas lub qhov (socket) tau teeb tsa ncaj qha mus rau PCB yuav tsum tau pauv nrog kev saib xyuas)

Ntawm qhov tod tes nws qee zaum nyuaj rau txuas ncaj qha mus rau qhov chaw amp, thiab qee qhov yuav ua rau puas hauv cov txheej txheem (Kuv tau ua tiav hauv kev rhuav tshem ntau pawg ntawm cov hloov pauv thaum siv lawv). Nws kuj tseem nyuaj rau teeb meem thiab kev pabcuam classicaly point-to-point built devices, txawm tias ntau dua yog tias lawv tsis tau tsim nrog kev npaj zoo heev. PCB muab txoj hauv kev ruaj khov thiab los ntawm lub chassis-tshem tawm ntawm kev kho cov ntsiab lus.

Yog li qhov xwm txheej hu rau ib txoj hauv kev ntawm ib nrab taw tes rau taw tes txuas, zoo ib yam li lawv tau ua hauv kev paub ntaus suab paj nruag amps zoo li Marshall lossis Fender. Ntau tus neeg tsim khoom tseem siv lawv txoj hauv kev nrog cov txiaj ntsig zoo. Tab sis Fender - Marshall mus kom ze muaj qee qhov tsis zoo:

- lawv feem ntau siv cov khoom siv axial, uas tsis tshua muaj thiab tsis tshua muaj nqis- feem ntau ntawm cov khoom siv hauv Circuit yog paralelled, uas ua rau qhov chaw pov tseg thiab tuaj yeem ua rau muaj suab nrov, oscillations thiab kev sib koom ua ke- muaj qhov pom tshwm sim ntev ntawm cov laug cam- qhov no lub rooj tsavxwm feem ntau tau teeb tsa nyob rau hauv nruab nrab ntawm lub chassis, thawb tag nrho cov raj tso rau hauv nws, uas yog rov qis dua

Kev tsim qauv yooj yim thiab zoo ib yam ntawm feem ntau hi-fi thiab kev sib tw guitar ua rau peb siv txoj hauv kev hloov pauv hauv lub raj amp tsev, siv PCB cov qauv. Kev kawm cov txuj ci pab peb tsim PCBs, qhov twg tsis muaj qhov chaw pov tseg nrog cov ntsiab lus paralelled, tab sis ua raws li cov cai ntawm kev taug kab. Kev tsim ob tog ua rau peb ua cov qauv me dua thiab siv ob sab ntawm pawg thawj coj saib. Peb tuaj yeem txuas cov kab txuas rau PCBs, uas ua rau nws yooj yim dua los daws teeb meem thiab pabcuam cov khoom siv.

Rau DIYer nws tsis muaj txiaj ntsig los tsim PCB rau txhua qhov haujlwm, nws yuav kim heev! Tab sis kev yooj yim thiab zoo sib xws ntawm cov raj tsim tsim ua rau peb tias peb tsim PCBs, uas yog siv rau feem ntau ntawm cov ntawv thov.

Nov yog "sau" ntawm qee cov PCBs uas kuv tsim los pab txhawb raj raj ua.
