Daim ntawv thov
Ob tog ntawm lub rooj tsavxwm yog tsuas yog los daws cov kev tsim qauv hauv Circuit Court complex thiab cheeb tsam txwv, ntawm ob sab ntawm lub rooj tsavxwm tau teeb tsa cov khoom, ob txheej txheej lossis ntau txheej thaiv. , amplifiers, teeb pom kev zoo, thiab tsheb dashboards. Ob-sided PCBs yog qhov zoo tshaj plaws rau kev siv thev naus laus zis siab dua, cov khoom siv hluav taws xob sib txuas, thiab cov voj voog nyuaj. Nws daim ntawv thov yog dav heev thiab tus nqi qis.
FAQs
2-txheej PCB yog tooj liab coated ntawm ob sab nrog ib txheej insulating nyob rau hauv nruab nrab. Nws muaj cov khoom ntawm ob sab ntawm lub rooj tsavxwm, uas yog vim li cas nws tseem hu ua ob-sided PCB. Lawv yog fabricated los ntawm kev koom nrog ob txheej ntawm tooj liab ua ke, nrog ib tug dielectric khoom nyob rau hauv nruab nrab.
Koj tuaj yeem pom qhov txawv qhov txawv ntawm 2 txheej PCB thiab 4 txheej PCB raws li lawv cov npe. 2 txheej PCB muaj ob sab kab nrog rau sab saum toj thiab hauv qab txheej, thaum 4 txheej PCB muaj 4 txheej. Yog tias koj muaj kev nkag siab zoo ntawm ob hom PCB boards, koj yuav pom tias muaj ntau qhov sib txawv ntawm lawv tsim thiab yuav ua li cas.
Cov kab ib sab PCB tsuas muaj nyob rau ntawm ib sab xwb, thaum ob tog PCBs muaj cov kab ntawm ob sab nrog rau sab saum toj thiab hauv qab. Lub Cheebtsam thiab conductive tooj liab yog mounted rau ntawm ob sab ntawm ib tug ob-sided PCB, thiab qhov no ua rau kev sib tshuam los yog sib tshooj ntawm txoj kab.
Yog, cia li xa koj cov ntaub ntawv gerber rau peb.

Cov2 txheej PCB(ob-sided PCB) yog lub rooj tsav xwm luam tawm nrog tooj liab coated ntawm ob sab, sab saum toj thiab hauv qab. Muaj ib txheej txheej insulating nyob rau hauv nruab nrab, uas yog ib qho uas nquag siv luam tawm Circuit Board. Ob tog tuaj yeem ua qauv thiab soldered, uas zoo heev txo qhov nyuaj ntawm layout, yog li nws yog dav siv.
Txhawm rau siv cov khoom siv hluav taws xob ntawm ob sab, yuav tsum muaj kev sib txuas kom zoo ntawm ob sab. Cov "choj" ntawm cov circuits no hu ua vias. A via yog ib lub qhov me me ntawm lub rooj tsavxwm PCB tau ntim lossis coated nrog hlau, uas tuaj yeem txuas nrog lub voj voog ntawm ob sab. Vim hais tias thaj tsam ntawm lub rooj tsavxwm ob sab yog ob zaug loj dua li ntawm lub rooj tsavxwm ib leeg, lub rooj tsavxwm ob tog daws tau qhov nyuaj ntawm lub rooj tsavxwm ib leeg vim yog qhov sib txuam (nws tuaj yeem txuas nrog rau lwm sab. los ntawm lub qhov), thiab nws yog qhov tsim nyog rau kev sib tw ntau dua li ntawm lub rooj tsav xwm ib leeg.
Peb xav tau cov khoom siv hluav taws xob uas muaj kev ua haujlwm siab, me me, thiab ntau lub zog, uas txhawb kev tsim cov khoom siv hluav taws xob tsim hluav taws xob kom muaj lub teeb, nyias, luv, thiab me me. Nrog rau qhov chaw txwv, ntau lub zog tuaj yeem ua tiav, qhov txheej txheem ntom ntom tau ua ntau dua, thiab lub qhov taub me dua. Qhov tsawg kawg nkaus txoj kab uas hla ntawm txhua yam drilling peev xwm tau poob los ntawm 0.4mm mus rau 0.2mm los yog txawm me me. Lub qhov taub ntawm PTH tau txais me me thiab me. Qhov zoo ntawm PTH (Plated Through Hole) uas cov txheej txheem-rau-txheej interconnection yog ncaj qha ntsig txog qhov kev ntseeg siab ntawm cov ntawv luam tawm Circuit Board.
