Kodi Mitundu Yosiyanasiyana ya Ma PCB Ndi Chiyani?
Ma PCB alipo m'njira zosiyanasiyana kuti agwiritsidwe ntchito mosiyanasiyana. Kusankha kapangidwe koyenera ka chinthu kumafuna injiniya kuti aganizire momwe chipangizocho chikugwiritsidwira ntchito, kukula kwake ndi mphamvu zake. Unikani zotsatirazi kuti mumvetse mitundu ya ma circuit board osindikizidwa komanso mitundu yomwe ili yoyenera ntchito zanu:
Ma PCB a mbali imodzi: Kupanga ma PCB kumaphatikizapo kupanga bolodi la circuit kuchokera ku gawo limodzi la substrate ndi gawo lochepa la chitsulo. Zigawo zonse zimasokedwa mbali imodzi.
Ma PCB Ambali Zonse: Mtundu wa PCB komwe mapepala achitsulo oyendetsera magetsi amayikidwa mbali zonse ziwiri za substrate.
Mabowo akhoza kubooledwa pakati pa bolodi lamagetsi kuti maulumikizidwe aziyenda mbali zonse ziwiri.
Ma PCB Okhala ndi Zigawo Zambiri: Ma PCB osachepera atatu okhala ndi zigawo ziwiri omwe amaikidwa pamwamba pa wina ndi mnzake ndi zigawo zingapo zotetezera kutentha kuti achepetse kutentha. Ma glue apadera omatira amasunga ma PCB angapo pamodzi.
Ma PCB Osinthasintha: Ma board osindikizidwa owonetsa zinthu zosinthasintha kuti athandize mainjiniya kuti azizolowera mawonekedwe azinthu zazing'ono. Ukadaulowu ukhoza kukhalapo mu mawonekedwe a zomangira za mbali imodzi, ziwiri kapena zambiri.
Ma PCB Olimba: Ndi othandiza pa zinthu zomwe anthu amagwiritsa ntchito zomwe zimakhala ndi mawonekedwe ofanana nthawi yonse ya moyo wawo. Ma PCB olimba amapangidwa pogwiritsa ntchito zinthu zolimba zomwe sizimapindika.
Ma PCB Olimba: Ma board a circuit osindikizidwa pogwiritsa ntchito zinthu zolimba komanso zosinthasintha. Makonzedwe awa amalola opanga zinthu kusunga malo, chifukwa njira zolumikizira zolimba komanso zosinthasintha zitha kuphatikizidwa pa board ya circuit yomweyo.
Ma PCB Othandizidwa ndi Aluminiyamu: Mtundu wa PCB womwe umalowa m'malo mwa chinthu chopangidwa ndi aluminiyamu pomwe fiberglass ingakhale. Yopangidwa kuti igwiritsidwe ntchito ndi zida zamagetsi za PCB zamphamvu kwambiri monga magetsi a LED.
Ma PCB Othamanga Kwambiri: Bodi ya ma circuit yopangidwa kuti itumize ma signalo amphamvu ngati 2 GHz.
Kodi ma PCB amapangidwa kuchokera ku chiyani?
Njira yopangira PCB imawoneka yosiyana kutengera cholinga cha chipangizocho komanso kuchuluka kwa mphamvu zomwe zimafunika kuti chipangizocho chigwire ntchito. Musanasankhe zipangizo zomangira bolodi la dera, ndi bwino kudziwa bwino magawo anayi akuluakulu a chipangizo cha PCB:
Gawo lapansi: Chimango cha bolodi la dera — zigawo zonse zimamangiriridwa pamwamba apa.
Laminate: Zipangizo zomwe zimagwirizira zigawo zonse za PCB pamodzi.
Chigoba cha solder: Chimakhala pamwamba pa zojambula zamkuwa kuti chiziteteze ku zinthu zachilengedwe.
Silkscreen: Imamangirira ku chigoba chosungunula kuti zigawo zake zilembedwe.
Kodi chiwembu ndi chiyani?
Chithunzi chojambulidwa, kapena chithunzi chojambulidwa, ndi chithunzi cha zinthu za dongosolo pogwiritsa ntchito zizindikiro zosamveka bwino m'malo mwa zithunzi zenizeni.
Kodi zinthu zomwe zingaperekedwe pa ntchito ya PCB Layout ndi ziti?
Pa maoda a ntchito ya PCB Layout, deta yotsatirayi idzaperekedwa mu fayilo yotulutsa:
Ma database athunthu a Gerber kuphatikiza mafayilo a Drill (Zigawo za Circuit, Zigawo za Mask, Zigawo za Silika, Outline, Zigawo za Drill, Zigawo za Paste)
Deta yosankha & malo

Ndi mitundu yanji ya zipangizo zomwe zimagwiritsidwa ntchito popanga ma PCB olimba?
Zinthu za FR4
Zipangizo zothamanga kwambiri za chizindikiro
Chitsulo cha FR4 chothamanga kwambiri chokhala ndi DF 1Ghz.
Chitsulo cha FR4 chothamanga kwambiri chokhala ndi Df 10Ghz
Zipangizo za ceramic zotsika mtengo, magwiridwe antchito pa 10Ghz
Zinthu za PTFE kapena zinthu za PTFE zolimbikitsidwa
Zinthu za PTFE zotentha kwambiri
Ndi njira ziti zopangira zinthu zomwe zimagwiritsidwa ntchito popanga ma PCB olimba?
Pali njira zambiri zopangira zinthu zomwe zimagwiritsidwa ntchito popanga ma PCB olimba. Njira zotsatirazi zikuphatikizidwa mu njira zambiri.

Kodi zimatenga nthawi yayitali bwanji kupanga PCB yolimba?
Izi zikunena za nthawi yomwe ikufunika kuti pakhale ma PCB olimba mu Richfulljoy.
Zimatenga masiku 1-5 kuti ma PCB okhazikika azigwira ntchito mwachangu.
Masabata 1-2 amatenga kuti apange ma PCB olimba komanso otsatizana pang'ono.
Masabata awiri kapena anayi amagwiritsidwa ntchito popanga ma PCB olimba kwambiri.
Kodi kusiyana kwakukulu ndi kotani: PCB yolimba poyerekeza ndi PCB yosinthasintha?
Kusiyana kwakukulu pakati pa bolodi lolimba la PCB ndi bolodi losinthasintha la PCB ndi:
1), Amapangidwa ndi zinthu zosiyanasiyana: ma board olimba amapangidwa ndi FR4, ceramic, metal core, PTFE etc, onse ndi olimba (sangathe kupindika), pomwe ma PCB osinthasintha amapangidwa ndi polyimide(PI), PET, Kapton matrial omwe amatha kupindika kangapo;
2), Ngati ndi opindika kapena ayi: PCB yolimba siipindika, koma PCB yopindika ndi yopindika;
3), Amagwiritsidwa ntchito mosiyana: ma board okhazikika amagwiritsidwa ntchito muzipangizo zamagetsi zomwe sizisuntha, koma ma board osinthasintha amagwiritsidwa ntchito muzipangizo zomwe nthawi zonse zimayenda, monga makamera, ma laputopu, mafoni am'manja, ma probe osuntha ndi zina zotero.
Kodi ndi ndalama zingati kupanga PCB yolimba?
N'zovuta kunena kuti PCB yolimba ndi ingati. Izi ndi zinthu zazikulu zomwe zimakhudza mtengo wa PCB yolimba.
