Mtengo wopangira gulu ladera lakhala lokhudzidwa kwambiri ndi akatswiri onse opanga zamagetsi, akufuna kuzindikira phindu lalikulu la zinthu zawo ndi mtengo wotsika kwambiri. dziwani zinthu zonse zomwe zingawonjezere mtengo wa PCB yanu.
Chifukwa chachikulu chomwe chimakhudza mtengo wa PCB
1) PCB kukula ndi kuchuluka
Ndizosavuta kumvetsetsa momwe kukula ndi kuchuluka kungakhudzire mtengo wa PCB, kukula ndi kuchuluka kwake kudzadya zida zambiri.
2) mitundu yazinthu zapansi panthaka zomwe zimagwiritsidwa ntchito
Zida zina zapadera zomwe zimagwiritsidwa ntchito m'malo ogwirira ntchito zitha kukhala zokwera mtengo kwambiri kuposa zida zanthawi zonse.Kupanga Mabodi Osindikizidwa Osindikizidwa kumadalira zinthu zingapo zomwe zimagwiritsidwa ntchito, zomwe zimayendetsedwa makamaka ndi ma frequency ndi liwiro la kagwiritsidwe ntchito, komanso kutentha kwakukulu kogwirira ntchito.
3) Chiwerengero cha zigawo
zigawo zambiri zimamasulira kukhala ndalama zowonjezera chifukwa cha masitepe ochulukirapo, zinthu zambiri, komanso nthawi yowonjezera yopanga.
4) PCB zovuta
PCB zovuta zimadalira chiwerengero cha zigawo ndi chiwerengero cha vias pa wosanjikiza aliyense, monga izi limafotokoza kusiyanasiyana kwa zigawo kumene vias kuyamba ndi kusiya pa, chofunika kwambiri lamination ndi kubowola masitepe mu ndondomeko PCB kupanga.Opanga amatanthauzira njira yochepetsera ngati kukakamiza zigawo ziwiri zamkuwa ndi ma dielectrics pakati pa zigawo zamkuwa zoyandikana pogwiritsa ntchito kutentha ndi kukakamiza kuti apange multilayer PCB laminate.
Mitengo yamitengo kuchokera pakupanga pf PCB yokha
1. Tsatirani ndi kusiyana kwa geometry-yoonda ndiyokwera mtengo.
2. Kuwongolera kulepheretsa-njira zina zowonjezera zimawonjezera ndalama.
3. Kukula ndi kuwerengera kwa mabowo-mabowo ambiri ndi ma diameter ang'onoang'ono amakwera pamwamba.
4. plugged kapena kudzazidwa vias ndi ngati mkuwa yokutidwa - njira zina zowonjezera ndalama.
5. Kuchuluka kwa mkuwa m'magulu - makulidwe apamwamba amatanthauza ndalama zambiri.
6. Kutsirizitsa pamwamba, kugwiritsa ntchito golide ndi makulidwe ake-Zinthu zowonjezera ndi masitepe opangira zimachulukitsa mtengo.
7. Kulekerera - kulolerana kolimba kumakwera mtengo.
Zinthu zina zomwe zimakhudza mtengo wa PCB
Izi zing'onozing'ono zamtengo wapatali zokhudzana ndi gulu la III zimadalira onse, wopanga ndi kugwiritsa ntchito PCB.Iwo makamaka akuphatikizapo:
1. NPCB makulidwe.
2.Zochiritsira zosiyanasiyana pamwamba.
3. masking akale.
4. Kusindikiza kwa nthano.
5. Gulu la machitidwe a PCB (IPC Kalasi II/III etc.).
6. PCB contour—makamaka pa z-axis routing.
7. Kupaka m'mbali kapena m'mphepete.
PCBA adzakupatsani malingaliro abwino molingana kukuthandizani kuchepetsa mtengo wa matabwa PCB,
