Timathandiza dziko kukula kuyambira 1983

ndi malamulo a kamangidwe PCB mu chikhalidwe ndi chiani?

PCB gulu Kulumikizana ndi chimodzi mwa zinthu zofunika kuti sangathamange. Pcb Kulumikizana zachokera schematics magetsi ndi waya tebulo ndi chofunika waya m'lifupi ndi cm Kamangidwe kusindikizidwa waya, Kulumikizana iyenera kutsatira malamulo otsatirawa:

1. Pa chiyembekezo wokhutiritsa zofunika ntchito, dongosolo la kusankha njira Kulumikizana ndi umodzi wosanjikiza → wosanjikiza woyamba → multilayer, yemwe ndi Kulumikizana akhoza m'Chingelezi chosavuta.

2. chizindikiro pa wosanjikiza yemweyo wa gulu Pcb akasintha kolowera ndi limbikitsa kapena kusintha yosalala, ndi utali wozungulira kupindika ndi bwinoko, kupewa magetsi kumunda ndende, mbendera kusinkhasinkha ndi impedance zina.

3. Kamangidwe Kulumikizana pakati pa ziyangoyango awiri kugwirizana yaifupi ngati n'kotheka, ndi chizindikiro tcheru ndi zizindikiro kakang'ono kupita choyamba. Kuchepetsa mwamsanga ndi kuwasokoneza wa chizindikiro yaing'ono. Chishango grounding Ko kuikidwa pambali pa mzere Muzifunsa dera la analogi; kamangidwe wa chomwecho wosanjikiza wochititsa ayenera wogawana kugawa. M'dera conductive pa chilichonse waya ayenera kukhala moyenera kuteteza gulu warpage.

4. Intaneti madera ndiponso madera analogi ayenera anapambulwa pa Kulumikizana ndi kuti kulowerera ndi mzake.

5. Pamene zigawo dera pa bolodi Pcba ali ochirimika ndi olumikizidwa kwa magetsi, kuda ayenera kukhala lalifupi ngati n'kotheka ndi pafupi zotheka kuchepetsa kukana mkati mwa gulu pcb.

6. zotalika Ine / O mizere madera mkulu-liwiro, monga O mizere angapo Ine / ndi masiyanidwe amplifiers ndi amplifiers moyenera, ayenera kukhala ofanana. Kupewa kuchedwa zosafunika kapena gawo kosangalatsa.

7. kuda pa aliyense wosanjikiza bolodi multilayer akhale perpendicular kwa wina ndi mzake kuchepetsa lumikiza. Pewani mayikidwe ndi muyezo wa zigawo chapamwamba ndipo m'munsi.

8. PAD ndi chikugwirizana ndi m'dera conductive a lalikulu ndi zazing'ono, ayenera insulated ndi waya woonda ndi kutalika osachepera 0.5mm. M'lifupi mwa waya woonda sayenera zosakwana 0.13mm.

9. waya pafupi m'mphepete mwa dera bolodi kusindikizidwa ayenera kukhala woposa 5mm m'mphepete mwa dera bolodi kusindikizidwa. Waya pansi angayandikire m'mphepete mwa bolodi pamene chofunika. Ngati chiongoko njanji ndi kuti anaikapo pa processing wa dera bolodi kusindikizidwa, mtunda pakati pa waya ndipo gulu ayenera kukhala osachepera wamkulu kuposa mozama za njanji kalozera.

FASTPCBA Technology Co., Ltd ndi katswiri PCB wopanga ku China, Shenzhen. Ndi zaka 14 chitukuko, FASPCBA inasanduka woyamba kalasi amapanga HDI PCB, ndi imapanga kupanga 35,000 lalikulu meters.If mukufuna kuphunzira zambiri  PCB , lemberani: pcba06@pcb-smt.net
