PCB ConsnelMalamulo ndi Njira
1. Malinga ndi njira zomwe zingafunikire mafakiti osiyanasiyana, kukula kwakukulu ndi kukula kochepa kwa gululi kuyenera kumveka bwino. Nthawi zambiri, pcb yaying'ono kuposa 80x80mmm ayenera kukhala wokonzeka kukhala wophatikizika, ndipo kukula kwakukulu kumadalira pakupanga fakitaleyo. Mwachidule, kukula kwa PCB kuyenera kukwaniritsa zofunikira zaZida za SMTZoyenera, zomwe zimapangitsa kuti pakhosi ya SMT ndikuthandizira kusankha makulidwe a PCB.
2. Msonkhano ndi sub-by-bolod uyenera kukwaniritsa zofunikira za DFM ndi DFA, ndipo nthawi yomweyo onetsetsani kuti msonkhano wa PCB umakhazikika ndipo sakuwonongeka mosavuta Kugawidwa pakati pa mapanelo kuyenera kukwaniritsa zofuna za pansiPnbaChip Kukonzekera.
3. Mu ma PCBjambula, makonzedwe a zinthu zikuluzikulu ayenera kupewa kugawanitsa nkhawa ndikuyambitsa ming'alu yoyambitsa. Kugwiritsa ntchito kapangidwe kake kazidutswa kakale kumatha kuchepetsa nkhondo ndi kuphatikizika panthawi yolekanitsa, ndikuchepetsa nkhawa pazinthu. Osachepera, yesetsani kuti musayike zofunikaZidaEnakuntchito.
4. Kukula kwake ndi mawonekedwe a gululi amathandizidwa malinga ndi polojekiti yake, ndipo mawonekedwe ake ali pafupi ndi lalikulu momwe mungathere. Ndikulimbikitsidwa kugwiritsa ntchito 2 × 2 kapena 3 × 3 njira. Sitikulimbikitsidwa kuphatikiza yin ndi yang panels ngati sikofunikira;
5. Nambala ya chiwonetsero cham'mphepete mwa matabwa ophatikizikapambuyo potchedwe.
6. Pambuyo pa gulu la Panel, ziyenera kutsimikiziridwa kuti m'mphepete mwa bolodi ili ndi 1.5mm kutali ndi masitima a pcb ndi 3. Osayika mfundo zomveka bwino, kotero kuti mbali yosinthira / yosinthira ya PCB imatha kulowa makinawo kudzera mu chizindikiritso cha chipangizocho.
7. Pamene makulidwe aPCB Boardndizochepera kuposa 1.0mm, mphamvu ya gulu lonselo lidzachepetsedwa kwambiri (kufooka) pomwe mabowo ophatikizika amawonjezeredwa, chifukwa nsala ya ming'alu yagalasi v yathyoka mphamvu. Ngati sichikuthandizidwa ndi nthitila, chidzakhudza njira yomwe ili pansipa ya PCBA.
8.. Pakakhalazala zagolidePa PCB, nthawi zambiri ikani zala zagolide kunja kwa bolodi kulowera kwa malo omwe siwogawika. M'mphepete mwa chala chagolide sichingatulutsidwe kapena kukonzedwa.
