Mukupanga kwa PCB ndi kupanga kwa PCB komaliza, Pulogalamu ya PCB ndichinthu chofunikira kwambiri, chomwe sichimangotengera mtundu wa PCB, komanso zimakhudzanso mtengo wopangira PCB. Momwe mungatsimikizire mtundu wa board ya PCB, msonkhano wololera komanso wogwira mtima, kuti mupulumutse zopangira, kampani yopanga imafunikira kwambiri kuthana ndi vuto.

1. Njira yolumikizira Collage

Pali mitundu iwiri yolumikizira ya PCB, imodzi ndi V-cut, inayo ndi sitampu yolumikizira. V-kudula nthawi zambiri kumakhala koyenera kwa PCB yokhala ndi mawonekedwe amakona anayi, odziwika ndi m’mphepete mwaukhondo pambuyo podzipatula ndi mtengo wotsika wamagetsi, motero tikulimbikitsidwa kuti tigwiritse ntchito poyamba. Sitampu dzenje nthawi zambiri limakhala loyenera kusanja mbale, mwachitsanzo, mawonekedwe a “L” mbale nthawi zambiri amatengera ulalo wazitsulo kuti asonkhanitse mbaleyo.

2. Chiwerengero cha collage:

Kukula kwa bolodi lonse kuyenera kuwerengedwa molingana ndi kukula kwa bolodi limodzi la PCB. Kukula kwa bolodi lonse sayenera upambana pazipita kukula osiyanasiyana PCB (kutalika kwa bolodi PCB sayenera kuposa 250mm). Mabungwe ochulukirapo amakhudza kulondola kwa bolodi komanso kulondola kwa chip. Nthawi zambiri, bolodi lalikulu la MID kalasi ndi matabwa awiri, ndipo bolodi yaying’ono ya board ndi LCD siopitilira 2. Gulu laling’ono la dera lapadera limatsimikizika malinga ndi momwe zinthu ziliri.

3, sitampu yolumikizira ma bar yolumikizira

Mu PCB Mose, kuchuluka kwa mipiringidzo yolumikizira kuyenera kukhala koyenera, makamaka mipiringidzo yolumikizana ndi 2-3, kuti mphamvu ya PCB ikwaniritse zofunikira pakupanga, ndipo musasweke mosavuta. Chingwe cholumikizira chikapangidwa, nthawi zambiri chimafunikira kupanga kutalika kwa 4-5mm, dzenje losakhala lachitsulo, kukula kwake kumakhala 0.3mm-0.5mm, malo pakati pa mabowo ndi 0.8-1.2mm;

4. Njira yoyeserera

Bolodi ndi wandiweyani, bolodi m’mphepete danga okha, kufunika kuonjezera ndondomeko m’mphepete, ntchito SMT PCB bolodi kufala m’mphepete, ambiri 3-5mm. Nthawi zambiri, bowo loyikapo limaphatikizidwa pamakona anayi am’mbali mwa ndondomekoyi, ndipo malo owunikira amawonjezeredwa pamakona atatu kuti alimbikitse kuyika kwa makina.
