1. Zigawo zokhazikika ziyenera kulabadira kukula kwa kulekerera kwa zigawo za opanga osiyanasiyana, zida zosagwirizana ndizomwe ziyenera kupangidwa molingana ndi kukula kwenikweni kwa zithunzi za pad ndi pad spacing.
2. Kamangidwe ka mkulu-kudalirika dera ayenera anakulitsa solder mbale processing, PAD m'lifupi = 1.1 kuti 1.2 nthawi m'lifupi zigawo solder mapeto.
3. Mapangidwe apamwamba kwambiri ku laibulale ya mapulogalamu a zigawo kuti akonze kukula kwa pedi.
4. Mtunda pakati pa zigawo zosiyanasiyana, mawaya, malo oyesera, kupyolera-bowo, mapepala ndi kugwirizana kwa waya, kukana kwa solder, etc. ziyenera kupangidwa motsatira njira zosiyanasiyana.
5. Ganizirani za reworkability.
6. Ganizirani za kutaya kutentha, ma frequency apamwamba, kusokoneza kwa anti-electromagnetic ndi zina.
7. kuyika kwa zigawo ndi malangizo ayenera kupangidwa mogwirizana ndi zofunikira za reflow kapena wave soldering process.Mwachitsanzo, mukamagwiritsa ntchito reflow soldering process, njira yosinthira magawo kuti muganizire momwe PCB ikulowera muvuni yobwereranso.Pamene ntchito yoweyula soldering makina, pamwamba makina sangathe kuikidwa PLCC, FP, zolumikizira ndi zigawo zikuluzikulu SOIC;pofuna kuchepetsa zotsatira za mthunzi wa mafunde, kusintha khalidwe la kuwotcherera, mapangidwe a zigawo zosiyanasiyana ndi malo a zofunikira zapadera;Mawonekedwe a zojambula za wave soldering pad, zigawo zamakona anayi, SOT, SOP zigawo za pedi kutalika ziyenera kukulitsidwa kuti zigwirizane ndi awiri akunja a SOP Wider pads kuti adsorb owonjezera solder, zosakwana 3.2mm × 1.6mm zigawo zamakona anayi, zitha kugwedezeka pa zonse ziwiri. mapeto a pedi 45 ° processing, ndi zina zotero.
8. Mapangidwe a bolodi osindikizidwa amaganiziranso zida.Osiyana oyika makina makina dongosolo, mayikidwe, kufalitsidwa dera bolodi kufala ndi osiyana, kotero udindo wa kusindikizidwa dera bolodi dzenje malo, benchmark chizindikiro (Marko) zithunzi ndi malo, kusindikizidwa dera bolodi m'mphepete mawonekedwe, komanso kusindikizidwa dera m'mphepete pafupi malo a zigawo sangakhoze kuikidwa ndi zofunika zosiyanasiyana.Ngati mafunde a soldering agwiritsidwa ntchito, m'pofunikanso kuganizira kuti m'mphepete mwa makina osindikizira osindikizira amayenera kusiyidwa.
9. Koma ganiziraninso zolemba zofananira.
10. kuchepetsa ndalama zopangira potengera kudalirika.
11. momwemonso kusindikizidwa dera bolodi kamangidwe, ntchito mayunitsi kuyenera kugwirizana.
12. Msonkhano wapawiri-mbali ndi umodzi wa mbali imodzi ya zofunikira zosindikizidwa za board board ndizofanana
13. Koma ganiziraninso zolemba zofananira.
