The PCB dera bolodi akhoza kuphatikiza zigawo zambiri zamagetsi palimodzi, amene angapulumutse malo bwino kwambiri ndipo sangalepheretse ntchito dera. Pali njira zambiri mu kapangidwe ka bolodi dera PCB. Choyamba, tiyenera kukhazikitsa Chongani magawo a bolodi PCB dera. Chachiwiri, tiyenera kugwirizanitsa mbali zosiyanasiyana m’malo ake oyenera.
1. Lowani dongosolo la mapangidwe a PCB ndikukhazikitsa magawo oyenera
Khazikitsani magawo a chilengedwe cha dongosolo la mapangidwe malinga ndi zizoloŵezi zaumwini, monga kukula ndi mtundu wa malo a gridi, kukula ndi mtundu wa cholozera, ndi zina zotero. Kuonjezera apo, magawo monga kukula ndi chiwerengero cha zigawo za bolodi la dera ziyenera kukhazikitsidwa.
2. Pangani tebulo la intaneti lomwe latumizidwa kunja
The netiweki tebulo ndi mlatho ndi ulalo pakati pa dera schematic kamangidwe ndi kusindikizidwa dera bolodi kamangidwe, amene n'kofunika kwambiri. Netlist imatha kupangidwa kuchokera pazithunzi zamadongosolo ozungulira, kapena kuchotsedwa pafayilo ya board yosindikizidwa yomwe ilipo. Pamene tebulo la netiweki likuyambitsidwa, ndikofunikira kuyang'ana ndikuwongolera zolakwika pamapangidwe adongosolo.
3. Konzani malo a gawo lililonse phukusi
Ntchito yokhazikika yokhazikika yadongosolo ingagwiritsidwe ntchito, koma magwiridwe antchito okhazikika siangwiro, ndipo ndikofunikira kusintha pamanja malo a gawo lililonse.
4. Kupanga mawaya a board board
Cholinga cha kayendedwe ka board board ndikukhazikitsa mtunda wachitetezo, mawonekedwe a waya ndi zina. Pakali pano, makina opangira mawaya a zidazo ndi okwanira, ndipo chithunzi chozungulira chikhoza kuyendetsedwa; koma masanjidwe a mizere ina siwokhutiritsa, ndipo mawaya amathanso kuchitidwa pamanja.
5. Sungani ndi chosindikizira chotulutsa kapena kukopera kolimba
Mukamaliza mawaya a bolodi loyang'anira dera, sungani fayilo yomaliza yachithunzichi, ndiyeno gwiritsani ntchito zida zosiyanasiyana zojambulira, monga osindikiza kapena ma plotters, kuti mutulutse chithunzi cha mawaya a board.
Kugwirizana kwamagetsi kumatanthauza kuthekera kwa zida zamagetsi kuti zizigwira ntchito moyenera komanso moyenera m'malo osiyanasiyana amagetsi. Cholinga chake ndikuthandizira zida zamagetsi kuti zitseke zosokoneza zosiyanasiyana zakunja, kuti zida zamagetsi zizigwira ntchito moyenera pamalo enaake amagetsi, komanso kuchepetsa kusokoneza kwamagetsi pazida zamagetsi zokha ku zida zina zamagetsi. Monga operekera maulumikizidwe amagetsi pazigawo zamagetsi, mawonekedwe ofananirako a bolodi yadera la PCB ndi chiyani?
1. Sankhani waya wokwanira m'lifupi mwake. Popeza kusokonezeka kwamphamvu komwe kumapangidwa ndi nthawi yayitali pamizere yosindikizidwa ya bolodi yadera la PCB makamaka chifukwa cha gawo la inductance la waya wosindikizidwa, inductance ya waya yosindikizidwa iyenera kuchepetsedwa.
2. Malinga ndi zovuta za dera, kusankha koyenera kwa nambala yosanjikiza ya PCB kumatha kuchepetsa kusokonezeka kwamagetsi, kuchepetsa kwambiri voliyumu ya PCB ndi kutalika kwa lupu ndi waya wa nthambi, ndikuchepetsa kwambiri kusokoneza pakati pa ma sigino.
3. Kutengera njira yolondola yolumikizira mawaya ndikugwiritsa ntchito mawaya ofanana kungachepetse ma inductance mawaya, koma kulumikizana kolumikizana ndi kugawa mphamvu pakati pa mawaya kudzawonjezeka. Ngati masanjidwewo alola, ndi bwino kugwiritsa ntchito mawaya opangidwa bwino. Njira yeniyeni ndi kupanga mbali imodzi ya kusindikizidwa bolodi yopingasa Mawaya, mawaya mbali ina vertically, ndiyeno kulumikiza ndi mabowo metallized pa maenje mtanda.
4. Pofuna kupondereza crosstalk pakati pa mawaya a bolodi la dera la PCB, yesetsani kupewa mtunda wautali wofanana ndi mawaya popanga mawaya, ndikusunga mtunda pakati pa mawaya momwe mungathere. mtanda. Kukhazikitsa mzere wosindikizidwa pakati pa mizere ina yazizindikiro yomwe imakhala yovuta kwambiri kusokoneza kungathe kupondereza crosstalk
