Maitiro ekudzivirira Makomba eMadiki-Sizi Makomba uye Slots mumapini eChishandiso?
PCB board yemapini eplug-in mudziyo inoda kudhonzwa kuti uise mudziyo, PCB kuchera inzira yekugadzira ndiro yePCB, idanho rakakosha zvakare. Kunyanya kune maburi ebhodhi, kurongeka kunoda kutamba gomba, chimiro chinoda kuroverwa kuita chinzvimbo, plug-in zvishandiso zvinoda kutamba maburi epini uye zvichingodaro; multi-layer board drilling haisi yenguva imwe chete yekutamba kuburikidza, mamwe maburi anovigwa mubhodhi, mamwe ebhodhi pamusoro pepunch kuburikidza, saka pachave nekudhirowa maviri ekuboora.
1. USB mudziyo pini oval slot uye USB mhando mudziyo goko mapini anowanzo ari oval pini, mamwe mapini e USB mudziyo idiki, saka dhizaini yegomba re slot idiki pane yekugadzira process kugona.
Nekuti indasitiri diki yekuchera muchina slot banga ingori 0.6mm, kana dhizaini yegomba iri pasi pe0.45mm haigone kugadzirwa. Semuenzaniso: dhizaini yepini yepini gomba ingori 0.3mm, kugadzirwa kwekushandiswa kwe0.6mm slotting banga kuchera, gomba ndokuzoputirwa nemhangura mushure mekupedzwa kwechigadzirwa aperture iri 0.45mm, iyo yakapedzwa chigadzirwa aperture yakakura kupfuura pini aperture dhayamita ye0.15mm, iyo yakanyanya-kushivirira mudziyo haina kuchengetedzwa. Naizvozvo, zvinokurudzirwa kugadzira pini slot hole yakakura kupfuura 0.45mm.
2. Maburi epini ezvikamu zve wiring uye mapini ezvimwe plug-in zvikamu zviduku zvikuru. Kana iyo plug-mugomba yakagadzirwa isingasviki 0.5mm, gomba repini rinogona kubatwa zvisizvo senzira pakupera kwekugadzira. Kunyanya mafaira akagadzirwa neAltium Designer software, vias zvose zvine mahwindo kana outputting Gerber, saka zviri nyore kuvhiringa diki mudziyo pini maburi pamwe vias.
Kana iyo plug-mugomba repini ikabatwa zvisizvo sevhaira, dambudziko nderekuti mudziyo haugone kubatirwa mukati pasina muripo wekuvhura, kana hwindo rinodzimwa pamwe chete neiyo via. Iyo padhi inogadzirwa nemafuta evhavha uye haigone kusungirirwa.
3. yakakwira-voltage yekuzviparadzanisa nevamwe kudzivirira pcb creepage milling slot, magetsi emagetsi mabhodhi anowanzo mubhodhi achagadzirirwa kuparadzanisa slot. Kuguma kwekugadzira kwediki diki rekucheka dhayamita inosvika 0.8mm. isingasviki 0.8mm milling slot haisi nyore kugadzira, mutengo wakakwira zvakanyanya.
Yese isiri-simbi inotsvedza mubhodhi inokurudzirwa kugadzirwa yakakura kupfuura 0.8mm. Zvisina-metallic grooves hazvidi kuve nemhangura-yakaputirwa, kusarudzwa kwezvigayo grooves kuderedza mari yevakawanda, mari yekuchera grooves yakakwirira, uye kushanda kunononoka. Nokudaro, zvinokurudzirwa kuti dhizaini yezvisina-metallic grooves pamagumo ekugadzirwa kwekugadzirwa kwepamusoro kupfuura 0.8mm.
Magadzirirwo mainjiniya kazhinji kubvunza bhodhi fekitari kugadzirwa, redunhu bhodhi kuchera muripo yakawanda sei, maererano chii kushivirira muripo, kunyanya anokwira makomba (Positioning makomba) uye plug-mumakomba, kana muripo usiri panzvimbo kana dhizaini isiri panzvimbo, zvichakanganisa kugadzirwa kwese uye kugadzwa kwebhodhi redunhu rinoshandiswa.
General circuit board makomba akakamurwa kuva marudzi maviri emakomba, imwe ine mhangura uye isina makomba emhangura, mhangura inonyanya kushandiswa pakusunga uye makomba makomba, hapana mhangura inonyanya kushandiswa kukwirisa nekuisa chinzvimbo.
Kana iri metallization drilling, tinoda kuchera makomba asina mhangura paPCB kutanga, tobva taisa chidimbu chemhangura foil pamadziro egomba, zvino kana tin yekupfapfaidza ichida kuumba 0.1-0.15mm, kureva kuti, mudziyo wekuchera unofanirwa kushandiswa 0.2-0.25mm, zvichienderana nehukuru hwekugadzira uye fekitori yekugadzira imwe neimwe michina uye fekitori. kana iri OSP, goridhe plating process inoda kuita 0.05-0.1mm kana zvakadaro; kana iri OSP, goridhe plating process inoda kuita 0.05-0.1mm kana zvakadaro; kana iri OSP, goridhe plating process inoda kugadzira 0.05-0.1mm kana zvakadaro. Iyo chaiyo saizi inoenderana nekugadzira maitiro uye michina michina yefekitori yega yega.
Kana iri gomba risina-metalized, kureva kuti, pasina gomba remhangura, ipapo muripo wemuripo unosvika 0.05mm, semuenzaniso, 0.1mm gomba inoda kushandisa 0.15mm yekuchera chishandiso, hongu, kazhinji hapana gomba remhangura igomba rakakura, zvinoenderana nehukuru chaihwo kuita muripo wekugadzirisa.
Madhizaini mainjiniya kazhinji haafanire kufunga nezve saizi yemubhadharo wefekitori yebhodhi mukugadzira, mugadziri mukuru mukuita maitiro anozomira kune dhizaini yegomba ruzivo rweakapedzwa gomba saizi, dhizaini bhodhi mugadziri achange ari mukugadzira ruzivo, otomatiki rakagadzirirwa kutsiva kushivirira. Gadzira saizi yegomba inodiwa neinjiniya yekugadzira.
