ziviso
Mazuva ano, mabhodhi ematunhu anoshandisa zvimwe zvikamu zveSMD pane plug-in components, asi kune izvo zvigadzirwa zvemagetsi zvine zvakakwirira zvinopisa kupisa zvinodikanwa, kushanda kweplug-in components kuchave kuri nani pane iyo yeSMD components. Pamusoro pezvo, iyo yekunze interface yebhodhi reamai uye zvishandiso zvechibatanidza zvese zvinoshandisa plug-in mapini, akadai se USB, HDMI, network ports, uye zvimwe zvishandiso.
Nezve masikweya mapini eplug-in zvishandiso, pane manufacturability nyaya mukuongorora kweDFM. Mapini emudziyo anowanzo kutenderera kana kuti ovhari, asi mapini emamwe mapini emusoro mapini ane sikweya. Sikweya pini haina kunyatso kurongeka paunenge uchigadzira mapakeji, kunyangwe imwe EDA software inogona kugadzira mapakeji ane sikweya pini. Nekudaro, makomba emapini haagone kuitwa padivi rekugadzira nekuti yekuchera inotenderera.
Square Pin Drawing Method
1. Allegro inodhirowa sikweya pini
Kutanga, vhura iyo Padstack Edhiyo pasuru yekudhirowa chishandiso. Munguva yekudhirowa kwepakeji, ingo shandura iyo Hole mhando yeDrill kuSquare. Chimiro che plug-in pin chinonzi square.
2. PADS inodhirowa sikweya pini
PADS software haina basa rekudhirowa sikweya pini. Kana mapini eplug-in akaenzana uye achida kugadziridzwa kwakakosha, unogona kushandisa mitsara ye2D muDrill Drawing layer kudhirowa rectangles zvinoenderana nehukuru hwepini, uye shandisa mavara kuratidza chaizvo kuti sikweya pini gomba rinodiwa pano.
Square Pin Processing Method
1. CAM software kuzivikanwa kwemakomba makomba
Kune masikweya makomba, iripo CAM software haigone kuaziva uye inogona kungoziva denderedzwa kana elliptical maburi uye slots. Wonderfulpcb DFM sevhisi inogona kuziva masikweya ekuboora maburi uye maburi anopinza uye inogona kuongorora mafaera ekugadzira ane masikweya makomba, ichikurudzira kuti mafaera ekugadzira ane masikweya maburi kudzivirira kushayikwa masikweya ekuboora maburi panguva yekugadzira.
2. Kugadzirisa nzira yemakomba makomba uye masikweya slots mukugadzira
Parizvino, muchina wekuchera muindastiri haugone kuchera makomba akaenzana, nekuti chibooreso chemuchina wekuchera chinoboora maburi anodiwa nePCB board kuburikidza nekumhanya-mhanya kutenderera, saka maburi akaboorwa ane denderedzwa kana elliptical.
Saka sei kugadzirisa dambudziko remakomba makomba? Muchina wekuchera unogona chete kusangana neskweya gomba zvinodiwa nekuchera mamwe makomba. Semuyenzaniso, tanga waboora gomba rakaita denderedzwa zvichienderana nehupamhi hwepini, woboora maburi madiki mana pamakona kuti asangane nesquare pin plug-in zvinodiwa.
3. Kuganhurirwa kwesquare hole processing
Kunyangwe zvakanyorwa pamusoro apa kuti kune nzira yekugadzira makomba makomba, maburi akacherwa ane denderedzwa mushure mezvose. Kunyangwe kana maburi madiki akashandiswa kuchera makona masikweya, 100% kona yekurudyi haigone kuwanikwa. Kana paine kutsauka kudiki, mudziyo haugone kuiswa.
Naizvozvo, zvinokurudzirwa kuti mainjiniya edhizaini adhirowe saizi yepini yakakura zvishoma pakudhirowa mapini epasuru kudzivirira dambudziko remudziyo kusakwanisa kuiswa mushure mekugadzirwa.
