I. Padiyo ikudutsana
1. Kuphatikizika kwa mapepala (kuphatikiza pa phala la pamwamba) kumatanthauza kuti kuphatikizika kwa mabowo, pobowola kumabweretsa kubowola kosweka chifukwa cha kubowola kangapo pamalo amodzi, zomwe zimabweretsa kuwonongeka kwa dzenje.
2. Multilayer bolodi mu mabowo awiri alipo, monga dzenje kwa kudzipatula litayamba, dzenje lina kwa kugwirizana litayamba (maluwa ziyangoyango), kuti pambuyo kujambula kunja ntchito zoipa kudzipatula litayamba, chifukwa mu zidutswa.
II.Kugwiritsa ntchito molakwika kwa graphics layer
1. Ena zithunzi wosanjikiza kuchita kugwirizana achabechabe, poyamba anayi wosanjikiza bolodi koma anapanga oposa zigawo zisanu za mzere, kuti chifukwa cha kusamvana.
2. Design kupulumutsa nthawi, Protel mapulogalamu Mwachitsanzo, kuti zigawo zonse za mzere ndi Board wosanjikiza kujambula, ndi Board wosanjikiza zikande chizindikiro mzere, kuti pamene kuwala kujambula deta, chifukwa Board wosanjikiza sanasankhidwe, anaphonya kugwirizana ndi kuswa, kapena adzakhala yochepa-circuited chifukwa cha kusankha Board wosanjikiza wa mzere chizindikiro, kotero kamangidwe kusunga umphumphu wa zithunzi wosanjikiza ndi bwino.
3. Motsutsa mapangidwe ochiritsira, monga chigawo chapamwamba kamangidwe mu Pansi wosanjikiza, kuwotcherera pamwamba kamangidwe Pamwamba, chifukwa cha vuto.
III.Makhalidwe a kuyika kwachisokonezo
1. The khalidwe chivundikiro ziyangoyango SMD solder lug, kwa bolodi kusindikizidwa kudzera mayeso ndi chigawo kuwotcherera vuto.
2. Kapangidwe kake ndi kakang'ono kwambiri, kumayambitsa zovuta mumakina osindikizira a skrinikusindikiza, kwakukulu kwambiri kuti zipangitse zilembo kuti zigwirizane, zovuta kuzisiyanitsa.
IV.Zokonda pa kabowo kakang'ono ka mbali imodzi
1. Mapadi a mbali imodzi nthawi zambiri sabowoledwa, ngati dzenje likufunika kulembedwa, pobowola ayenera kupangidwa kuti ziro.Ngati mtengo wapangidwa kuti pamene deta pobowola kwaiye, malo awa amaonekera mu dzenje makonzedwe, ndi vuto.
2. Mapadi a mbali imodzi monga kubowola ayenera kulembedwa mwapadera.
V. Ndi chipika chodzaza kuti mujambule mapepala
Ndi filler block chojambulira pad mapangidwe mzere akhoza kudutsa cheke DRC, koma processing sizingatheke, kotero kalasi pad sangathe mwachindunji solder kukana deta, pamene pa solder kukana, filler chipika malo adzaphimbidwa ndi Solder amakana, zomwe zimapangitsa kuti chipangizocho chikhale chovuta.
VI.Chigawo chamagetsi chamagetsi chimakhalanso ndi maluwa ndipo chimagwirizanitsidwa ndi mzere
Chifukwa magetsi opangidwa ngati njira yamaluwa a maluwa, pansi ndi chithunzi chenichenicho pa bolodi losindikizidwa ndi chosiyana, mizere yonse yolumikizana ndi mizere yodzipatula, yomwe wopangayo ayenera kukhala momveka bwino.Apa ndi njira, kujambula magulu angapo a mphamvu kapena angapo pansi kudzipatula mzere ayenera kusamala kusiya kusiyana, kotero kuti magulu awiri a mphamvu yochepa dera, kapena kungachititse kugwirizana dera oletsedwa (kuti gulu la mphamvu yalekanitsidwa).
VII.Mulingo wokonzekera sunafotokozedwe bwino
1. A limodzi gulu kapangidwe mu TOP wosanjikiza, monga osati kuwonjezera kufotokoza zabwino ndi zoipa kuchita, mwina zopangidwa kuchokera bolodi wokwera pa chipangizo osati kuwotcherera bwino.
2. mwachitsanzo, kapangidwe ka bolodi lamagulu anayi pogwiritsa ntchito TOP mid1, mid2 pansi zigawo zinayi, koma kukonza sikuyikidwa mu dongosolo ili, lomwe limafuna malangizo.
VIII.Mapangidwe a block filler kwambiri kapena blocker block yokhala ndi mzere woonda kwambiri
1. Pali kutayika kwa deta yojambula yowala yopangidwa, deta yojambula yowala siikwanira.
2. Chifukwa chodzaza chipika chojambula chojambula chojambula chojambula chimagwiritsidwa ntchito mzere ndi mzere kujambula, choncho kuchuluka kwa deta yojambula yopangidwa ndi yochuluka kwambiri, kunawonjezera kuvutika kwa deta.
IX.Pad chipangizo chokwera pamwamba ndi chachifupi kwambiri
Izi ndi zoyeserera, pazida zowundana kwambiri zokwera pamwamba, malo pakati pa mapazi ake awiri ndi ochepa, padiyo ndi yopyapyala kwambiri, singano yoyeserera, iyenera kukhala mmwamba ndi pansi (kumanzere ndi kumanja) malo okhazikika, monga pad kapangidwe ndi lalifupi kwambiri, ngakhale sizimakhudza unsembe chipangizo, koma adzapanga mayeso singano molakwika osati lotseguka malo.
X. Kutalikirana kwa gululi ndi kochepa kwambiri
Kupanga lalikulu dera gululi mzere ndi mzere pakati pa m'mphepete ndi laling'ono kwambiri (zosakwana 0.3mm), mu kupanga ndondomeko kusindikizidwa dera bolodi, chithunzi kutengerapo ndondomeko pambuyo chitukuko cha mthunzi n'zosavuta kutulutsa zambiri wosweka filimu. zomangirizidwa ku bolodi, zomwe zimapangitsa mizere yosweka.
XI.Chojambula chachikulu chamkuwa chochokera kunja kwa mtunda ndichoyandikira kwambiri
Large m'dera mkuwa zojambulazo ku chimango chakunja ayenera kukhala osachepera 0.2mm katayanitsidwe, chifukwa mu mawonekedwe mphero, monga mphero kwa zojambulazo mkuwa n'zosavuta chifukwa mkuwa zojambulazo warping ndi chifukwa cha vuto la kukana solder kutali.
XII.Maonekedwe a mapangidwe a malire samveka bwino
Makasitomala ena mu Keep layer, Board layer, Top over layer, etc. adapangidwa mzere wowoneka bwino ndipo mizere iyi simadumphadumpha, zomwe zimapangitsa opanga ma pcb kukhala ovuta kudziwa kuti ndi mzere wotani womwe uyenera kukhala.
XIII.Mawonekedwe osagwirizana
Osafanana plating wosanjikiza pamene plating zithunzi zimakhudza khalidwe.
XIV.Malo oyikapo mkuwa ndi okulirapo kwambiri mukamagwiritsa ntchito mizere ya gridi, kupewa matuza a SMT.
