1: Maziko osankha m'lifupi mwa waya wosindikizidwa: kutalika kochepa kwa waya wosindikizidwa kumagwirizana ndi zomwe zikuyenda pa waya: mzerewu ndi wochepa kwambiri, kukana kwa waya wosindikizidwa ndi kwakukulu, ndi kutsika kwa magetsi. pamzere ndi waukulu, womwe umakhudza magwiridwe antchito a dera. Mzere wa mzerewu ndi Wotambalala kwambiri, kachulukidwe ka mawaya siwokwera, dera la bolodi likuwonjezeka, kuwonjezera pa kuwonjezereka kwa ndalama, sizikugwirizana ndi miniaturization. Ngati katundu panopa amawerengeredwa monga 20A / mm2, pamene makulidwe a mkuwa clad zojambulazo ndi 0.5 MM, (nthawi zambiri kwambiri), katundu panopa wa 1MM (pafupifupi 40 MIL) mzere m'lifupi ndi 1 A, kotero mzere m'lifupi ndi zotengedwa ngati 1-2.54 MM (40-100 MIL) zitha kukwaniritsa zofunikira zonse. Waya wapansi ndi magetsi pa bolodi la zida zamphamvu kwambiri zitha kuwonjezeredwa moyenerera malinga ndi kukula kwa mphamvu. Pamabwalo a digito otsika mphamvu, kuti muwonjezere kachulukidwe wama waya, kutalika kwa Line kungakhutitsidwe potenga 0.254-1.27MM (10-15MIL). Mu bolodi lozungulira lomwelo, chingwe chamagetsi. Waya wapansi ndi wokhuthala kuposa waya wolumikizira.
2: Kutalikirana kwa mizere: Pamene ndi 1.5MM (pafupifupi 60 MIL), kukana kwa insulation pakati pa mizereyo ndi yaikulu kuposa 20 M ohms, ndipo mphamvu yaikulu pakati pa mizere imatha kufika 300 V. Pamene mzere wa mzere ndi 1MM (40 MIL). ), voteji pazipita pakati pa mizere ndi 200V Choncho, pa bolodi dera la sing'anga ndi otsika voteji (voteji pakati pa mizere si oposa 200V), katayanitsidwe mzere amatengedwa ngati 1.0-1.5 MM (40-60 MIL) . M'mabwalo otsika voteji, monga makina ozungulira digito, sikoyenera kuganizira za kuwonongeka kwamagetsi, malinga ndi nthawi yayitali yopangira, ikhoza kukhala yaying'ono kwambiri.
3: Pad: Kwa 1 / 8W resistor, pad lead diameter ndi 28MIL ndiyokwanira, ndipo kwa 1/2 W, m'mimba mwake ndi 32 MIL, dzenje lotsogola ndi lalikulu kwambiri, ndipo m'lifupi mwake mphete ya mkuwa ndiyocheperako, Zomwe zimapangitsa kuchepa kwa kumamatira kwa pedi. Ndikosavuta kugwa, dzenje lotsogolera ndi laling'ono kwambiri, ndipo kuyika kwa chigawocho kumakhala kovuta.
4: Jambulani malire a dera: Mtunda wamfupi kwambiri pakati pa mzere wa malire ndi chigawo cha pini pad sichikhoza kukhala chocheperapo 2MM, (nthawi zambiri 5MM ndi yololera) mwinamwake, n'zovuta kudula zinthuzo.
5: Mfundo ya kamangidwe kagawo: A: Mfundo yaikulu: Pamapangidwe a PCB, ngati pali mabwalo a digito ndi ma analogi mu dongosolo la dera. Komanso mabwalo apamwamba kwambiri, ayenera kuikidwa padera kuti achepetse kugwirizanitsa pakati pa machitidwe. Mumtundu womwewo wa dera, zigawozi zimayikidwa muzitsulo ndi magawo malinga ndi kayendedwe ka kayendedwe kake ndi ntchito.
6: Chigawo chopangira ma siginoloji, chiwongolero chaupangiri wamakina ayenera kukhala pafupi ndi mbali ya bolodi, pangani mzere wolowera ndi wotuluka kukhala waufupi momwe mungathere, kuti muchepetse kusokoneza kwa athandizira ndi kutulutsa.
7: Kuyika kwa gawo: Zigawo zitha kukonzedwa munjira ziwiri, zopingasa komanso zoyima. Apo ayi, mapulagini saloledwa.
8: Kutalikirana kwa zinthu. Kwa matabwa apakati, kusiyana pakati pa zigawo zing'onozing'ono monga zoletsa mphamvu zochepa, ma capacitor, ma diode, ndi zigawo zina zapadera zimayenderana ndi pulagi ndi kuwotcherera. Pakuwotchera mafunde, magawo agawo amatha kukhala 50-100MIL (1.27-2.54MM). Chachikulu, monga kutenga 100MIL, chip chophatikizika chozungulira, malo apakati nthawi zambiri amakhala 100-150MIL.
9: Pamene kusiyana komwe kungakhalepo pakati pa zigawozo kuli kwakukulu, kusiyana pakati pa zigawozo kuyenera kukhala kwakukulu kuti zisawonongeke.
10: Mu IC, decoupling capacitor iyenera kukhala pafupi ndi pini yapansi ya chip. Apo ayi, zotsatira zosefera zidzakhala zoipa kwambiri. M'mabwalo a digito, pofuna kuwonetsetsa kuti magwiridwe antchito odalirika amagetsi amagetsi, ma IC decoupling capacitors amayikidwa pakati pa magetsi ndi pansi pa chipangizo chilichonse chophatikizika cha digito. Decoupling capacitors nthawi zambiri amagwiritsa ntchito ceramic chip capacitors okhala ndi mphamvu ya 0.01 ~ 0.1 UF. Kusankhidwa kwa decoupling capacitor mphamvu nthawi zambiri kumatengera kubwereza kwa ma frequency ogwiritsira ntchito F. Kuphatikiza apo, 10UF capacitor ndi 0.01 UF ceramic capacitor imafunikanso pakati pa chingwe chamagetsi ndi pansi pakhomo la magetsi ozungulira.
11: Gawo la gawo la ola la ola liyenera kukhala pafupi kwambiri ndi pini ya chizindikiro cha wotchi ya chip microcomputer chip kuti muchepetse kutalika kwa kugwirizana kwa wotchi. Ndipo ndibwino kuti musamayendetse waya pansipa.
