Njira zonse zoyambira kupanga PCB ndi izi:

Kukonzekera koyambirira → kapangidwe ka PCB kapangidwe kake → mndandanda wazowongolera → kukhazikitsidwa kwamalamulo → mapangidwe a PCB → kulumikizana ndi magudumu → kukhathamiritsa kwa waya ndi mawonekedwe a silika → ma netiweki ndi cheke cha DRC ndi cheke cha kapangidwe → zojambula zowunikira → kujambula kopepuka → Ndemanga ya PCB board / data yotsimikizira Chitsimikiziro cha projekiti EQ → chigamba chazotulutsa → kumaliza ntchito.

1: Kukonzekera

Izi zikuphatikiza kukonzekera malaibulale aphukusi ndi masamu. Before Kupanga kwa PCB, Tiyenera kukonzekera phukusi la schematic SCH komanso laibulale ya phukusi la PCB. Malaibulale a phukusi atha kubwera ndi PADS, koma ndizovuta kupeza malo owerengera oyenera onse. Ndikofunika kupanga malaibulale anu phukusi molingana ndi kukula kwakanthawi pazida zomwe mwasankha. M’malo mwake, laibulale yonyamula ma PCB iyenera kuchitidwa kaye, kenako maganizidwe a SCH akuyenera kuchitidwa. PCB ma CD laibulale amafuna mkulu, amene amakhudza mwachindunji unsembe bolodi; Zofunikira pakapangidwe ka SCH ndizosasunthika, bola kutanthauzira kwa zikwangwani za pini ndi ubale womwewo ndi ma CD a PCB pamzerewu. PS: Onani zikhomo zobisika mulaibulale yanthawi zonse. Ndiye kapangidwe koyeserera, kokonzeka kupanga kapangidwe ka PCB.

2. kapangidwe ka PCB

Mu gawo ili, malinga ndi kukula kwa bolodi la dera ndi mawonekedwe amakanema, PCB board pamwamba imakopeka ndi kapangidwe ka PCB, ndi zolumikizira, mabatani / ma swichi, mabowo opangira, mabowo amisonkhano ndi zina zotero zimayikidwa malingana ndi malo omwe mukufuna. Ndipo ganizirani mozama ndikudziwitseni malo oyimitsira mawaya komanso malo opanda waya (monga kuchuluka kwa bowo loyenda mozungulira malo opanda waya).

3: kalozera wapa tebulo

It is recommended to route the net table into the board frame first. Import a board enclosure in DXF format or EMN format

4: Kukhazikitsa malamulo

Reasonable rules can be set according to the specific PCB design. These rules are PADS constraint managers, which can be used to restrict line width and safe spacing at any point in the design process. Non-conforming areas are marked by DRC Markers during SUBSEQUENT DRC testing.

The general rule setting is placed before the layout, because sometimes some fanout work needs to be completed during the layout, so the rules should be set well before the FANout. When the design project is larger, the design can be completed more efficiently. Chidziwitso: Malamulo amakhazikitsidwa kuti apange bwino komanso mwachangu, mwanjira ina, kuti opanga akhale ovuta. Zikhazikiko Zodziwika ndi: Sankhani ndikukhazikitsa bowo. 3. Khazikitsani m’lifupi mwake ndi utoto wazizindikiro zofunika ndi magetsi. 4. Board layer Settings.

5: mawonekedwe a PCB

Need to pay special attention to, in place of components, components should be considered when the actual size (in the area and height) and the relative position between the components, to ensure that the electrical properties and production of circuit board installation convenience and feasible sex at the same time, should be on the premise of guarantee the above principle to reflect, appropriate change device, make it tidy and beautiful, Mwachitsanzo, chipangizo chomwecho chiyenera kuyikidwa mwaukhondo komanso mbali yomweyo, osati “kungoyendetsedwa mwachisawawa”. Gawo ili likukhudzana ndi kuvuta kwa gulu limodzi ndi digiri ina ya wiring, ndikufuna kuyesetsa kwambiri kuti muganizire choncho. Pakapangidwe, kakhoza kupanga zingwe zoyambirira osati malo ovomerezeka, kulingalira kokwanira.

Kulumikizana ndi njira yofunikira kwambiri pakupanga kwa PCB. Izi zidzakhudza mwachindunji magwiridwe antchito a PCB board. M’kati kapangidwe PCB, Kulumikizana ambiri ali magulu atatu a magawano: woyamba ndi yogawa, ndilo lamulo zofunika kwambiri za kapangidwe PCB. If the line is not cloth, get everywhere is flying line, it will be a unqualified board, can say that there is no entry.

Chachiwiri ndichokhutira ndi magwiridwe antchito amagetsi. Uwu ndiye muyezo woyesa ngati bolodi losindikizidwa lili loyenerera. Izi zitatha kugawidwa, sinthani mosamala zingwezo, kuti zithe kugwira bwino ntchito zamagetsi. Ndiye pali zokongoletsa. Ngati nsalu yanu yolumikizidwa idalumikizidwa, musakhale ndi malo omwe zimakhudza magwiridwe antchito amagetsi, koma muziyang’ana mopyola muyeso, onjezani zokongola, zowala, zomwe zimawerengera momwe magwiridwe antchito anu amagetsi aliri abwino, akadakhala zinyalala m’maso mwa ena. Izi zimabweretsa zovuta pakuyesa ndi kukonza. Kulumikizana kuyenera kukhala koyenera komanso yunifolomu, osadutsa popanda malamulo. Zonsezi ziyenera kukwaniritsidwa potengera kuwonetsetsa kuti magetsi akugwira ntchito ndikwaniritsa zofunikira zina, apo ayi ndikusiya zomwe zili.

Wiring is mainly carried out according to the following principles: (1) In general, the power line and ground wire should be wired first to ensure the electrical performance of the circuit board. Potengera momwe zinthu zilili, tithandizireni kukulitsa kuchuluka kwa magetsi, waya wapansi, waya woyenera kwambiri ndi wokulirapo kuposa mzere wamagetsi, ubale wawo ndi: waya wapansi> mzere wamagetsi> mzere wazizindikiro, nthawi zambiri amakhala mzere wazizindikiro ndi: 0.2 ~ 0.3mm (about 8-12mil), the narrowest width up to 0.05 ~ 0.07mm (2-3mil), the power cord is generally 1.2 ~ 2.5mm (50-100mil). PCB yoyendetsa digito itha kugwiritsidwa ntchito ngati dera lokhala ndi ma conductor apansi, ndiye kuti, netiweki yapansi (nthaka yoyendera dera la analog singagwiritsidwe ntchito motere). (2) pasadakhale zofunikira kwambiri pamzerewu (monga mafupipafupi) zingwe, kulowetsa ndi kutulutsa mzere mbali ziyenera kupewa kufanana moyandikana, kuti zisatulutse zosokoneza. When necessary, ground wire should be added to isolate, and the wiring of two adjacent layers should be perpendicular to each other, which is easy to produce parasitic coupling in parallel. (3) chipolopolo cha oscillator chakhazikika, ndipo mzere wa wotchi uyenera kukhala waufupi momwe ungathere, ndipo sungakhale paliponse. Pansi pamasekondi oyenda, gawo lapamwamba kwambiri lalingaliro liyenera kukulitsa nthaka, ndipo lisapite kumizere ina, kotero kuti magetsi ozungulira amakhala zero;

(4) Gwiritsani ntchito 45 ° wiring wiring mpaka momwe zingathere, osati 90 ° mzere wosweka, kuti muchepetse cheza cha ma frequency frequency signal; (5) Chingwe chilichonse sichiyenera kupanga chingwe, ngati sichingapeweke, malowo ayenera kukhala ochepa momwe angathere; Chizindikiro chopyola mu bowo chizikhala chocheperako; (6) Mzere wachinsinsi uyenera kukhala waufupi komanso wandiweyani momwe ungathere, ndipo malo oteteza ayenera kuwonjezeredwa mbali zonse ziwiri. (7) when transmitting sensitive signals and noise field signals through flat cables, it is necessary to use the way of “ground line – signal – ground line”. (8) Malo oyeserera amayenera kusungidwa kuti azisainira zofunikira kuti athe kuyeserera pakupanga ndi kukonza. (9) Pambuyo pokonza zolumikizira mwatsatanetsatane, zolumikizira ziyenera kukonzedwa; Nthawi yomweyo, cheke choyambirira ndi ma cheke a DRC atakhala olondola, waya wapansi umadzazidwa mderalo popanda waya, ndipo dera lalikulu lamkuwa limagwiritsidwa ntchito ngati waya wapansi, ndipo malo osagwiritsidwa ntchito amalumikizidwa ndi nthaka monga waya wapansi pa bolodi losindikizidwa. Kapena mupange bolodi losanjikiza, magetsi, mzere wokhazikika aliyense amakhala wosanjikiza.

(1) Line Generally, the signal line width is 0.3mm(12mil), and the power line width is 0.77mm(30mil) or 1.27mm(50mil); The distance between wire and wire and between wire and pad should be greater than or equal to 0.33mm(13mil). In practical application, it should be considered to increase the distance when conditions permit; Makulidwe akapangidwe kamene kali pamwamba, ndibwino (koma osavomerezeka) kugwiritsa ntchito zingwe ziwiri pakati pazikhomo za IC. Kutalika kwa zingwe ndi 0.254mm (10mil), ndipo mtunda pakati pa zingwe sizochepera 0.254mm (10mil). Pazifukwa zina, pini ya chipangizocho ikakhala yothinana ndipo m’lifupi mwake ndi yopapatiza, mzere wazitali ndi utali wa mizere ukhoza kuchepetsedwa moyenera. (2) PAD (PAD) PAD (PAD) ndi dzenje losinthira (VIA) zofunika ndiz: kukula kwa diski kuposa bowo lalikulu kuposa 0.6mm; Mwachitsanzo, ma pin resistors, ma capacitors ndi ma circuits ophatikizika, pogwiritsa ntchito disk / hole size 1.6mm /0.8mm (63mil / 32mil), socket, pini ndi diode 1N4007, pogwiritsa ntchito 1.8mm / 1.0mm (71mil / 39mil). Pogwiritsira ntchito, ziyenera kutsimikiziridwa molingana ndi kukula kwa zinthu zenizeni. Ngati zinthu zilipo, kukula kwa pedi kungakwere moyenera. Kukhazikitsa kwa magawo opangidwa pa PCB kuyenera kukhala pafupifupi 0.2 ~ 0.4mm (8-16mil) wokulirapo kuposa zikhomo zenizeni za zikhomo za zinthuzo. (3) Perforation (VIA) nthawi zambiri imakhala 1.27mm / 0.7mm (50mil / 28mil); Pamene kachulukidwe kake kakachuluka, kukula kwa dzenje kumatha kuchepetsedwa moyenera, koma osati kocheperako, kumatha kulingalira za 1.0mm / 0.6mm (40mil / 24mil). PAD and VIA: ≥ 0.3mm (12mil) PAD and PAD: ≥ 0.3mm (12mil) PAD and TRACK: ≥ 0.3mm (12mil) TRACK and TRACK: ≥ 0.3mm (12mil) ≥ 0.3mm (12mil) PAD ndi VIA: ≥ 0.254mm (10mil) PAD ndi TRACK: ≥ 0.254mm (10mil) PAD ndi TRACK: ≥ 0.254mm (10mil) TRACK ndi TRACK: ≥ 0.254mm (10mil)
