Basic malamulo kamangidwe chigawo

1. Kukonzekera molingana ndi ma modules ozungulira, ndi maulendo okhudzana nawo omwe amazindikira ntchito yomweyo amatchedwa module. Zomwe zili mu gawo la dera ziyenera kutengera mfundo ya ndende yapafupi, ndipo dera la digito ndi dera la analogi liyenera kupatulidwa;

2. Palibe zigawo kapena zida zomwe zidzakwezedwa mkati mwa 1.27mm za mabowo osakwera monga mabowo oyika, mabowo okhazikika, ndi 3.5mm (kwa M2.5) ndi 4mm (kwa M3) kwa 3.5mm (kwa M2.5) ndi 4mm (kwa M3) sidzaloledwa kukwera zigawo;

3. Pewani kuika vias pansi yopingasa wokwera resistors, inductors (mapulagi-ins), capacitors electrolytic ndi zigawo zina kupewa yochepa-circuiting vias ndi chigawo nyumba pambuyo soldering yoweyula;

4. Mtunda pakati pa kunja kwa chigawocho ndi m'mphepete mwa bolodi ndi 5mm;

5. Mtunda pakati pa kunja kwa chigawo chokwera ndi kunja kwa gawo loyandikana nalo ndi lalikulu kuposa 2mm;

6. Zigawo zipolopolo zachitsulo ndi zitsulo (mabokosi otetezera, ndi zina zotero) sizingakhudze zigawo zina, sizingakhale pafupi ndi mizere yosindikizidwa, mapepala, ndi kutaya kwawo kuyenera kukhala kwakukulu kuposa 2mm. Kukula kwa mabowo oyika, mabowo oyikapo zomangira, mabowo ovundikira ndi mabowo ena apatali mu bolodi kuchokera m'mphepete mwa bolodi ndi wamkulu kuposa 3mm;

7. Chinthu chowotcha sichiyenera kukhala pafupi ndi waya ndi chinthu chopanda kutentha; chipangizo chotentha kwambiri chiyenera kugawidwa mofanana;

8. Soketi yamagetsi iyenera kukonzedwa mozungulira bolodi losindikizidwa momwe mungathere, ndipo socket yamagetsi ndi mabasi oyendetsa mabasi ogwirizanitsidwa nawo ayenera kukonzedwa kumbali yomweyo. Chisamaliro chapadera chiyenera kuchitidwa kuti musamapange zitsulo zamagetsi ndi zolumikizira zina zowotcherera pakati pa zolumikizira kuti zithandizire kuwotcherera zitsulo izi ndi zolumikizira, komanso kupanga ndi kumangirira zingwe zamagetsi. Makhazikitsidwe a masiketi amagetsi ndi zolumikizira zowotcherera ziyenera kuganiziridwa kuti zithandizira kulumikiza ndi kutulutsa mapulagi amagetsi;

9. Kukonzekera kwa zigawo zina: Zigawo zonse za IC zimagwirizana kumbali imodzi, ndipo polarity ya zigawo za polar imadziwika bwino. Polarity ya bolodi losindikizidwa lomwelo silingadziwike kupitilira njira ziwiri. Pamene mayendedwe awiri akuwonekera, mayendedwe awiriwa ndi olunjika kwa wina ndi mzake;

10. Mawaya pamwamba pa bolodi ayenera kukhala wandiweyani komanso wandiweyani. Pamene kusiyana kwa kachulukidwe kuli kwakukulu kwambiri, kuyenera kudzazidwa ndi zojambula zamkuwa zamkuwa, ndipo gululi liyenera kukhala lalikulu kuposa 8mil (kapena 0.2mm);

11. Pasakhale kudzera mabowo pa SMD ziyangoyango kupewa solder phala imfa ndi soldering zabodza zigawo zikuluzikulu. Mizere yofunikira yolumikizira sikuloledwa kudutsa pakati pa zikhomo zazitsulo;

12. Chigambacho chimagwirizana kumbali imodzi, chiwongolero cha khalidwe ndi chofanana, ndipo ndondomeko yoyikamo ndi yofanana;

13. Momwe kungathekere, zida za polarized ziyenera kukhala zogwirizana ndi njira yolembera polarity pa bolodi lomwelo.

10. Mawaya pamwamba pa bolodi ayenera kukhala wandiweyani komanso wandiweyani. Pamene kusiyana kwa kachulukidwe kuli kwakukulu kwambiri, kuyenera kudzazidwa ndi zojambula zamkuwa zamkuwa, ndipo gululi liyenera kukhala lalikulu kuposa 8mil (kapena 0.2mm);

11. Pasakhale kudzera mabowo pa SMD ziyangoyango kupewa solder phala imfa ndi soldering zabodza zigawo zikuluzikulu. Mizere yofunikira yolumikizira sikuloledwa kudutsa pakati pa zikhomo zazitsulo;

12. Chigambacho chimagwirizana kumbali imodzi, chiwongolero cha khalidwe ndi chofanana, ndipo ndondomeko yoyikamo ndi yofanana;

13. Momwe kungathekere, zida za polarized ziyenera kukhala zogwirizana ndi njira yolembera polarity pa bolodi lomwelo.
