Mfundo zosamalira ma board a PCB (ma board ozungulira)

Pankhani yokonza matabwa PCB dera, basi soldering makina amapereka mayiko kwa soldering wa matabwa PCB dera, koma mavuto nthawi zambiri zimachitika popanga matabwa PCB dera, zomwe zingakhudze khalidwe solder.Pofuna kukonza zotsatira za mayeso, kukonza zina zaukadaulo ziyenera kuchitidwa pa bolodi lokonzedwa musanayesedwe pa intaneti pa bolodi yadera la PCB kuti muchepetse kusokoneza kosiyanasiyana pamayeso.Njira zenizeni ndi izi:
.Kukonzekera mayeso asanayesedwe

Short-circuit the crystal oscillator (tcherani khutu ku mapini anayi a crystal oscillator kuti mudziwe kuti ndi mapini awiri ati omwe ali mapini otulutsa chizindikiro ndipo amatha kufupikitsa zikhomo ziwirizi. sayenera kufupikitsidwa !!) Kwa mphamvu yayikulu ya electrolytic The capacitor iyeneranso kugulitsidwa pansi kuti itseguke.Chifukwa kulipiritsa ndi kutulutsa kwa ma capacitor akuluakulu kungayambitsenso kusokoneza.

2. Gwiritsani ntchito njira yopatula kuyesa PCB dera bolodi chipangizo

Pakuyesa pa intaneti kapena kuyesa kufananitsa kwa chipangizocho, chonde tsimikizirani mwachindunji zotsatira zoyeserera ndikujambulitsa chida chomwe chapambana mayesowo (kapena kuti ndichabwinobwino).Ngati mayeso alephera (kapena sakulekerera), akhoza kuyesedwanso.Ngati ikulepherabe, mukhoza kutsimikiziranso zotsatira zoyesa poyamba.Izi zimapitilira mpaka chipangizo chomwe chili pa bolodi chiyesedwe (kapena kufaniziridwa).Kenako gwiranani ndi zida zomwe zalephera mayeso (kapena zomwe zalephera).

Zida zina zoyesera zimaperekanso njira yocheperako koma yothandiza kwambiri pazida zomwe sizingadutse mayeso a pa intaneti a ntchitoyi: chifukwa mphamvu yoperekera chida choyesera ku board board itha kugwiritsidwanso ntchito pamagetsi ofananirako ndi mphamvu yofananira. kuperekera kwa chipangizocho kudzera pa clip yoyeserera.Ngati pini yamagetsi ya chipangizocho yadulidwa pa pini yapansi, chipangizocho chidzachotsedwa ku dongosolo lamagetsi la board board.
Panthawiyi, yesetsani kuyesa pa intaneti pa chipangizocho;popeza zida zina pa PCB sizikhala ndi mphamvu zogwira ntchito kuti zithetse kusokoneza, zotsatira zenizeni zoyezetsa panthawiyi zidzakhala zofanana ndi "mayeso a quasi-offline".Mlingo wolondola udzakhala wapamwamba kwambiri.Kusintha kwakukulu.
