Uyilo lwamacandelo akhethekileyo kwi PCB uyilo

1. Amacandelo aphezulu-frequency: Olona xhulumaniso lufutshane phakathi kwamacandelo aphezulu-frequency, kungcono, zama ukunciphisa iiparamitha zokusasazwa koqhagamshelo kunye nokuphazamiseka kwe-electromagnetic phakathi komnye nomnye, kunye namacandelo achaphazeleka lula akufuneki asondele kakhulu. . Umgama phakathi kwegalelo kunye namacandelo emveliso kufuneka ube mkhulu kangangoko.

2. Izixhobo ezinomahluko ophezulu onokuthi zibekho: Umgama phakathi kwamacandelo anomahluko aphezulu kunye nokudibanisa kufuneka kwandiswe ukuphepha umonakalo kumacandelo xa kwenzeka isiphaluka esifutshane ngengozi. Ukuze ugweme ukwenzeka kwe-creepage phenomenon, ngokuqhelekileyo kufuneka ukuba umgama phakathi kwemigca yefilimu yobhedu phakathi kwe-2000V enokubakho umahluko kufuneka ube mkhulu kune-2mm. Kumahluko aphezulu anokubakho, umgama kufuneka unyuswe. Izixhobo ezinombane ophezulu kufuneka zibekwe ngokukhawuleza kangangoko kunokwenzeka kwindawo ekungelula ukufikelela kuyo ngexesha lokulungisa.

3. Izixhobo ezinobunzima obuninzi: Ezi zixhobo kufuneka zilungiswe ngamabakaki, kunye namacandelo amakhulu, anzima, kwaye avelise ubushushu obuninzi akufanele afakwe kwibhodi yesiphaluka.

4. Izinto ezifudumalayo kunye nobushushu: Qaphela ukuba izixhobo zokufudumeza kufuneka zibe kude nezixhobo ezithintela ukushisa.
