De modo calculi PCB linea latitudo et vena talis est;

Primum rationem crucis-sectionalis regionis Track. Folii aeris crassitudo maxima PCBS est 35um (si tu non es certus, petere potes fabricam PCB). Area sectionis transversalis multiplicatur latitudine lineae. Valor empirica habetur pro densitate currente vndique ab 15 ad 25 amperes per millimetros quadratos.

Expende crucem-sectionalem aream ut facultatem per-fluentem obtineas. I= KT0.44a0.75K is the correction coefficient. Generally, 0.024 is taken in the inner layer of copper clad wire, and 0.048t is taken in the outer layer as the maximum temperature rise, and the unit is Celsius (the melting point of copper is 1060℃). A is the cross-sectional area of copper clad, and the unit is square MIL(not mm mm, I is the maximum allowable current, the unit of amperes (AMP) is generally 10mil=0.010inch=0.254, which can be 1A, 250MIL=6.35mm, and is 8.3A data. The calculation of PCB current-carrying capacity has been lacking of authoritative technical methods and formulas. Experienced CAD engineers rely on personal experience to make more accurate judgments. Sed Novitio CAD, difficilis quaestioni occurrere dicitur non potest.

Current capacitas PCB deferendi pendet ab his factoribus: linea latitudo, linea crassitudo (foil crassitudo aenea), temperatura licita oritur. As we all know, the wider the PCB line, the greater the current-carrying capacity. Here, please tell me: assuming that 10MIL can withstand 1A under the same conditions, how much current can 50MIL withstand, is it 5A? Responsio sane nulla est. Linea latitudo in unitate Unciae (Unch = 25.4 millimetres) 1 oz. Copper = 35 micron crassus, 2 oz.=70 micron crassus, 1 oz = 0.035mm 1mil.=10-3inch. Trace Capacityper MIL STD 275

Gutta pressionis a resistentia fili longitudinis causata etiam in experimento considerari debet. Stanno in processu welds solum ad hodiernam capacitatem augendam adhibetur, sed difficile est volumen stagni regere. 1 OZ cupri, 1mm latum, plerumque 1-3 A galvanometer, secundum lineam longitudinis tuae, pressionis gutta requisita.

Maximus valor monetae debet esse maximus licitus valor sub temperatura ortus limitis, et fuse valor est valor temperatus ad quem punctum aeris liquescens pervenit. Eg. Temperatus 50 mil 1oz ortus 1060 gradus (id est punctum aeris liquescens), vena est 22.8A.
