Ut ex optima perficientur electronic circulos, inlayout de filis sunt momenti components et assituationem tabulae. Ad excogitandum boni low cost PCB. Principia haec tenenda; layout Primo consideremus, carissimi, PCB magnitudine. PCB in magnitudine est magna, typis lineas longis provenire augetur et minuitur facultas anti- strepitu et damno auctus est. Post magnitudine PCB est constituta, locum specialem ad hoc determinari components. Tandem signa circa functiones secundum omnes partes orbis pandenda sunt. Cum his verbis in principiis locating speciali consistit, â € Shorten nexum inter components ut summus frequency quantum fieri potest, ad redigendum experiri, et eorum mutua distribution parametri et electro intercessiones. Vulnerari non debet poni partes invicem propius et partes input et output quam longissime possent esse. ¡â quibusdam inter partes potentiales Sit alta et filis et brevi spatio distant per accidens augeri propter missionem. Consistit summa intentione fieri debet per debugging dura. â € ¢ lacinia pondus magis quam XV g debet praefigi uncis et tunc solidantur. Magna ista graves aestus generatum est apud alias partes non elit. Sed velit ut gb ad basim totius machinae calor dissipatio debere. Custodi scelerisque calefactio elementum elementum a. ④ For thelayout of adjustable components such as potentiometers, adjustable inductors, variable capacitors, and micro-switches, the structural requirements of the whole machine should be considered. If it is adjusted inside the machine, it should be placed on a printed board where it is easy to adjust. If it is adjusted outside the machine, its position should be compatible with the position of the adjustment knob on the chassis panel. According to the functional units of the circuit, thelayout of all components of the circuit must meet the following principles: ① Arrange the positions of each functional circuit unit according to the flow of the circuit, make thelayout convenient for signal circulation, and keep the signals in the same direction as possible. ② Take the core components of each functional circuit as the center and make alayout around it. The components should be pulled evenly, neatly and compactly on the PCB to minimize and shorten the leads and connections between the components. â € ¢ quia apud princeps operating frequentiis in circulos, et inter parametris distribution components potest considerari oportet. Generaliter disposita componentibus parallela esse quantum. Ita non modo pulchra, sed escendere facile pugil, frugum facilis massa. Â £ sita est super ripam components de circuitu tabula est plerumque non minus quam II mm ab extremis de circuitu tabula. Optimal de circuitu tabula est quadrangula rectangula sub figura. Ratio est quod ratio III, II et IV: 3. Cum magnitudinem circuitu tabula est maior quam CC mm CL mma est, mechanica vires in circuitu tabula potest considerari debet. wiring De principiis ita se habet: a filis input et output propter quod fugiendae conminuitoque quam maxime. Est optimum addere filum a terram feedback inter confirmabis ipsa fila ne initu generare coeperit. â € ¡minimum est latitudinem liminis maxime typis circuitu fila filis et determinari ad coniungere vires inter subiectum et in insulating ad valorem de current fluit per eos. Ex aeris crassitudine cum ffoyle sit et latitude patet I ad 0,05 mm XV mm in current non excedunt III ° C et per current II A. Itaque si filum sit latitudo 1.5 mm. Nam cursus integra praesertim digital circulos, 0.02 ad 0.3 mm latum molestie electorum solet. Scilicet, ut dum potes, utere wide fila filis maxime virtute et terram. Et minimum a spacing de filis maxime constituta pessimus-casu naufragii Nulla Botrytis cinerea et Sclerotium voltage. Nam integrated in circulos, praesertim digital circulos, quam diu processus concedit, in picem potest esse sicut parva quasi V ad VIII mm. â € ¢ Gloria typis Et flexus est fere circularis et rectus, vel includi ab angle non afficit perficientur in in electrica summus frequency cursus. Praeterea tentant vitare usum aeris in spatio magnam-ffoyle, aliter, quod facilius in aeris ffoyle tumescente putrescat et cadere quando tale incalescit coëunt diu. Ffoyle cum magna regio aeris sit usus, est optimum ad in malesuada euismod figura, qui conducit ex generatae praeter volatile Gas calefactio aeris inter tenaces ffoyle et positis distent. pad The pad center hole is slightly larger than the device lead diameter.pads that are too large are prone to false soldering. The pad outer diameter D is generally not less than d + 1.2 mm, where d is the lead hole diameter. For high-density digital circuits, the minimum pad diameter can be d + 1.0 mm.
